Multiplayer calendar puzzle — the Live Arena

Play the calendar puzzle against real people, live. Every five minutes a new round starts and every player in the world gets the same board and the same eight pieces at the same second. Fastest solve tops the leaderboard. It is free, it runs in the browser, and it does not need an account.

Race your friends, or the whole world

Because the round is identical for everyone, times are directly comparable — you are not comparing solves of different boards on different days. Send friends the link and you are all in the same round; leave it open and you are racing whoever else is online.

Watch how everyone else solved it

When the round ends you can replay it move by move, yours and everyone else's, which is the fastest way to find out why the top times were faster.

How a round works

A round lasts five minutes. Open the arena, wait for the countdown, and the board appears for everyone at once. Cover the board so only the round's month and day are left uncovered. Finish and your time posts to the live leaderboard immediately; the next round starts straight after.
