Advancing odds changed that. You can maybe increase the number of credits you can win by depositing more coins/credits before shooting the first ball (and sometimes after the first ball, on games with the stop and shop score booster feature).

A typical 3-in-line payout on an early machine with ten odds steps would be:
2 4 6 8 12 16 24 32 48 64

The first coin inserted would reset the machine to the 2 level, successive coins would increase it zero or more steps. Zero is the main reason the machines are considered gambling devices in many areas. You can deposit a coin and the odds may not increase (at least they never get worse, like on some early one-ball machines).

In the late 70's in a effort to distance the games from legal definitions of gambling devices, the advancing odds feature disappeared again on some machines. In addition, there were a few games made between 1956 and the late 70's that didn't have this feature either. These games were usually for territories where standard bingos were illegal.

See the Safari flyer.

The location owner has access to one, and the operator the other. The idea was to have the game automatically split the take (and to some extent allow the location to recycle coins without needing to get into the main cash box).

The split was adjustable from 1/1 to 1/5.

The ballyhole was also used to light features automatically for the NEXT game played, like enabling all the magic squares.

Later screen games just paid a fixed amout:
- 3 in blue scores 200
- 3 in blue scores 600
- 2 in blue scores 600!

The idea was to give the player a way to bump the ball off a post/spring without risking tilting the game.

It was only used on Hi-Fi.

When colored lines were added, though, it became more important how the in-line score was formed on the card. For example, 3-in-line on a red line could be worth more that 3-in-line on a yellow line.

On many games where you could rearrange the numbers/sections, the colored lines/sections scored independently, so you could often get a 3-in-line in yellow, then rearrange to score a 3-in-line in red using the same numbers and get paid for both wins!

On a couple games, the "corners" were a little unusual, but the concept was the same.

On Miss America games, sometimes sliding the magic lines would put the same number twice on one card, and on Miami Beach and Parade, opening the curtain/extra lines would reveal multiple instances of the same number.

You could either take your payout, or you could try for double-or-nothing.

When attempting double-or-nothing, sometimes you played another game (usually three ball) with a specific objective, or sometimes the machine just made a few noises as it generated a random result and then paid you double or zip.

The gotcha was that if you made one color 2x, you would make another color 1/2x.

Extended time allowed the player to moved/spot numbers after the fourth or after the fifth ball was shot, so it was possible to arrange the numbers for the highest win.

Extended time was often tied to rollover buttons. The left rollover would enable after-fourth, the right rollover would enable after-fifth.

Note that the rollovers themselves were features that were not always enabled, but had to be bought at mystery intervals using coins/credits.

The likelyhood of getting extra balls decreases as the payout odds/feature levels increase, and getting successive extra balls is less likely than getting the first one.

In some games, it's actually impossible to get an extra ball 50% of the time if certain features are lit!

The futurity feature allowed you to accumulate OK games in an additive fashion until you got to the maximum game. The futurity count on the backglass displayed a number between one and twelve. The orange section award on the magic screen would add 1,2,3,5,9,or 12 to the futurity count. When you can get the futurity count up to 12, then you can play the machine with practically everything enabled, all odds at/near maximum, extended/extra time/play at maximum, etc.

Unless you are really unlucky, you should rack up a huge payoff when finally playing your futurity game.

The rebound rubber could be lifted up so the ball would pass beneath it and then deflect sideways out across the second row of numbers on the playfield, letting you bypass holes 1-6.

"Gate" was also used on the backglass to describe the purple section on Golden Gate and Silver Sails.

The golden game is a special no extra ball possible game similar to an OK game, but rather than shooting balls for the usual in-line scoring or section scoring, you are limited to a magic screen that only has gold colored sections.

You need to put either two or three balls in the same section to win a payout displayed on the backglass.

This was implemented using offset holes in the shutter panel where the panel would slide up and sideways to release the correct balls.

It's a pretty neat feature!

A couple games also included some extra 3-in-line and 4-in-line diagonals, and a few games also had 6-in-line scoring on 3x6 (18 holes) or 4x6 cards (24 holes).

The other major scoring style is section scoring.

