Auto game end
Leave the game at the screen after Regis asks "How many players there are?". Regis will eventually get mad and end the game.
Easier game
Do not enter a name and wait for Regis to get mad and enter a name for you. It will then be easier for you to win a million dollars.
Harder game
Enter WILL VALDEZ as a name.
Imposter
Try naming yourself as DAN BLONSKY and you will be renamed as IMPOSTER or PHONY or FIBBER.
More Funny Regis-isms
Enter your name as Millionare. Regis will make a silly comment and change your name to Dreamer. Oh my goodness, does the comedy ever stop?
