Slot machines are a popular type of casino game.
Games available in most casinos are commonly called casino games. In a casino game, the players gamble cash or casino chips on various possible random outcomes or combinations of outcomes. Casino games are also available in online casinos, where permitted by law. Casino games can also be played outside casinos for entertainment purposes like in parties or in school competitions, some on machines that simulate gambling.

There are three general categories of casino games: gaming machines, table games, and random number games. Gaming machines, such as slot machines and pachinko, are usually played by one player at a time and do not require the involvement of casino employees to play. Tables games, such as blackjack or craps, involve one or more players who are competing against the house (the casino itself) rather than each other. Table games are usually conducted by casino employees known as croupiers or dealers. Random number games are based upon the selection of random numbers, either from a computerized random number generator or from other gaming equipment. Random number games may be played at a table or through the purchase of paper tickets or cards, such as keno or bingo.
Some casino games combine multiple of the above aspects; for example, roulette is a table game conducted by a dealer, which involves random numbers. Casinos may also offer other type of gaming, such as hosting poker games or tournaments, where players compete against each other.
Common casino games[edit]
Notable games that are commonly found at casinos include:

House advantage[edit]
Casino games typically provide a predictable long-term advantage to the casino, or 'house', while offering the players the possibility of a short-term gain that in some cases can be large. Some casino games have a skill element, where the players' decisions have an impact on the results. Players possessing sufficient skills to eliminate the inherent long-term disadvantage (the house edge or vigorish) in a casino game are referred to as advantage players.
The players' disadvantage is a result of the casino not paying winning wagers according to the game's 'true odds', which are the payouts that would be expected considering the odds of a wager either winning or losing. For example, if a game is played by wagering on the number that would result from the roll of one die, true odds would be 5 times the amount wagered since there is a 1 in 6 chance of any single number appearing, assuming that the player gets the original amount wagered back. However, the casino may only pay 4 times the amount wagered for a winning wager.
The house edge or vigorish is defined as the casino profit expressed as the percentage of the player's original bet. (In games such as blackjack or Spanish 21, the final bet may be several times the original bet, if the player double and splits.)
A European roulette ('single zero') wheel
In American roulette, there are two 'zeroes' (0, 00) and 36 non-zero numbers (18 red and 18 black). This leads to a higher house edge compared to European roulette. The chances of a player, who bets 1 unit on red, winning is 18/38 and his chances of losing 1 unit is 20/38. The player's expected value is EV = (18/38 × 1) + (20/38 × (−1)) = 18/38 − 20/38 = −2/38 = −5.26%. Therefore, the house edge is 5.26%. After 10 spins, betting 1 unit per spin, the average house profit will be 10 × 1 × 5.26% = 0.53 units. European roulette wheels have only one 'zero' and therefore the house advantage (ignoring the en prison rule) is equal to 1/37 = 2.7%.
The house edge of casino games varies greatly with the game, with some games having an edge as low as 0.3%. Keno can have house edges up to 25%, slot machines having up to 15%.
The calculation of the roulette house edge was a trivial exercise; for other games, this is not usually the case. Combinatorial analysis and/or computer simulation is necessary to complete the task.
In games which have a skill element, such as blackjack or Spanish 21, the house edge is defined as the house advantage from optimal play (without the use of advanced techniques such as card counting), on the first hand of the shoe (the container that holds the cards). The set of the optimal plays for all possible hands is known as 'basic strategy' and is highly dependent on the specific rules and even the number of decks used. Good blackjack and Spanish 21 games have house edges below 0.5%.
Traditionally, the majority of casinos have refused to reveal the house edge information for their slots games and due to the unknown number of symbols and weightings of the reels, in most cases it is much more difficult to calculate the house edge than that in other casino games. However, due to some online properties revealing this information and some independent research conducted by Michael Shackleford in the offline sector, this pattern is slowly changing.[1]
In games where players are not competing against the house, such as poker, the casino usually earns money via a commission, known as a 'rake'.
Standard deviation[edit]
The luck factor in a casino game is quantified using standard deviations (SD).[2] The standard deviation of a simple game like roulette can be calculated using the binomial distribution. In the binomial distribution, SD = √npq, where n = number of rounds played, p = probability of winning, and q = probability of losing. The binomial distribution assumes a result of 1 unit for a win, and 0 units for a loss, rather than −1 units for a loss, which doubles the range of possible outcomes. Furthermore, if we flat bet at 10 units per round instead of 1 unit, the range of possible outcomes increases 10 fold.[3]
- SD (roulette, even-money bet) = 2b√npq, where b = flat bet per round, n = number of rounds, p = 18/38, and q = 20/38.
For example, after 10 rounds at 1 unit per round, the standard deviation will be 2 × 1 × √10 × 18/38 × 20/38 = 3.16 units. High 5 casino codes. After 10 rounds, the expected loss will be 10 × 1 × 5.26% = 0.53. As you can see, standard deviation is many times the magnitude of the expected loss.[4]
The standard deviation for pai gow poker is the lowest out of all common casino games. Many casino games, particularly slot machines, have extremely high standard deviations. The bigger size of the potential payouts, the more the standard deviation may increase.
As the number of rounds increases, eventually, the expected loss will exceed the standard deviation, many times over. From the formula, we can see the standard deviation is proportional to the square root of the number of rounds played, while the expected loss is proportional to the number of rounds played. As the number of rounds increases, the expected loss increases at a much faster rate. This is why it is impossible for a gambler to win in the long term. It is the high ratio of short-term standard deviation to expected loss that fools gamblers into thinking that they can win.
It is important for a casino to know both the house edge and variance for all of their games. The house edge tells them what kind of profit they will make as percentage of turnover, and the variance tells them how much they need in the way of cash reserves. The mathematicians and computer programmers that do this kind of work are called gaming mathematicians and gaming analysts. Casinos do not have in-house expertise in this field, so outsource their requirements to experts in the gaming analysis field.

