the picture in this package be fascinating and my 7 year old daughter , who love math , have play this exclusively for the last month . the math be just the right level to provide a doable challenge . it be rather short -lrb- or else we be miss something -rrb- , but my daughter have play it over and over and enjoy as much each time . it do have a level adjustment , but we have not use that yet . -lrb- note : I like this better than Math Blaster 6-7 -rrb- .
