Playing Cards

A playing card is a piece of specially prepared heavy paper, thin cardboard, or thin plastic, figured with distinguishing motifs and used as one of a set for playing card games. Playing cards are typically palm-sized for convenient handling.

A complete set of cards is called a pack or deck, and the subset of cards held at one time by a player during a game is commonly called a hand. A deck of cards may be used for playing a great variety of card games, some of which may also incorporate gambling. Because playing cards are both standardized and commonly available, they are often adapted for other uses, such as magic tricks, cartomancy, or building a house of cards.

The front or face of each card carries markings that distinguish it from the other cards in the deck and determine its use under the rules of the game being played. The back of each card is identical for all cards in any particular deck, and usually of a single color or formalized design. Usually every card will be smooth however some decks have braille to allow blind people to read the card number and suit. The back of playing cards is sometimes used for advertising. For most games, the cards are assembled into a deck, and their order is randomized by shuffling.

Progressive Jackpot

A progressive jackpot is a jackpot highest payoff for a gaming machine usually a slot machine or video poker machine where the value of the jackpot increases a small amount for every game played. Normally multiple machines are linked together to form one large progressive jackpot that grows more quickly because multiple players are contributing to the jackpot at the same time.

The amount of the jackpot is shown on a meter as a money value. Usually the jackpot can only be won by winning the combination with the highest payoff, e.g. a royal flush at a video poker game, or five of the most valuable symbols lemons, cherries, alligators, etc on a slot machine. Once a player wins the jackpot, the jackpot resets to a preset minimum level.

The amount on the jackpot progresses increases a small amount for every play on a connected machine. The amount that the jackpot advances by is set by the casino the house. For example, on a machine whose house edge is 5%, a generous jackpot contribution might be 1% one fifth of the expected profit. The house is prepared to contribute some of the profit of a jackpot linked machine because players are attracted by the:

Relative novelty of progressive jackpots generally, only a small fraction of the house's gaming machines will be connected to a progressive jackpot

Constantly changing meter, often displayed on large LED or LCD displays

Large amount of the jackpot, which eventually motivates more players to play the game

Usually only players who wager the maximum number of credits per play qualify to win the jackpot. All wagers, whether or not they are maximum credit bets, contribute to the jackpot though. As a result, a game which requires a 10 credit wager to qualify for the progressive jackpot will tend to have the progressive jackpot rise to higher levels relative to its break-even level than a game that requires only a 5 credit wager to qualify.

In some games such as video poker, it is possible to compute an optimal playing strategy based on the frequency for each payoff versus the odds of hitting that payoff. Since the jackpot of a progressive video poker game is constantly growing, it eventually can reach a break-even point where the machine becomes a positive expectation bet for the player.

When the progressive jackpot is less than the break-even point, there is a negative expected value house edge for all players.

In the long run, with optimal strategy, a video poker player can make a profit, although the long run is generally longer than most people think. Several tens of thousands of plays.

It is worthwhile to note that a break-even point cannot be easily calculated on a slot machine game, because the payback percentage for the game is normally unknown to the player. The break-even point in video poker can be calculated because the payback percentage for the game is a function of the paybacks and odds of the poker hands, which is based on a standard 52 card deck. The return of a slot machine is based on the published paytable, but also on the normally unpublished reels. For a five reel slot machine, the player would need to know each symbol on each of the slot machine's five reels, in order to calculate the odds. For a three reel slot, the reels are normally weighted, and this would not be possible. However, in some circumstances the manufacturer may publish the payout of their machines.

Brick and Mortar

Brick and mortar bricks and mortar or B&M in its simplest usage is used to describe the physical presence of a buildings or other structure. It's a concept usually referred to in business, which applies to the physical location for a business or organization.

The term brick and mortar business bricks and mortar business or B&M business is often used to refer to a company that possesses a building or store for operations. The name is a metonym derived from the traditional building materials associated with physical buildings — bricks and mortar. Its first use was in 1992.

More specifically, in the jargon of online ecommerce businesses, brick and mortar businesses are companies that have a physical presence and offer face-to-face customer experiences. This term is usually used to contrast with a transitory business or an internet-only presence, such as an online shop, which have no physical presence for shoppers to visit and buy from directly, though such online businesses normally have non-public physical facilities from which they either run business operations from, and/or warehousing for mass physical product storage and distribution.

An example would be the movie-rental shop Blockbuster Video, which has physical stores and is in competition with the newer online rental services offered by Netflix. In this sense, the term is also a retronym in that all stores had a physical presence before the advent of the Internet, making such a term unnecessary.

A comparable term in the United Kingdom is High Street shops, although the phrase bricks and mortar business is also commonly used.
