KaizenDoku is the Sudoku experience designed for players to enjoy solo, or side-by-side with a friend. Play together right inside iMessages. Start a co-op board from the iMessages app drawer, send it to a friend, and solve it together, taking turns at your own pace. The game bubble updates after every move so you can leave and pick the puzzle up at any time. Team up in Co-op and solve a board together or race against the clock in Time-Attack. Every multiplayer match is fully supported by Apple Game Center, so your wins, best-time, and progress are posted on Game Center leaderboards and backed by Game Center achievements. Share and compare with all your friends! Learn from every board. When you finish a puzzle, tap the star to review it. Step-by-step walkthroughs show solving techniques on your own board, from Naked Singles to X-Wing and Swordfish, and mark which ones you used. Single player logs mindfulness sessions — a continuous improvement practice inspired by the Kaizen philosophy. KaizenDoku logs your mindful minutes directly to Apple Health, turning your daily puzzle solving skill into a measurable wellness practice.
