About
New to number puzzles? That is perfectly fine.
Cheondoku is sudoku that deepens slowly, without pressure.
◆ 6x6 Warm-Up — Free
Start small and easy. Ideal for anyone picking up sudoku for the first time.
◆ Zen, Sun, Moon — Three Paths (1,000 puzzles each)
· Zen — Stillness. Before sleep, during meditation.
· Sun — Vitality. The first puzzle of the morning, at a cafe.
· Moon — Quiet. A calm night when rest won't come.
Three palettes, three depths. A 3,000-puzzle journey that grows with you.
◆ Difficulty for Everyone
From beginner to easy. Hints are there when you need them, and mistakes are part of the process.
◆ Quiet Design
No flashy effects — just an interface that lets your thoughts settle.
Ten minutes a day to clear your mind.
[How It Works]
· Free to download — the 1,000 Zen 9x9 puzzles and the 6x6 warm-up are free to play, with ads.
· One purchase opens Sun and Moon — 2,000 more puzzles, all 3,000 in hand — and removes every ad.
· There is a single in-app purchase. A one-time payment, not a subscription.
