Chessdoku
Puzzle
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
1,500 chess-logic puzzles that never need a guess, plus a fresh daily challenge to keep your streak alive. Free to start — one purchase unlocks everything.
Place the given chess pieces so every row and column holds exactly one piece — and no piece threatens another. That's Chessdoku: the discipline of Sudoku, the geometry of chess.
NO GUESSING, EVER
Every puzzle is generated by a built-in deduction engine and verified solvable by pure logic. Stuck? The hint doesn't just drop a piece — it explains the deduction you could have made.
FIVE WAYS TO PLAY
- Classic — open square boards, from a gentle 4×4 to the deep end
- Panorama — wide boards that bend your instincts
- Fortress — frozen pawn walls cut the lines, so extra pieces fit
- Command — you place the pawns, and your pieces need them
- Torus — borderless boards where attacks wrap around the edges
300 levels in each mode — 1,500 puzzles in all.
EVERY DAY, ONE PUZZLE
A daily challenge seeded from the date, identical for every player on Earth. Keep your streak alive and share your result, spoiler-free.
THINK WITH YOUR HANDS
Cross off dead squares with the X tool, pencil-mark individual piece options Sudoku-style, long-press any piece to see exactly what it attacks, and let the app prove it the moment a position becomes unwinnable.
FREE TO PLAY
The daily challenge, the tutorial, and a generous run of free levels — including the first 100 in Classic — are free to everyone. One optional purchase unlocks all 1,500 levels and every Quick Play preset — no subscription, ever.
YOURS, OFFLINE
No account. No ads. No tracking. Puzzles are generated on your device and your progress never leaves it. Seventeen handcrafted board themes, including a colorblind-friendly high-contrast set.
