Pineapple is a variation of Texas Hold'em, with a key difference in the number of hole cards dealt and when players must discard a card.
Hole Cards: Players are initially dealt three cards instead of two.
Players keep all three hole cards during the pre-flop and flop betting rounds.
Before the turn card is dealt, each player must discard one card from their hand, leaving them with two cards to play.
Other than the unique discarding rule, all other rules and betting structures are identical to Texas Hold'em.
