Following after Venice, London returned the payout for four star numbers to 300/600, and changed the special game rules.

In this special game, each of the holes on the playfield had a symbol under it: a triangle, square or circle.

The player is required to get one of each symbol, in any order, with the first three balls shot. If successful, you can stop and take your payout before shooting another ball. If you choose to go on, you can shoot the next ball for triple-or-nothing by making the symbol flashing on the backglass. If successful again, you can try for another triple-or-nothing on the 5th ball. Max payout for the special game was 432.

London also introduces the twin number feature. 17/18 and/or 11/19 could be lit on the backglass. Making one of the pair lights both on the bingo card. Twin numbers did not affect the special game. If both twin numbers were hit, and all three extra balls obtained, you could light ten of the twenty numbers on the bingo card.

First appearing on Border Beauty, this new game type took the section scoring idea from the magic screen games and got rid of the in-line scoring that had been on every bingo up until now.

While they were at it, they removed five holes from the playfield, and decided four colors (red/yellow/green/blue) were better than three.

The nasty trick was that one number in each color group was white with a corresponding colored star. That number counted as the fifth number in the color only, otherwise it only counted as a lit star. (e.g. the four blue lit plus the blue star would pay 5-in-blue. Two blue lit plus the blue star is worth nothing).

So you really have five balls and you have to get at least three out of four in the color to win.

Unlike the magic screen games, the color sections were stationary and you moved the numbers behind the metal panel that had the color pattern painted on it.

The main card is 4x5 (four rows, five columns). The center column was a Magic Line - it could be moved up or down one position. The two columns on the left could be swapped with themselves, and so could the two columns on the right.

Keeping in mind the popularity of the OK game feature, they added this as a standard item on almost all mystic line games, and called it the Red Letter Feature. 3 or 2 balls in the star numbers would award the red letter game.

In addition, all mystic line games had a 3 or 4 star numbers score some fixed number of credits.
