Thank you for the reply. I saw those games in the game book, but to me the lesson book (C lesson 34) seemed to imply that there was a long-chain game that you drew an actual circle for like those in the lesson book (C lesson 34) that used 12 marks. That is really what I'm trying to figure out.

I went and took a look at the game book again. Although it does not directly address this question, as it only pertains to a card game, the bottom line is that you can draw a large circle and make 60 marks on it if you want to. Then, use any of the two consecutive numbers from the solution given in the game book to start the chain.

You are exactly right!

Good luck!
