La Bayou was a casino located on the Fremont Street Experience in Downtown Las Vegas , Nevada .
79-599: The casino had 3,200 square feet (300 m) of gaming space with 125 slot machines . By the time of its closing, La Bayou was one of the few casinos in Las Vegas where slot machines paid out in coins, rather than vouchers. The business opened in 1913 as the Las Vegas Coffee House . In 1920 Mayme Stocker renamed it the Northern Club , offering liquor and gambling when both were illegal, during

The "slot machine" term derives from the slots on the machine for inserting and retrieving coins. "Fruit machine" comes from the traditional fruit images on the spinning reels such as lemons and cherries. Slot machines are also known pejoratively as "one-armed bandits", alluding to
632-525: A "second screen" bonus round was Reel ’Em In, developed by WMS Industries in 1996. This type of machine had appeared in Australia from at least 1994 with the Three Bags Full game. With this type of machine, the display changes to provide a different game in which an additional payout may be awarded. Depending on the machine, the player can insert cash or, in " ticket-in, ticket-out " machines,
711-447: A "tilt". A theoretical hold worksheet is a document provided by the manufacturer for every slot machine that indicates the theoretical percentage the 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. Volatility or variance refers to

Lever A lever is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge , or fulcrum . A lever is a rigid body capable of rotating on a point on itself. On the basis of the locations of fulcrum, load and effort,
869-403: A finite number of spins. 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. A candle is a light on top of the slot machine. It flashes to alert

#1732776437084948-401: A fixed point. The lever operates by applying forces at different distances from the fulcrum, or a pivot. As the lever rotates around the fulcrum, points further from this pivot move faster than points closer to the pivot. Therefore, a force applied to a point further from the pivot must be less than the force located at a point closer in, because power is the product of force and velocity. If
1027-520: A help menu, along with information on other features. Historically, all slot machines used revolving mechanical reels to display and determine results. Although the original slot machine used five reels, simpler, and therefore more reliable, three reel machines quickly became the standard. A problem with three reel machines is that the number of combinations is only cubic – the original slot machine with three physical reels and 10 symbols on each reel had only 10 = 1,000 possible combinations. This limited
1106-408: A hexagonal reel formation, and much like multi-way games, any patterns not played are darkened out of use. Denominations can range from 1 cent ("penny slots") all the way up to $ 100.00 or more per credit. The latter are typically known as "high limit" machines, and machines configured to allow for such wagers are often located in dedicated areas (which may have a separate team of attendants to cater to
1185-421: A much simpler automatic mechanism with three spinning reels containing a total of five symbols: horseshoes , diamonds , spades, hearts and a Liberty Bell ; the bell gave the machine its name. By replacing ten cards with five symbols and using three reels instead of five drums, the complexity of reading a win was considerably reduced, allowing Fey to design an effective automatic payout mechanism. Three bells in

The machine is then activated by means of a lever or button (either physical or on a touchscreen), which activates reels that spin and stop to rearrange the symbols. If a player matches a winning combination of symbols, the player earns credits based on the paytable. Symbols vary depending on the theme of the machine. Classic symbols include objects such as fruits, bells, and stylized lucky sevens . Most slot games have
1343-418: A result of a short pay. Hopper fill slip is a document used to record the replenishment 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.

