A free logic puzzle and brain game for iPhone and Android

Toucandoku is a sudoku-style puzzle game where every toucan needs the perfect perch. Place one toucan in every row, every column and every colored region, and never let two touch. Three rules, ten seconds to learn, and pure logic all the way: no guessing, no luck. A relaxing brain teaser for your coffee break.

How to play

How to play Toucandoku: three simple rules

One toucan in every row and every column.
One toucan in every colored region.
No two toucans may touch — not side by side, and not corner to corner.

Tap a square once to mark it with an X, and tap again to place a toucan. Rule out squares, follow what has to be true, and the logic puzzle solves itself. If you enjoy sudoku, nonograms, star battle or other logic games, this brain teaser will feel right at home.
