KartWorld combines isometric-perspective kart racing with light management/sim elements to give the player a feeling that they are running a successful racing team. Through purchasing karts, racing them and providing services to generate income, the player attempts to rise to prominence in the racing world as a legend.

KartWorld comes with an integrated quest system, pushing your forward through specific tasks like refueling visiting cars, building new vehicle bays in your shop, visiting friends and even completing race challenges. These races require fuel to run, which recharges over time, or can be purchased with Kart Cash, the game's premium currency. Once you're ready to put the pedal to the metal, you'll be able to simply drag your mouse, without clicking, around your screen to steer your karts; the farther away from the kart you hold your mouse, the faster the kart will drive.
