Turtledoku: Logic Puzzle

One turtle per pond.

Turtledoku is a calm logic puzzle with one simple rule: place one turtle in every coloured pond, every row and every column. Turtles like their space, so no two may touch, not even diagonally. Find the answer with pure reasoning, then watch your turtles wiggle with joy.

PURE LOGIC, NO GUESSING
• Every puzzle has exactly one solution, and you can reach it step by step without guessing.
• Tap once to mark a square with ×, twice to place a turtle. Drag to mark many squares at once.
• Auto-cross marks the squares a new turtle rules out, so you can focus on thinking.

HINTS THAT TEACH
• Stuck? A hint does more than show the answer. It highlights the squares and tells you why, for example: "This pond has only one free square left."
• Learn the tricks one by one and solve bigger boards on your own.

200 LEVELS AND A DAILY PUZZLE
• Boards grow from 5×5 to 10×10 as you get better.
• A new daily puzzle every day. Keep your streak going.
• After all 200 levels, bonus puzzles keep coming.

MAKE IT YOURS
• Earn shells and unlock six shell styles, from Mint to Starry.
• Play by the Pond, on the Beach or by Moonlight.
• Colour-blind friendly: turn on pond patterns to tell ponds apart without colour.

RELAXED BY DESIGN
• Three hearts per puzzle and no time limit.
• Plays offline. Available in English, Türkçe, Español, Português and Deutsch.

Turtledoku is free to play and shows ads. Ads never interrupt a puzzle: optional reward ads give you an extra hint, an extra heart or double shells.
