It's a easy game and it can open your mind. In the game, there will be five balls one inside is broken.There will be a hint of the weight of the broken ball(for a example, lighter or heavyer). If you could find the correct one, you'd be a smart man! Drag the ball to control.
Do you see the typo in the start screen? Don't think about it.It's only an error. All credits by me.
