KingsRow 1.15a is available on Ed Gilbert's
KingsRow page. Two good reasons
to get it: it plays a stronger game, and older versions will not work with the next release of CheckerBoard.

Once again: Host wanted! I'd like to make my 8-piece database freely available for download on the
internet. If you are able to host it (it's about 2.5GB zipped, and will probably generate
quite a lot of traffic...), please drop me a line! |

Four in a row 3.1: Slightly off-topic, but perhaps you will enjoy this simple game. I rewrote
my Connect Four program; now it looks nicer and plays a stronger game. You can download it on my
4 in a row page |

Martin's computer checkers blog: instead of manually posting and removing stuff here, I have started

The Open Checkers Archive has grown and now contains nearly 23'000 games.
In fact, this happened earlier this year, but I forgot to announce it here.
The OCA is maintained by Hans l'Hoest; Jim Loy contributed nearly 11'000 games to this version of OCA!
Please support Hans and make sure Jim doesn't have to contribute as much to the next edition by sending
in your games. The archive can be loaded and searched in programs that support PDN (like CheckerBoard).
