How to play

1Start a match and find the aim control, which is usually a mouse drag, a swipe, or arrow keys to position.
2Set power with a meter or by how far you drag, and release at the right moment to execute.
3Aim for the gaps rather than the target. Corners of the goal, edges of the hoop, open lanes on the court.
4After each round, check the scoreboard and adjust your power or angle rather than repeating the same shot.
