Louisiana Lo-Flop is a poker variant that, unlike its name might imply, features neither a flop nor lowball play.
The way it works is that each player antes and then is dealt two cards facedown. Each player may look at only one of their cards. Higher cards are better. There's a round of betting, then every participant gets the opportunity to switch the card they are playing from the one they have seen to the other unknown card. If they do so, they pick up the second card, and the original card no longer plays.
After a second round of betting, showdown takes place, and the highest card wins the pot. In case of ties, suits come into play with the following ranking: spades (highest), hearts, diamonds, clubs (lowest).
