Your Ultimate Guide to Popular Casino Games and How to Play Them
Tired of the same old routines and craving a thrill? Casino games offer a simple escape, letting you test your luck with a spin of the wheel or a hand of cards from the comfort of your own home. The core mechanics are easy to learn, with clear rules and instant feedback so you can jump right into the action. Whether playing for small stakes or just for fun, you get the immediate excitement of chance and the potential for a quick win.
Understanding the House Edge in Popular Gambling Activities
The house edge in popular gambling activities represents the mathematical advantage a casino holds over players, built into the rules of every game. In roulette, the American double-zero wheel carries a 5.26% house edge, while European single-zero reduces it to 2.70%, directly affecting long-term loss expectancy. Blackjack offers one of the lowest edges—often under 1% with basic strategy—but deviations increase the games not on gamstop casino’s take. Slot machines vary wildly, with edges typically ranging from 2% to 15% depending on the game and denomination. Craps line bets like the pass line carry around a 1.41% edge, while proposition bets can exceed 10%. Understanding this fixed percentage is critical, as it dictates expected losses over time, regardless of short-term variance. The edge is not a guarantee of outcome but a statistical certainty over thousands of rounds.
How probability shapes outcomes in card and table games
In card and table games, probability dictates every possible outcome, so knowing the math directly impacts your choices. In blackjack, the removal of cards from the deck shifts probabilities in real time, telling you when to hit or stand based on the dealer’s upcard. For craps, the dice roll outcomes follow strict probability distributions, making the Pass Line bet far less risky than a hardway proposition. Roulette’s single-zero wheel gives the house a fixed edge because the odds of hitting one number are always 37 to 1, not 36 to 1. Understanding these odds helps you avoid sucker bets that seem tempting but have poor probability.
- Blackjack card counting relies on probability shifts as cards are dealt from the shoe.
- In craps, the probability of rolling a 7 is six times higher than rolling a 2.
- Roulette’s green zero slots create a probability disadvantage for all outside bets.
The long-term statistical advantage built into every wager
Every wager in a casino is engineered with a hidden, immutable edge that guarantees profit over time, regardless of short-term luck. This built-in statistical advantage ensures that, while a player might win a few rounds, the game’s mathematical structure gradually funnels money back to the house. For example, a roulette wheel’s extra green numbers create a permanent imbalance, and blackjack’s requirement for the dealer to act last crafts an unavoidable probability tilt. You cannot outrun this design; accepting it is the only way to gamble with clear eyes, understanding that each bet is a tiny, voluntary surrender of long-term value.
Why the math always leans toward the operator
The math always leans toward the operator because every casino game is built on a structural mathematical advantage that guarantees profit over time. This edge is embedded in the game’s rules—e.g., the single zero on a roulette wheel or the blackjack dealer acting last. Payouts are deliberately set below true odds; for instance, a winning bet on a single roulette number pays 35-to-1, while the actual probability is 37-to-1. This discrepancy ensures that, over millions of spins or hands, the expected value remains negative for the player. The operator’s margin is not a bug but a calculated feature, making long-term losses for players mathematically inevitable.
The house edge is a fixed mathematical subtraction from every wager, ensuring the operator always profits in the aggregate.
Mastering the Art of Strategic Card Play
Mastering the art of strategic card play in casino games requires discipline beyond knowing basic rules. In blackjack, you must internalize the basic strategy chart to reduce the house edge by minimizing errors on every hit, stand, double, and split decision. For poker variants like Three Card Poker, optimal play often hinges on understanding when to fold based on your hand’s value against the dealer’s upcard, rather than chasing potential flushes. A nuanced layer involves recognizing that variance dictates short-term results, meaning even perfect strategy does not guarantee consecutive wins. In baccarat, strategic card play is limited, yet tracking the banker bet’s lower house edge and ignoring pattern-based systems remains the only mathematically sound approach, as no betting progression alters the fixed odds of each draw.
Core rules and betting patterns in classic 21
In classic 21, the core rule is to beat the dealer without exceeding 21. You get two cards, can “hit” for more or “stand” to lock your total. Aces count as 1 or 11, and face cards are ten. The most fundamental betting pattern is to match your wager to the dealer’s upcard—betting small when they show a strong card like a ten. Doubling down allows you to double your bet for one extra card, often optimal when you hold 11. Always split aces and eights, never split tens.
