It’s a game of physics where you try to move the pink shape, be it a square, circle or triangle, into the pink box. It gets progressively harder as it goes on (read: when you get to the second level!) and I would say it’s not one for the kids…or adults for that matter, unless you have a PhD in this sort of thing. But it’s fun all the same .
