About this game
One rule. Hold the screen. Release at the exact instant the ring meets the line.
Miss by a hair and the run is over. Hit it, and the next one is faster.
Do Not Blink is a reflex game stripped to a single motion. There is no tutorial, no menu to
learn, no currency to farm. There is a ring, a line, and the twenty milliseconds where your
hand has to agree with your eye.
NEW :
- "twenty milliseconds" → "fifty milliseconds." The old number was invented. The real fairness floor in your code is HUMAN_FLOOR_MS = 52 — no streak is ever judged tighter than that. Now that the app prints milliseconds on screen, an invented number is a claim players can check.
- "A phosphor palette that unlocks as you go" → "Five phosphor palettes." The old line was vague and undersold it. There are exactly five past the free amber, and the ghost trail deserved naming.
- "Your best streak, kept" → "Your best streak, your best trial, your fastest reaction." Three numbers now.
- "It does one thing" → "It does one thing, three ways."
— HOW IT PLAYS —
Press and hold. A ring closes toward a fixed line. Release too early and you flinched. Release
too late and you blinked. Release in the window and your streak grows — and the ring comes back
faster than it left.
Most players stall around six. The wall is not your reaction time. It is the fact that at speed,
you stop watching the ring and start guessing where it will be.
— WHAT YOU EARN —
20 unlockable titles, each tied to a streak nobody reaches by accident. The early ones arrive in
a few minutes. The last one will take you a while.
A phosphor palette that unlocks as you go: the amber terminal you start on, and the greens,
ambers and whites of the machines it is imitating.
Your best streak, kept. That number is the whole game.
— WHY IT LOOKS LIKE THIS —
A monochrome CRT terminal. One colour, one line weight, no gradients, no particles. Every pixel
on screen is either the ring, the line, or your streak. Nothing is animated for decoration,
because at the speed this game asks for, decoration is noise.
— OFFLINE, ALWAYS —
The whole game runs on your device. No account, no sign-up, no cloud save, no server. Turn on
airplane mode and it plays exactly the same. Your streak and your titles are stored on your
phone and nowhere else.
Free, funded by ads. No in-app purchases and nothing to buy — there is no way to pay your way
past a streak.
— HONESTLY —
This is a small game. It does one thing. If you want depth, levels, characters or a story, this
is not that. If you want the specific feeling of a timing window closing and your thumb arriving
one frame early, it is exactly that.
— NOT FINISHED —
This update took the game from one mode to three, and that is not the end of it. More ways to be
measured are coming, along with your own numbers tracked over time. Still free, still no
purchases, still nothing to farm.

Don't blink.
Hold. Release on the ring. Daily trial, reflex test, one unforgiving streak.
