Multihand Blackjack Pro 2 supports five main betting boxes, each with optional Perfect Pair and 21+3 wagers. The Increase Bet control doubles placed chips before the deal, while Double Down is a separate in-hand action that adds one final card. Confusing those two controls changes the meaning of a rule explanation. Optional hints, Rebet and Turbo affect interaction with the digital table. Each player's hand competes separately against the dealer's single hand, rather than sharing one combined total.
