In 1963, Ted Zale designed a fascinating game called '3-in-line', based off of the bingo gameplay, but in a flipper package.
Ther eis a 9-digit bingo card in the playfield and backglass that lights as you hit various targets on the playfield.
Some neat swinging gates allow entry to the left and right pops.
I love that the flipper division made a game marketed to bingo players at the height of the bingo market.
