Sudoku on a cube, with hints !
Kropki 3D Sudoku is a calm, focused logic puzzle game built around a three-dimensional cube: six faces, each a 3×3 grid. On every face, the digits 1 through 9 appear exactly once—like nine mini Sudoku “boxes” wrapped around a solid shape. Between adjacent cells (including pairs that meet around an edge of the cube), Kropki-style clues tighten the search: one mark means the two values are consecutive (difference of 1); another means one value is double the other. Givens stay fixed; your job is to deduce the unique solution without breaking the rules.
Play your way
• Campaign — A curated 26-level ladder from gentler teaching puzzles through hard and expert challenges, taking from seconds to minutes and ending in a bonus checkpoint. Levels unlock in order; you can replay cleared stages anytime to improve your time.
• Daily challenge — A new puzzle each day. Build a streak, chase your best time, and see how you stack up on distinct days completed.
• Genius — After you conquer the campaign, unlock 100 deeper Genius stages organized in tiers (including tier bosses and a final capstone). Most complex puzzles may keep you searching for about an hour each ! Boss gates and tier rules keep the climb structured and satisfying.
• Random puzzle — Spin up a fresh layout from a random seed and pick a beginner, easy, or medium profile when you want something new without touching your campaign progress.
• Puzzle codes & library — Save, paste, or scan compact puzzle codes for replay value and sharing across players. Copy, show a QR code, or share layouts so friends can play the exact same board you enjoyed.
• Community gems — Browse community-submitted puzzles, vote for favorites, and share standout finds.
• Online rankings — Optionally create a nickname and compare best times on leaderboards per puzzle with other players.
Comfortable solving tools
Use pencil notes on cells, request a hint when you are stuck, and see mistakes called out clearly. A timer tracks your run; progress can resume if you leave mid-puzzle (when the same puzzle is opened again). Haptic feedback can be toggled in settings. Stats & Achievements summarize solved puzzles, daily streaks, campaign and Genius progress, saved codes, and a wide set of achievements (from first daily to long streaks and full-track milestones). New players can step through a short in-app tutorial that explains the cube rules and Kropki marks with illustrations.
Whether you want a few quiet minutes, a long-term mastery path, or speedrun challenges with online leaderboards, Kropki 3D Sudoku turns classic paper-and-pencil constraints into a tactile 3D experience you can take anywhere.
