I came across this variant while browsing in BoardGameGeek.com .
The idea of it is to play chess with out a board. The Chess pieces are
represented by tiles that must, at all times, be connected to each other.
(According to that page, it's a cross between Chess and Dominoes.) The
Game allows up to six players to play.
Is there a page for this game here? It certainly sounds like a crazy idea.
