 Congo

Congo by Demian Freeling (around 1980?)

Congo is a well-known chess variant which can be played on Christiaan Freeling’s beautiful MindSports Arena website.  The redoubtable Richard’s PBeM server also supports Congo, and Zillions of Games now supports it..  I refer you to either site for the rules and history of the game (Demian Freeling is Christiaan Freeling’s son, so the presentation at MindSports is surely definitive); I include it here because I made a beautiful Congo set and want to show it off.

The pieces are Giraffe, Monkey, Elephant, Lion, Crocodile, and Zebra.  I found the animal figures in children’s toy sets, but I had to buy many sets to get enough of all the figures I needed.  The surplus animals I gave to a day-care center, so I didn’t look on it as wasted money.  To give the figures a gamepiece look, and distinguish the two armies, I wanted to attach them to a disk-shaped base that could be colored white or black.  For this I used the caps that came on bottles of cat litter.  The bases for the black army I painted with model paint.

The hardest part was attaching the animal figures to the bases:  no glue would hold them.  I finally used a pushpin to poke holes through the plastic figures’ feet, and through the plastic cap near where those feet needed to be mounted.  Then I tied down the animals with clear nylon monofilament fishing line, threading through the holes in the cap, and fixed the knots with epoxy on the underside.

Finally I poured plaster of paris into the caps to give them weight, and cut circles of adhesive felt (from the hardware store) onto each piece’s underside.

The board itself had to be pretty large to accommodate the pieces.  I used black foamboard and glued squares of colored paper onto it.  I had to make it in two unequal pieces (the board being 7x7, and 7 being odd).  Too bad I’m not a woodworker!  I chose to use different coloration from the MindSports Arena standard, with blue to suggest water, green to suggest jungle, and orange to suggest the Lion’s domain (savannah?).
