Terms of Use

The short version: the games and articles are free to use for fun and learning. They aren't financial, betting or professional advice, and nothing here involves real money.

Using the site

By using themathbehindeverything.com or the Improbable app, you agree to these terms. If you don't agree, please don't use them. You can play the games and read the articles for free and without an account. Please don't try to break, overload or scrape the site, cheat the leaderboards, or use it for anything illegal.

For entertainment and education

The odds, statistics and explanations here are worked out carefully from published sources, but they're simplified models of the real world and can contain mistakes. Don't rely on them for gambling, investing, medical, legal or other important decisions. Nothing here is a recommendation to bet.

Games, leaderboards and coins

The games are games of chance played for fun. There are no cash prizes, and nothing here can be bet or won for real money. Coins, skins and other items in Improbable have no cash value, can't be sold or exchanged, and may change as the game changes. Leaderboard names are picked from an approved word list. We may remove scores or names that come from cheating or abuse.

The games, leaderboards and features can change or end at any time.

The site and app are for a general audience. Email signups and the app's online features are for people 13 and older.

The videos, articles, games, artwork and code are owned by The Math Behind Everything. You're welcome to share links and screenshots, and to quote the articles with a link back. Please don't copy whole games or articles, or present them as your own. Third-party names and trademarks, such as games and brands mentioned in a video, belong to their owners and are used only to describe what the math is about. This site isn't affiliated with or endorsed by them.

Ads and links

The site and app show ads from Google, and some pages link to other sites. We don't control those ads or sites and aren't responsible for them. See the privacy policy for how ads and analytics use data.
