The optimal number of decks for blackjack generally favors fewer decks. Single-deck and double-deck games offer the lowest house edges, around 0.17% and 0.38%, respectively, when using basic strategy. These are ideal for players looking to minimize the house advantage. However, casinos tend to offer fewer single-deck games, and card counters can exploit these situations more easily. As the number of decks increases, such as with 6 or 8 decks, the house edge rises slightly to around 0.5% or 0.6%, and card counting becomes less effective. Therefore, if you're aiming for the best odds, fewer decks are typically better, but the choice also depends on the game rules and whether you plan to use advanced strategies.
 
Absolutely, the number of decks used in a blackjack game is a crucial factor that impacts the house edge and players' chances of winning. Single-deck and double-deck games are known for their player-friendly odds due to the reduced number of cards in play, making it easier to track the cards and make strategic decisions. As you correctly mentioned, the house edge in these games can be as low as 0.17% for single-deck and 0.38% for double-deck games, assuming optimal play.

However, as the number of decks increases, the house edge also tends to go up. In games with 6 or 8 decks, the house edge typically hovers around 0.5% to 0.6%, making it more challenging for players to gain an edge over the casino. While card counting is still theoretically possible in multiple-deck games, the increased deck penetration and shuffle frequency can negate the advantage gained from counting cards.

When choosing the optimal number of decks for blackjack, players should consider their objectives. If the goal is to minimize the house edge and have a better chance of winning, single-deck or double-deck games might be the way to go. However, availability and game rules are also essential considerations. Players should assess the overall gameplay experience, including factors like the table minimums, payout ratios, and any additional rules that may impact the odds.

In conclusion, fewer decks generally offer better odds for players in blackjack, but it's essential to weigh this against other game factors and personal preferences. Whether you're a casual player looking for entertainment or a serious strategist aiming to beat the casino, understanding the impact of the number of decks on the game is key to making informed decisions at the blackjack table.
 
As more decks are used, the house edge grows. For instance, with ideal play, a single-deck game may have a house edge of about 0.17%, whereas a six-deck game may have an edge of more like 0.6%.
 
As the number of decks increases, particularly in games with six or eight decks, the house edge tends to rise, making it more challenging for players to effectively count cards and follow optimal strategies. Thus, while the ideal scenario is a single-deck game, players should also consider other factors such as table rules and conditions to determine the best choice for their play style.
 
However, many casinos use multiple decks to reduce the effectiveness of such strategies. While the specifics can vary based on the house rules and player strategies, a game with two decks is often seen as a good compromise, balancing player advantages and house edge, while still being manageable for card counting.
