Prime Sudoku — About This Game

Another take on the nine-by-nine number grid, this one opens by asking which difficulty you would like. A cell is selected with a tap and then filled from a number pad, while an erase button removes anything entered by mistake. Described as relaxing rather than pressured, it works as a quiet logic puzzle for players who already know the rules.

How to Play

Pick a difficulty, tap a cell to select it, then choose a number to enter; the erase button clears mistakes.
