Three great programs
BGRoyal n is a nicely designed freeware Backgammon game (see Screen 4.) The program, which was written by Chris Emsen, allows you to choose to have the menus displayed in English, French, or Dutch.

BGRoyal is a Backgammon game that works nicely on the palmtop.
Blitz Draughts n is a shareware DOS-based checkers game that works well on the palmtop. If you thought checkers was a simple game for children, think again. The documentation file says that, "You will need to be a very good player to beat BLITZ, even on a very low level of play."
Riziko is a shareware version of Risk, the popular board game of world conquest. Written for the palmtop, this program has some amazing graphics.
