Bonanza

Here is a 40 coin maximum version of the Magic Squares game type, but Bally got rid of the extra balls and have red/yellow/green/blue colored lines instead of the original red/yellow or red/yellow/green.

In addition, the center vertical line of the card could be moved up/down one position.

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 wheels have 4 numbers mounted on each. Here is the standard layout for magic square A. The first table shows the "home" position of the numbers, and the second table shows the numbers rotated one position:

The 4-number squares were initially used in the corners of the card, so people also called the feature "turning corners".
