Three games, BlockAttack, flCheckers & flSudoku, statically compiled with fltk. Run from Menu>Fun.

The games work fine on my Dell Latitude D620 running Slacko 5.7.0.

Thanks Much

Excellent checkers game, muggins. Thanks!

Very configurable, with a setting for "intelligence" of the computer opponent, predictions of upcoming moves, and most important: Undo.
