Oh I thought you wanted to play with current implementation, people being responsible for following the variant's rules... which is possible for Euler LOA only.
I've played a few games now of the Black Hole variant, which appears to be the standard version of the game on LG. It's fine. However, the black hole appears to me to be an unnecessary complication of the very elegant original rule set. I understand the internal reasons on LG for increasing the size of the board. I also understand a mechanism like the black hole in order to restore some symmetry on a board with an odd number of squares on each side. Why not move straight to 10x10, without a black hole? Has anyone tried this variant?
