If a player has done some research on blackjack payouts they know not to play in a game that offers a 6-5 payout. But they see it explained that they are receiving less money and that is the reason not to play in 6-5 payout games.

But there is another reason for avoiding blackjack games that do not offer players a 3-2 payout for their blackjacks: different payouts can actually reduce your blackjack odds.

Not only do you receive less money in a 6-5 payout game, it also reduces your odds by 1.89%. Just because of the change in payout alone.

For players who are fans of blackjack variations, such as games like Super 21, those games also have different blackjack payouts. Most of them, because of the potential—although it is not a great potential—to win a side bet, the payout for a natural blackjack is reduced. In most blackjack variations the payout is only 1-1, or even money, for a blackjack. A 1-1 payout reduces your odds by 2.27%.

A 1-1 payout actually has the worst impact on your blackjack odds of all of the different type of variations.

The reason a lower payout hurts your blackjack odds is because it reduces your opportunity to make money off of the game. Even though you are receiving something for your natural blackjack, it is not what you would traditionally make—that is why it reduces your odds.
