About the game
Sudoku, quiet and green. Every puzzle has exactly one solution and was rated by a solver, so Easy only needs singles and Expert really is expert. 160 puzzles across Easy, Medium, Hard and Expert. Notes tidy themselves up when you place a digit. Undo and redo go all the way back, and a hint fills one square at a time. Three mistakes ends the puzzle. You can turn that off in settings if you just want to relax. I made this one for my amma, who does a sudoku every evening.
How to play
Tap a square, then a number. Or use the arrow keys and 1 to 9. N turns notes on and off. Backspace erases. Ctrl+Z undoes, Ctrl+Y redoes, H gives a hint. Esc pauses and hides the board.
