I don't know much about Blackjack, but please consider the following for your Roulette game:

Multiple, configurable saved bets that can be recalled very easily
Right-click to remove mistaken bets from the table quickly (important in fast-paced multiplayer)
One button to remove all bets immediately
Euro-wheel with no 00
A private table option, instead of just public multi-player

I'll be sure to visit with most, if not all of these. :-)

Some of these features keep me away from the currently available roulette games.

Thanks!
