How to play
| Mode | What to do |
|---|---|
| Classic | Tap to start. When the screen turns green with a solid disc, tap. |
| Hold & Release | Press and hold. Lift your finger the moment the signal appears. |
| Decoy | Colors flash to bait you. Only the solid disc means go. |
| Choice | Four pads. Tap the one that lights up. A wrong pad is a foul. |
| Sound | Turn your volume up and tap the instant you hear the beep. |
Each round has 5 or 10 valid trials (change this in Settings). Responding before the signal, or faster than 100 ms after it, is a foul and that trial is replayed.
Common questions
Why is my score the median? One lucky tap can't inflate a median, so it's a fairer measure of your real speed. Your best single trial is shown too.
Sound mode feels slow with AirPods. Wireless audio adds delay. Use the speaker or wired headphones for accurate Sound results.
I'm color-blind. Go always shows a solid disc, and Settings has a blue/amber palette.
Leaderboards won't open. Sign in to Game Center in the Settings app, then reopen QuickBlink.
Where did my version 1 results go? They were imported into Progress under Hold & Release.
Can I move my results to a new device? Results are stored only on this device and are not synced.