As far back as 1797, Casino was described in books on card games. Though the game has quite a few details, it's easy to learn and fun to play, with lots of suspense and surprise. Here's how to play:
Number of players: Two

Object: To score points by taking cards.
The cards: Standard 52-card deck
Playing: Deal four cards to each player and four cards faceup on the table. Dealer keeps the rest of the pack handy. Nondealer plays a card first; players then alternate until the round is over. You can combine the card you play with cards on the table in many possible ways.
Matching: If your card matches by rank a card on the table, you can take the pair immediately. Place the two cards facedown in front of you on the table. Face cards can be taken only with other face cards and only in pairs -- if two queens are on the table and you hold another queen, you can take only one of the queens. However, if three matching face cards are on the table and you hold the fourth, you can take all four.
Combining: If your card equals the combined sum of two or more cards on the table, you can take those cards immediately.
Building: If at least one free card on the table, plus the card you play, totals the number of a card in your hand, announce this build number and pile up the build to take later. For example, if there is a 6 on the table and you have a 3 and a 9 in your hand, you could play the 3 onto the 6 and say 'Building 9s.' On your next turn, if your opponent hasn't taken it, you can take the build with your 9.
Your opponent can change the value of a build by playing another card. In this case, opponent can play an ace on the build and say 'Building 10s.' This tells you he or she has a 10 with which to take the build.
But if your 9 build is still there and if you have two 9s in your hand, on your next turn you can put one of them on top of the build and say, 'Still building 9s,' intending to take the build with your remaining 9. This creates a double build. Players can't change the value of a double build.
Once you have made a build, on your next turn you must take the build, add to the build, or make a new build. Leaving a build untaken runs the risk that opponent will take it, but you may leave a build behind as long as you can add cards to it or make another play. Nothing prevents you from taking opponent's build; you can do so if you have the right card. On the other hand, nothing prevents your opponent from taking your build!

Trailing: You may also play a card by trailing it -- placing it on the table without building it onto another card. You can't do this if you have made a build that's still on the table. You must trail a card if you can't do anything else on your turn. For strategic reasons, a player might want to trail a card onto the table even though it matches the rank of one already there.
After the first round of four cards, dealer deals another round of four cards each and nondealer again plays first. Continue dealing four-card rounds until the pack is depleted, with dealer announcing 'last' on the last round. Whoever makes the last take of the last round gets any cards left on the table.
Play to 21 points or to any other agreed-upon number.
Tips: Keeping track of what's been played -- particularly the spades and points you've taken in -- is critical in Casino.
Until it's been played, a certain amount of tension revolves around the 10, Big Casino. As nondealer, if you have the 10, you risk losing it if you can't take it in. (Dealer will probably save any 10 as the final card of the round.) Beware of building 10s when your own 10 is not the 10.
If you are dealt any of the four aces or the 2 , your best chance of taking them in is through building. Test your opponent's hand with a double build. Suppose you're holding an Ace, a 3, and a 6, and on the table are a 3 and a 5. You'd really like to take the Ace for the point. First you play the 3 on the 3, saying 'Building 6s.' If opponent doesn't take it, on your next play you place you Ace on the 5 to make a double build of 6s -- subsequently picking up the lot with your 6.

You can often rack up more points by concentrating on winning cards and spades rather than on the Big Casino and Little Casino.
As dealer, if you are dealt a face card on the last round, you are virtually guaranteed to get last card, since you play last.
