The goal of the game is to move the GraviBall from start to finish. Along the way you can grab bonuses and power-ups. As the level of difficulty increases, obstacles appear. The game consists of 5 levels and countless possible solutions.
Interaction
The ball must gain some speed to reach the target. Start by raising it above the rest of the terrain. Next, shape the sand into a slope, similar to a bobsled track or a water slide. Your track should end at the finish point. Now all you have to do is release the ball and check your construction. Once the ball is released, you can’t change the terrain. If you fail, improve the track and try again. Aim for all the bonuses for maximum points.
Buttons
Single: Press once to release the ball. Press again to reset. After successfully completing the level, a single press will advance to the next level. Press and hold for 5 seconds to replay the same level.
Two buttons: Press the right (blue) button to release the ball. Press the right button again to reset. After successfully completing the level, pressing the right button will advance to the next level. Press the left (green) button to replay the same level.

Touchscreen
Tap the arrow at the bottom of the screen to open the roll-up menu. From there, select ‘GraviBall’. This will open the mode. A large play button (triangle) will appear on the screen. Tap it once to release the ball. Once the ball starts rolling, the triangle will turn into a square. Tap it to reset the level. After successfully completing a level, you will see a replay button on the left and a skip button on the right. Both buttons have captions explaining what they do.
