Reaction Time — free online

Wait for green. Tap instantly. Your milliseconds, ranked against your pride. This is one of 32 tiny games on TinyPlay: every run ends with a score out of 1000, a grade, a shareable score card and a challenge link that dares a friend to beat you.

How to play

Open this page and the game starts in its own play page — no sign-up, no download, about 10 sec per run. Play once for a score, then use the challenge link on your result page to send that exact score to a friend.

How we measure

Timing starts the moment your finger or mouse button goes down, not when the click event fires after release. A tap within 100 ms of the signal is treated as a lucky guess, not a reaction — athletics uses the same line for false starts. The wait before the signal is random, so rhythm tapping does not work. Remember that a browser adds roughly 80 ms of delay nobody spent, and a touchscreen adds 35–140 ms more; compare scores on the same device. The average human visual reaction time is about 273 ms; under 250 ms is good and under 200 ms is excellent.

What is a good score?

Score	Grade	Tier
950–1000 pts	S — Legendary	Top 2% tier
850–949 pts	A — Elite	Top 8% tier
700–849 pts	B — Sharp	Top 20% tier
500–699 pts	C — Solid	Top 43% tier
300–499 pts	D — Warming up	Top 70% tier
0–299 pts	E — Brave attempt	Everyone starts here

Tips

Do not anticipate the green — a too-early tap voids the round. React, never guess.
Keep your finger or cursor hovering over the tap zone so the movement distance is zero.
Compare scores only on the same device: a browser adds roughly 80 ms of delay nobody spent, and touchscreens add more (see our phone vs mouse guide).
Take the median of several runs as your real number — single runs scatter by about 40 ms.

FAQ

Is Reaction Time free?
Yes. Every TinyPlay game is free, with no sign-up and no download. An optional free account only saves your points and leaderboard places.

What is a good score in Reaction Time?
Scores run 0–1000. 500+ is solid (top 43% tier), 700+ is sharp (top 20%), 850+ is elite (top 8%), and 950+ is legendary (top 2%). Tiers follow the score scale; they switch to the real player distribution once enough scores are collected.

How long does one game take?
About 10 sec. Getting a score takes under a minute; beating it is what eats the evening.

Can I challenge a friend?
Yes. Finish a run and your result page gives you a challenge link for this exact game, carrying your score. Whoever opens it plays the same game and the winner is decided on the spot — and every rematch deepens the challenge chain.
