Pixelry Sudoku
Read full descriptionHide full description
It's the kind of Sudoku where you look up and an hour has quietly gone. Tap a color, tap a cell - a cube clicks into place, a chime drifts into the ambient music underneath, and the grid breathes back. Color logic instead of numbers, made for the quiet moments between things. A fresh Daily Challenge arrives every morning, drawn from a library of 20,000 hand-graded puzzles. Build a streak, then come back tomorrow. No ads. No accounts. No tracking. No subscriptions. Everything runs offline, forever. - A meditative Sudoku, designed for slowness. Soft colors, slow movements, ambient music drifting underneath - everything tuned to dissolve the clock rather than chase it. - Tactile haptics on every interaction. The palette taps, cubes snap into place, completions ripple, conflicts pulse, removals click. The board feels physical in your hand. - Color logic, not numbers. Nine colors, with an optional symbol overlay for colorblind play. - Four difficulty tiers - Casual, Medium, Hard, Master - plus a gentle Mini tutorial to learn the rules. Every puzzle is solvable with classic technique alone. No forcing chains. No guessing. - Two-tier hints: a soft nudge that points to the right area, or a hard hint that fills a single cell. Always free, never paywalled. - Six chrome themes shared with the Pixelry family - Obsidian, Bone, Dusk, Moss, Fjord, Ember. Pick the mood by spinning the cube on the home screen. - Four puzzle palettes - Balanced is free; Vibrant, Pastel, and Dusk are part of the optional premium unlock. - Ambient dub-electronica with warm tape-echo textures. Headphones recommended. - Pencil marks (annotations) that auto-clear when you place a peer. - Soft conflict highlighting - the game points out duplicates but never blocks you. The puzzle trusts you. - Daily Challenge streak, best times per tier, full local stats. Eleven languages, full VoiceOver and Dynamic Type support. - Offline by default. The whole game travels with you - long flights, subway tunnels, mountain cabins, anywhere with no signal. - Local progress, local stats, local everything. Your data never leaves the device. Optional one-time premium unlock removes the puzzle limits, opens the full Daily Challenge archive, and adds the Vibrant, Pastel, and Dusk palettes plus all cube styles. No subscriptions. No paywalls mid-puzzle. Pixelry Sudoku is part of the Pixelry family - a small, independent set of meditative puzzle apps designed to be returned to, not optimized around. Made by a tiny team with plenty of headphones, coffee, and a love for carefully crafted puzzle details.