Core rules: get as close to 21 as possible without going bust. Betting patterns: adjust your wager based on the dealer’s visible card, and use doubling down or splitting to maximize advantage in favorable hands.
When to split pairs, double down, or stand firm
In blackjack, splitting pairs and doubling down depend on the dealer’s upcard. Always split aces and eights; never split tens or fives. Double down on 11 against any dealer card, or on 10 versus 9 or lower. Stand firm on hard 17 or above, and on 12–16 when the dealer shows 2–6. Conversely, hit on soft 17 or lower, or when the dealer has a 7 or higher. These decisions follow basic probability to minimize the house edge.
Split aces and eights, double on 11, stand on hard 17+ or against dealer bust cards; otherwise, hit.
Card counting myths and legal considerations
Many players believe card counting is illegal, but this is a myth; casinos are private establishments and can ban players for any perceived advantage play, including counting, but it is not a criminal offense. A common myth is that counting requires a photographic memory, whereas basic Hi-Lo strategies rely on simple addition. Legally, using your mind to track cards is permissible, but using electronic devices to aid counting crosses into illegality in most jurisdictions. Casinos employ countermeasures like shuffling more frequently, which makes counting impractical in many modern games.
- Card counting is not illegal, but casinos reserve the right to ban counters.
- Effective counting relies on tracking ratios, not memorizing every card.
- Using mechanical or electronic aids is typically illegal.
- Frequent shuffling and automatic shufflers render counting ineffective in most casinos today.
The Spin of Chance: Mechanical and Digital Reels
The Spin of Chance: Mechanical and Digital Reels represents the core physical and virtual engine of slot-based casino games. On classic mechanical reels, physical stops and weighted symbols create a fixed probability for each spin, directly tied to the machine’s hardware layout. Digital reels use a random number generator (RNG) to map virtual stops to displayed symbols, allowing for more complex pay tables and multi-line configurations without moving parts. Whether the reels are brass-and-gear or pixel-driven, the outcome of each spin is independent of the last.
The key insight is that a reel’s stopping position is purely a snapshot of a random number at the instant you press spin—digital or analog, the result is locked before any animation plays.
For practical play, treat both the same: no sequence matters, only the return-to-player percentage embedded in the game’s design.
How random number generators determine symbol alignment
In digital slot reels, a Random Number Generator (RNG) produces a constant stream of numbers, even when the machine is idle. When you press spin, the system captures the exact millisecond’s RNG output, which maps to a specific position on a virtual reel strip. This virtual position is then translated into the visible symbol stop point, determining alignment. The RNG-based reel mapping ensures that each spin outcome is independent, as the generated number dictates which symbols line up across paylines without mechanical influence.
- Each millisecond’s RNG output corresponds to a unique virtual reel coordinate, not a physical stop.
- The mapping table assigns generated numbers to symbol positions, controlling which icons appear on the payline.
- Outcomes are determined at the instant of spin initiation, not during reel deceleration.
Paylines, volatility, and return-to-player percentages
Paylines define the active patterns across reels that trigger a win, with more lines increasing hit frequency but often requiring higher bets. Volatility dictates the risk: low-volatility games deliver small, frequent payouts, while high-volatility slots offer larger but sporadic wins. The return-to-player percentage mathematically predicts long-term theoretical payback, typically between 94% and 98%, but does not guarantee short-term results. A high RTP on a high-volatility slot can still produce long dry spells, so aligning these three factors with your bankroll and play style is essential for managing expectations.
Progressive jackpots vs fixed prize pools
When you choose between progressive jackpots and fixed prize pools, you’re weighing a life-changing windfall against a stable, predictable payout. A fixed prize pool guarantees a set maximum reward per spin, offering a clear ceiling you can calculate. In contrast, a progressive jackpot grows with every player’s bet across a network, creating massive pooled prizes that can spike unpredictably. This trade-off is direct: fixed pools provide consistent, modest wins and reliable odds, while progressives sacrifice frequent payouts for the slim chance at a colossal hit. Your decision hinges on whether you value stability or the thrill chasing an ever-growing pot.
