Played the same as Follow the Queen, except it is the card that follows a King that is wild, instead of a Queen.
Follow the Queen:
Standard seven card stud with Queens wild. Throughout the course of the deal, if a Queen is dealt face-up to a player, then the card that is dealt face-up after that Queen is called the "trailer" and it is also wild as well as Queens. These Queens and trailers are also wild in determining who has the best hand showing to open each betting round.
If in the course of the deal, another Queen is dealt face-up to a player, then the trailer that follows that more recent Queen is now the new trailer and the new wild card as well as Queens. The old trailer is no longer wild...in other words, other than Queens, there is only ever one other wild card. Queens and cards matching the current trailer are also wild if they are dealt face-down. Best hand wins.
If no Queen has been dealt face-up after every player has been dealt their four cards face-up, then everybody re-antes and the game is re-dealt until a Queen has been dealt face-up in a game.
It costs a small amount of money for players who are dealt a Queen face-up to stay in the game, and an even smaller amount of money for players dealt a trailer who want to stay in the game (for example, 50 cents for the Queen, 25 cents for the trailer).
