Sports Games simulate real or fantasy sports within Rec Room. Some - but not all - of these Custom Rooms implement game rules using Circuits and the Roles system.
^SaintsBasketBallArena is a basic implementation of a basketball court.
^Boxers is an implementation of boxing in Rec Room.
Disc golf maps are player-created games that re-implement the game mechanics of #RecRoomOriginal Disc Golf.
Examples of custom disc golf maps are: ^DiscGolfInClearCut, ^DiscGolfInForest, ^DiscGolfInForestAtNight and ^DiscGolfInPark. (These are all based on ^DiscGolfTemplate.)
Velp has created another template for implementing disc golf: ^golftemplate.
^DualLineKite is an implemantation of a dual-line kite for a single player.
^QuidditchRecRoom is an implementation of the ball game from the Harry Potter universe.
Example of first-person racing maps (for walking mode) are ^RecKarts, ^PodRacerRecEdition, and ^SpaceWarslvl2. Examples for race tracks for RC Cars are ^Rectona500 and ^RecRoomSpeedway.
^largeTennis and ^FutureTennis are two tennis implementations.
Ultimate (frisbee) has been played as an impromptu game for a long time in Rec Room, but it also has been implemented as a Custom Room with built-in rules in ^UltimateFrisbee5v5.
