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” $20 (or so) every hour he/she plays in this game. See 3:2. * 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%.
