Description:
Whac-A-Mole. After pressing the start key, the light corresponding to the numbers 0-. 9 will light up randomly (the lighting time and interval are also random within a certain range). Press the corresponding key during the lighting period, and 1 point will be obtained. Pressing the light after the light is off is invalid. There are 15 opportunities in total, and the full score is 15 points. The higher the score, the better the reaction speed. You can also exercise your reaction ability through regular such tests.
