The game rules are real simple.
But because I'm not the best explainer, I'll just give an example
User one - "Okay below user, get ready to play (link to game)
Die 3 times and you loose!"
User two - "Darn, I died three times inside of that game!
Alright below user, taste some of (link to game)
Beat it in 10 minutes!"
and so on. Just link them to a flash/browser game and then give them a challenge, like 3 lives or 10 minutes, etc etc
DO NOT use games you cannot beat, however!
IF THE BELOW USER cannot play the game, then they must wait for their turn to post.
