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.

Turn turtles into stepping stones and get the bunny to the carrots! ZeroRoad is a number puzzle set in a peaceful pond. The number on each turtle's shell is how far it can swim. Every square it moves lowers the number by 1, and at exactly 0 it tucks into its shell and becomes a stepping stone. Link the bunny's island to the carrot island and the stage is clear! 【How to Play】 - Drag a turtle to swim. Each square lowers its number by 1 - Let go at 0 and it tucks in to become a stepping stone - Lily pads are ready-made stones. Turtles can dive right under them - Tap a placed turtle to send it back home - Connect the bunny to the carrots to clear the stage 【Key Rules】 - Rocks and islands can't be entered - Turtles can pass over lily pads and other turtles. That square still costs 1 - A turtle can't reach farther than its number. Which turtle, in what order, to where? That's the puzzle 【2,000 Stages】 A short animated guide shows the rules, and the first 7 stages are a hands-on tutorial. Ponds grow as you progress, with lily pads and rocks shaping the way. Difficulty rises and falls in waves, so a tough stage is followed by a breather. - No lives, no timers, no stamina - Progress is saved, so you pick up where you left off 【Stuck? Use a Hint】 Pick any turtle and use a hint on it: it glows gold, swims to its right spot, and locks in place. You start with 5 hints; watch an ad to get more. 【Features】 - Simple drag and tap controls in portrait mode - A cozy low-poly 3D pond with an adorable bunny and turtles - Separate volume sliders for music and sound effects - Reset a stage anytime 【Perfect For】 - Fans of number puzzles, logic puzzles and brain teasers - Players who love thinking games like Sudoku or Sokoban - Anyone who wants a relaxing brain workout with cute animals - Commutes, queues and short breaks Count the turtles down to zero and build the road. 2,000 stages: can you get the bunny home?
