The three numbers every player should know before depositing: what a session costs in expectation, what a wagering requirement really demands, and what rakeback is actually worth. All math runs on the same expected-value formulas the casinos use — just pointed in your direction.
Expected cost is the long-run average: total wagered × house edge. Volatility means any single session lands far above or below it — find each slot's exact RTP in the database.
A $100 bonus at 40× means wagering $4,000 before withdrawal. Grinding it on a high-RTP, low-volatility slot minimises the expected cost of clearing it.
Rakeback rates vary by casino, VIP level and program — check yours in the casino's rewards page and enter it above. Rakeback softens the house edge; it never flips it positive.
Real bonus value = bonus − expected cost of clearing it. Weighting below 100% inflates the effective wagering (slots usually 100%, tables often 10%). A max-cashout clause caps the upside — read the terms in our wagering guide.
All results are long-run expected values; short-term results vary wildly with volatility. 18+ · Play responsibly.
