If you are willing to translate it to a different language, I will make it available on this page. Please mail me for more information.

This version of 2.2 can be installed (preferably) right over a previous 2.2 version, that way your preferences are not lost. The most significant difference with DAM 2.1 is the facility to play draughts with another player over the Internet, using the DamExchange protocol written by Frank Mesander. I welcome email about your experiences with this version, and any suggestions for the next version. Please send them to hjetten@xs4all.nl.

For those who prefer Windows 3.1x, the 16-bit version DAM 2.1 will of course remain available: download dam21.zip (195 kB). In case you don't have a sound card, it's likely you can still enjoy the DAM sound effects with the Windows PC speaker driver, and the mono version of the DAM .wav files.

Endgame databases

An endgame database allows DAM to quickly look up whether a position with a few pieces on the board is either won, drawn, or lost. That considerably improves its playing strength in end games. Starting with version 2.2 v.5, DAM can handle 5- and 6-piece databases. If you wish, you can generate them yourself using DragonDraughts-0.0a.Win32.zip (thanks to Michel Grimminck).

New! All DAM 2.2 endgame database files can now be downloaded from here.
