I play a 4-deck game at Canterbury Card Club here in Minnesota. There is a mandatory rake per hand ($.50 for $3-$25 bets and climbs from there), but there are a number of bonuses that make the game exciting. For example, triple 7's pays 2 to 1, as does 678 and any suited blackjack. Six card hands are instant winners. In addition, three consecutive blackjacks pays $500. I actually hit this last night!
Amazingly, another guy at the table had hit four in a row a couple hours earlier for $1500 (any additional blackjack after three in a row is an extra $1000).
All in all, maybe not the most profitable game (the rake tends to catch up with you), but fun and entertaining nonetheless.
