F1 Circus is a Formula 1 simulation racing game. Unlike later entries in the series, this version does not feature an official license, and so only features generic teams and drivers. Races are viewed from a top-down perspective, and there are a variety of machine settings as well as basic vehicle damage.
A total of 15 courses are on offer, and there is a World Championship mode, as well as a "Constructors" mode for one or two players where the player can take the role of team manager while the computer does the actual racing. The Famicom release also adds a Time Attack mode for practicing and perfecting each course.
The game's gameplay involves navigating through tracks at high speeds, using various machine settings to gain an advantage over opponents. The game also features basic vehicle damage, which can be repaired or replaced during races.
