I've seen Golf card game rules that call for two decks, but we've only ever used one and it works just fine. This variation is perfect for two players and one deck of cards. I've seen several variations of this game and I will first share the instructions we have been using. The Golf card game, also known as Nine Holes, or Crazy Nines, or sometimes Six Card Golf is a huge hit in our house and so far our family has resisted the shackles of major vice, and I'm guessing yours will, too–no matter how many decks of cards you own.
Those playing cards come in handy when my kid requests we play his favorite new card game, GOLF, 200 times in a row. You should definitely start praying for me because I own about a dozen decks.
My grandparents believed that owning a deck of standard playing cards would tempt the owner into a life of sinful gambling.