Wheel-Based Games of Pure Luck
In casino games, wheel-based games of pure luck like the Big Six or Money Wheel offer no strategic input; each spin is an independent, random event. Your sole actionable decision is betting on which symbol or segment will land under the pointer, as the physical wheel’s balance and bearing friction ensure true randomness. Payouts are inversely tied to a segment’s size—the smaller the slot, the higher the multiplier, but the lower your probability of winning. Always check the wheel’s visible paytable; some segments, like the joker or casino logo, may return less than the true odds demand, creating a higher house edge. Treat these games as pure entertainment, never as a path to profit. Focus on low-volatility bets (large segments) to extend playtime, as they offer frequent small wins despite lower return-to-player percentages.
Understanding European, American, and French wheel variations
Understanding European, American, and French wheel variations is crucial for any roulette player. The American wheel includes an extra 00 pocket, raising the house edge to 5.26%, while the European single-zero wheel cuts it to 2.7%. The French variation uses the same single-zero layout but introduces “La Partage” and “En Prison” rules, which return half your even-money bet on a zero. This subtle rule difference can halve the house edge further on even-money bets, making French roulette the most player-friendly version.
Q: What is the main practical difference between American and European wheels?
A: The American wheel’s double-zero pocket significantly increases the house edge, making European or French wheels a smarter choice for your bankroll.
Inside bets, outside bets, and their respective odds
In roulette, inside bets and outside bets offer vastly different odds. Inside bets target specific numbers or small groups, such as a single number (35:1 payout, 2.70% European wheel), split (17:1, 5.41%), or street (11:1, 8.11%). Outside bets cover larger sections, like red/black or odd/even, with nearly 50% probability but lower 1:1 payout. To place a bet, follow this sequence:
- Select inside for high risk, high reward, or outside for frequent small wins.
- Place chips on the inner number grid (inside) or outer boxes (outside).
- Wait for the wheel spin; inside bets pay more but win less often.
The allure of betting systems like Martingale and Fibonacci
The allure of betting systems like Martingale and Fibonacci in pure-luck wheel games is the illusion of control over random outcomes. Players are drawn to the simple math: Martingale promises to recover losses with one win by doubling bets after a loss, while Fibonacci’s sequence offers a slower progression that feels safer. This appeals to a gambler’s desire to turn a negative-expectation game into a perceived winning strategy. The practical user trap is that these systems require immense bankrolls and hit table limits, breaking the progression. They exploit the gambler’s fallacy, but cannot alter house odds.
Q: Why do players cling to Martingale or Fibonacci despite inevitable losses? A: Because the systems provide short-term wins and a structured plan, masking the fact that one extended losing streak—statistically certain over time—wipes out all gains.
Baccarat: Elegance Meets Simplistic Betting
Baccarat embodies a unique duality within casino games, merging an aura of high-stakes glamour with remarkably straightforward rules. Players choose only to bet on the Player, the Banker, or a Tie, leaving all card-drawing actions to the dealer. This simplicity removes strategic complexity, making it instantly accessible to newcomers while retaining the prestige often associated with sophisticated table play. The low house edge on Banker bets (around 1.06%) further enhances its appeal as a practical, user-friendly option. Unlike games requiring constant decisions, Baccarat: Elegance Meets Simplistic Betting allows participants to focus on the rhythm of the game and its refined atmosphere.
Player, banker, and tie wagers explained
In Baccarat, the core action revolves around three distinct bets. The Player and Banker wagers explained reveal a straightforward choice: bet on which hand will come closest to nine, with both options offering near-even odds after a built-in house commission on Banker wins. The Tie wager pays significantly higher—typically 8:1 or 9:1—but carries a steep house edge, making it a riskier, high-reward play for thrill-seekers. Each round, cards are dealt according to fixed rules, removing any player decision beyond placing your chip on one of these three outcomes.
The game’s simplicity lies in choosing between Player, Banker, or Tie—the Banker bet offers the best odds, while Tie pays big but hits rarely.
The role of commission and minimal skill requirements
In Baccarat, the minimal skill requirements make the commission on the Banker bet a key strategic cost. Commission, typically 5%, is deducted from winning Banker wagers to offset the game’s built-in house edge. Because you make no playing decisions—just choose Player, Banker, or Tie—your only task is factoring that commission into your bet sizing. The sequence is clear:
- Place a bet on Banker.
- Wait for the hand to resolve automatically.
- If Banker wins, accept the 5% commission deducted from your payout.
