Yes I was reading about the game. As I understand it, it was played with dice and depending on what card you landed on you'd be moving forward or backward on the board. So negative cards would move you back and positive cards move you forward. You'd have to land right on the anchor to win but if you went one too far and landed on the cross you'd be stuck there until another player landed there to take your place. I kind of want to play
It's a fun game—like the ancient Indian Snakes and Ladders or the modern Shoots and Ladders—and can take anywhere from a couple of minutes to a half hour or more to play as there can be quite a few upsets or stuck places - or you might race right through it in minutes.
You need individual markers, pennies or beans for the pot and for payments during the game, and two dice (dice are available to use online).
It's not just the positive and negative cards that move you as you don't get any benefit from landing on the Sun card (for instance). Some of the card/position instructions seem arbitrary and some have an interesting significance.
I highly recommend playing the game.
As to using a 6x6 layout. Sure, why not? Just be aware that a reader gains a lot by knowing the positions of the layout quite well - so a whole new set of dynamics will have to be developed for this layout that other readers will probably not be cognizant of.
