ADDUP is AddUp v.1.0 by Dave Henry.  This game is another version of
Columns, but with a twist.  Blocks fall in groups of three. The object is
to make 3 consecutive blocks add to 15 in either a horzontal, vertical, or
diagonal row. When this occurs the blocks dissolve and any remaining
blocks above fall downward. The second objective is to avoid 3 consecutive
blocks that add to 14. When this occurs the blocks are marked with X and
cannot be elimated from the game.  Keyboard controlled.  High scores are
stored.  Docs included.  Color only.  This is a wonderful game that makes
you think, and rewards you for quick math skills.  It gets harder as you
go on!
