Commercial chess variant on a 10x10 board with two non-royal kings added.[All Comments] [Add Comment or Rating]Greg Strong wrote on 2017-10-22 UTCOmega Chess had commercial sets. They don't appear to be available right now, but it says "new boards coming soon." And House of Staunton has variant pieces for Muskateer Chess. There have been many, many commercial variants over the years, but they almost invariably go bust. There's just not much market for it. It's impressive that Grand Chess and Omega Chess have held on as long as they have. If you can find a copy of Pritchard's Encyclopedia of Chess Variants, it is filled with commercial variants that are long gone.
