Space Race is a game in which the client controls the position of three racing spaceships based on reward and inhibit thresholds.

Meters on the screen indicate the amplitude of the inhibit and reward bands.

Reward conditions enable the audio and the thrust of the center ('reward') spaceship, making it fly ahead of the side ("inhibit") spaceships.

The meter at the bottom of the screen indicates how long optimal focus is being sustained (maintaining a rewardable state with no inhibits). Sustained focus causes the reward spaceship to enter hyperspace, accompanied by stars whizzing by.
