This game is very good for those children who are just starting their math journey in addition. It does give you an option of choosing the sum value you wish to review. I would like to see this program expanded to cover all basic operations. The encouraging voice after successfully solving the question can get boring after a while. It would be nice to see the artificial voice be given a larger base of encouraging phrases OR even add to this game a break option.
