This policy explains how our calculators work and what you should expect from them.
Estimates only
Every calculator shows an estimate based on the inputs you enter and a stated house edge. Real results vary, and short sessions can differ widely from the average.
How results are worked out
Our tools use simple, open formulas. You can read the steps on the methodology page.
Your data
Calculators run in your browser. The numbers you enter are not sent to our server or stored by us. See our privacy policy for details.
Accuracy and updates
We test each tool with worked examples before it goes live. Game rules and pay tables differ between casinos, so always check the rules of the game you play.
Reporting a problem
If a result looks wrong, email Anabella@houseedgecalculator.com with the inputs you used. We will review it and fix confirmed errors.
