Chessoku is a logic puzzle game built around chess piece movements. Place knights, bishops, rooks, queens, and kings on a mini chess board by analyzing threat counts and deducing where each piece belongs.
HOW IT WORKS
Every cell on the board shows how many chess pieces can attack it. Using these numbers and your knowledge of how each piece moves, figure out the correct placement. No guessing required — every puzzle is solvable through pure logic.
JOURNEY MODE
Progress through themed level packs, starting with beginner-friendly puzzles and advancing to expert-level challenges. Earn coins, XP, and collectible cards as you complete each pack. Unlock new packs featuring specific piece combinations for focused training.
