WARNING: DANGER AHEAD
Don’t play casino twenty-one when the dealer only pays 6 to 5 on a blackjack! Unless, of course, you can see the dealer’s hole-card.
Norm Wattenberger, author of Casino Verite, sums it up nicely – “If a casino calls a game Blackjack but in small letters says Blackjack pays 6:5, it is a fraud. You should not play 6:5 Blackjack. In my opinion, you should not play any Blackjack at a casino offering this fraud. You should not gamble at all in such a casino, or stay in its hotel or eat in its restaurants.”
6:5. Abbreviation for a blackjack game in which naturals pay off at 6 to 5. This is a sucker bet. A $10 wager will win only $12 if the player receives a natural and the dealer does not also have a natural 21. House edge for a typical single deck game with the 6:5 rule is about 1.45% *, compared with 0.18% for a typical single deck game with the normal 3:2 rule. This is a definitely a rule all players should avoid and protest. A typical $25 player will lose an “additional” $25 to $30 (or so) every hour he/she plays in this game. See 3:2. See rule variations. * Note: In some 6:5 single deck games, a player’s natural wins regardless of what the dealer has — which reduces the house edge in the game slightly to 1.24%.

6-7-8. A popular bonus hand in social blackjack games and in some casinos. Some casinos have experimented with paying players a bonus if they receive this hand suited but only if they win the hand. In other words, the player does not receive the bonus if he ties the dealer or the dealer turns up a natural. Typically, any 6-7-8 pays double or there is a bonus for this hand. See Royal 21. See 7-7-7.
