Quoted from metallik:

Cincy and Ohio league rules on 'odd' games - they can be used, but only if all people in the group agree. Generally the oddballs don't get used, but I think there's at least one big ball bowler match on record somewhere..

Oddball games include:

Safecracker (time based, not number of balls)
Hyperball (gun game)
2 or 1 player EMs (must be played in stages)
Joust/AG Football (if you really want to rank two 2-player vs games)
Bowlers / Gott. SnS
Spinball Jolly Park (software has issues)

I'd put Hercules on the list as well, it's pretty odd.
