Coreball has many levels, and each one gets harder than the last. As coreball levels go on, the core changes speed, direction, and behavior, making it harder for the player to time their shots correctly. Beginner levels have slow-moving cores and balls that are spread out far apart to help the player get used to the game. In the intermediate stages, the speed of rotation speeds up and the core starts to move in strange ways. At higher stages, you need to be very good at timing because the core moves randomly and there is less room to place the ball.