This single, passive rule keeps the game elegant while directly impacting your net returns without requiring any card-counting or strategy memorization.
Why high rollers favor this low-house-edge option
High rollers favor baccarat’s banker bet because its 1.06% house edge maximizes returns on massive wagers. Unlike other games, this low-house-edge option minimizes the casino’s mathematical advantage during high-stakes play. The simplicity eliminates costly strategy errors that plague other tables. For players moving thousands per hand, the banker bet’s statistical certainty preserves bankroll longevity. The 5% commission on banker wins feels negligible when compared to the consistent edge savings. This structure lets high rollers focus purely on bet sizing and pace, not complex decisions that erode value. Baccarat’s banker wager remains the most efficient tool for controlling variance while deploying substantial capital.
Poker Variations That Rely on Strategy
In the casino, where luck often steals the spotlight, Texas Hold’em stands as a pure test of strategic will. You sit across from a player who has raised every hand, and you know that folding weak cards is a victory in itself. Omaha Hi-Lo demands a different kind of math, forcing you to read the board for both high and low potential, splitting pots with precise calculation. Seven-Card Stud strips away community cards, turning the game into a memory battle where you track every exposed card to deduce your opponent’s hidden strength. These variations reward patience and probability over impulse, making every decision a calculated risk within the casino’s structured chaos. The real winnings come from outthinking the table, not outdrawing the dealer.
Texas Hold’em hand rankings and betting rounds
In Texas Hold’em, your strategy hinges on knowing the hand rankings and betting rounds inside out. You start with two hole cards, then the flop, turn, and river reveal community cards. Each round—pre-flop, flop, turn, and river—offers a chance to check, bet, raise, or fold. Your hand’s strength shifts with every card; a pair on the flop might become a flush on the river. Mastering when to bet big on a strong hand or fold a weak one is key to outplaying opponents.
Bluffing techniques and reading opponents
Mastering reading opponents’ physical tells starts with spotting involuntary reactions to strong hands, like sudden stillness or shallow breathing. Bluffing techniques rely on selectively representing a narrow range of possible holdings, then betting consistently with that story. In stud or hold’em variations, pay attention to bet timing—a quick raise often signals weakness. Reverse tells, like sighing before a big bet, work only if your opponents notice and believe them. Control the narrative by occasionally showing bluffs to build a deceptive image.
Reading opponents involves observing unconscious patterns; bluffing requires crafting a credible, consistent story that exploits those patterns.
Tournament play versus cash game dynamics
Tournament play and cash game dynamics diverge primarily in risk management and strategic depth. In a tournament, chip preservation is critical as blinds rise on a fixed schedule, forcing aggressive plays to avoid elimination; the finite entry creates a zero-sum structure where survival outweighs profit. Conversely, cash games allow constant rebuying, meaning players focus on expected value per hand rather than survival. Key strategic differences include:
- Stack depth: Tournaments often induce short-stack play late, while cash games typically permit deeper, more complex post-flop maneuvers.
- Risk tolerance: Cash games reward calculated bluffs over survival, whereas tournament play demands tighter folds to conserve chips.
- Goal orientation: Prize ladder considerations in tournaments create bubble strategies absent in cash games.
Live Dealer Experiences in the Digital Age
To maximize a live dealer session, prioritize tables with multiple camera angles, as they reveal the shoe mechanics and dealer actions in real time, ensuring game integrity. Interact with the studio via the chat function to ask the dealer about their shuffle speed or rule variations, which can inform your betting strategy. Focus on game speed, as some tables offer a slower pace perfect for analyzing outcomes, while rapid-fire rounds suit progressive betting systems. For blackjack, confirm the dealer stands on soft 17; for roulette, use the statistical history display to track number frequencies over the last 50 spins, a feature exclusive to digital tables.
Streaming technology bridging virtual and real tables
Streaming technology erases the distance between your screen and the felt, turning a click into a seat at a live table. Real-time video bridging now syncs digital bet buttons with physical card movements, so a dealer’s shuffle in a studio directly affects your virtual hand. High-definition cameras capture every chip stack and roulette spin, while latency is crushed to under a second, making reactions feel instant. You can chat with the dealer and see them acknowledge your play, merging the remote interface with the organic flow of a real casino floor. This hybrid feed delivers authentic tension without needing to travel, keeping the human element alive through your browser.
