Meowdoku — the Cat Logic Puzzle
A cat-themed cousin of Sudoku, Queens and Star Battle: place exactly one cat in every row, every column and every coloured region — and no two cats may touch, not even diagonally. Every board has one solution reachable by pure logic.
The rules in 30 seconds
- 1One cat per row
Every row holds exactly one cat — once a row has its cat, every other cell there stays empty.
- 2One cat per column
Same for columns — a placed cat blocks its whole column.
- 3One cat per colour
The board is split into coloured regions, and each region gets exactly one cat too.
- 4Cats never touch
No two cats may sit side by side or corner to corner — a cat blocks all eight cells around it. Place all of them and the board lights up.

Solving tips
Mark ✕ early
Tap a cell once for ✕ — ruling out impossible cells is faster than hunting the cat directly.
Start with small regions
A two-cell colour region halves the board instantly — place its constraints first.
Touching is the trap
Diagonal adjacency is the rule people forget — check all eight neighbours before placing.
Conflicts glow red
Clashing cats highlight immediately, so a red board means re-examine your last placement.
