Reaction Time Games

Test your reaction time online and compare with friends. Free reaction time games — click when you see the signal, measure your milliseconds, share results.

Reaction time games measure how fast you respond to a stimulus — typically in milliseconds. Snapgame's reaction time games let you test your reflexes, compare your speed with friends on a leaderboard, and create custom reaction challenges for your group.

How to Create a Reaction Time Game

  1. Choose your reaction format — Pick a reaction type — color change, shape appearance, or sound cue — and set the number of rounds.
  2. Set difficulty and randomization — Adjust the delay range before the stimulus appears to make the challenge harder or easier.
  3. Share with your group — Publish the game and share the link. Friends test their reaction time and see their millisecond score.
