Line-Up was Bally's first attempt at a bingo-style pinball machine.
25 holes arranged in a grid on the playfield in the same arrangement as the card on the backglass (1-5, 6-10, etc).
Due to the extreme spacing between numbers, it looks very difficult to actually win on this machine. Couple that with the fact that balls do not return to the player when they reach the bottom, and you've got a very player-unfriendly machine.
That said, I'd still play it.