After a few years, the devices were banned in California, but Fey still could not keep up with the demand for them elsewhere. The Liberty Bell machine was so popular that it was copied by many slot machine manufacturers. The first of these, also called the "Liberty Bell",
1501-490: A series of spins are automatically played at no charge at the player's current wager. Free spins are usually triggered via a scatter of at least three designated symbols (with the number of spins dependent on the number of symbols that land). Some games allow the free spins bonus to "retrigger", which adds additional spins on top of those already awarded. There is no theoretical limit to the number of free spins obtainable. Some games may have other features that can also trigger over
1580-587: A skill-based slot machine game. Payline is a 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 paylines, while video slot machines may have as many as one hundred. Paylines could be of various shapes (horizontal, vertical, oblique, triangular, zigzag, etc.) Persistent state refers to passive features on some slot machines, some of which able to trigger bonus payouts or other special features if certain conditions are met over time by players on that machine. Roll-up
1659-442: A table that lists the number of credits the player will receive if the symbols listed on the pay table line up on the pay line of the machine. Some symbols are wild and can represent many, or all, of the other symbols to complete a winning line. Especially on older machines, the pay table is listed on the face of the machine, usually above and below the area containing the wheels. On video slot machines, they are usually contained within
SECTION 20
#17327764370841738-451: A theme, such as a specific style , location, or character. Symbols and other bonus features of the game are typically aligned with the theme. Some themes are licensed from popular media franchises , including films, television series (including game shows such as Wheel of Fortune , which has been one of the most popular lines of slot machines overall), entertainers, and musicians. Multi-line slot machines have become more popular since
1817-532: Is a gambling machine that creates a game of chance for its customers. A slot machine's standard layout features a screen displaying three or more reels that "spin" when the game is activated. Some modern slot machines still include a lever as a skeuomorphic design trait to trigger play. However, the mechanical operations of early machines have been superseded by random number generators , and most are now operated using buttons and touchscreens . Slot machines include one or more currency detectors that validate
1896-400: Is a display of the amount of money or number of credits on the machine. On mechanical slot machines, this is usually a seven-segment display , but video slot machines typically use stylized text that suits the game's theme and user interface. The 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
1975-429: 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.) The credit meter
2054-405: Is at least one in at least three consecutive reels from left to right. Multi-way games may be configured to allow players to bet by-reel: for example, on a game with a 3x5 pattern (often referred to as a 243-way game), playing one reel allows all three symbols in the first reel to potentially pay, but only the center row pays on the remaining reels (often designated by darkening the unused portions of
2133-451: Is evident from the recesses in the large blocks and the handling bosses which could not be used for any purpose other than for levers. The earliest remaining writings regarding levers date from the 3rd century BC and were provided, by common belief, by the Greek mathematician Archimedes , who famously stated "Give me a lever long enough and a fulcrum on which to place it, and I shall move

2449-432: 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

Pastor would later also own the nearby Sassy Sally's casino and the Girls of Glitter Gulch strip club. Pastor decided in 1999 to move ahead with a renovation plan to transform the Coin Castle and Sassy Sally's into La Bayou and Mermaids, respectively, for a total of $ 6 million. In 2006, Pastor's son, Steve Burnstine, purchased

In Mesopotamia (modern Iraq) c. 3000 BC , the shadouf , a crane-like device that uses a lever mechanism, was invented. In ancient Egypt , workmen used the lever to move and uplift obelisks weighing more than 100 tons. This
2844-439: The 1990s. These machines have more than one payline, meaning that visible symbols that are not aligned on the main horizontal may be considered as winning combinations. Traditional three-reel slot machines commonly have one, three, or five paylines while video slot machines may have 9, 15, 25, or as many as 1024 different paylines. Most accept variable numbers of credits to play, with 1 to 15 credits per line being typical. The higher
2923-402: The amount bet, the higher the payout will be if the player wins. One of the main differences between video slot machines and reel machines is in the way payouts are calculated. With reel machines, the only way to win the maximum jackpot is to play the maximum number of coins (usually three, sometimes four or even five coins per spin). With video machines, the fixed payout values are multiplied by
3002-415: The city had one or more of them. Players would insert a nickel and pull a lever, which would spin the drums and the cards that they held, the player hoping for a good poker hand. There was no direct payout mechanism, so a pair of kings might get the player a free beer, whereas a royal flush could pay out cigars or drinks; the prizes were wholly dependent upon what the establishment would offer. To improve

Monte Carlo Club would close in 1956, but remain in business as a bar until the 1960s. The original building was razed after 1965. A new building was erected, where a Denny's diner opened c. 1967–1968, followed by Sam's Roast Beef c. 1968–1969. By 1970, the site was operating as

3318-862: The display and logic boards for all slot-machine functions. The prototype was mounted in a full-size, show-ready slot-machine cabinet. The first production units went on trial at the Las Vegas Hilton Hotel . After some modifications to defeat cheating attempts, the video slot machine was approved by the Nevada State Gaming Commission and eventually found popularity on the Las Vegas Strip and in downtown casinos. Fortune Coin Co. and its video slot-machine technology were purchased by IGT (International Gaming Technology) in 1978. The first American video slot machine to offer
3397-597: The first slot machine with a bottomless hopper and automatic payout of up to 500 coins without the help of an attendant. The popularity of this machine led to the increasing predominance of electronic games , with the side lever soon becoming vestigial. The first video slot machine was developed in 1976 in Kearny Mesa, California by the Las Vegas–based Fortune Coin Co. This machine used a modified 19-inch (48 cm) Sony Trinitron color receiver for

