How to play

The needle sweeps up the gauge as pressure builds. There is a green safe band on the dial. Vent the moment the needle is inside it. Land it dead centre for a perfect vent and a bonus. Vent below the band and you dump good flow for nothing, costing you points. Let the needle pass the band into the red and the line bursts. The run ends there. Each clean vent moves the band and speeds the climb, so the timing window keeps getting tighter.
