Gravball is a popular game played by humans since the mid-25th century. The game consists of a floating gravity ball, and it is played on repulsor courts. The gravball is "skimmed" across the court, although the mechanics of the game have never been described.
Gravball lends itself easily to military training exercise and many UNSC drill instructors have worked combat elements into the game and use it in training regimes. In 2558, a variant of the game was incorporated into War Games simulation aboard the UNSC Infinity.

Historically, UNSC drill instructors have utilized a variant called Ricochet, where fast-paced combat simulations occur in synch with the classic, frenetic scoring competition. Spartan-IVs aboard Infinity have adopted this format recently in the ship’s impressive combat decks, incorporating a number of adjustments within the War Games simulations in order to effectively hone their skills.
