Bonus Comparison Tool
Two offers, one answer. Enter the terms of any two casino bonuses and see which is genuinely better value once wagering, game contribution, RTP and max-cashout caps are taken into account — not just which has the bigger headline number.
| Metric | Offer A | Offer B |

EV is a long-run average, not a prediction for one session — real results vary widely. A positive EV means an offer is, on average, worth claiming; it never guarantees a win. Always read the full bonus terms on the operator's site. Play responsibly →
Why the bigger bonus often loses
Casinos compete on headline numbers because big percentages sell. But a bonus is only worth what survives its wagering requirement. Two things decide that: how much you have to bet to clear it (wagering × bonus, adjusted for game contribution), and how much of the bonus the house edge eats along the way (driven by RTP).
A "200% up to $2,000" offer with 60× wagering, 20% table-game contribution and a 5× cashout cap can be mathematically worse than a plain "100% up to $500" with 25× wagering on 100%-contribution slots. This tool runs both through the same expected-value calculation so the marketing washes out and the real number is left standing.

Bonus comparison FAQ
How do you compare two casino bonuses fairly?
The only fair comparison is expected value (EV): the bonus amount minus the expected loss from wagering it through. A bigger headline bonus with heavy wagering can be worth less than a smaller offer with easy terms. This tool calculates the EV of each offer using the same maths — match, wagering, game contribution, RTP and any max-cashout cap — so you're comparing like with like.
What makes one bonus better than another?
Lower wagering, higher game contribution, higher RTP, a generous (or no) max-cashout cap, and a larger effective bonus all push EV up. A 200% bonus with 60x wagering and a 5x cashout cap is often worse than a 100% bonus with 25x wagering and no cap.
Does the bigger bonus always win?
No. The headline percentage is marketing. What matters is how much of that bonus survives the wagering requirement and any cap on winnings. This tool exists precisely to catch offers that look huge but are mathematically poor.
What does the EV figure mean?
Expected value is the average outcome if you claimed the bonus and played through the wagering many times over. Positive EV means the offer is, on average, worth claiming; negative EV means the expected cost of clearing it outweighs the bonus. It's a long-run average, not a guarantee for any single session.
