How it works

Every clock has hidden patterns. The game is spotting them before they pass.

1

Catch a math minute

When the time forms a pattern — a repdigit, a run like 12:34, a palindrome — the SEND button lights up.

2

Send it to friends

Fire it off to up to 5 friends from your contacts. They have until the clock ticks over to acknowledge.

3

Score together

Every friend who taps back in time earns a point — and you earn two. Climb a leaderboard of people you actually know.
