Bulldoku is a free browser logic puzzle in the same family as LinkedIn Queens, Meowdoku, and Sudoku — with a soft bulldog theme.
Rules:
Place exactly one pup in every colored region, every row, and every column. Pups can’t touch — even diagonally. Mark impossible cells with crosses, then place only when logic forces a single option. No guessing.
