When certain symbols appear in a winning combination a special feature of the particular game theme is activated, which is a Bonus. The player can choose from several items shown on a screen. As the player chooses items, a number of credits is revealed and awarded. Some bonuses use a mechanical device, such as a spinning wheel. The amount won is displayed with the help of it in conjunction with the bonus.
A light on top of the slot machine is Candle. It flashes to alert the operator that change is needed, hand pay is requested or a potential problem with the machine.

To display the amount of money or credits on the machine Credit meter is used.
A a container located in a slot machine's base where excess coins are diverted from the hopper is Drop bucket or Drop box. A drop bucket can usually be found in low denomination slot machines.

Hand pay refers to a payout made by a slot attendant or cage, rather than the slot machine. A hand pay occurs when the amount of the payout exceeds the maximum amount that was preset by the slot machine's operator. The maximum amount is set at the level where the operator must begin to deduct taxes. A hand pay can also be a result of a short pay.
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 is Hopper fill.

While the meters count up to the amount that has been won the process of dramatizing a win by playing sounds happens which is called Rollup.
If a partial payout made by a slot machine is less than the amount due to the player it is called Short pay. This occurs if the coin hopper has been depleted as a result of making earlier payouts to players. In this case the remaining amount will be paid as a hand pay or an attendant will come and re-fill the machine.
A document provided by the manufacturer for all slot machines is called Theoretical Hold Worksheet. Basing on adequate levels of coin-in it indicates the theoretical percentage that the slot machine should hold. 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.

Here is the list of the most amusing myths concerning slots.
You can spot a winning slot machine.
The only way you'll spot a winning slot machine is when the bells are ringing and the money is dropping. RNG is the main element of every slot machine and one never knows what combination it will form.
Casinos place loose slots near the cashier, aisle ways, etc.
If this were true, it would be the only machines anyone would play. A casino mixes slots all over the casino floor. No one with any experience at playing slots would make a statement like this.
Count the number of symbols on the reels to determine your odds.
It is a rude mistake. RNG decides when the machine will stop and there are thousands of combination available on a 3 reel slot machine.
Casinos can tighten or loosen slot machines from the back office.
It is not as simple as that. The casino can’t just change the chip of the slot machine. It is illegal and it has to be permitted by the commission.
A slot machine that has not been paying is due to hit.
It is not so. With every game the chances of winning are the same.
Pulling the slot machine handle produces more wins than pressing the spin button and visa versa.
It is also a mistake. These things are only mechanisms for beginning the game. The machine knows whether you win or lose before the symbols begin to stop.
Playing with hot coins improves your chances.
It is false. Nothing can affect the outcome, the machine doesn’t care and doesn’t know whether your coins are cold or hot.
Casinos set slot machines to payback more on the weekends.
Wrong again. Your odds of winning are the same no matter if it's 4:00pm Monday, 8:00pm Saturday or 3:00am Wednesday. Casinos can not and do not do this.

The US
The United States state governments regulate the availability of slot machines. Many states have established gaming control boards for regulating the possession and use of slot machines. The only state that has no significant restrictions against slot machines is Nevada. New Jersey allows only hotel casinos operated in Atlantic City to have slot machines. Only licensed riverboats or permanently-anchored barges are allowed to have slot machines in some states. Only three horse tracks are allowed to have slot machines in Delaware. State lottery commission exists for their regulating.

Casinos: Native American
Native American casinos located in reservations are not permitted to have slot machines. It is permitted when the tribe first reaches a pact with the state in which it is located. According to the pact a fraction of the gross revenue from slot machines is received by the state.

Slot Machine Classes
No federal law governs slot machines. Each state has its own classification. There are restrictions on the type of slot machines that can be used in a casino or other gaming area in some states. A centralized computer system operates "Class III" (or "traditional") slot machines. Every play has equal chances of winning any payout. Nevada or Atlantic City have more Class III slots than any other state. They are also called "Vegas-style slots".
"Class II" slot machines ("video lottery terminals" or "VLTs") are connected to a centralized computer system. The determination of the outcome of each wager is fulfilled by it. The chance of winning a series of limited prizes is equal for each machine. A fee for each Class III game is paid by the casino to the state. Class II games are not so tightly regulated by the state.

Class II Game Characteristics
The player is playing against other players. They are competing for a common prize. Each game has a winner. The game is continued until someone wins. A given set has a certain number of wins and losses. Once a certain combination has occurred it cannot occur again until a new batch is initiated. The games depend on one another. The player is an active participant of the game. There is the same set of numbers for all players.

Characteristics Of Class III Games
The opponents are the player and the house. There is no connection between the previous and the next games. Any possible outcome can occur in any game.

Clubs Of Slot Players
Free memberships in "slot clubs" is offered by many American casinos. Complimentary food, drinks, hotel rooms, or merchandise are called comps and this is the way a small fraction of the amount of money that is bet is returned to the players. The requirement of such clubs is the usage of cards for the slot machines. Comps or "cash back" from these clubs can make significant differences in the maximum theoretical returns.

Slots In Australia
Queen of the Nile is very popular in Australia. Australian slot machines are called Gaming Machines. Australian-style gaming machines frequently use video displays to simulate physical reels. There are usually five of them. The use of gaming machines in Australia is regulated by the laws.
Not only casinos but also pubs and clubs in some states have Gaming machines. The first Australian state to legalize this style of gambling was New South Wales. The year of 1956 was the year of their legalization in all registered clubs in the state.
Western Australia only permits the use of particular forms of gaming machine.

Britain
In Britain slot machines are known as fruit machines, one-armed bandits and AWP. There are fruit machines in pubs, clubs, arcades, and some take-away food shops. These machines commonly have 3, but can be found with 4 or 6 reels with around 16 or 24 fruit symbols printed around them. These reels should be spun. The machine pays winnings if certain combinations of fruit appear. These machines and slot machines seen in casinos and elsewhere around the world are very similar. But some extra features can be found. The jackpots from these machines are limited. Fruit machines in the UK also almost universally have the following features. A player is given the opportunity to hold one or more reels before spinning. The chance of winning is sometimes increased. A finite number nudges following a spin can be also given to a player. The term nudge is used to denote a single-step rotation of a reel of the player's choice.
The maximum payout for an individual game is influenced by the type and the location of the machine. Private members' clubs have "club machines". They have higher jackpots and are allowed to charge more per game.
These machines also operate in a different manner to American slot machines. The probability of getting the jackpot in each game is independent of any other game.
The AWP fruit machine is played in Europe and in countries such as the Czech Republic, Russia, and Ukraine.
