The Reaction Trainer is a reaction time test built to sharpen your CS2 reflexes. Four modes: Simple Click (red screen turns green), Flick Reaction (click the target), Go / No-Go (impulse control) and Audio Cue (directional sound). Every reaction is timed in milliseconds, and each session ends with your best, average and accuracy — free, no account needed.
Yes, free with no account. Pick a mode and play directly in your browser.
Simple Click: click as soon as the screen turns from red to green. Flick Reaction: a target appears, click it as fast as you can. Go / No-Go: shoot green targets, ignore red ones. Audio Cue: a sound plays left or right, answer on the correct side (click or A and D keys).
Every reaction is timed in milliseconds. Each session ends with your best time, average, worst time and accuracy; false starts are counted.
Not to play, only to save: with a free account your best times per mode are stored, your 7-day history is displayed, and you can unlock trophies and enter the leaderboard.
