How does the number of decks affect the dealer's chances of busting?

How deck number affects dealer bust odds:

• Fewer decks: Higher bust odds. Removing cards has bigger impact, so more likely dealer draws high cards that bust.
• More decks: Lower bust odds. Less card impact, so less likely dealer gets high cards that bust. One card matters less with more cards in play.

While dealer's bust odds don't change fundamentally by decks, they do change based on how deck composition and card impact differ by decks. The probabilities of dealer getting bust cards change with card removal effects. Fewer decks means more sensitive probabilities and higher bust odds. More decks means less sensitive probabilities and lower bust odds. So adjust your strategy based on the dealer's bust odds by decks.

In addition to the above, there are a few other factors to consider when it comes to how the number of decks affects the dealer's chances of busting.

First, with fewer decks, there is an increased likelihood of the dealer busting due to the heightened impact of card removal on the remaining deck. This is because, with fewer cards in play, the removal of even one card significantly impacts the composition of the remaining deck. For example, if a single deck game has a lot of low cards removed early in the game, it becomes more likely that the remaining cards will be higher and increase the likelihood of the dealer busting.

Second, with more decks in play, it becomes more difficult for card counters to keep track of which cards have been played and which cards remain. This can result in a higher house edge and lower player advantage, as it becomes harder to make informed betting and playing decisions.

Lastly, it's important to note that the effect of deck size on the dealer's bust odds is not uniform across all rule variations. For example, a game that allows the dealer to hit on soft 17 will have different dealer bust odds depending on the number of decks in play, compared to a game that requires the dealer to stand on all 17s. It's important to consider all the rule variations when determining the effect of deck number on the dealer's odds of busting.

The likelihood of the dealer busting in a blackjack game can be impacted by the number of decks being utilized. In general, the dealer's chance of busting increases with the number of decks. This is why there are more valuable cards concentrated in fewer decks.
