In this exciting game you have to guide a big ball up a narrow tunnel. Starting from the walls, he will rise higher and higher until he reaches the highest point. However, getting there is not easy. After all, there are sharp spikes on the walls. If you hit one of them, the game will end. And, if you want to earn extra bonus, collect gold coins. How many of them will be in your gaming piggy bank depends on how many points you earn in the end and whether you can set your own personal record. Good luck!
