I find it best to do play a game, only STOP PLAYING before you get tired of playing the game. Just when you realize how much fun you're having, stop playing and get back to work!

Or you'll just play the game until the game burns you out.

This is a good point. I have a similar system with reading books. I only allow myself a chapter or two, and I’ll still want to keep reading it when I get back to work, so the reward mechanism is still there.
