Simple Sudoku is a simple memory puzzle game that brings the timeless classic to your fingertips!

Sudoku boards are generated using an algorithm. They are not human reviewed. They are simply randomly generated sudoku boards with the target amount of empty cells based on the board difficulty.

Sudoku difficulty is defined by how many empty cells a new sudoku is generated with:
• Rookie - between 29 and 33 empty cells
• Easy - between 34 and 37 empty cells
• Medium - between 38 and 42 empty cells

When all empty cells are populated, Solve button becomes enabled. Press it and see if you solved the sudoku board successfully. In case of the incorrect solution, cells with duplicate numbers will be highlighted. Such cells needs to be reviewed and corrected taking into account the whole sudoku board to ensure that the new solution is correct one.

On rare occasions, a sudoku board might be generated with several correct solutions. Meaning, although there will be no duplicates on the board, some empty cells can be populated in either-or fashion without allowing impossible duplicates to be on the board as the final solution. When you come across this, you will see it.

Your sudoku board is persisted across sessions on your device. In other words, if you start solving a sudoku board and then close the app, restart your phone, etc. then upon opening Simple Sudoku again, your board will be in the state you left it in during your last session.

Simple Sudoku does not use cloud capabilities to preserve your sudoku board across devices.
