Hi amigadave-
I can't believe that nobody added Freecell to your list! I know it is a PC giveaway/standard, but the port to amiga (from aminet I think) looks good and has multiple take-back-move levels. Sometimes heavy duty backing out of a bad strategy will crash my machine, but it works well enough to be a good learning/training device and has upped my overall percent to the mid 80s.
I love Galaga, Pinball, and Megaball, but Freecell is the one that forces me to play one more game. Part of the addiction is that a game is over pretty fast, so you can play in between doing other things without feeling guilty about "wasting time".
Yours-
CRL
