Any particularly interesting games for a 42S/DM42/Free42 or older models?

The other day, I adapted the HP 25 Bomber Raid game in here for my DM42, plus a 41C golf game that I can't recall where I found. They're both pretty good little mental exercises for killing 5 minutes.

What calculator games were notorious for distracting students during dull lectures back in the '70s and '80s? I'd be interested in programs for any models prior to the 42S, or even for TIs, since it's usually easy to adapt them to the 42 (and often make them a bit shorter by replacing random number generation routines with calls to the built-in RAN function).
