Challenge yourself to a 10-second game. Press the big button to start. Press and hold the big button to toggle between forward and countdown (forward from 0 to 10 seconds, countdown from 10 to 0 seconds). The game begins with a sound effect and the digital display changing to start the countdown. When the timer reaches 10 seconds (or 0 seconds), press the button to stop the countdown and display the final time. Depending on the time, you'll receive four grades: fair, good, excellent, and perfect, accompanied by different sound effects and voice announcements. Come test your reaction time! The 10-second challenge can test a person's reaction time. The stronger your reaction and coordination, the higher your chances of success.
