Reaction Tests

Published on May 27, 2020

I recently became interested in reaction times and how it effects gaming - and it turns out that reaction time per se is actually pretty consistent between different players (about 250ms). It’s other skills, like hand-eye coordination, pattern recognition, and automatic decision-making, that make games easier or harder for different people.

So naturally, I wanted a way to measure these skills and compare them to other people. I’m not sure I succeeded in that, but it was fun to build and I got an excuse to play with PICO-8 a bit!

Play it in your browser (only takes about 5 minutes, tops):
