Pick a name

Names come from a fixed list rather than a text box. Nobody can type anything into a field that other players see, which is the simplest way to make sure nobody does.

Sign in

One tap with the passkey you already made. There is no username to remember, because there was never one to choose.

Create an account

An account does exactly one thing: it lets you prove you are you on another device, so your records follow you. Everything on this site works without one.

There is no email, no password and no username. A passkey lives on your device — your phone, your laptop, your password manager — and is unlocked the way you already unlock that device.

Date of birth — accounts are for players aged 16 and over

This is checked and then thrown away. It is never stored, and nothing about your age is kept beyond the fact that we asked.

Move to another device

A one-time code, good for ten minutes. Type it on the other device to bring your records across. Useful without an account, or on a browser that cannot do passkeys.

Delete everything

Removes your profile, your passkeys and your leaderboard entries. One button, no support ticket and no identity check — because there is no identity to check. Your side of a shared challenge stays, without your name on it, because the other player's result is theirs.
