Opens a terminal console (for Java?), followed shortly by a game board and two or three primitive dialogs. There is a speaking voice inviting you to a game of checkers. Unfortunately, game play is a bit buggy -- at least, in my case, play halted when the program marked a forced move in the middle of the board with no close checker to make the move!
Needs work. A pity, too, because at first blush this is a nice, free checkers program -- welcome in a world where the "free" XP software is usually embedded in adware and/or other annoying commercial sludge.
