Slot Machine Terminology

Bonus is a special feature of the particular game theme, which is activated when certain symbols appear in a winning combination. Bonuses vary depending upon the game. Some bonus rounds are a special session of free spins the number of which is often based on the winning combination that triggers the bonus, often with a different or modified set of winning combinations as the main game, and often with winning credit values increased by a specific multiplier, which is prominently displayed as part of the bonus graphics and/or animation. In other bonus rounds, the player is presented with several items on a screen from which to choose. As the player chooses items, a number of credits is revealed and awarded. Some bonuses use a mechanical device, such as a spinning wheel, that works in conjunction with the bonus to display the amount won.

Candle is a light on top of the slot machine. It flashes to alert the operator that change is needed, hand pay is requested or a potential problem with the machine.

Carousel refers to a grouping of slot machines, usually in a circle or oval formation.

Coin hopper is a container where the coins that are immediately available for payouts are held. The hopper is a mechanical device that rotates coins into the coin tray when a player collects credits/coins by pressing a Cash Out button. When a certain preset coin capacity is reached, a coin diverter automatically redirects, or drops, excess coins into a drop bucket or drop box. Unused coin hoppers can still be found even on games that exclusively employ Ticket-In Ticket-Out technology, as a vestige.

Credit meter is a visual LED display of the amount of money or credits on the machine. On video reel machines this is either a simulated LED display, or represented in a different font altogether, based on the design of the game graphics.

Drop bucket or drop box is a container located in a slot machine's base where excess coins are diverted from the hopper. Typically, a drop bucket is used for low denomination slot machines and a drop box is used for high denomination slot machines. A drop box contains a hinged lid with one or more locks whereas a drop bucket does not contain a lid. The contents of drop buckets and drop boxes are collected and counted by the casino on a scheduled basis.

EGM is used as shorthand for Electronic Gaming Machine.

Hand pay refers to a payout made by an attendant or at an exchange point cage, rather than by the slot machine itself. A hand pay occurs when the amount of the payout exceeds the maximum amount that was preset by the slot machine's operator. Usually, the maximum amount is set at the level where the operator must begin to deduct taxes. A hand pay could also be necessary as a result of a short pay.

Hopper fill slip is a document used to record the replenishments of the coin in the coin hopper after it becomes depleted as a result of making payouts to players. The slip indicates the amount of coin placed into the hoppers, as well as the signatures of the employees involved in the transaction, the slot machine number and the location and the date.

MEAL book Machine entry authorization log is a log of the employee's entries into the machine

Low Level or Slant Top slot machines include a stool so the player has sit-down access. Stand Up or Upright slot machines are played while standing.

Optimal play is a payback percentage based on a gambler using the optimal strategy in a skill-based slot machine game.

Pay line is a straight or zigzagged line that crosses through one symbol on each reel, along which a winning combination is evaluated. Classic spinning reel machines usually have up to nine pay lines, while video slot machines may have as many as one hundred.

Rollup is the process of dramatizing a win by playing sounds while the meters count up to the amount that has been won.

Short pay refers to a partial payout made by a slot machine, which is less than the amount due to the player. This occurs if the coin hopper has been depleted as a result of making earlier payouts to players. The remaining amount due to the player is either paid as a hand pay or an attendant will come and refill the machine.

Taste is a reference to the small amount often paid out to keep a player seated and continuously betting. Only rarely will machines fail to pay out even the minimum placed bet over the course of several pulls.

Tilt Electromechanical slot machines usually include an electromechanical tilt switch, which makes or breaks a circuit if the machine is tilted or otherwise tampered with, and so triggers an alarm. While modern machines no longer have tilt switches, any kind of technical fault door switch in the wrong state, reel motor failure, out of paper, etc. is still called a tilt.

Theoretical Hold Worksheet A document provided by the manufacturer for all slot machines, which indicates the theoretical percentage that the slot machine should hold based on the amount paid in. The worksheet also indicates the reel strip settings, number of coins that may be played, the payout schedule, the number of reels and other information descriptive of the particular type of slot machine.

