Common questions
Do I need an account to use these?
No. Every tool runs entirely in your browser. Nothing you type is sent to us, and the trackers keep their data on your own device.
Which tool should I use before claiming a bonus?
Start with the true bonus value calculator — it nets the headline offer against wagering, game weighting and the maximum cashout, which is where most offers lose their appeal. Use the wagering calculator afterwards if you want the exact turnover figure.
What is the difference between the RTP calculator and house edge comparison?
The RTP calculator answers "what should I expect back from this specific game at this stake". The house edge comparison answers "which category of game should I be playing at all". Use the comparison first, the calculator second.
Are these tools a way to beat the casino?
No, and anything claiming otherwise is lying to you. Every game here has a built-in edge for the house. These tools help you understand what that edge costs, choose the cheaper games, and notice sooner when a session is going badly.
