I bought this game for my 12 year old son who asked for it, and he doesn't even play it. My daughters play it and they are 5 and 6. The few games they have on here, are mainly for kids under the age of 12. Fun, but wouldn't recommend for older kids.
My 5 year old loves this - especially the game where the Miis have to balance on the ship. Good mix of short games and longer ones. Even our 3 year old can play some of the group games
Fun for the whole family and it never get's old...it's one of my favorite games!
