Bonus Mathematics
Understanding the math behind bonuses helps you play smarter. Assume a welcome bonus of 100% up to $500 with a 30x wagering requirement on the bonus amount.
Important: Wagering requirements apply only to the bonus, not the deposit, unless stated otherwise.
If you deposit $200, you receive $200 bonus. Total balance: $400. Wagering requirement = $200 × 30 = $6,000.
Now factor in game contribution. Slots usually contribute 100%, table games only 10%. If you play only slots, you need to wager $6,000. If you mix, say 50% slots (100% contribution) and 50% blackjack (10% contribution), the effective wagering amount increases:
Effective wagering = (0.5 × $6,000 / 1.00) + (0.5 × $6,000 / 0.10) = $3,000 + $30,000 = $33,000.
That’s a huge difference. Always check game contribution percentages in the bonus terms.
Expected value (EV) of the bonus: EV = bonus amount – (wagering × house edge). Assuming average slot RTP 96% (house edge 4%), for $200 bonus and $6,000 wagering: EV = $200 – ($6,000 × 0.04) = $200 – $240 = –$40. Negative EV means the bonus is not profitable on average. However, with high RTP slots (99%) the house edge is 1%: EV = $200 – ($6,000 × 0.01) = $200 – $60 = $140. So choose games with high RTP.

Worth Knowing
Game categories with the best RTP include classic slots, video slots, and live dealer baccarat (around 98–99%). Avoid progressive jackpot slots, which often have RTP below 90% because the jackpot contribution lowers the base payout. Also, keno and some scratch cards have RTP as low as 75–85%.
Always read the specific game’s paytable and rules. High RTP does not guarantee winning, but it improves your mathematical edge over time. Combine with bonus math to make informed decisions.
