The game style of Geometry: Black Ball is similar to the popular game genre Geometry Dash, but in this case you will use gravity disabling. Click on the moving round object to make it jump and catch on the ceiling, continuing to move, the next click will lower it down. Make sure that the object does not crash into the obstacle, and you can collect the coin if you have time. Gradually the speed increases, and the number of obstacles increases. Your reaction must be lightning fast in Geometry: Black Ball.
