How it works: Expected loss = Total Effective Wagering x (1 - RTP). Expected Value = Bonus Amount - Expected Loss. A positive EV means the bonus is statistically worth claiming.

How to Read Your Results
♠ What Are Wagering Requirements?
Wagering requirements tell you how many times you must bet the bonus (or deposit + bonus) before you can withdraw any winnings. A $100 bonus with 40x wagering means you need to place $4,000 in total bets. The higher the multiplier, the harder it is to profit from the bonus.
♥ Why Game Contribution Matters
Not every game counts equally toward clearing your wagering. Slots typically contribute 100%, but blackjack might only contribute 10%. If you play a game with 10% contribution, your effective wagering requirement is 10x higher — turning a 40x requirement into 400x in practice.
♦ What Expected Value Means
Expected Value (EV) is a mathematical concept that estimates the average outcome over many repetitions. A positive EV bonus means you are statistically likely to profit after clearing wagering. A negative EV bonus means you will lose money on average — though variance means you can still get lucky on any given attempt.
