Something like that game pou you have on android . As I see kids love that game . Maybe a game with lots of funny little games in it
Something they can play when they're offline - like on the bus to school. Most kids don't have data and they get frustrated when games won't play without some sort of internet connection.
Good point the offline part. Do you have experience with kids of these years? Because it's such a practical problem, that one can't really guess a-priori. Regarding the idea, if you are on the search for one (I think that was the point of your thread, just miscomunicated) I was thinking something more along the lines of Roco Loco, because it requires a constant interaction, and one which is in a different scale than just screen touching or button pressing. A kid would love the feeling of deeper imersion, and at the same time the mechanics are so intuitive that they don't have to be explained. While, you can also manage to throw in some elementary science, as in comunicative pipes, leverage, intelligent distribution of weight, maybe even add colouring and splitting. The only problem is that it's not original. But... it doesn't have to be a blob. Just think about it.
