This is just a theroy (a game theroy!), but... I think the Amie mini-games are made for diffrent kind of learners. Head it! is auditory, you hear the yarn, and you hear when you hit it. Berry picker is Kinesteitc, you have to be quick and active. Tile puzzle is Visual, you have to see (and make) the big picture. Based on this, what kind of learner are you?
