You can merge the ball with another one that has the same number and color.
Naturally, you cannot jump. If you want to pass a rail, it's essential that your ball is bigger than the rail. This is not a race, but an epic, fun and exciting runner type simulator to make you feel like you are on a roof top without rails. You do not have to stay on a rail—you choose your own way!

How to play:
- Tap and swipe to control your always rolling ball.
- Merge balls with the same number and color to level up the ball.
- Be careful with the spikes and other blocks on the road, which will lower your ball level.
- In each level, there will be spikes and balls. You have to overcome all and reach the finish line to receive the reward.
