Since Blackjack is basically a 50/50 game, each players' chance to win is equal to every other player. Also, since all bets are equal, your return on a winning hand is equal to your risk (7 players -- odds of winning = 1/7, return = 7/1) EXCEPT for the house rake. Therefore, it is a losing deal by whatever the ratio of rake/bet is.
I would avoid like the plague.

Why doesn't AZ wise up to the fact that Blackjack odds are FAR more favorible to the player than the slots, and allow regular house backed games?
