1. What is a Casino Bonus Wagering Requirement (Rollover)?
Online casinos cannot simply hand out free cash with zero strings attached; otherwise, players would deposit, claim the match bonus, and immediately cash out. To protect their financial solvency, operators attach a wagering requirement (also known as a playthrough or rollover multiplier).
The wagering requirement dictates the total cumulative value of bets you must place before promotional bonus credits convert into real, unrestricted money in your withdrawal balance.
2. The Two Formulas: Non-Sticky (Bonus Only) vs. Sticky (Deposit + Bonus)
The most critical trap in iGaming bonus terms is the distinction between Bonus-Only wagering and Deposit + Bonus wagering:
Non-Sticky (Bonus Only)
Wagering multiplier applies strictly to the bonus portion. Your real deposit is used first; if you score a big win with real cash, you can forfeit the bonus and withdraw clean profits immediately.
Example: $100 deposit + $100 bonus at 35x = $3,500 total turnover.
Sticky (Deposit + Bonus)
The wagering multiplier is applied to both your deposit AND the bonus credits. This effectively doubles the total amount of money you must gamble before touching a withdrawal button!
Example: ($100 dep + $100 bonus) at 35x = $7,000 total turnover!

Frequently Asked Questions About Bonus Wagering (FAQ)
How does the casino bonus wagering calculator work?
The calculator multiplies your bonus credits (or deposit + bonus for sticky offers) by the wagering rollover multiplier (e.g., 35x) to output the exact mandatory turnover required before cashout unlocking. It also factors in average slot RTP to compute your expected statistical value.
What is the difference between a Sticky and Non-Sticky (Parachute) bonus?
A Non-Sticky (Parachute) bonus applies wagering strictly to the bonus funds; your real deposit cash is not locked, allowing you to forfeit the bonus and withdraw clean winnings at any time. A Sticky bonus ties your deposit and bonus together, requiring turnover on the combined total before any withdrawal is permitted.
What is considered a low, player-friendly wagering requirement?
Wagering requirements between 20x and 35x applied strictly to bonus funds are considered player-friendly with high mathematical cashout feasibility. Wagering terms over 45x or (Deposit + Bonus) structures dramatically increase the risk of busting.
How is Expected Value (EV) calculated for casino bonus wagering?
Expected Value is calculated with the formula: EV = Bonus Amount - (Total Turnover * House Edge). For example, a $100 bonus with 35x wagering ($3,500 turnover) played on a 96.5% RTP slot (3.5% house edge) results in an expected theoretical loss of $122.50, yielding an EV of -$22.50 without accounting for jackpot variance.
How do you calculate wagering on free spins winnings?
Wagering on free spins is calculated from the total amount won during the spins. If you win $30 from 70 free spins with a 35x wagering requirement, your mandatory turnover is $30 * 35 = $1,050.
