This is a fun App to play and is ideal for those that are new to Sudoku as it has an optional skill level for novices that leads you through the process. For a standard game there is the option of the harder setting ,although it will not test the advanced player, it may surprise him at times.
Rewarding to play with nice graphics.It is an excellent way to train the mind of the young (and the not so young) in powers of concentration and logic.
Note that this App contains no advertising or in-app purchases.
