That sounds like a challenging game. I guess it only works when a Q is flipped up on the board.
I remember my first years of playing cards, other than canasta at 12 years old, when we use to keep jokers in there and call jokers and deuces wild. That would be in 5 card draw and sometimes 7 card draw poker games.
Being teenagers, at times we would take turns calling which cards would be wild in the next hand. Most of the time the jokers would be taken out so we would have more wild cards. Other times just leave them in to have two extra wilds on top of the 8 that were already called. We had plenty of 5 of-a-kinds during those rounds.
It was fun to play those kind of games when you are just learning.
I guess a game can be a bit more challenging during a stud game and if there were only one card that came up to make the next one wild.
Lucky next person who follows the Q.
