About e.casino
We explain how casino games really work, with math you can check and labs you can play for free, so that every adult who gambles does it with open eyes.
What we are — and what we are not
e.casino is an independent educational publication. We publish in-depth guides to casino games, probability and gambling psychology; we build free interactive labs and calculators; and we point people to free, confidential help when gambling stops being fun.
- We are not a casino. There is no real-money gambling on e.casino, no deposits and no prizes for gambling outcomes. Virtual chips in our labs have no value.
- We are not an affiliate. We do not link to casinos or sportsbooks for commission, and we never rank or review operators.
- We are reader- and ad-supported. Revenue comes from display advertising, clearly labeled sponsorships and reader contributions.
Why “e”?
Partly because e stands for edge — the house edge is the center of everything we teach — and for education. But mostly because of Euler's number, e ≈ 2.71828. Take any one-in-N chance and try it N times, and you'll miss every single time about 1/e ≈ 36.8% of the time. Bet one roulette number for 37 spins and there's roughly a 36% chance it never comes up. Intuition says “it's bound to hit eventually”; e says otherwise. That gap between intuition and math is exactly what we exist to close.
How we work
Every guide is written for clarity and reviewed for accuracy. Numbers are derived from first principles or standard published game math and cross-checked in our own simulators. When we make a mistake, we fix it and note the correction. Read the details in our editorial policy.
The team
e.casino is produced by a small independent editorial team of writers, developers and reviewers with backgrounds in mathematics, software and digital publishing. We're growing — see careers if you'd like to contribute.
