EV calculator

Choose a bonus, its playthrough and the redemption minimum, then see how 10,000 simulated sessions end. Each game uses one fixed house edge, so use the result to compare offer terms, not to predict a session. This free tool comes from Beat the Spin, the Chrome extension for daily bonus timers and reminders.

How to read the result

This is a simplified house-edge model, not a prediction of a real session. It uses equal-sized wins and losses and does not capture slot volatility, jackpots, or bonus rounds. Results depend on the assumptions you choose.

Each trial stops at zero balance or completed playthrough. Expected redemption is the average amount left after playthrough, counting any balance under the redemption minimum as zero, before subtracting your starting bankroll. Above starting bankroll is the share of runs that end at or over the redemption minimum with more than you started with, so with a minimum above your bankroll it counts only runs that reach the minimum. No redeemable outcome is the share that end at zero or under the minimum.

Check the operator's current rules and eligibility terms before relying on an actual offer.
