Every score on the board is earned.

Your phone sends your taps. Our server replays them with the same game and works out the score. A number typed into a phone never counts.

Each ranked attempt is built new on our server, so there is no pattern to learn by heart. Every version is tested to be equally hard.

Every ranked run is checked for timing a person can't produce. Anything flagged is held off the board until a person reviews it.

The game plays the same on an entry-level Android and the newest flagship, on any screen size, at any frame rate.

We confirm who every winner is before a prize goes out. The biggest prizes are settled in a live playoff.

Every league shows its game, prize, close time and tiebreak before you pay for a round.

• Bots, scripts, auto-clickers or modified browsers.
• More than one account, or someone else playing for you.
• Tampering with the game or its connection, or using a bug for advantage.

Runs that break these rules are voided and any prize is withheld. Every decision can be reviewed against the replay of the attempt.

Every game is tested against cheating before it opens to ranked play: by our own security engineers first, then by an independent tester before launch.
