Hold. Wait. Release the instant the lights go out.
Lights Out is a five-light reaction test. Five red lights come on, one every second. They stay lit for a random moment, then go out. Let go the instant they do. Your reaction is timed to the millisecond, and there's nowhere to hide: go early and it's a Jump Start.
PLAY YOUR WAY
• Grand Prix: a start whenever you like, with every result placed on a 22-car grid of simulated rivals and your Game Center friends.
• Qualifying: three attempts, and your best one counts.
• Daily: one start a day, the same lights for everyone in the world. A new one every midnight UTC.
SEE HOW QUICK YOU REALLY ARE
• Every result is color-coded, from Legendary purple to Sleepy grey, on a ruler that shows exactly where you landed.
• Earn a racing license from your recent form and climb seven grades, from Karting to World Champion. It moves with you, so you have to keep it. Share it as a picture.
• History shows your trend, how consistent you are, your quickest time of day, and a short debrief of what's changing.
• Nineteen achievements, from your first clean start to a few you'll have to find for yourself.
COMPETE
• Game Center leaderboards for the Grand Prix, Qualifying and the Daily, with friends or the world.
MADE TO BE LOOKED AT
• The moment you press, everything else disappears and only the lights are left.
• Four color themes, light and dark, three light colors and adjustable brightness.
FOR EVERYONE
• Reduce Flashing, sound, haptics, and an audio cue for players who can't see the lights well.
PRIVATE BY DESIGN
• No ads, no tracking, no account, and nothing to unlock. Pay once.
• Your history stays on your device and, if you like, syncs through your own iCloud, which only you can see.
• Tips are optional and unlock nothing.
A note on flashing lights: Lights Out shows bright red lights that come on and go out. If flashing lights affect you, turn on Reduce Flashing in Options, or check with your doctor before playing.

A fairer Daily.
• The Daily's timing now comes from a secret fetched each day instead of one built into the app, so nobody can work out a day's lights in advance.
• If today's Daily can't be loaded, for example with no connection, the app now says so and offers Try Again. Practice runs still work.
