Board 1 ledger
One tap a floor, about a minute a tower: the plainest test of timing there is, drawn in ink.
Play a round to see where you stand against the Junior, Expert and Pro levels.
Every finished game counts. The board keeps your best score per variant; the rest stays in your history.
Your scores are saved in this browser the moment a game ends. Invite a colleague from your profile and the two of you see each other’s bests — nobody else does. Nickname only, no email, no password.
Pro, Expert and Junior are skill levels we set from the game’s scoring. They are something to beat, not someone.
