Circuit Nine

The circuit is built from a 32-bar beat pattern at 128 BPM: corners fall on bar boundaries, chicanes are the syncopation, and a boost pad lands every bar's worth of track. Cross a pad within 120 milliseconds of the beat and it fires. Cross it late and it gives you nothing — you are just driving.

How it plays

• Three laps of a 1,273 m circuit — 12 straights, 15 corners, 3 chicanes and 2 ramps, all derived from the pattern.
• 86 pads across a run. Chain them on the beat and the boost multiplier climbs 1.0×, 1.15×, 1.3×, 1.5×; cross one off the beat and the chain resets to nothing.
• Downbeats pay extra — the boost lasts half again as long. Holding 42.4 m/s puts a pad under you every two beats, so the fastest gear is also a tempo.
• Hold Shift to drift. Grip drops from 0.85 to 0.25, a meter fills in about a second, and releasing it full gives a 1.1-second slipstream worth +30% top speed.
• No crash-out, no rival, no timer to fail. You always finish; the results screen sets your time against par.
