Sonic Riders takes place when Dr. Eggman challenges Sonic and his friends to a Worldwide Grand Prix, with the prize being an ultra-rare Chaos Emerald . The game features gliding on air boards, each designed for individual playable characters, creating a sense of sports-style racing tension as players perform tricks and stunts over challenging terrain.
Players control Sonic and his friends as they speed through tracks on air boards, using special moves to take down opponents. Air is a crucial element in Sonic Riders , with each board needing "fuel" from the air to function. Players can refill their air at designated points but must use other methods to replenish it, such as performing tricks with their board. Additionally, using turbulence created by other racers ahead can give players an advantage.
