The Reshuffle feature comes into play when a player folds. Their cards are swiftly reshuffled back into the deck.
This means that the next player only gets to see their hole cards when their turn arrives. Please note that due to the workings of this feature, pre-action buttons (e.g., “fold”, “call”, “raise”) will be disabled for games using the ACR Poker Reshuffle feature.
Optically, it will appear as if all players have been dealt their cards simultaneously just like all other games, but in fact players will be dealt their cards one player at a time starting at with UTG +1. The next player will be dealt his cards only after the first player has made a preflop decision.
