## What is Haydoku?

Find the hidden animals — no timer, no pressure, just you and a quiet moment of logic.

Haydoku is a cozy animal sudoku puzzle. Little animals are hiding in colorful haystacks, and every single one of them can be found by pure reasoning. No luck, no guessing — think it through and you will always find them.

SIMPLE RULES, DEEP DEDUCTION — Each color region hides exactly one animal. — Each row and each column holds exactly one. — Animals never touch, not even diagonally. — Double-tap a haystack to reveal an animal. You have 3 hearts, and every puzzle is solvable by reasoning alone.

RELAX & UNWIND — Soft hand-drawn art, gentle sounds, no timers, no pressure. Play one puzzle to decompress, or sink into a long cozy session.

10,000+ PUZZLES — From quick 5x5 boards to deviously clever 12x12 grids, with difficulty that grows gently — always challenged, never stuck.

DAILY LOGIC PUZZLE — One fresh puzzle every day, the same for everyone. Build your streak.

HELPFUL HINTS — Stuck? A gentle nudge shows you the next logical step — teaching, not spoiling.

PLAY OFFLINE — No internet needed. Perfect for commutes, queues, and quiet evenings.

If you enjoy Star Battle or Queens-style logic puzzles, you will feel right at home — the same kind of deduction, wrapped in a cosy little farm.

Love sudoku, or just want a calm brain teaser to wind down with? Haydoku is your new cozy corner.

Find the animals. Calm your mind.
