Yes, you can play Blackjack at the same table with friends, as long as there are open seats available. However, keep in mind that you're all playing against the dealer, not each other, so the goal is still to beat the house. While you can sit together and enjoy the game, your friends' actions (such as hitting or standing) can affect the flow of the game and the cards available, which might influence your strategy. It's common for groups to share a table, but be mindful that the outcome of each hand is independent of others at the table.
