DEFUSE24

Defuse24 is a very simple yet addictive puzzle game:
A bomb will explode after 24 seconds. As a bomb-disposal expert, you must constantly calculate the numbers on the timer to reset it back to 24.
Once you start the game, you will not able to quit unless the bomb explode. Pause the game only available before 20, after that will cost you life.
