Shuffling

Shuffling is a procedure used to randomize a deck of playing cards to provide an element of chance in card games. Shuffling is often followed by a cut, to help ensure that the shuffler has not manipulated the outcome. A common shuffling technique is called the riffle or dovetail shuffle, in which half of the deck is held in each hand with the thumbs inward, then cards are released by the thumbs so that they fall to the table interleaved. Many also lift the cards up after a riffle, forming what is called a bridge which puts the cards back into place. This can also be done by placing the halves flat on the table with their rear corners touching, then lifting the back edges with the thumbs while pushing the halves together. While this method is more difficult, it is often used in casinos because it minimizes the risk of exposing cards during the shuffle. There are two types of perfect riffle shuffles: if the top card moves to be 2nd from the top then it is an in shuffle, otherwise it is known as an out shuffle which preserves both the top and bottom cards.

Riffle shuffling does, however, carry a risk of damaging cards from excessive bending. Casinos often replace their playing cards to prevent cheating from players that detect deformations in the cards. However, collectible card game cards are considerably less replaceable than playing cards, and CCG cards can be damaged from riffle shuffling, even when protected with card sleeves.

Because standard shuffling techniques are seen as weak, and in order to avoid inside jobs where employees collaborate with gamblers by performing inadequate shuffles, many casinos employ automatic shuffling machines. They also save time that would otherwise be spent shuffling, allowing several more hands per hour to be played and increasing the profitability of the table. These machines are also used to lessen repetitive motion stress injuries to a dealer. Note that the shuffling machines have to be carefully designed, as they can generate biased shuffles otherwise: the most recent shuffling machines are computer-controlled, though they have not yet fully been integrated into gaming.

Slot Machine History

The first slot machine was invented by Charles Fey of San Francisco, California, U.S., who devised a much simpler automatic mechanism. Most assert that Fey invented the machine in 1887; however some believe that he may have conceived the machine in 1895. Due to the vast number of possible wins with the original poker card based game, it proved practically impossible to come up with a way to make a machine capable of making an automatic payout for all possible winning combinations. Charles Fey devised a machine with three spinning reels containing a total of five symbols – horseshoes, diamonds, spades, hearts, and a Liberty Bell, which also 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 devise an effective automatic payout mechanism. Three bells in a row produced the biggest payoff, ten nickels. Liberty Bell was a huge success and spawned a thriving mechanical gaming device industry. Even when the use of these gambling devices was banned in his home state after a few years, Fey still couldn't keep up with demand for the game elsewhere. Liberty Bell machine was so popular that it was copied by many slot machine manufacturers. Thus in 1907, manufacturer Herbert Mills from Chicago produced a slot machine called the Operator Bell. By 1908 lots of bell machines were installed in most cigar stores, saloons, bowling alleys, brothels and barber stores. The original Liberty Bell slot machine can still be seen at the Liberty Belle Saloon & Restaurant in Reno, Nevada.

Sittman and Pitt of Brooklyn, New York, U.S. developed a gambling machine in 1891 which was a precursor to the modern slot machine. It contained five drums holding a total of 50 card faces and was based on poker. This machine proved extremely popular and soon many bars in the city had one or more of the machines. Players would insert a nickel and pull a lever, which would spin the drums and the cards 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 wholly dependent on what was on offer at the local establishment. To make the odds better for the house, two cards were typically removed from the deck: the ten of spades and the jack of hearts, which doubles the odds against winning a royal flush. The drums could also be rearranged to further reduce a player's chance of winning.

Another early machine gave out winnings in the form of fruit flavored chewing gums with pictures of the flavours as symbols on the reels. The popular cherry and melon symbols derive from this machine. The BAR symbol now common in slot machines was derived from an early logo of the Bell-Fruit Gum Company. The payment of food prizes was a commonly used technique to avoid laws against gambling in a number of states, and for this reason a number of gumball and other vending machines were regarded with mistrust by the courts. The two Iowa cases of State v. Ellis6 and State v. Striggles7 are both used in classes on criminal law to illustrate the concept of reliance upon authority as it relates to the axiomatic ignorantia juris non excusat Ignorance of the law is no excuse.8 In these cases, a mint vending machine was declared to be a gambling device because by internally manufactured chance the machine would occasionally give the next user a number of tokens exchangeable for more candy. Despite the fact that the result of the next use would be displayed on the machine, both courts ruled that The inducement for each play was the chance that by that play the machine would be set to indicate that it would pay checks on the following play. The thing that attracted the player was the chance that ultimately he would receive something for nothing. The machine appealed to the player's propensity to gamble, and that is a vice.9

In 1963, Bally developed the first fully electromechanical slot machine called Money Honey, although earlier machines such as the High Hand draw poker machine by Bally had exhibited the basics of electromechanical construction as early as 1940. The electromechanical approach of the 1960s allowed Money Honey to be 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, and the side lever soon became vestigial.

The first true, video slot machine was developed in 1976 in an industrial suite in Kearney Mesa, CA by N. Cerracchio, R. Greene, W. Beckman, J. Reukes, and L. Black under the direction of Fortune Coin Co., Las Vegas, NV. This slot machine used a modified 19 Sony Trinitron color receiver for 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 in the Las Vegas Hilton Hotel. After some cheat-proofing modifications, the video slot machine was approved by the Nevada State Gaming Commission and eventually found popularity in Las Vegas Strip and downtown casinos. Fortune Coin Co. and their video slot machine technology were purchased by IGT International Gaming Technology in 1978.

The first American video slot machine to offer a second screen bonus round was Reel 'Em In developed by WMS Industries Inc. in 1996.11 This type of machine had appeared in Australia from at least 1994 with the Three Bags Full game.12 In this type of machine, the display changes to provide a different game where an additional payout may be won or accumulated.

Poker Ante

An ante is a forced bet in which all players put an equal amount of money or chips into the pot before the deal begins. Often this is either a single unit a one-value or the smallest value in play or some other small amount; a proportion such as a half or a quarter of the minimum bet is also common. An ante paid by every player ensures that a player who folds every round will lose money though slowly, thus providing all players with an incentive, however small; to play the hand rather than toss it in when the opening bet reaches them.

Antes are the most common forced bet in draw poker and stud poker but are uncommon in games featuring blind bets see next section. However, some tournament formats of games featuring blinds impose an ante to discourage extremely tight play. Antes encourage players to play more loosely by lowering the cost of staying in the hand calling relative to the current pot size, offering better pot odds. With antes, more players stay in the hand, which increases pot size and makes for more interesting play. This is considered important to ensure good ratings for televised tournament final. Most televised high stakes cash games also use both blinds and antes. Televised cash games usually have one of the players pay for everyone, normally the dealer, to accelerate play. If there are six players for example, the dealer would toss six times the ante into the pot, paying for each person.

In live cash games where the acting dealer changes each turn, it is not uncommon for the players to agree that the dealer or some other position relative to the button provides the ante for each player. This simplifies betting, but causes minor inequities if other players come and go or miss their turn to deal. During such times, the player can be given a special button indicating the need to pay an ante to the pot known as "posting"; see below upon their return. Some card rooms eliminate these inequities by always dealing all players into every hand whether they are present or not. In such cases casino staff or neighboring players under staff supervision will be expected to post antes and fold hands on behalf of absent players as necessary.
