Check your reaction time

How to play

After starting the reaction check, you need to tap the screen just in time for it to turn green. If "Infinite" mode is selected, you can restart the check an infinite number of times, and fine-tune the check parameters. If "Challenge" mode is selected, you gain access to the rankings, where you can climb through the leagues—from the lowest (Bronze) to the highest Master League. To move up to a higher league, you must achieve a certain average time over a specific number of checks. Good luck!
