How to play
- Your role: you are a truck driver.
- Objective: drive along the road while avoiding other trucks, and collect points by picking up diamond-shaped icons.
- Colours: the collectible icons are always in the opposite colour channel from your truck. You need red/blue glasses (red filter on the left eye, blue on the right).
- How it ends: the game ends when you have collided with three other trucks.
- Colour swap: at regular intervals the colours switch, with a brief flash.
- Brightness balance: the balance between the two pictures changes in steps as you play; the level at which the session ends is saved to your account as your score.

Before you play
Calibrate the screen (the game guides you), keep the room evenly lit and take breaks. See the getting-started guide and the explanation of dichoptic therapy. The game is a wellness and training activity, not a treatment, and no health benefit is claimed.
