Adding a timer to a game

I created a game. It's not a quiz, but i tell the users they have 60 seconds to complete it. How do i create a timer with 60 seconds to add to the slide. if they finish within the 60 seconds then their fine. it takes them to a new screen. If they run out of time I will give them one more chance. if they run out of time a second time it will direct them to another screen that basically says they failed.

Any and all help will be appreicated.

Thanks!
