MULTIPLE LEVELS / UNLIMITED RANDOM GAMES
iSudokuToo allows you to play UNLIMITED games categorized as either Easy or Normal.
Besides this, you could create your own game, you just clear the board, enter the initial values and select the option of Custom Game to start playing it.
At any time in the game you can go and verify if you are on the right path.
The game provides two keypads, the one on the left is to keep track of all the cells that you think you have resolved; the other one is for annotations that you want to provide for a specific cell (in others words, for possible values that a cell could have).
Also, in the main screen there are two options that allow you to validate or clear ALL the annotations that you have in the board.
If you decide to give up, you can select this option to see the right values on the board.
It is possible to save a current game and start another one, and continue with the first one whenever you want.
This will show you the list of all the games you have saved (that are not finished yet).,
