How it's played
Fill the 9×9 grid so every row, column, and 3×3 box contains the digits 1–9 — no repeats. Watch the board: scan the row, the column, and the box, and there's only ever one digit that fits. Simple to learn, endlessly satisfying to master.
And then there's Meow Mode 🐱
A whole second logic game behind one switch. The board is split into coloured territories, and every territory needs exactly one cat — but cats demand personal space: never the same row or column, never touching, not even diagonally. Three hearts, no guessing; every cat can be deduced.
Everything you'd want, nothing you wouldn't
A second game on the same shelf: place one cat per coloured territory — never sharing a row or column, never touching. Its own levels, its own history.
