## What is Goodoku?

If you love Queens, Sudoku, and other daily logic puzzles, try this cozier take.

Place one goo in every row, column, and color region — and keep the goos from touching, not even diagonally. That's the whole rule, and it gets delightfully tricky.

HOW TO PLAY
• Tap a cell to cross it out
• Double-tap to place or remove a goo
• Every puzzle starts with one goo placed, showing you how deduction works
• There's exactly one solution — pure logic, no guessing

PUZZLES FOR EVERY MOOD
• Climb from quick 5x5 boards to full 10x10 challenges
• A new Daily Puzzle every day — keep your streak going
• Endless 10x10 puzzles when one board isn't enough
• Optional hints if you get stuck

COZY BY DESIGN
• Soft pastel boards and glossy goo blobs
• No account, no sign-up — and no data collected
• Fully playable offline (except ads)
• Progress stays on your device
