Hey, speaking of different versions, I forgot to share one that my family made up yesterday. Since one person usually wins (hehe me) we came up with a way to slow me down a little. Normally we start with 10 cards in the Blitz pile. Well everytime someone said Blitz, they had to add one to their Blitz pile in future rounds. This only works well if you are required to say Blitz when empty your Blitz pile. I got up to 14 cards in my Blitz pile. I was still having fun with the added challenge and my family got more playing time and a few more chances to say Blitz themselves, so it was a good idea for us.
