Casino & Sports Betting Glossary for Canadian Players

Confused by gambling jargon? This plain-English glossary explains common casino and sports betting terms you’ll see on WillHills and at Canadian gambling sites. It’s designed for beginners – no hype, no fluff.

Bookmark this page and refer back any time you run into a term you don’t recognize. As we expand our guides, we’ll keep adding more definitions here.

A–C

Action
Any money you have at risk on a game or event. If you have $20 on tonight’s NHL game, you “have action” on it.
Bankroll
The total amount of money you’ve set aside specifically for gambling or betting – money you can afford to lose.
Bonus
Extra funds or free bets offered by casinos and sportsbooks. Always check wagering requirements and expiry dates.
Cash-out
An option at some sportsbooks that lets you settle a bet early for a guaranteed amount, instead of waiting for the final result.
Chasing losses
Increasing your bet size or frequency after losing, trying to “win it back”. One of the fastest ways to burn a bankroll.

D–H

Decimal odds
The most common odds format in Canada. Shows the total return per dollar staked, including your original bet.
Edge
The long-term advantage either the house or the bettor has. Casinos always have a built-in edge on their games.
Expected value (EV)
A calculation of how profitable a bet would be if you could place it many times. Most casual bets have negative EV.
Handle
The total amount of money wagered on a game, market or event at a sportsbook.
House edge
The mathematical advantage the casino has over players, expressed as a percentage of each bet.

I–P

In-play betting
Also called live betting. Placing bets while a game is already in progress, with odds that move in real time.
Line
The odds or point spread offered on a particular side or total in a game.
Moneyline
A straight bet on which team or player will win the game, with no point spread involved.
Parlay
A single bet that combines multiple selections. All legs must win for the parlay to cash; payouts are higher but so is the risk.
Payout
The total amount you receive when a bet wins – your original stake plus any profit.

R–Z

Return to player (RTP)
A percentage that indicates how much a casino game is expected to pay back to players over the long run.
Stake
The amount of money you put on a single bet or spin.
Totals (over/under)
A bet on whether the combined score in a game will be higher or lower than the line set by the sportsbook.
Variance
How “swingy” a game or betting strategy is. High-variance games have bigger upswings and downswings.
Wagering requirements
Rules that tell you how many times you must bet a bonus (and sometimes your deposit) before you can withdraw.
