Enter the terms of a bonus and run 2,500 simulated attempts to clear the wagering. The tool reports how often the balance is lost, how often the wagering is completed, and what is left when it is.
Each run plays spins at your chosen stake against the game RTP. Turnover accumulates at the game contribution rate you set. A run ends when the wagering target is met, when the balance can no longer cover a spin, or when the expiry window closes.
The expiry window is converted to spins using an assumption of 500 spins per day. That figure is shown on the page so you can judge whether it matches how you play.
The Malta and Nordic presets use the median wagering multiple recorded for tracked operators in those markets in the wagering requirement benchmark. The UK preset uses 10x, the regulatory cap. No preset refers to a named operator or a live offer.
Bust rate is the share of runs that lost the whole balance before clearing the wagering. Completion rate is the share that cleared it. Median finishing balance covers completed runs only, so it is the amount a successful attempt was left holding.
This is a simulation against published mathematics, not a record of real play. Volatility is approximated with a simple payout model and no real game is reproduced exactly. Results are estimates from 2,500 random runs and will move slightly each time you run them. No simulation predicts an individual session.

Turnover multiplies exposure to the house edge. A 35x wagering requirement on a 100 euro bonus means 3,500 euro of turnover, and at a 4 percent house edge the expected cost of that turnover is 140 euro, more than the bonus itself.
Yes. On a matched offer it doubles the turnover required, which roughly doubles the expected cost of clearing the bonus and sharply raises the bust rate.
No. The figures describe a distribution across thousands of simulated runs. A single attempt can end anywhere in that distribution.
