Fundoku: Logic Puzzle Game

Solve colorful logic puzzles by finding one hidden jewel in every row, column, and region. Jewels never touch, even diagonally. Every color hides a jewel. Can you find them all? Fundoku is a colorful logic puzzle game about finding hidden jewels through careful deduction. Study each grid, connect the clues, and mark the spaces you can rule out. Simple rules lead to satisfying puzzles as the boards grow. SIMPLE RULES, ONE GOAL Each row, each column, and each colored region contains exactly one jewel. Jewels never touch, even diagonally. Use these rules together to uncover every hidden jewel and complete the level. EASY TO LEARN, ROOM TO THINK Tap a square once to mark it as empty. Drag across several squares to mark them together. Double-tap when you are ready to reveal a jewel. You have three hearts per level, and each incorrect reveal costs one heart. 500 LEVELS TO EXPLORE Start with compact 4x4 grids and progress to boards as large as 11x11. Unlock levels as you solve them, save your progress, and return to unlocked puzzles through the level picker. In-game rules and a first-level tutorial help you get started.
