Side bets in Blackjack generally increase the house edge, making them less favorable for players than standard play. While offering the potential for larger payouts, these bets typically have much higher house edges, ranging from around 4% to over 10%, compared to the 0.5-2% in basic Blackjack. Casinos introduce these options to boost profits, appealing to players seeking bigger wins. Although occasionally offering theoretical player advantages, side bets usually erode bankrolls faster. Players focused on optimal strategy often avoid them, but some make occasional side bets for entertainment, accepting the higher risk.
