Test your brain by tapping the screen when the timer reaches the correct time.
There are four game modes:
Classic: A random time is chosen and you must stop the timer when it hits that time!
Blind: A random time is chosen and you must stop the timer when it hits that time but the timer disappears!
Reflex: A random time is chosen but you do not know the time and must hit the screen when you see a change!
Hold & Release: A random is chosen and you must hold the screen and release when the timer hits that time!
Stop the timer at perfect second!
