coan.net: I posted how to play Jump Checkers right on this discussion board eleven posts back on December 8th, 2007
Checkers variants (8x8) (Walter Montego, 2007-12-09 01:42:49)
and some pointers on how to play right after that post. It's an obscure game that I'm sure would not make any lists as you suggest. It first needs to have a few people play it and see if they like it or not. I think just from that post one could program Jump Checkers for this site. IF Fencer has any questions about the play, I'll be happy to answer them.
