Blackjack bonus bets, like "3 to 2" or "Lucky 7," are additional wagers that allow players to win extra payouts based on specific outcomes or hands, separate from the main game. These side bets are typically tied to events like getting certain card combinations or achieving particular hand totals. While they offer the potential for larger payouts, they generally come with a higher house edge, making them less favorable for players over the long term. Although they don't affect basic Blackjack strategy, they add excitement to the game but often favor the house more than the main bet.
