About GGReflex — Free Reflex & Skill Games

Fourteen small browser games that put a number on something your hands or your memory can do. Reaction time, click speed, aim, four kinds of memory, typing, and a couple of things that exist purely because they were fun to build. Nothing to install, no account, and it works on a phone.

What makes this different from the other reflex sites

  • Every game page explains exactly what we measure and what we cannot — including the display and mouse latency that sits inside your score and that no browser test can subtract.
  • Where we quote a number, we say where it came from. Where a figure is folklore that players repeat to each other, we say that instead of dressing it up as research.
  • We have publicly corrected the claims we used to get wrong, rather than quietly editing them.

That sounds like a low bar. It turns out not to be: most of this corner of the internet runs on numbers nobody has ever checked.

Where to start

The reaction time test is the classic one and takes about thirty seconds. Click speed is the one Minecraft players argue about. If you want to feel bad about yourself quickly, the chimp test will oblige — and its page will also tell you the part of that famous chimp-versus-human study that everybody leaves out.

Scores go on a global leaderboard if you want them to, with filters for country, device and time period, and the live distribution of everyone's results is published openly on our stats page, sample size and all.

Frequently asked questions

Is GGReflex free?

Yes, all of it, with no account and no install.

Do my scores mean anything?

They mean something about you compared to your own previous scores on the same hardware. Compared to a stranger's score, they mostly mean something about the hardware, because display and input latency are inside every timing measurement and vary enormously between devices. Each game page explains its own version of this in detail.

Will playing these make my reflexes faster?

Practice will make you better at the specific test you practise. Whether that carries over to anything else is a much weaker claim than most reflex sites make, and we are not going to make it.

Does it work on a phone?

Yes, though your timing scores will be worse than on a desktop — touch input adds latency a mouse does not. The leaderboard has a mobile filter so you can compare like with like.
