Candy Doku

Candy Doku is a lovely grid puzzle game with cute puppy themes.
Drag puppy avatars onto colored grid squares to finish each level under three core rules: only one puppy per color block, one puppy per row & column, and one puppy inside every 3×3 zone.
Cross-marked cells are blocked and cannot hold puppies. Complete all placement targets to clear levels and unlock richer grid layouts.
