About this site

A collection of short puzzles that run straight in your browser. No install, no account, no sign-in.

Daily challenge

A new board opens every midnight, Korea time. That day everyone starts from the same board, so it comes down to reading the puzzle rather than luck. Rankings reset when the next board opens.

How scores are kept

We do not ask you to sign in. Your browser generates a random identifier and scores are grouped by that. You are only asked for a nickname when you set a score good enough for the board.

That means clearing your browser data or switching devices breaks the link. Your personal best is also stored locally, so it stays visible whether or not you post it.
