Understanding Terminology and Safer Play
Understanding some of the most common online casino terms will enable you to make smarter and more responsible decisions. This is a list of some of the most common gameplay, bonus, and responsible gambling terms.
If gambling is causing a problem or financial issues, assistance is available through provincial programs.
A
Accumulator: A wager combining multiple events on one bet slip. All selections must win for the bet to pay out, creating higher potential payouts but lower overall odds of success.
All-in: When a player bets their entire chip stack on a single hand or round. In poker, this allows players with fewer chips to stay in the hand for a portion of the pot.
Ante: A small mandatory bet placed by all players before a hand begins. Common in poker variants, it ensures there is a starting pot before any cards are dealt.
Autoplay: A slot feature that automatically spins the reels for a set number of rounds or until preset limits are reached. It does not change the game’s odds or RTP.
B
Bankroll: The total amount of money a player sets aside for gambling. It can refer to a casino account balance or a broader budget used across multiple sessions or platforms.
Banker: One of the two main betting options in baccarat, alongside the player bet. Banker bets typically have a slightly lower house edge but often include a small commission on winnings.
Bet Refund: A promotion that returns part of a losing wager, usually as bonus funds. These funds often come with wagering requirements and specific terms set by the casino.
Betting Limits: The minimum and maximum amounts that can be wagered on a game or table. Limits vary depending on the game, platform, and sometimes the player’s account level.
Bust: In blackjack, a hand that exceeds a total value of 21. When a player or dealer busts, the hand automatically loses.
Buy-in: The amount required to enter a game or casino tournaments. In cash games it determines the starting chip stack, while tournament buy-ins typically include a prize pool contribution and a fee.
C
Card Counting: A blackjack strategy that tracks high and low cards remaining in the deck to estimate advantage. Casinos typically prohibit it, and it is ineffective in most online games that reshuffle after each hand.
Casino Lobby: The main interface of an online casino where players browse games, access account settings, and view categories such as online slots, table games, or live dealer titles.
Cold Streak: A period of consecutive losses during play. Cold streaks are part of normal variance and do not affect the statistical odds of future outcomes.
Comp Points: Loyalty points awarded based on wagering activity. They can sometimes be exchanged for rewards such as bonus funds, free spins, or other program benefits.
Croupier: The dealer who manages table games such as blackjack, roulette, or baccarat. In online live dealer games, the croupier appears via video stream from a studio.
Cryptocurrency: Digital currencies such as Bitcoin or Ethereum that operate on blockchain networks. Some online casinos in Canada, including many bitcoin casinos, now accept digital currencies – though transactions may involve network fees and price volatility.
D
Dealer: The person or system responsible for dealing cards and managing table game rounds. In live dealer games this is a real person, while RNG games use software.
Deposit Bonus: A promotion that adds bonus funds or free spins when a player deposits money. These bonuses usually come with wagering requirements before withdrawals are allowed.
Double Down: A blackjack strategy that allows players to double their original bet after receiving their first two cards and take exactly one additional card.
E
Edge: The mathematical advantage held by one side in a betting situation. In casino games, this usually refers to the house edge.
En Prison: A rule in some European roulette games where even-money bets that land on zero remain active for the next spin instead of losing immediately.
Even-Money Bets: Wagers that pay 1:1, returning the original stake plus an equal amount in winnings. Examples include red/black bets in roulette.
Expanding Wilds: A slot feature where a wild symbol expands to cover an entire reel, increasing the chances of forming winning combinations.
F
Flat Betting: A wagering approach where the same bet amount is placed each round. It does not change the house edge but can help structure session spending.
Fold: In poker, choosing to withdraw from a hand and forfeit any chips already placed in the pot.
Free Spins: A slot bonus allowing players to spin reels without using their own funds. Winnings are often subject to wagering requirements.
Freeroll: A tournament with no entry fee that still offers prizes. Freerolls are commonly used as promotional events.
Full House: A poker hand consisting of three cards of one rank and two of another. It ranks above a flush and below four of a kind.

Gamble Feature: An optional slot feature that lets players risk winnings on a secondary game for a chance to increase the payout.

H
High Roller: A player who regularly places large wagers. Casinos may offer these players higher limits and VIP benefits.
