Shuffling

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.

Deuce-to-Seven

Deuce-to-seven low is often called Kansas City lowball the no-limit single-draw variation or just low poker. It is almost the direct opposite of standard poker: high hand loses. It is not as commonly used as the ace-to-five low method.

As in all lowball games, pairs and trips are bad: that is, any hand with no pair defeats any hand with a pair; one pair hands defeat two pair or trips, etc. No-pair hands are compared starting with the highest ranking card, just as in high poker, except that the high hand loses. In deuce-to-seven low, straights and flushes count for high and are therefore bad. Aces are always high and therefore bad.

For example, the hand 8-5-4-3-2 defeats 9-7-6-4-3, because eight-high is lower than nine-high. The hand 7-6-5-4-2 defeats both, because seven-high is lower still. The hand 7-6-5-4-3 would lose, because it is a straight. Aces are high, so Q-8-5-4-3 defeats A-8-5-4-3. In the rare event that hands with pairs tie, kickers are used just as in high poker but reversed: 3-3-6-4-2 defeats 3-3-6-5-2.

Since the ace always plays high, A-5-4-3-2 is not considered a straight; is simply ace-high no pair it would therefore lose to any king-high, but would defeat A-6-4-3-2.

The best possible hand is 7-5-4-3-2 hence the name deuce-to-seven low, followed by 7-6-4-3-2, 7-6-5-3-2, 7-6-5-4-2, 8-5-4-3-2, 8-6-4-3-2, etc. Hands are sometimes referred to by their absolute rank, e.g. 7-5-4-3-2 #1, said 'number one'.

When speaking, low hands are referred to by their highest ranking card or cards. Any nine-high hand can be called a nine, and is defeated by any eight. Two cards are frequently used: the hand 8-6-5-4-2 can be called an eight-six and will defeat an eight-seven such as 8-7-5-4-2.

Another common notation is calling a particular low hand smooth or rough. A smooth low hand is one where the remaining cards after the highest card are themselves very low; a rough low hand is one where the remaining cards are high. For instance, 8-7-6-4-2 would be referred to as a rough eight, but 8-5-4-3-2 would be referred to as a smooth eight.

Wild cards are rarely used in deuce-to-seven games, but if used they play as whatever rank would make the lowest hand. Thus, in 7-6-Joker-3-2, the joker plays as a 4, while in Joker-5-4-3-2 it would play as a 7 a six would make a straight, and an ace would make ace-five high.

In most jurisdictions worldwide, gambling is limited to persons over the age of license in most countries where casinos are permitted.

Customers gamble by playing games of chance, in some cases with an element of skill, such as craps, roulette, baccarat, blackjack, and video poker. Most games played have mathematically determined odds that ensure the house has at all times an advantage over the players. This can be expressed more precisely by the notion of expected value, which is uniformly negative from the player's perspective. This advantage is called the house edge. In games such as poker where players play against each other, the house takes a commission called the rake. Casinos sometimes give out complimentary items to gamblers.

Payout is the percentage won by players.

Casinos in the USA say that a player staking money won from the casino is playing with house money.

Video Lottery Machines slot machines have become one of the most popular form of gambling in casinos. Recently, investigative reports have been calling into question whether the modern day slot machine is addictive. There are almost 900 casinos now in the United States, with that number steadily growing as more states seek to legalize casinos. 38 states now have some form of casino gambling. Relatively small places such as Las Vegas are best known for gambling; larger cities such as Chicago are not defined by their casinos in spite of the large turnover.

Las Vegas has the largest concentration of casinos in the United States. Based on revenue, Atlantic City, New Jersey ranks second and the Chicago region third.
