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!
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.
Features:
• Play in iMessages — send a co-op game to a friend and take turns at your own pace
• Post-game technique walkthroughs — step through the patterns on your board
• Apple Health integration — mindful minutes logged automatically as you play
• Game Center Multiplayer — Solve together in Co-op or race against the clock in Time-Attack
