Please Give some suggestions about the new betting and gambling functions added to CHA!!!

From magician:

Venetian and I are going to have a discussion about what games and betting functionality to add next, based on all the feedback we've received.
what's your favorite method of sports betting? what existing site is a good example of the style of betting Chancecoin should implement?
and for regular casino games (blackjack, roulette, pai gow, poker, etc.), which ones do you think are most important to implement?
I g2g, but if you guys get a chance to answer those questions, I'll check the responses later.
