Simple rules, surprisingly deep puzzles.
Piyodoko is a cozy logic puzzle where you place cute chicks on a colorful grid. Every puzzle is built to be solved by logic alone: no guessing, just that satisfying "aha!" moment.
THREE SIMPLE RULES
- One chick in every row and every column
- One chick in every color area
- Chicks never touch each other, not even diagonally
Tap to mark a cell with an X, double-tap to place a chick. A short tutorial gets you started in a minute.
If you enjoy star battle puzzles, you will feel right at home.
