Introduction
The number one casino game in the world is a bit of a mystery to many American casino-goers. Baccarat traces its history to the gambling salons of Italy and France, but within the past thirty. Look for Fewer Decks. Baccarat isn’t a game like blackjack or roulette, where rules can make a big difference. But one positive rule that you can look for is going from 8 decks to 6 decks. A standard 8 deck game features a 1.06% house edge. A 6 deck game offers a 1.056% house advantage. Let’s look at how this can make a difference in the.
I've been getting asked a lot about the odds in baccarat for unusual numbers of decks. To hopefully cover all my bases, this page shall show the number of combinations, probability of winning, and expected return, for every number of decks from 1 to 12.
Combinations
The following table shows the number of combinations for all three possible outcomes by the number of decks. The combinations in this page get pretty huge. Unfortunately, Excel displays only 15 significant digits, so please don't write to me that I'm wrong after 15 digits. Instead, please blame Microsoft.
