How to play
Choose a circuit and either Race or Time trial, then select Play. Complete one lap. In Race, finish ahead of five rivals; Gold requires first place within the circuit target time, Silver requires a top-three finish, and other finishes earn Bronze. In Time trial, beat the target for Gold. Leaving the road reduces speed; contact with rivals or the outer rail slows you down. Boost consumes energy and refills when released. Pause with P, and use Restart to begin again.
