Free Reaction Time & Speed Games
Fast is useful only when you know what you measured. Try a reaction or speed game, keep your setup fixed, and compare typical attempts rather than one lucky record.

A clear plan beats a random list
Try a free week of reaction & speed practice.
Ten minutes a day. Games, an offline exercise and a simple practice log.
Reaction, aim and typing are different tasks
Reaction Time measures the delay between a visual change and your response. Aim Trainer adds pointer movement. Typing Speed measures text entry. Color Match and Quick Math add a decision. A faster result in one game does not imply the same ability across the others.
Your device is part of the score
Screen refresh, browser scheduling and input latency all affect browser timing. A touchscreen and mouse are not interchangeable measurement tools. Use the same screen, browser and input method for a personal comparison, and write down any setup change.
Use a warm-up with a stopping point
Try one reaction round, one aim round and one decision round. Keep it short and use a comfortable pace. There is no guaranteed transfer from these exercises to competitive game performance. The Reaction Reset plan helps you organise the routine and review your own scores.

Common questions
Is a browser reaction test laboratory accurate?
No. It includes display, browser and input delays. It is useful as a casual task and for comparisons on a consistent setup, not a laboratory measurement.
Should I compare mobile and desktop scores?
Keep those records separate. The display and input method can change the measured delay substantially.
