Jezzball is a game by Dima Pavlovsky included as part of Microsoft's Entertainment Pack series. In the game, atoms constantly bounce around a rectangular playing field. To advance to the next level, you must clear 75% or more of the playing field by partitioning it off. Get hit by a ball or run out of time, and you lose a life.
- Endless Game: Each new level has one additional Jezz; eventually you'll get enough that the level is effectively a Kill Screen.
- Excuse Plot: One of the sillier ones: "On a far-off world, a new kind of atom has been discovered. It's called a Jezz, and you get paid galactic credits each time you trap one for shipment back to Earth. The Jezz atoms preserve their energy best when tightly confined, so the smaller the chamber you trap them in, the more galactic credits you acquire."
- Hyper-Destructive Bouncing Ball: Ever-increasing amounts of these.
