Ghost Thread

Hold to steer up, let go to steer down. Swing wide, clip the apex, and chase your own ghost or compete against friends around six original circuits, one lap at a time.

Race your ghost. Thread the line.

Ghost Thread is a one-touch racing game about the perfect lap. Hold anywhere to steer up, let go to steer down, and set the fastest lap you can. The camera turns with the track, so the road ahead always runs left to right.

THREAD THE PERFECT LINE Speed comes from how straight you drive. Every weave costs speed, and so does hugging the inside of a corner. Swing wide, clip the apex, run out wide, and the lap comes to you. A good lap is about 30 seconds, so there's always time for one more.

RACE YOUR GHOST Your best lap replays beside you as a ghost, with splits and a live delta that show exactly which corner the time goes in. Just ahead runs your rival: a gold ghost a little faster than you, usually another player's best lap. Beat it and a faster one takes its place.

WIN EVERY MEDAL Bronze, silver, gold and platinum on every circuit. Gold takes the ideal line. Platinum takes it with lightning reactions.

SEE WHERE YOU STAND End a session to see where your best lap falls among every other player's, then share a picture of it and dare your friends to beat it. Sign in to Game Center for leaderboards, achievements, and your friends' ghosts to race.

SIX CIRCUITS TO MASTER • Ardennes: a hairpin, a plunging left-right-left and a fast sweep home. • Swirl: a hairpin at the top of the hill, esses and a three-apex swirl. • Snake: esses up the hill, a hairpin, a fast sweep and a chicane. • Mirage: a long straight into a hairpin and an angular stadium climb. • Island: long and narrow, with chicanes down both sides. • Harbor: a street circuit with a climb, a hairpin and a curving tunnel.

New to racing lines? Apex School is a short lesson in one: when to turn in, where the apex is, and when to ease back out. And any circuit can show you its ideal line.
