When I was young, my family would always play, with real money in the pot, Pusoy or Pusoy Dos (it's a variaton of poker) while waiting for the clock to strike 12 on Christmas Eve. Then we do "Dealer's Choice" and everyone gets to choose or invent a game and its rules. Mostly we come up with ridiculous variations (that happens when you're drunk) such as black jack where any red card = zero, or forced high lows (if you decide to quit in the middle of the game, there's a big fee to pay so you end up playing until the end, unless the raises become higher than the quit fee). Then there are side bets like you pay a certain amount for every point difference you're lower/higher than the cards of the person to your right. Or stupid rules for poker where you're to pass one of your cards to the one on your left just before the end of the game. lmao
That was fun to do, if you don't mind wasting your money for laughs.
