Sudoku in color — toggle numbers and colors mid-game
When you're stuck on a number puzzle, flipping to color mode can reveal patterns you couldn't see before. It's not a visual theme — it's a solving strategy. What makes it different: - Mid-game toggle between number and color mode - Difficulty defined by solving technique (Expert = X-wing and above) - Daily challenge — same puzzle for all players worldwide - Full colorblind support with Okabe-Ito palette + shape symbols - No mid-game ads, ever Free on iOS. No account required.
Hi Product Hunt! I'm Layne, the solo developer behind Kaleidoku. The core idea came from the Colorku board game — which replaces Sudoku digits with colored wooden marbles. I always thought that mechanic deserved a great mobile app, so I built one. Happy to answer any questions about the app or the build!
