Emeralds

Emeralds, like all colored gemstones, are graded using four basic parameters – the four Cs of Gemstones: Color, Cut, Clarity and Crystal. The last C, crystal is a synonym that begins with C for transparency or what gemologists call diaphaneity. Before the 20th century, jewelers used the term water as in a gem of the finest water to express the combination of two qualities, color and crystal. Normally, in the grading of colored gemstones, color is by far the most important criterion. However, in the grading of emerald, crystal considered a close second. Both are necessary conditions. A fine emerald must possess not only a pure verdant green hue as described below, but also a high degree of transparency considered a top gem. In the 1960s, the American jewelry industry changed the definition of emerald to include the green vanadium-bearing beryl as emerald. As a result, vanadium emeralds purchased as emeralds in the United States recognized as such in the UK and Europe. In America, the distinction between traditional emeralds and the new vanadium kind reflected in the use of terms such as Colombian Emerald. Scientifically speaking, color divided into three components: hue, saturation and tone. Yellow and blue, the hues found adjacent to green on the spectral color wheel, are the normal secondary hues found in emerald. Emeralds occur in hues ranging from yellow-green to blue-green. The primary hue must be green. Only gems that are medium to dark in tone considered emerald. Light-toned gems known by the species name, green beryl. In addition, the hue must be bright (vivid). Gray is the normal saturation modifier or mask found in emerald. A grayish green hue is a dull green. Emerald tends to have numerous inclusions and surface breaking fissures. Emerald graded by eye. Thus, if an emerald has no visible inclusions to the eye it considered flawless. Stones that lack surface breaking fissures are extremely rare and therefore almost all emeralds are treated, oiled, to enhance the apparent clarity. Eye-clean stones of a vivid primary green hue with no more than 15% of any secondary hue or combination of a medium-dark tone command the highest prices.6 This relative crystal non-uniformity makes emeralds more likely than other gemstones to be cut into cabochons, rather than faceted shapes.

Online bingo is the game of bingo played on the Internet.

Unlike balls used in regular bingo halls, online bingo sites use a random number generator. Most bingo halls also offer links to online poker and casino offerings as the patrons are often in the target market. One notable feature of online bingo is the chat functionality. Bingo sites strive to foster a sense of community and interaction between players as this helps customer retention.

Playing bingo online, players can make use of optional features, which make playing the game easier, such as auto-daub. Auto-daub automatically marks off the numbers on cards as they are called, so players don't have to. Most software providers support other gaming features as Best Card Sorting and Best Card Highlighting where players cards are sorted and highlighted by closest to bingo. Some of these features are designed to free players to enjoy the communal pleasantries of the chat features.

There is variety among the different kinds of bingo games that can be played. For example, some inexpensive game rooms appeal to the player who may want to play for just a 10 cents or 10 pence; some bingo games only allow players to purchase the same amount of cards so they are not competing against the high rollers out there who buy many cards for the same game.

Punto Banco

Playing Baccarat

Baccarat or Punto Banco is usually played in a separate casino area. The playing table is about the size of a craps table with three casino dealers and up to 12 or 14 players. There are just two principal bets to make: banker or player - Banco or Punto, plus the rarely used Standoff. Some casinos let the players deal the cards in turn and others have a casino dealer to deal the cards.

Each player, including the player dealing, may bet on either Punto or Banco but it is customary for the dealer to bet on Banco. Players may opt not to deal, passing the 'Shoe' to the next player. The shoe remains with one player as long as the Bank wins. If Punto wins, the shoe passes on to the next player. Two hands are dealt and you bet which one will win, or that they will tie. It is just like betting on Black or Red at roulette, and the payoff is even money, 1:1 (except for the standoff, which pays 8-1 or 9-1). The only difference between the Banco and Punto bet is a win on Banco will cost you 5% commission or tax levied by the casino - the in-built advantage. The reason for taxing the Banco is because it has been established that over an 8-deck cards play on average the Banco will win three to four hands more than the Punto. Each hand consists of a minimum of two and a maximum of three cards. The person dealing will put two cards, face down, tucked under the shoe, and give the player with the largest bet on Punto the other two cards, face down. The Punto player then looks at the cards and gives them back to the player who is dealing. Then the player who is dealing will turn over the cards of both hands while one of the casino dealers will announce the results and the winner. If either hand has a total of 8 or 9 (nine is the highest), then it is called a 'Natural' and no more cards are dealt. If it is not a natural, then depending on the value of each hand the casino dealer may instruct the card dealer to deal a third card. The decision when to deal a third card follows precise set rules used by all casinos. Once dealing is completed, the hand with the highest count wins. The paying casino dealers will collect the losing bets first and then pay the winning ones. The player who actually deals the cards is not responsible for the payouts. He is just like any other player, playing against the casino.

Baccarat Rules

Baccarat is played from a six-deck or an eight-deck shoe. All face cards and 10s have no value. Cards less than 10 are counted at face value, Aces are worth 1. Suits don't matter. Only single digit values are valid. Any count that reaches a double digit drops the left digit. 15 is counted as 5 and 25 is also counted as 5. To start, the players bet either on Banco or Punto or Standoff. The card dealer gives two cards each; first to the player and then the banker. The object of the game is to bet on the hand that you think will have the highest total value. A third card may be dealt to either or both the player (Punto) and the bank (Banco) based on the following three-card-rules. It is not necessary to learn these rules to play, they are compulsory decisions and therefore automatic. Only on rare occasions a mistake is made: Player's third-card-rule

• If either the player or the bank have a total of 8 or 9 on the first two cards no further cards are drawn. The resulting hand is called a natural and the hand is over.
  
• If the player's total is less than or equal to 5 the player's hand draws a third card.
  
• If the player does not draw a third card, then the bank's hand stands on 6 or more and takes a third card on a total of 5 or less. If the player does take a third card then the Bank's third-card-rule below will determine if the bank takes a third card.
  

Bank's third-card-rules

• If the bank's total is 2 or less then bank draws a card, regardless of what the players third card is.
  
• If the banks total is 3 then the bank draws a third card unless the players third card was an 8.
  
• If the banks total is 4 then the bank draws a third card unless the players third card was a 0, 1, 8, or 9.
  
• If the banks total is 5 then the bank draws a third card if the players third card was 4, 5, 6, or 7.
  
• If the banks total is 6 then the bank draws a third card if the players third card was a 6 or 7.
  
• If the banks total is 7 then the bank stands.
  

House advantage
Banker (Banco) 1.17%
Player (Punto) 1.36%
Tie (Standoff) 14.12% at 8:1 payout

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.

Card Game

A card game is any game using playing cards as the primary device with which the game is played, be they traditional or game-specific. Countless card games exist, including families of related games such as poker. A small number of card games played with traditional decks have formally standardized rules, but most are folk games whose rules vary by region, culture, and person.

Many games that are not generally placed in the family of card games do in fact use cards for some aspect of their gameplay. Similarly, some games that are placed in the card game genre involve a board. The distinction is that the gameplay of a card game primarily depends on the use of the cards by players the board is simply a guide for scorekeeping or for card placement, while board games the principal non-card game genre to use cards generally focus on the players' positions on the board, and use the cards for some secondary purpose.
