ChikiDoku: Queens Logic Puzzle

A cute Queens logic puzzle with live 1v1 duels and 1,000 levels of brain teasers.

ChikiDoku is a Queens logic puzzle, also known as Star Battle: a brain game like Sudoku, with adorable chicks on a painted road of a thousand levels. The rules fit in one breath: one chick in every row, every column and every coloured nest, and no two chicks may touch, not even at the corners.

Every puzzle has exactly one solution and is solved by pure logic. No guessing, no luck: just that brilliant "aha!" when the last chick hops into place.

HELPERS THAT TEACH YOU THE LOGIC
• Mama Hen shows the next logical step and tells you why, so you learn Queens and Star Battle puzzles as you play.
• Digger the puppy digs up squares where no chick can be.
• Papa Rooster places one chick for you.
• You hold a few of each. Win more by playing, or get them in the shop. In a duel, each helper works at most twice a match.

• A wrong chick breaks one of your hearts, so think before you hatch.
