Create your account

No email needed. Use your real name — that is what you will sign in with, so there is no username to remember. You will get your own Mastermind ID and start at a 1200 rating; your first rated game at the café is what starts moving it.

Played at the café before? Sign in with your old username instead — signing up again starts a second account at 1200 and leaves your games behind.

Use your real name — this is how you sign in.

We only use this for age groups at tournaments.

At least 8 characters.

For the café records and for age and gender sections at tournaments.