Interaction with croupiers via chat and camera
Direct interaction with croupiers via chat and camera transforms digital blackjack or roulette into a social, transparent event. You type questions about game flow in real-time, and the dealer responds verbally, often calling you by name. The camera focuses on the dealer’s hands as they shuffle or spin, building trust through visible, physical action. Real-time dealer chat allows you to request specific table speeds or clarify rules without leaving your seat. How can chatting with a croupier improve my betting strategy? It lets you ask experienced dealers for tips on bet placement or payout timing, giving you an edge that automated games cannot offer. This direct, human connection makes each hand more engaging and accountable.
Trust and transparency in automated card dealing
In live casino games, automated card dealing transparency hinges on visible shuffling mechanics and real-time deal logs. Players want proof that no manual intervention alters outcomes. You can watch the auto-shuffler sequence each round, and a digital audit trail confirms card origins. How does the system prove no rigging mid-deal? The dealing unit uses a random number generator verified by independent testers, with every card movement tracked and displayed on your screen. This eliminates human error or suspicion, letting you trust the automated process as purely chance-based. The interface even shows the cut card position, making the algorithm’s fairness tangible with every hand.
Specialty Games Beyond the Norm
Specialty games beyond the norm in casinos break from traditional table and slot formats, offering unique mechanics like virtual scratch cards, keno-based hybrids, or wheel-spinning games with skill-based bonus rounds. These titles often feature rapid rounds and simplified rules, making them ideal for casual play without complex strategies. For example, a “deal or no deal” simulator or a digital fishing game introduces narrative elements absent in standard blackjack or video poker. Unlike slots, these games rarely rely on paylines, instead using instant-win triggers or volatile payout tables for their outcomes. Players should check the house edge and max bet limits, as these can vary widely between titles. They provide a low-pressure alternative for those seeking novelty over deep engagement.
Keno, bingo, and their randomized number draws
Keno and bingo are specialty games where players wager on randomized number draws rather than skill or strategy. In keno, you choose up to 20 numbers from 1–80; a machine then draws 20 numbers, and prizes increase based on how many match. Bingo uses a cage with numbered balls—typically 75 or 90—that are called one by one; you mark cards and win by completing a predetermined pattern first. Both games rely entirely on random number generators or mechanical ball mixers, ensuring each draw is independent. Players simply pick their numbers or cards and wait for the draw, with no interactive decisions after the bet is placed.
Keno and bingo center on randomized number draws where players select numbers or mark cards, then await machine- or cage-drawn results that determine wins solely by chance.
Scratch cards and instant-win digital alternatives
Scratch cards offer a tangible, low-stakes thrill where players physically reveal hidden symbols for instant payouts, bypassing complex rules entirely. Their digital counterparts replicate this rush with interactive virtual reveals, often featuring themed animations or cascading layers that build suspense. Unlike slot spins, these instant-win digital alternatives provide direct outcomes without reels or paylines, letting players see results in a single tap or click. Both formats appeal to casual users seeking quick gratification, with digital versions frequently introducing bonus mini-games or progressive multipliers hidden beneath virtual foil.
Sic Bo and the appeal of three-dice combinations
Sic Bo captivates players by offering a vast spectrum of outcomes through its core mechanic: the random tumble of three dice. Unlike blackjack or baccarat, the appeal lies in the sheer combinatorial depth, where a single roll can land on a specific triple, a high or low total, or a unique two-number combo. This variety shifts decision-making away from static strategy toward reading probability across dozens of bets. The central draw is the **prediction of specific three-dice combinations**, as each wagered choice—from a Small/Big bet to a precise Triple—carries a distinct risk and reward profile, creating a purely chance-driven puzzle with every shake of the dice.
- Players choose between 50+ bet types, from simple “Big” (total 11–17) to long-shot “Specific Triples” (e.g., three 6s).
- The three-dice mechanic creates built-in tension: a single roll resolves multiple overlapping wagers simultaneously.
- Combination bets (e.g., “any two dice showing a 4 and 5”) offer an intermediate risk level between low-payout totals and high-payout triples.
