Has lots of great options for various levels of play! My 7 yr old was able to grasp the idea of Sudoku with assistance from the game.

Took my 7 year old two times playing to figure out the "lower" # every time trick. This app now has no point to learning facts. Disappointed that programmers didn't think kids were "smart" enough to figure that out. :) fix that and we'll have a teaching app. :)

Really makes me think and it's a good one to pick up right where you left off! Good if you like word puzzles.

Lots of fun

Great info to make a decision based in all info and your parenting comfort level with various topics and various children! BUT!!! The app is sooooo slow and times out when I'm looking even for new releases?