Ok, what that means is there is a switch on the side of the cabinet that can be turned by a key. Every time you closed the switch, one credit is added to the replay register.

It's pretty handy if you don't have the machine "misadjusted" to allow free play, as you can quickly add credits to the game without putting in coins.

When the games were operated, it was supposed to allow you to take your winnings in the form of an IOU. When you came back at another time, the location could put your credits back on the game using the key.

There was an interesting other use. Many late model games restricted the total number of coins you could insert into the machine for one game, but there was no restriction on the number of credits you could play. So instead of putting in coins, toss the bartender some bills and let him put the credits on, then you can play as many as you want per game.

The standard in-line scoring pattern was displayed on the backglass, but the card behind it is actually 5x16 big. You are only seeing a 5x5 view of it. You score in whatever 5x5 view you push the R-button in.

The same number may appear more than once on a card. The marketing people dubbed this double duty numbers.

It is actually a magic screen mechanism that has the numbers attached to the screen panels. The purple highlight in the pic is the viewable area.

Miami Beach was the only machine to use this concept as the main feature of the game.

The numbers on the bingo card were on strips that could be moved one position by turning knobs/pushing buttons on the foot rail.

Usually, the numbered strips were the vertical columns of the card, and they could be shifted up/down one position. When a column was shifted up, the top number "wrapped" and became the bottom number. The bottom number wrapped to the top when shifting down.

bally:miss_america introduced horizontally shifting lines that used two 5x5 cards next to each other. A number could be slid from one card to the other.

The magic number is randomly chosen before the first ball is shot.

Six numbers are connected together with a chain, and they wind around such that a number can appear in any position within a 2x3 rectangle.

A ball in hole #1 cannot be pushed left, so if a ball in hole #2 is pushed left, and there is a ball in hole #1, #2 has no place to go. It rolls down the playfield to land elsewhere.

Similarly, holes #6 and #7 have the same effect when shifting balls to the right.

The screen has in-line scoring and irregularly shaped colored section scoring. In the sections, rather than needing 3,4,or 5-in-line, you can get 3,4, or 5-in-section to score. While some sections have numbers that are in a line, to win in a section, the lit numbers DO NOT need to be adjacent!

Screen Home Position	Screen Position B	Screen Position E	Screen Position G

Also notice how in position B, the green diagonal is now over three numbers that could not be a diagonal winner on the screen in the home position, but only three numbers are in the diagonal line!

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

Mystic Line Home Position	Mystic Line Winner

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.

See:

• ballyhole
• red letter game
• ok game
• futurity game
• sunny circles

Lighted panels on the backglass would tell you what the next coin played would do: advance odds, award features, etc.

You didn't know how much the scores/features might advance, but you were guaranteed at least one step.

Inserting a quarter would cycle the machine once, and add four credits to the replay register.

Two or more balls in the orange will give you a free game with guaranteed minimum odds and features lit (you could still deposit more coins/credits to try and further improve the scores/features).

One of the letters in the name of the game on the backglass would be lit in red, and the corresponding letter on a center S/I cards strip would define the guaranteed minimums.

The OK game was also called a red letter game on later model bingos and they added another level to the game play.

Do you take the two in the orange and hope for a better game next time, or do you forget the orange, move the screen to a different position and go for a high payout this game?

There were actually a few one-ball games made with five balls. The first four balls would be shot into a channel on the left top of the playfield by "skill", thus qualifying the fifth ball to be used to roll around the playfield and drop into a hole to determine win/lose.

The skill consisted of pulling the ball shooter all the way back and letting it go. Of course, the whole point was to try and convince the law that the game was not a gambling device, but required actual player talent to determine the outcome.

I doubt the court was impressed.

Usually, at least three numbers next to each other on either a horizontal, vertical, or the main 5 number diagonals are required to win.

There were, however, a few variations that occured over the years. The dimensions of the card, 2-in-line winners, and winning on the other diagonal combinations were all features that were used.

Another common feature was corners scoring.

You needed to make two balls in the five ball orange section to win.

The blue button was for scores only, the green button for features only, the red button for both scores and features, and the white button for odd game-specific features.

