On a phone: drag anywhere on the left half to steer. Your kart speeds up by itself. Hold DRIFT through a turn and let go for a turbo, tap ITEM to fire, hold BRAKE to slow down or reverse, tap SWAP to switch items, and tap II to pause.
Hold accelerate during the "1" of the countdown for a rocket start. Yellow arrow pads give a free boost. Gamepads work too (A gas, B brake, RB drift, LB or X item).
Race your ghost: the blue see-through kart is your fastest run, or the world's fastest if you pick World best. Grand Prix runs all 4 worlds in a row for points. Finish on the podium to unlock karts and paint.
Auto starts on high detail and drops to low by itself if the game runs slowly. Touch steering sets how far you drag for a full turn (higher turns with a shorter drag).
Make a room and send the 4-letter code to up to 3 friends. Everyone races the kart and face from their own garage.
Turn your phone sideways to race.
