Double Header
Double Header is a fairly hard game to come by...I know of four ot five in existance. It certainly gets the prize as the most unusual bingo. The success of the Magic Square feature had Bally chanting "more of the same", but there was that crowd of old bingo players that like the old machines with the select-a-spot feature.Bally's solution? - stuff two separate games in the same machine. They share a playfield, but that's about it. The player could choose to play either game, or both at the same time!
Game 1 was a single card, select-a-spot game with colored lines multipliers. The multipliers were double on the red/yellow horizontal/vertical lines, and triple on the green diagonals. The select-a-spot numbers were split into three groups as separate feature levels: 12/14, 2/5, 15. The higher the feature level you got, the more groups you could pick from. Hole #15 was on the center of the card, breaking the tradition of the center being hole #16.
Game #2 was a basic magic squares game with no colored line multipliers, but up to four numbers could be spotted. I think any other magic square game offered better payout chances.

Some of the numbers on the bingo card are are mounted on wheels (behind the backglass), and pushing buttons on the foot rail allows you to rotate the wheels to rearrange the numbers into paying combinations.
| A | 1 | 9 |
| 19 | 4 |
| A | 9 | 4 |
| 1 | 19 |
The 4-number squares were initially used in the corners of the card, so people also called the feature "turning corners".
