I have never heard or seen those games, because in my country and on my side of the world these are not popular. Pusoy looks a bit complex but I raise my attention! Next time I join with my friends I will give it a try and if I like it I will look for a website to play. It is cool to know new card games, thanks for sharing!! 
This is pretty easy and strategies could be a tool to win this game. Others had been twisting already the rules because the cards are just 52 and it is easy to recognize cards that are not yet being thrown or shown to the table.Now, the cards are already fold after it will dispose from a player to avoid thinking of cards that are not yet dispose and check holdings if it could win.
