I think that side bets such as Perfect Pair and Big/Small increase the overall house edge in Baccarat. While the main bets (Player, Banker) have relatively low house edges (around 1-2%), side bets often come with higher house edges (typically 5-15% or more). This increases the profitability for the casino. Players should be aware of these higher house edges when deciding whether to participate in side bets, balancing potential higher payouts with the increased risk associated with these bets.
