A free program for Android, by UnknownProjectX.

This free Sudoku game is for those who love solving puzzles. It’s also perfect for beginners to learn how to play, as well as for those who want to keep their brain sharp.

The goal of the game is to fill a grid with numbers from 1 to 9, without repeating any numbers within the same row, column, or box.

You can play on your own, or compete against others on a local network. You can even play against the computer if you want to get an advantage.

To help you keep track of the board, you can add a number to a cell and it will show up in the numbers you can use for that cell.