Why bother? Well, if you are playing in red button mode, the scores may increment one step, and a magic square may advance one step. If you are playing blue button, however, the scores may increase three steps, but you have no chance for any features to improve.

Oddly enough, this feature appeared on the second game Bally made (Spot Lite), and then didn't surface again for another 9 years.

The setup of the next game was determined by what letter in the game name on the backglass was lit in red.

On early games, the rollovers spotted numbers.

On most games, they moved the extended/extra time/play feature to after-4th for the yellow, and after-5th for the red.

Usually the boost only occurs with certain patterns on the card, like a colored vertical line, or particular section on a section scoring game.

See magic screen for a picture.

Usually the knob was disabled before the 3rd, 4th, or 5th balls was shot.

On a couple of late six card games, the knob was removed and buttons on the foot rail could be pressed to pick one of the six cards to have it's center number spotted.

Most games enable one card per coin/credit guaranteed, but a few enable the additional cards on mystery intervals.

Individual numbers light on all enabled cards at the same time, and wins on each card were scored separately, although only the highest winner on each card counted (i.e. if you had two 3-in-line winners on the same card, you got paid for only one. If you had a 3-in-line and a 4-in-line on the same card, you got paid the 4-in-line amount).

To encourage maximum coins to be played, the payouts generally increased for successive cards. The max payout for a game is usually only obtainable on card #6.

If you succeed, you immediately get paid an award that was independent of the normal game scores.

This game was completely independent from the normal bingo card scoring, and appeared to be intended for people who found the regular bingo play too complex.

The initial style of play was alternating even/odd holes. You need to make an even numbered hole on the first ball, odd on the second, etc. If you succeed on the third ball, you can stop and take the payout, or you can go double-or-nothing on the fourth. Succeed again, and you can stop or go for double-or-nothing on the fifth ball.

spottem usually refers to free numbers lit before the first ball is shot, and is a feature awarded on mystery intervals.

Interesting language can be heard when people make a ball in a hole that has been spotted, effectively wasting the ball!

Lighting all star numbers pays a big fixed award or one of the color 5-in-line amounts.

This was the only machine that had any connection between the main game and the special game. It's also the hardest special game to win.

A supercard was a smaller 3x3 card on the backglass in addition to the main card, and usually 3-in-line on a supercard paid 4-in-line scores.

On some games, corners scoring also applied to the super cards.

On a couple of games, the super line was separate from the main card, and was a row of six numbers. You would use a knob on the front of the game to select three adjacent numbers within the line. You then got paid if you lit two are more adjacent numbers in the set of three that you selected. The payout was usually 2-in-superline scores as 4-in-line, and all 3-in-superline scores as 5-in-line.

Certain color sections on the magic screen, usually marked with thin black lines, would score boost.

Two numbers lit in this section would pay like three, three pay like four, etc.

The multiplier effect may work on all wins, or wins only on colored lines.

Some games enable one card per coin/credit guaranteed, others enable the additional cards on mystery intervals.

Starting with Big Show, bally standardized the in-line scoring games to have red, yellow, and green lines.

Triple deck odds made the payout for 3,4, or 5-in-line depend on the colored line the win was in. For example, 3-in-line in red might pay 8, but three-in-line in green could pay 64.

This really introduced a whole new level of gambling to the game. Do you take a guaranteed 3-in-line winner in red and get paid 8, or do you rearrange the numbers and go for a 3 in line in green that pays 64?

The ability to move the numbers around via features like magic squares and magic lines added further strategy to the game play, and reduced the luck factor.

A common feature on this type of game was to have horizontal magic lines spanning the two cards such that numbers could be shifted from one card to the other.

The numbers are arranged in a circle, and a spinning disk inside the circle can be rotated to put the numbers into colored sections.

Since your couldn't actually move the numbers, just what color they were in, the game is not the easiest to win.

It is possible to light any of the 25 numbers with the knob, but to make it harder, the 25 numbers are divided into two color groups.

Making hole 1-3 will allow you to pick a number in one color group, making 4-7 the other color group. If you have both color groups enabled, then potting a ball in any hole #1-#7 will allow you to spot a number in either color group
