Sports Rules

New to a sport? Don't read the rulebook — play with it. Drag the players, make the call, and the rules explain themselves.

Offside Trainer NEW

These trainers are made for people who have never watched a full game: kids, new fans, or anyone joining friends for a match day. Each one starts with a single-sentence version of the rule, lets you experiment on an interactive field, and then puts you in the referee's shoes with a short quiz.

Everything runs in your browser — nothing to install, no account, and it works on phones and tablets. Wrong answers never cost you anything: every call comes with a friendly explanation of why, so you learn by trying.

Frequently asked questions

Who are these sports rules trainers for?
Complete beginners. If you have never understood offside, downs or innings, these tools explain them visually in a few minutes — no prior knowledge needed. They are also handy for parents coaching kids' teams for the first time.
Do I need to install anything or create an account?
No. Everything runs directly in your web browser on desktop, tablet and mobile. There is no download, no sign-up and no personal data required.
Are the rules simplified or official?
The trainers teach the official core of each rule, but start from a one-sentence simplified version so beginners are not overwhelmed. Rare edge cases handled by professional referees are left out on purpose — the goal is to enjoy watching and playing, not to pass a referee exam.
