The gist is that you each start out by casting on 10 stitches and knitting a couple of rows. You then answer questions or perform challenges in order to earn the right to knit more rows. Sometimes, though, you're penalized by having to rip out some of your rows. The questions range from very easy to kind of obscure, so you never know how you'll do. Some of the challenges involve knitting as fast as you can, or in my case, trying to knit with your eyes closed. Other challenges are actually little word games. Sometimes, it's just pure luck who gets to add rows and who loses them. The person who has the most rows knitted at the end wins!
We played this impromptu, so we used random needles and yarn that we had on hand. For me, that was sock yarn on largish needles. If you're planning to play, I'd recommend at least worsted weight yarn--something easy to see, easy to knit, and easy to rip!
Muggles will not "get" this game at all. I know because I tried to explain it to my husband, LOL! It's definitely something fun to do with your knitting friends, though. The limitation is that after you've gone through the finite number of question cards after a few games, you'll all know the answers. However, we talked about how it'd be fun to then come up with your own questions and challenges, and I think that'd be a great way to keep it going for future gameplay!
(In case you're curious, no, I was *not* the last knitter standing! I did come in second though!)
