In the standard "Classic" and "Knockout" modes (called "Games"), up to 32 players compete in matches with battle royale-style gameplay. Players, represented as jellybean-like figures, move around in a three-dimensional playing field, with abilities such as jumping, diving, and grabbing/mantling. The aim is to qualify for subsequent rounds by successfully completing each of the randomly selected mini-games, many of which have randomly selected variations.There are currently seven different types of levels in Fall Guys.

Courses, which involve navigating obstacles to reach a finish line; Survivals, which involve outlasting either a timer or certain number of other players; Points, which usually require you to score points by collecting items, jumping through hoops, or staying in a scoring zone; Teams, which are currently exclusive to Duos and Squads modes, require you to work together with other players in a Points-style level; Logics, which involve memorising fruits or solving puzzles; Invisibeans, uneven Team levels that only appear for limited times in the Game Selector; and Finals, which end a match, involving either being the last player standing or the first player to finish an obstacle course.

The winner of the Final level is usually the winner of the match, except in Duos and Squads modes where the winning player scores the victory for their whole team.
