Casino pages can pack a lot of meaning into a few short labels. These are the terms worth slowing down for, especially when an offer sounds generous.
Game terms
- RTP (return to player): A long-run average across many plays. It does not tell you what one session will return.
- Volatility: A way to describe how uneven the prizes may be. A high-volatility game may have larger but rarer wins.
- Payline or ways to win: The symbol patterns the game counts. Open the paytable; the rules differ between games.
Bonus terms
- Wagering requirement: The total value of qualifying bets needed before bonus-related funds can be withdrawn. Check whether it applies to the bonus, the deposit, or both.
- Game contribution: Some offers count bets on certain games differently toward a wagering requirement.
- Expiry and maximum stake: An offer may have a deadline or a cap on each bet. Read those limits before accepting it.
One habit that helps
If the short version of an offer leaves a question unanswered, open the full terms. The details that matter are often in the limits: which games count, when the offer expires, and when money can actually be withdrawn.

Terms beyond the slot screen
- House edge: the operator’s mathematical advantage in a house-banked game over many bets. It does not predict the result of one spin or hand.
- Stake: the amount risked on a bet. Ten €1 bets mean €10 staked in total, even if some returned winnings.
- Decimal odds: a sportsbook price that includes the returned stake in a winning payout. €10 at 2.50 means €25 total return if the bet wins, not €25 profit.
- Cash-out: an offer to settle a sports bet early, or an action to end a crash-game bet before the crash. The two products use the same words but different mechanics; neither guarantees an accepted payout.
- Multiplier: in a crash game, a number applied to the stake if cash-out succeeds. €2 at 1.50× returns €3 total. If the game crashes first, the €2 stake is lost.
- Void bet: a sports bet settled as though it did not win or lose, often with the stake returned under the operator’s rules. Do not assume every abandoned match is treated the same way.
Which guide should you open next?
For table games, see live dealers. For fast multiplier games, see crash games. For odds and bet slips, see sportsbooks. If the term concerns a promotion, compare it with the full bonus-terms guide. Definitions explain a rule; they do not make a bet safe or profitable.
