## What is StarDoku?

Cozy logic. Charming critters.

StarDoku: Critter Logic is a colorful deduction puzzle inspired by the classic one-star-per-row challenge. Place one critter in every row, column, and colored region—but critters can’t touch, even diagonally. Every puzzle is designed to yield to logic, so careful deduction beats guessing.

LEARN BY PLAYING
An interactive tutorial walks you through the rules on a real practice board. Start with simple deductions, follow the chain, and build confidence as the puzzles become more challenging.

MAKE IT YOURS
Choose River Otter or Highland Cow as your starter mascot, then earn and collect more skins. Each critter brings its own look, animations, sounds, and color palette.

PLAY YOUR WAY
• Adjustable double-tap timing
• Color-vision palettes for protanopia, deuteranopia, and tritanopia
• A monochrome high-contrast palette
• Independent music, sound-effect, and haptic controls
• Optional hints, critter reveals, and one Oops recovery per level

CHASE YOUR BEST
Build combos, improve your score and solve time, protect perfect-win streaks, and review personal records stored locally on your device. No account is required.

ENJOY 400 PUZZLES
Follow a carefully paced difficulty curve, from relaxing introductions to deeper, multi-step deductions.

StarDoku is free to play. Optional rewarded ads provide bonuses. An optional purchase removes between-level ads while leaving rewarded bonuses available whenever you choose them.
