Here is the other interesting game, now that it is complete:

Frog Finder (grillyx vs. coan.net)

B2 is actually a 5 box! (If I had an extra move before losing, I would have taken it to show the "5", but had to guess quickly before losing)

5 box - 4 of my own, and 1 of my opponents hidden in there - making it really hard to find without giving up my own!

Now to find a "6 box"
