How to get on the board

Scoring

A 4 × 4 grid uses 1–4, a 6 × 6 uses 1–6 and a 9 × 9 uses 1–9. No digit repeats in a row or a column.
+ means the cage adds up to the target and × means it multiplies to it. − and ÷ cages always have two cells: take the smaller digit from (or divide it into) the larger one.

What qualifies

Wins only, ranked by time. A lost game is a lesson, not an entry.

Your scores are saved in this browser the moment a game ends. Set a nickname in your profile and qualifying results post to the global board as well — nickname only, no email, no password, no newsletter.

House target and par are set by us from the game’s scoring. They are something to beat, not someone.
