It's about making the most points at the different offers you the game, trying to get the ball to the house and avoiding falling into the skulls.
At the beginning you have 3 lives and a ball of green.
When you save all the balls, you come out again all over one.
When the ball lands on a skull will remain a life and if you still have back out from the start.
White circuit will always equal but gray links can be exchanged by pressing the screen.
Each time you touch the screen, all gray connections between the routes sequentially change for next connection that touches.
I hope you like it.
