The casino wiki

Betting the entirety of one's remaining chip stack in a single action. The player can only win from any opponent up to the amount matched from their own stack; overflow chips create side pots between other players still in the hand.

A mandatory bet placed before cards are dealt in games like Three Card Poker, Caribbean Stud, or in tournament poker after the first level. Distinct from a bet placed during the hand.

Australian gaming manufacturer whose land-based pokies (Buffalo, Dragon Link, Lightning Link) heavily influenced online slot design. Digital versions of many Aristocrat titles run at select online casinos, particularly those serving the Australian market.

A slot feature that allows the player to set a number of consecutive spins to be played automatically without clicking spin each time. Typically capped at 100 spins per activation; some regulators (including UKGC) have restricted or banned autoplay entirely.

A comparing card game where the player bets on whether the "player" hand, the "banker" hand, or a "tie" will have a total closest to 9. Historically favoured by high rollers due to its low house edge on player (1.24%) and banker (1.06%) bets.

The total amount of money a player has set aside for gambling. Sound bankroll management involves setting session limits, never wagering more than a small percentage on any single bet, and treating the bankroll as sunk cost rather than money to be recovered.

A withdrawal method where casino winnings are sent directly to the player's bank account. Typically the slowest method (3-5 business days) but supports the largest transaction sizes and is universally available.

The mathematically optimal set of decisions for a blackjack player given only their two cards and the dealer's upcard. Following basic strategy correctly reduces house edge to below 1% at standard rulesets; deviations cost significantly more than most players realise.

A feature at some live-dealer tables allowing a spectator to place a bet backing an active player's hand without participating in the decisions. The result follows whatever the active player chose to do.

A platform where players bet against each other rather than against a bookmaker. The exchange takes a commission on winning bets (typically 2-5%) rather than building margin into odds. Betfair is the largest example.

A blackjack variant where the player is dealt two hands and may switch the top card of each hand once before playing. Compensates house with modified rules (dealer 22 pushes on unbusted player hands, blackjack pays 1:1).

Mandatory bets posted by two players seated left of the dealer button in Texas Hold'em (the small blind and big blind). Blinds create a starting pot each hand and rotate around the table.

Any pattern of play designed primarily to extract value from bonus offers rather than to play games entertainingly. Includes creating multiple accounts, playing prohibited games during wagering, and betting patterns that only make sense for locking in bonus value. Operators void bonuses and winnings when abuse is detected.

The portion of a player's total account balance made up of bonus funds subject to wagering requirements. Wagering must complete before the bonus balance converts to cash and becomes withdrawable. Separated from the cash balance in most cashiers.

The physical location at a land-based casino where chips are exchanged for cash and vice versa. In online contexts, "cage" sometimes refers to the withdrawal processing team.

The practice of tracking cards dealt from a blackjack shoe to inform betting and playing decisions. Legal but disfavoured by casinos; live-dealer online studios reshuffle after each hand or use continuous shufflers to defeat counters.

A promotional refund of a percentage of net losses over a defined period, typically weekly. Cashback usually credits with zero wagering, making it more valuable per dollar than matched-deposit offers.

See: Best cashback bonuses

The interface where players deposit, withdraw, and manage payment methods. Cashier speed and rail options substantially affect the player experience beyond the games themselves.

A reversal of a card payment initiated by the player through their bank. Chargebacks against gambling deposits result in account closure at any legitimate operator, and often blacklisting across the operator's group.

A complimentary reward from a casino, typically at land-based venues (free rooms, meals, show tickets) but also online (deposit matches, free spins) tied to activity level.

A dice game where players bet on the outcome of a shooter's rolls. Craps has one of the lowest house edges in the casino when the correct bets are made (Pass Line + free odds at 1.4%) and one of the highest when they aren't (Any 7 at 16.7%).