Weight count is an American term, referring to the dollar amount of coins or tokens removed from a slot machine's drop bucket or drop box and counted by the casino's hard count team through the use of a weigh scale.

Blind

The blinds are forced bets posted by players to the left of the dealer button in flop-style poker games. The number of blinds is usually two, but it can range from none to three.

The small blind is placed by the player to the left of the dealer button and the big blind is then posted by the next player to the left. The one exception is when there are only two players a heads-up game, when the player on the button is the small blind, and the other player is the big blind. Both the player and the bet may be referred to as big or small blind.

After the cards are dealt, the player to the left of the big blind is the first to act during the first betting round. If all players call the big blind, the big blind is then given an extra opportunity to raise. This is known as a live blind. If the live blind checks, the betting round then ends.

Generally, the big blind is equal to the minimum bet. The small blind is normally half the big blind. In cases where posting exactly half the big blind is impractical due to the big blind being some odd-valued denomination, the small blind is rounded down to the nearest practical value. For example, if the big blind in a live table game is $3 then the small blind will usually be $1 or $2 since most casinos do not distribute large quantities of $0.50 poker chips.

The blinds exist because Omaha and Texas hold 'em are frequently played without antes, allowing a player to fold his hand without placing a bet. The blind bets introduce a regular cost to take part in the game, thus inducing a player to enter pots in an attempt to compensate for that expense.

It is possible to play without blinds. The minimum bet is then the lowest denomination chip in play, and tossing only 1 chip is considered a call. Anything higher than that is considered a raise. Poker without blinds is usually played with everyone posting an ante to receive cards, but it is technically possible to have absolutely no ante or blinds at all.

Pachinko

Pachinko is a Japanese gaming device. A pachinko machine resembles a vertical pinball machine, but has no flippers and uses a large number of small balls. The player fires balls into the machine, which then cascade down through a dense forest of pins. If the balls go into certain locations, sequences of events are triggered that result in more balls being released; these balls can then be exchanged for prizes. Pachinko machines were originally strictly mechanical, but modern ones have incorporated extensive electronics, becoming similar to video slot machines.

The machines are widespread in establishments called parlors, which feature a number of slot machines; hence, they operate and look similar to casinos. Modern pachinko machines are highly customizable, keeping enthusiasts continuously entertained. Because gambling for cash is illegal in Japan, balls won cannot be exchanged directly for cash in the parlor; instead the balls are exchanged for tokens, which are then taken outside and exchanged for cash at a place nominally separate from the parlor and possibly run by organized crime.

As an indicator of the popularity of pachinko in Japan, Japanese government estimates of the annual turnover of the pachinko industry are in the region of 29 trillion yen. To put this in perspective, this is about twice the annual turnover of Japan's automobile industry, and approximately equivalent to the estimated annual turnover of the global narcotics trade.

Pachinko parlors are known for tweaking their machines to maximize their profits without intimidating customers, which means that most machines have different payout settings than what their manufacturers claim. The Japanese police can tolerate such manipulation as long as it happens outside of business hours; generally, those that cause a loss to the player are found in greater numbers.

Resetting of machines every day before opening hours is a feature of all parlors, because of the strict enforcement of closing times implying some players having to give up their machines when they hit a string of jackpots. Those whose machines are in payout mode at this time are allowed to collect their balls for the duration of the payout. Some parlors allow members to hold a particular machine across operating sessions. Timing is another factor in determining how parlors set their machines: holidays, when many people play pachinko, are favorable because many play it for leisure and the parlors are keen to attract them to come back for more. Weekends are unfavorable because the majority of players have only this time to play.

The layout of the different setting machines is a psychological method of attracting players; machines near the entrance are usually set at a high payout rate. When people walk by the parlor and see players at those machines with a large number of balls, they are more inclined to go inside and play the other machines even though they are at lower settings. For this purpose, many parlors employ "sakuras" to sit at these machines and emulate players winning a large number of balls; they are required to return these balls to the parlor free of charge minus their wages.
