No brakes, all downhill: the steeper the street, the faster you go. All you can do is steer.
Steer: hold the ◀ and ▶ buttons, or pick Tilt and tilt your device. On a computer use the arrow keys (A and D work too).
Pick a street: a green sign before every intersection names the street left, straight on and right. Be on the left or right of the road as you cross to turn; stay in the middle to go straight. ⛰️ steep streets are fast, ⛽ fuel streets have lots of fuel cans, 📦 box streets are flat and full of boxes.
Fuel: the gauge top left keeps the engine running. Grab the red cans to fill it.
Bumps cost fuel: market stalls, fruit carts, cones, hydrants, cars and buses. The bigger the thing, the more fuel you lose, and it slows you down.
Never stop: out of fuel, only a steep hill keeps you rolling. If the car comes to a complete stop, it explodes.
Honk: tap HORN (or Space) and everyone crossing ahead dives for the curb. Anyone you miss tumbles away like a cartoon, never hurt, but it costs fuel.
Points: distance, smashed boxes, fuel cans, and near misses (25 each). Fuel left at the finish pays 5 a drop.
Drive my street: the same drive on real streets, from the map of a town near you (or any town you type). The signs show the real street names and the shops on each side are the real ones. Main roads are the steep streets, side streets the fuel streets, alleys the box streets. A dead end turns you round.
Medals: reach Mattress Mountain for bronze, silver with two bumps at most, gold with none.
