Casino Terms Glossary
Bonus — is a promotional reward from a casino that gives you extra funds, free spins, or cashback, usually with wagering requirements attached. In gambling, a bonus can extend playtime, reduce variance, and boost a player’s bankroll, but the true value depends on rollover, eligible games, contribution rates, max bet, and withdrawal rules.

Understanding Bonus
In gambling, Bonus meaning refers to any incentive—cash match, free spins, or rebate—offered to encourage real-money play. The Bonus definition includes the fine print: wagering (rollover), game weighting, eligibility, expiry, max bet while clearing, and caps on winnings. This term matters because headline amounts can be misleading if playthrough is high or games contribute poorly. We teach you how to read bonus terms and, at 101RTP, you can explore honest casino and slot reviews and use our Slot Simulator and Bonus Value Score calculator to estimate realistic value before claiming and to align bonuses with your bankroll strategy.
Examples of Bonus
- Welcome bonus (e.g., 100% match up to $500 + 100 free spins): boosts new player bankroll; typical 30–40x rollover; slots 100% contribution; table games reduced.
- No-deposit bonus ($10 free or 20 spins): small starter credit; higher rollover and cashout cap; great for testing a casino.
- Reload bonus (50% every Friday): ongoing offer for existing players; lower match but frequent; watch max-bet and game weighting.
- Cashback bonus (10% of net losses): usually wager-free or low rollover; credited daily/weekly; helps smooth variance.
FAQs
What is a casino Bonus?
A casino Bonus is an incentive—extra funds, free spins, or cashback—granted to players under specific terms. The Bonus definition includes wagering requirements (rollover), eligible games, expiry dates, max-bet rules, and possible win caps. Understanding these conditions tells you the real value behind the promotion and how it fits your gambling style.
How do wagering requirements work on a Bonus?
Wagering requirements (e.g., 35x bonus) tell you how much you must bet before withdrawing. If you get $100 bonus at 35x, you need $3,500 in eligible wagers. Contribution varies by game, so slots may count 100% while many table games contribute partially or not at all. Always confirm the term’s exact formula.
Can a Bonus be withdrawn immediately?
Usually not. Most bonuses are “locked” until you meet rollover, respect max-bet limits, and avoid restricted games. Breaking rules can void winnings. Some offers are wager-free (e.g., cashback), meaning the bonus or winnings are withdrawable right away, but always confirm terms, caps on winnings, and any eligibility rules before cashing out.
Is a higher Bonus amount always better?
Not necessarily. A big headline can hide tough conditions—high playthrough, low game contribution, short expiry, or capped winnings. Compare expected value, variance, and your stake size. The best bonus aligns with your bankroll, preferred games, and session length, not just the biggest percentage match or the largest free-spins bundle.
Do all games contribute equally to a Bonus?
No. Slots usually count 100% toward rollover; blackjack, roulette, video poker, and live dealer frequently contribute less or are excluded. Check the game weighting table and RTP/volatility to decide where to play. Prioritize eligible, high-contribution games to clear the bonus efficiently and protect your bankroll from unnecessary grind.
Why should I trust Bonus meaning and terms over advertising?
The small print defines your actual experience. Bonus meaning and conditions—rollover, max bet, expiry—determine risk and time to clear. Use independent resources like 101RTP for honest casino and slot reviews that decode terms, highlight traps, and show which operators apply fair, transparent rules to promotions and player treatment.
How can I find and evaluate the best Bonus for my playstyle?
Start with your budget and preferred games, then compare rollover, weighting, and time limits. At 101RTP, our Slot Simulator and Bonus Value Score calculator help you test stakes, model outcomes, and estimate EV, so you can choose bonuses that fit your bankroll, volatility comfort, and session goals without guesswork.