3555-400: The forces that are perpendicular to the radial segments PA and PB . The principle of virtual work states that at equilibrium the generalized force is zero, that is F θ = a F A − b F B = 0. {\displaystyle F_{\theta }=aF_{A}-bF_{B}=0.\,\!} Thus, the ratio of the output force F B to
3634-420: The form of payment, whether coin , banknote , voucher , or token . The machine pays out according to the pattern of symbols displayed when the reels stop "spinning". Slot machines are the most popular gambling method in casinos and contribute about 70% of the average U.S. casino's income. Digital technology has resulted in variations in the original slot machine concept. As the player is essentially playing
3713-399: The game (similarly to a joker card), usually excluding scatter and jackpot symbols (or offering a lower prize on non-natural combinations that include wilds). How jokers behave are dependent on the specific game and whether the player is in a bonus or free games mode. Sometimes wild symbols may only appear on certain reels, or have a chance to "stack" across the entire reel. Each machine has
3792-426: The input force F A is obtained as M A = F B F A = a b , {\displaystyle MA={\frac {F_{B}}{F_{A}}}={\frac {a}{b}},} which is the mechanical advantage of the lever. This equation shows that if the distance a from the fulcrum to the point A where the input force is applied is greater than the distance b from fulcrum to
3871-419: The input force. On the other hand, if the distance a from the fulcrum to the input force is less than the distance b from the fulcrum to the output force, then the lever reduces the input force. The use of velocity in the static analysis of a lever is an application of the principle of virtual work . A lever is modeled as a rigid bar connected to a ground frame by a hinged joint called a fulcrum. The lever
3950-440: The large mechanical levers affixed to the sides of early mechanical machines, and to the games' ability to empty players' pockets and wallets as thieves would. Sittman and Pitt of Brooklyn , New York , developed a gambling machine in 1891 that was a precursor to the modern slot machine. It contained five drums holding a total of 50 card faces and was based on poker . The machine proved extremely popular, and soon many bars in

SECTION 50
#17327764370844108-405: The lever equals the power out, and the ratio of output to input force is given by the ratio of the distances from the fulcrum to the points of application of these forces. This is known as the law of the lever . The mechanical advantage of a lever can be determined by considering the balance of moments or torque , T , about the fulcrum. If the distance traveled is greater, then the output force
4187-526: The lever is divided into three types . It is one of the six simple machines identified by Renaissance scientists. A lever amplifies an input force to provide a greater output force, which is said to provide leverage , which is mechanical advantage gained in the system, equal to the ratio of the output force to the input force. As such, the lever is a mechanical advantage device , trading off force against movement. The word "lever" entered English around AD 1300 from Old French : levier . This sprang from
4266-413: The machine, the courts ruled that "[t]he machine appealed to the player's propensity to gamble, and that is [a] vice." In 1963, Bally developed the first fully electromechanical slot machine called Money Honey (although earlier machines such as Bally's High Hand draw-poker machine had exhibited the basics of electromechanical construction as early as 1940). Its electromechanical workings made Money Honey
4345-410: The machine. A scatter is a pay combination based on occurrences of a designated symbol landing anywhere on the reels, rather than falling in sequence on the same payline. A scatter pay usually requires a minimum of three symbols to land, and the machine may offer increased prizes or jackpots depending on the number that land. Scatters are frequently used to trigger bonus games, such as free spins (with
4424-441: The manufacturer's ability to offer large jackpots since even the rarest event had a likelihood of 0.1%. The maximum theoretical payout, assuming 100% return to player would be 1000 times the bet, but that would leave no room for other pays, making the machine very high risk, and also quite boring. Although the number of symbols eventually increased to about 22, allowing 10,648 combinations, this still limited jackpot sizes as well as
4503-455: The measure of risk associated with playing a slot machine. A low-volatility slot machine has regular but smaller wins, while a high-variance slot machine has fewer but bigger wins. Weight count is an American term referring to the total value of coins or tokens removed from a slot machine's drop bucket or drop box for counting by the casino's hard count team through the use of a weigh scale. Wild symbols substitute for most other symbols in
4582-412: The minimum out over the course of several pulls. Tilt is a term derived from electromechanical slot machines' " tilt switches ", which would make or break a circuit when they were tilted or otherwise tampered with that triggered 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
4661-477: The multiple reel. In 1984, Inge Telnaes received a patent for a device titled, "Electronic Gaming Device Utilizing a Random Number Generator for Selecting the Reel Stop Positions" (US Patent 4448419), which states: "It is important to make a machine that is perceived to present greater chances of payoff than it actually has within the legal limitations that games of chance must operate." The patent
4740-406: The needs of those who play there). The machine automatically calculates the number of credits the player receives in exchange for the cash inserted. Newer machines often allow players to choose from a selection of denominations on a splash screen or menu. A bonus is a special feature of the particular game theme, which is activated when certain symbols appear in a winning combination. Bonuses and

