I have a suggestion...leave the game board full, but change the rule to fix the leapfrog-land-grab loophole. That way, the player with the most squares can't gain any more, and other players can take squares away from him. The board will then redistribute over time so that everyone has a share of it.

I find I'm starting to like the Paint aspect it has now.

This will involve voting against the CFJ, BTW. And I'll let someone else propose the loophole fix.
