The game of Duchess^TM, invented by Alan Blair and John Kramer, was first played on November 28, 1984 in Pacific Palms, Australia. The board design (below) was finalized the following year and the rules were refined after extensive game-testing with the help of Mike Blair and Warwick Hooke.
We are looking to manufacture a physical version of Duchess^TM in wood or plastic, based on this cardboard prototype. You can also make your own board and pieces with cardboard and a printer.
