You know them: those games you played somewhere, once, but never saw again.
Here are a few...
Red Clash.
Snap Jack.
Jump Bug.
Bosconian.
Cuber- Not even the Killer List of Videogames has this one!
A truly bizarre Space Invaders-type game which involved a grinning elephant head on metal legs and silver rings that grew unless you shot them.
Firebird.
