About House Edge Guide
An independent educational guide to casino game odds, house edge, variance, design, regulation and responsible play.
Who this site is for
Curious readers who want to understand how casino games work, not tips on winning.
How the guides are written
- Answer first. Each guide leads with the direct answer, then explains the why and the how.
- Practical numbers. Concrete values you can use, with ranges rather than false precision.
- Connected, not repeated. Short, focused articles link to the in-depth guide for their topic, so you can go as deep as you need.
- Dated. Every article shows when it was published.
Please note
General information only, not advice: casino games are games of chance with a built-in house edge, most players lose money over time, and nobody should gamble money they cannot afford to lose.
