The ball's density also varies, but players don't learn the value until after choosing their raquets. The infamous 'bowling ball table tennis' region of the parameter space often leads to equipment damage.
[Megan and Cueball are playing a game that looks similar to tennis. There are courts, but on each multiple parts of the game are different. On each, Cueball is on the right and Megan is on the left.]
[Top left: The court is small, each half slightly wider and deeper than a person is tall, and the ball is extremely large, about twice the height as the players' heads. The ball has just bounced on Cueball's side very slowly, and he is about to hit it.]
[Top right: The court, ball, and net closely match a regular tennis game, albeit perhaps a slightly more ground area than a doubles' court. Cueball has just hit the ball, and it is currently flying towards Megan's side.]
[Bottom left: The ball, and net are basically the same as in table tennis, but the 'court' is a much smaller tabletop. The ball has just bounced back up on Megan's side, and she is poised to hit it back.]
[Bottom right: The court is slightly larger than the top left, while the net and ball are massive, with the ball at least double the radius and the net significantly over twice the height of the players. Cueball is apparently fighting to push the huge ball high enough to get over the net, indicated by movement lines in which he is barely managing to keep the ball on the racquet itself, not to mention he has only gotten the ball halfway up the net.]
[Caption below the panel:] Parameterball is a raquet [sic] game divided into four quarters, with ball size, court size, and net height randomized each quarter.
