Mini Game Problem

I coded the game Pong on Scratch and I am wanted to transfer it to Snap. In my game on Scratch, every time the ball touched the red boundary, I made the player press the green flag to start the game over. My game in Snap has an intro, so I can't make them press the green flag to start the game over again, or else the user will have to wait a long time to get to this game. How can I make the game pause for only a few moments and then start over again?

The WAIT block? And then, I don't know, start the game script with WHEN I RECEIVE [GO] and then after the wait you can BROADCAST [GO].
