So is Pineapple just where Texas and Omaha meet? Not exactly, with Omaha you are dealt four hole cards with the requirement that two must be used in your hand. With Texas Hold'em and Pineapple, there is no such requirement.
The "deluxe" of Pineapple Deluxe is that the final community card, the river, is wild and makes the three other cards of the same value wild. The extra hole card inherent to Pineapple allows for better than average Hold'em hands. The four wild cards, one of which everyone has, makes any hand less than a full house a likely loser. If you play this abomination of poker, don't feel confident without four (or better yet five) of a kind or a straight flush.
