Strat-O-Gem (formerly Col-Gems2600) is a Columns / Jewel Master like game for the Atari 2600. Changes:

Saved a bit of code space (and then proceded to use most of it up again–oh well). Most noticeable new feature this version is the enhanced color handling. The wild gems and”bomber gem”now look visually quite distinctive (maybe the wild gems look too cool). I’ve also increased the frequency of three-in-a-row and wild gems.
