You just need to match shapes but in a different way. In the first level, it shows 4 shapes but it'll add more characters (shapes) in next levels. Yes, as you cross more levels difficult increases and you've to remember more and more objects. It's a real challenge so test your brain capacity!
Yeah, TUFA features global leaderboards where you can see who is currently playing and high scores. The game is a quite enjoyable. It's a super fun for all ages and skill levels.
