Otterdoku: Cozy Logic Puzzle

🦦 Welcome to Otter Springs — a cozy star battle logic puzzle. Same rules you know from Queens and Two Not Touch, wrapped in a quiet watercolor pond.

Place one otter in every row, every column, and every colored pool — and never
let two otters touch. No lives. No timers. Mark, test and undo as much as you
like.

🌿 IF YOU LOVE SUDOKU, YOU ALREADY KNOW HOW TO PLAY
Otterdoku sits in the same family as Sudoku, Minesweeper, nonograms and classic logic grid puzzles. If you enjoy daily logic puzzles or the star battle format, you'll feel at home within one spring.

✨ SIMPLE TO LEARN, LOVELY TO MASTER
- One otter per row
- One otter per column
- One otter per colored pool
- No two otters may touch — not even diagonally
That's the whole rule. From there, each spring unfolds into a satisfying little
deduction.

🍃 FREEDOM TO EXPERIMENT
Leaf Notes let you mark your thinking, just like pencil marks on paper. Try
something, undo it, try again. There are no hearts to lose and nothing to
punish you for exploring — this is a cozy logic puzzle, not a test.

☕ MADE FOR RELAXING
No countdowns. No lives. No pressure. Otterdoku is built for a peaceful few
minutes — on a coffee break, before bed, or whenever you need to unwind. Play
offline anytime; no wifi needed.