Bankroll Management for Sustained Play
Bankroll management for sustained play means setting a strict loss limit before you start any casino game session. Never risk more than a small, fixed percentage of your total session bankroll on a single hand, spin, or bet, ensuring you can withstand losing streaks. Separate your gambling funds from living expenses entirely, as this prevents emotional decisions that erode longevity. Q: What is the most critical rule for sustained play? A: Always stop playing once you hit your pre-set loss limit, regardless of how close you are to a win, because chasing losses ends your session prematurely.
Setting loss limits and win goals before sitting down
Before engaging with any casino game, pre-determine your loss limits and win goals to ensure disciplined play. First, set a fixed loss limit—the maximum cash you will risk in a session—and walk away immediately if hit. Second, define a realistic win goal, a specific profit target at which you will cash out. Follow this sequence:
- Calculate your session bankroll (e.g., $200).
- Set your loss limit at 50% ($100).
- Set your win goal at 30% ($60).
- Leave the session upon reaching either boundary.
This method prevents chasing losses and protects profits, turning a volatile evening into a controlled venture.
Unit betting and percentage-based staking plans
Unit betting keeps you disciplined by assigning a fixed value, like $5, to every bet, shielding your bankroll from emotional swings. Percentage-based staking plans, such as risking 2% of your current total per wager, dynamically adjusts bet size as your bankroll fluctuates. For slot play, a flat unit system prevents overbetting after a win, while a percentage approach shrinks your stake after losses to avoid ruin. Switching between plans mid-session can muddle your risk management, so stick with one for consistency.
Unit betting standardizes wagers, while percentage-based plans scale them with your bankroll, both aiming to extend play time through controlled risk.
Avoiding the sunk cost fallacy in losing streaks
A losing streak can trigger the sunk cost fallacy, where you chase losses in an attempt to recover money already spent. This is a direct threat to bankroll management. Instead, view each session as an independent event. Set strict loss limits before you start and adhere to them without exception. When you hit that limit, stop playing immediately. To break the cycle, follow this clear sequence:
- Pause and physically walk away from the game.
- Accept the session loss as a fixed cost of play.
- Redeposit only after a planned break, never on impulse.
This discipline preserves your bankroll for future wins, not past losses.
Mobile Platforms and On-the-Go Wagering
Modern mobile platforms transform casino games into an immediate, handheld experience, allowing you to spin slots or hit blackjack from a commute. The tactile interface is optimized for touch, with one-tap betting and auto-play features that speed up wagering in short bursts. Game libraries shrink or expand based on device storage, but major titles adapt seamlessly to any screen size, ensuring no loss of visual or audio quality. Live dealer games now stream directly to your phone, letting you place side bets while waiting in line. The real edge is on-the-go wagering—you can cash out a hand seconds before a notification disrupts your stride. This isn’t desktop play downsized; it’s a dedicated, reactive ecosystem for instant stakes.
Touchscreen adaptations for smooth finger-based navigation
Modern mobile casino platforms implement touchscreen adaptations for smooth finger-based navigation by increasing the size of interactive zones for spin buttons, bet adjusters, and card selections, preventing accidental taps. Developers employ inertia scrolling for game lists and chip trays, allowing fluid flick gestures to stop naturally without abrupt halts. Haptic feedback provides subtle vibrations for key actions like placing a bet or confirming a deal, confirming input without requiring user to look away. Edge swipes are suppressed to avoid triggering system controls mid-game, ensuring every finger movement directly corresponds to intended in-game action.
App-exclusive bonuses and optimized graphics
Exclusive mobile bonuses await only within the casino app, often delivering a hefty deposit match or free spins immediately upon first login. These app-only rewards typically follow a clear sequence:
- Download the native app from the official store.
- Trigger the bonus with a unique promo code or automatic pop-up.
- Use the extra chips on optimized graphics slots that load in seconds, featuring crisp, touch-responsive reels and fluid 3D animations. You won’t find this visual polish or the bonus tier on a standard browser site.
Security protocols for mobile payment transactions
When depositing or withdrawing from casino apps, tokenization replaces sensitive card details with a unique digital identifier, ensuring actual account numbers are never stored on the device or transmitted over networks. End-to-end encryption then scrambles transaction data from the point of entry to the payment processor, making intercepted information unreadable. Biometric authentication, such as fingerprint or facial recognition, adds a device-specific layer that a stolen password alone cannot bypass. Additionally, session tokens expire immediately after a transaction completes, preventing replay attacks. These layered protocols collectively secure the payment route without requiring user configuration.
