Games Sudoku game

I have made a Sudoku game in Unity and uploaded to google play store. It is still a work in progress with a lot of scope for improvements and also more features may need to be added. All are welcome to try it and put in their valuable suggestions for improvements.

I like your project but i don't know how to play this game.

 

The game has a 9x9 grid of cells sectioned into 3x3 grids. Just tap on a vacant cell and then tap a number button at the bottom to enter. The entered number should not be repeated in the same row and column as the selected cell. Also, the same number must not be repeated in the 3x3 section it lies in. If a wrong entry is made, the entry will turn red. You can then make a right guess to enter it again. You can reset the whole game to its starting point by tapping on reset button and also undo the recent entry by tapping on the undo button. You can make notes of probable entries in a cell by tapping the Notes button ON and then tapping on the number buttons at the bottom. Hope it will help.
