Various forms of roll your own five-card stud, often with a stripped deck and wild cards, are called Mexican stud, Mexican poker, or Stud loco. One such variant played by the Casino San Pablo in northern California has these rules: 8s, 9s, and 10s are stripped from the deck, and a single joker is added (the deck therefore contains 41 cards). The 7-spot and the J become consecutive, so that 5-6-7-J-Q is a straight. A flush beats a full house (with fewer cards of each suit, they are harder to get). The joker plays as a bug if it is face up, and fully wild if it is face down. The game is played as five-card stud choose-before roll your own. It is usually played with a very high ante, and the high card on the first round pays the bring-in.
The game of Shifting sands is Mexican stud in which each player’s hole card (and all others of that rank) are wild for that player only.
