The game is very simple: the objective is to get to the end of the level. The way to get there is to take the shortest path, which may be a straight line, a corner, or a corner to a corner. You can only move in the direction you want to go, and you can only move to the next level when you're on the level.
This game is great for kids and people who have a short attention span. It's also great for people who want to play a game but don't want to do all the work themselves.
