The game is a mascot kart racing game, very similar to other games in its genre like Mario Kart, Konami Krazy Racers and Crash Team Racing. Characters race through various race circuits themed on different Sega franchises and collect power-ups to boost their speed or hamper their opponents. The items have a rock-paper-scissors effect, in which certain items can be used to defend against others. Also, on occasions when players get three of one item, they can choose to fire/activate them at the same time. Additional boost can be earned by successfully executing drifts (with longer drifts earning more boost), or performing tricks while in midair. Like Sumo's previous Sega game, Sega Superstars Tennis, each character has a special ability (called an "All-Star Move") unique to them that they may use to their advantage (such as Sonic transforming into Super Sonic and AiAi riding in his monkey ball), which they can obtain if they are running behind in the race. How long each All-Star move lasts depends on the character's current position.
