Enjoy Sudoku is a Sudoku game for the iPhone. Enter a digit into each cell so that each row, column, and the nine 3×3 blocks contains all of the digits from 1 to 9 exactly once.

Play - Touching one of the digits at the bottom selects which digit is being entered. Touching a blank cell enters the current digit into the cell. To clear a cell touch it again while the digit currently in the cell is selected.

Selecting a game - Enjoy Sudoku offers one game at each of six difficulty levels each day. You can access today’s games or any game offered in the past seven days.

Pencil marks - Touching the pencil turns on pencil marks mode. When on, touching a cell places a pencil mark for the current digit in that cell, or removes the pencil mark if there is one already.

Highlight - When on, all of the cells that contain the current digit are highlighted in yellow. All of the cells that contain a pencil mark for the current digit are highlighted in pink.

Auto Pencil Marks - When on, empty cells automatically have pencil marks turned on for all digits which are not excluded by the current board position. When off, pencil marks may still be entered manually. Try with TestiPhone