The malleus , incus and stapes are small bones in the middle ear , connected as compound levers, that transfer sound waves from the eardrum to the oval window of the cochlea . The lever is a movable bar that pivots on a fulcrum attached to
SECTION 60
#17327764370844898-497: The number of bonus features 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/or other multipliers or increased frequencies of symbols, or a "hold and re-spin" mechanic in which specific symbols (usually marked with values of credits or other prizes) are collected and locked in place over
4977-457: The number of coins per line that is being bet. In other words: on a reel machine, the odds are more favorable if the gambler plays with the maximum number of coins available. However, depending on the structure of the game and its bonus features, some video slots may still include features that improve chances at payouts by making increased wagers. "Multi-way" games eschew fixed paylines in favor of allowing symbols to pay anywhere, as long as there
5056-421: The number of possible outcomes. In the 1980s, however, slot machine manufacturers incorporated electronics into their products and programmed them to weight particular symbols. Thus the odds of losing symbols appearing on the payline became disproportionate to their actual frequency on the physical reel. A symbol would only appear once on the reel displayed to the player, but could, in fact, occupy several stops on
5135-455: The number of spins multiplying based on the number of scatter symbols that land). The scatter symbol usually cannot be matched using wilds, and some games may require the scatter symbols to appear on consecutive reels in order to pay. On some multiway games, scatter symbols still pay in unused areas. 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 even
5214-553: The odds for the house, two cards were typically removed from the deck , the ten of spades and the jack of hearts , doubling the odds against winning a royal flush. The drums could also be rearranged to further reduce a player's chance of winning. Because of the vast number of possible wins in the original poker-based game, it proved practically impossible to make a machine capable of awarding an automatic payout for all possible winning combinations. At some time between 1887 and 1895, Charles Fey of San Francisco , California devised
5293-412: The operator that change is needed, hand pay is requested, a potential problem with the machine or the progressive jackpot has been won. It can be lit by the player by pressing the "service" or "help" button. Carousel refers to a grouping of slot machines, usually in a circle or oval formation. A coin hopper is a container where the coins that are immediately available for payouts are held. The hopper
5372-530: The origin of the bar symbol, was also present. This set of symbols proved highly popular and was used by other companies that began to make their own slot machines: Caille , Watling, Jennings and Pace. A commonly used technique to avoid gambling laws in several states was to award food prizes. For this reason, several gumball and other vending machines were regarded with mistrust by the courts. The two Iowa cases of State v. Ellis and State v. Striggles are both used in criminal law classes to illustrate

Levers are classified by the relative positions of the fulcrum, effort and resistance (or load). It is common to call the input force "effort" and the output force "load" or "resistance". This allows the identification of three classes of levers by the relative locations of the fulcrum,
5609-415: The reels). Other multi-way games use a 4x5 or 5x5 pattern, where there are up to five symbols in each reel, allowing for up to 1,024 and 3,125 ways to win respectively. The Australian manufacturer Aristocrat brands games featuring this system as "Reel Power", "Xtra Reel Power" and "Super Reel Power" respectively. A variation involves patterns where symbols are adjacent to one another. Most of these games have
5688-424: The resistance and the effort: These cases are described by the mnemonic fre 123 where the f fulcrum is between r and e for the 1st class lever, the r resistance is between f and e for the 2nd class lever, and the e effort is between f and r for the 3rd class lever. A compound lever comprises several levers acting in series: the resistance from one lever in a system of levers acts as effort for
5767-550: The stem of the verb lever , meaning "to raise". The verb, in turn, goes back to Latin : levare , itself from the adjective levis , meaning "light" (as in "not heavy"). The word's primary origin is the Proto-Indo-European stem legwh- , meaning "light", "easy" or "nimble", among other things. The PIE stem also gave rise to the English word "light". The earliest evidence of the lever mechanism dates back to
