6:5 Disadvantage

What is the overall disadvantage in a game that pays 6:5 for naturals? Is it -1.41% ?

Normally you would expect to get a blackjack every 21 hands (more or less). This bet pays 1.5 for every 1 you bet. With 6:5 it only pays 1.2 for every 1 you bet. Thus you are sacraficing .3 units for every 21 hands (21 units bet). .3/21 = .014285 or -1.43% for this rule alone, added on to whatever else the casino edge for the particular game is.

Standard disclaimer: I make mistakes.

I don't think you factored in ties. It would be slightly different based on the number of decks in play, but for the single deck game, where this is currently found, I think it comes out at around 1.39%. Either way you cut it, this is a lousy rule and it is a pure sucker's game. Of course, that is just what the casinos love.

Do they offer "even money" in a 6:5 game? Unlike a normal game, this would pay better than insurance, but I would be surprised if they could get away with not offering it. Fortunately, I have not seen any 6:5 games in person, so this is just a theoretical. Assuming that I am not confused on this, would this change the index for even money (different than the insurance index)?

There are several places that "offer" 6:5 on the Strip now, such as Aladdin and others. It's for those products of our great public education system who think that it's a better deal because 6 is obviously more than 3 and 5 is more than 2.

I've seen 6:5 on the multi-deck games at Aladdin, Paris, et al. as well.

No, they don't offer the "even-money" version of insurance if you're holding a natural. The house treats it as a push.
