What is Reactionle?
Reactionle is a free daily timer precision game. A visible timer counts up from zero and your goal is to stop it as close to exactly 5.000 seconds as possible. You get one attempt per day — no do-overs, no practice runs. How steady are your reflexes when it counts?
How to Play
Click the Start button to begin the timer. Watch the seconds tick upward and click Stop when you believe you have hit 5.000 seconds. Your final time and the difference from the target are shown immediately. Share your result to challenge friends and come back tomorrow for a new attempt.
