Wagering requirements are the most important factor in determining the real value of a casino bonus. This guide explains exactly how they work and how to calculate their impact on your expected returns.
Wagering requirements specify how many times you must bet the bonus amount (and sometimes the deposit) before you can withdraw winnings. A 35x wagering requirement on a 100 bonus means you must place 3,500 in total bets before cashing out.
Not all games contribute equally to wagering. Typically: Slots contribute 100%, table games 10-20%, and live dealer games 0-10%. Always check the specific terms for game weighting.
The formula: Expected Loss = Total Wager x House Edge. For a 100 bonus at 35x on slots (3% house edge): Expected Loss = 3,500 x 0.03 = 105. This means the expected value of the bonus is negative in this case.
