Another important question is what should be the dimensions of the battlefield?

I'm thinking it should be a 25 inch by 15 inch ellipse. Here's how I determined it:

A regular arena is rectangular with 3 x 4 zones. If you consider each of those zones to be squares with a length of five inches, then the arena is a size of 300 square inches. I used an ellipse calculator and found the area of a 25 inch x 15 inch ellipse to be about 290 square inches, so it was pretty close. There were a number of other dimensions I calculated. 30 in x 10 in ellipse would be too narrow. 20 x 15 I'm thinking would be too small (and too close to a perfect circle. 30 x 15

*might* be okay, but I think it's too big. Maybe it doesn't matter though, since both 30 in x 15 in ellipses and 25 in x 15 ellipses are pretty much equal to 2 square feet in area.

Also, having a 25 in by 15 in battlefield would probably work for both 1 on 1 games and 2 on 2 games.

Of course, if you really want flexibility in the number of players playing, such as for four player free-for-alls and the like, it might be better to go with a circular board that can increase or decrease in size by unfolding outward from the center or something. I think it would need layers to do that though. Like an onion shaped board. And depending on how big you want the battlefield to be, you peel a layer and lay it flat on the table.

Or, it might be better to have a single flat circular board around the size of about 150 square inches (radius is about 7 inches). This is the apprentice mode board. Then you could encircle the board with a "ring" that has an inner radius of about 7 inches and an outer radius of about 10 inches. The apprentice mode board has now transformed into a regular (300 square inch) 1 v 1 board. Add another ring with an inner radius of 10 inches and an outer radius of 12 inches and you get a 3 player free for all! Add another ring of inner radius 12 inches and outer radius of 15 inches. Now you have a 4 player game of 600 square inches!

I did my calculations using the google calculator/unit converter and these other two calculators, this one for the area of ellipses:

http://www.ookingdom.com/metric/diameterI used significant figures for my calculations, so there were multiple times I had to round due to uncertainty in measurements. I suspect, however, that each ring has an outer radius of exactly 1.5 inches greater than the next size down (not entirely, since I excluded 3 player apprentice mode, and 4-player apprentice mode would use the same sized board as 2 player regular; for those who are curious, I had the radius for 3 player apprentice mode board as 8.45 inches).

And about my last post that I deleted...I apologize for that. I got confused and used the wrong conversion factor for turning square inches into square feet. I should have multiplied by 1/144, rather than by 12. It was awfully stupid of me, and it went completely against common sense. Sorry if it scared anyone when I said that we would need over 100 square feet for a board if a range of 5 inches was the equivalent of 1 zone length. That is obviously NOT true. I can't believe I said that.

I swear I'm not crazy!
