User reviews

The best minimalist sudoku with colors!

I like how this is a minimal design to center your focus with colors on the puzzles with the same Sudoku principles. The only suggestion I’d like to make here is to add an ability to see only the highlighted color in the puzzle when a specific color is tapped on the screen. This would help see and focus a lot better for most people. Best app!
