The Multi-Bingo is really taking shape.  I discuss some of the difficulty in introducing bugs that are unexpected when thinking about the reset sequence of the EM games vs. a solid state. Today's year of flipperless game is 1934's Exhibit Golden Gate. Golden Gate has an interesting middle playfield feature that allows for high scoring if you land balls in the 'open gate' hole. You can also return 'Out' balls to play by hitting a different hole. Fun looking machine with an interesting gimmick. http://ipdb.org/machine.cgi?id=1048
