Do you miss something on BrainKing.com and would you like to see it here? Post your request into this board! If there is a more specific board for the request, (i.e. game rule changes etc) then it should be posted and discussed on that specific board.
Fencer: Yes that remark was a bit pedantic by mine, but indeed it was slightly confusing as well, because there also exist ways to wrap a board into a sphere (at least I know Spherical Chess), which are just more complicated than building a torus. Of course the confusion disappears when reading the rules carefully.
