Online poker is the game of poker played over the Internet. It has been partly responsible for a dramatic increase in the number of poker players worldwide. In 2005, revenues from online poker were estimated at US$ 200 million per month.

Overview

Traditional (or "brick and mortar", B&M, live) venues for playing poker, such as casinos and poker rooms, may be intimidating for novice players and are often located in geographically disparate locations. Also, brick and mortar casinos are reluctant to promote poker because it is difficult for them to profit from it. Though the rake, or time charge, of traditional casinos is often high, the opportunity costs of running a poker room are even higher. Brick and mortar casinos often make much more money by removing poker rooms and adding more slot machines.

Online venues, by contrast, are dramatically cheaper because they have much smaller overhead costs. For example, adding another table does not take up valuable space like it would for a brick and mortar casino. Online poker rooms also allow the players to play for low stakes (as low as 2¢) and often offer poker freeroll tournaments (where there is no entry fee), attracting beginners.

Online venues may be more vulnerable to certain types of fraud, especially collusion between players. However, they have collusion detection abilities that do not exist in brick and mortar casinos. For example, online poker room security employees can look at the hand history of the cards previously played by any player on the site, making patterns of behavior easier to detect than in a casino where colluding players can simply fold their hands without anyone ever knowing the strength of their holding. Online poker rooms also check players' IP addresses in order to prevent players at the same household or at known open proxy servers from playing on the same tables.

Free poker online was played as early as the late 1990s in the form of IRC poker. Shortly thereafter Planet Poker was the first online cardroom to offer real money games. Author Mike Caro was one of the founders and the "face" of Planet Poker.

The major online poker sites offer varying features to entice new players. One common feature is to offer tournaments called satellites by which the winners gain entry to real-life poker tournaments. It was through one such tournament on PokerStars that Chris Moneymaker won his entry to the 2003 World Series of Poker. He went on to win the main event causing shock in the poker world. The 2004 World Series featured three times as many players as in 2003. At least four players in the WSOP final table won their entry through an online cardroom. Like Moneymaker, 2004 winner Greg "Fossilman" Raymer also won his entry at the PokerStars online cardroom.

In October 2004, Sportingbet Plc, at the time the world's largest publicly traded online gaming company (SBT.L), announced the acquisition of ParadisePoker.com, one of the online poker industry's first and largest cardrooms. The $340 million dollar acquisition marked the first time an online cardroom was owned by a public company. Since then, several other cardroom parent companies have gone public.

In June 2005, PartyGaming, the parent company of the then largest online cardroom, PartyPoker, went public on the London Stock Exchange, achieving an initial public offering market value in excess of $8 billion dollars. At the time of the IPO, ninety-two percent of Party Gaming's income came from poker operations.

The market appears to be currently in a consolidation phase. In early 2006, PartyGaming moved to acquire EmpirePoker.com from Empire Online. Later in the year, bwin, an Austrian based online gambling company, acquired PokerRoom.com. Other poker rooms such as PokerStars and Poker.com that were rumored to be exploring initial public offerings have postponed them.

As of March 2008, there are fewer than forty stand-alone cardrooms and poker networks with detectable levels of traffic. There are more than 600 independent doorways into the group of network sites.

Legality

From a legal perspective, online poker may differ in some ways from online casino gambling. However, many of the same issues do apply. For a discussion of the legality of online gambling in general, see online gambling.

Online poker is legal and regulated in many countries including several nations in and around the Caribbean Sea, and most notably the United Kingdom.

In the United States, the North Dakota House of Representatives passed a bill in February 2005 to legalize and regulate online poker and online poker cardroom operators in the state. The legislation required that online poker operations would have to physically locate their entire operations in the state. Testifying before the state Senate Judiciary committee, Nigel Payne, CEO of Sportingbet and owner of Paradise Poker, pledged to relocate to the state if the bill became law.

How online poker rooms profit

Typically, online poker rooms generate the bulk of their revenue via four methods. First, there is the rake. Rake is collected from most real money ring game pots. The rake is normally calculated as a percentage of the pot based on a sliding scale and capped at some maximum fee. Each online poker room determines its own rake structure.

Second, pre-scheduled multi-table and impromptu sit-and-go tournaments are not raked, but rather an entry fee around ten percent of the tournament entry fee is added to the cost of the tournament.

Integrity and fairness

As with other forms of online gambling, many critics question whether the operators of such games—especially those located in jurisdictions separate from most of their players—might be engaging in fraud themselves.

Internet discussion forums are rife with allegations of non-random card dealing, possibly to favour house-employed players or "bots" (poker-playing software disguised as a human opponent), or to give multiple players good hands thus increasing the bets and the rake, or simply to prevent new players from losing so quickly that they become discouraged. However, there is little more than anecdotal evidence to support such claims, and others argue that the rake is sufficiently large that such abuses would be unnecessary and foolish. Many claim to see lots of "bad beats" with large hands pitted against others all too often at a rate that seems to be a lot more common than in live games. This might actually be caused by the fact that online cardrooms deal more hands per hour. Since online players get to see more hands, their likelihood of seeing more improbable bad beats or randomly large pots is also increased

Differences compared to conventional poker

There are substantial differences between online poker gaming and conventional, in-person gaming.

One obvious difference is that players do not sit right across from each other, removing any ability to observe others' reactions and body language. Instead, online poker players learn to focus more keenly on betting patterns, reaction time, speed of play, use of check boxes/auto plays, opponents' fold/flop percentages, chat box, waiting for the big blind, beginners' tells, and other behavior tells that are not physical in nature. Since poker is a game that requires adaptability, successful online players learn to master the new frontiers of their surroundings.

Another less obvious difference is the rate of play. In brick and mortar casinos the dealer has to collect the cards, shuffle, and deal them after every hand. Due to this and other delays common in offline casinos, the average rate of play is around thirty hands per hour. However, online casinos do not have these delays. The dealing and shuffling are instant, there are no delays relating to counting chips (for a split pot), and on average the play is faster due to "auto-action" buttons (where the player selects his action before his turn). It is not uncommon for an online poker table to average ninety to one hundred hands per hour.

Bonuses

Many online poker sites offer incentives to players in the form of bonuses.[18][19] Usually the bonuses are given after a certain number of raked hands are played. For example, a site may offer a player who deposits $100 a bonus of $50 once he plays 500 raked hands. A poker player who can at least break even can become a long-term winner by playing with poker bonuses. A winning poker player can add to their winnings with the use of bonuses.[20]

In addition, several online cardrooms employ VIP Managers to develop VIP programs to reward regular players and additional bonuses exist for players who wish to top-up their accounts. These are known as reload bonuses.

Online poker portals and forums

Online poker portals are websites offering poker-related content. Examples of such content could be news, tournament results, strategy articles, poker software, or reviews of online poker cardrooms. Some portals have a considerable amount of content, while others attempt to act as mere conduits to other sites, where actual gambling games are offered. Poker forums exist that discuss poker strategy, cardroom information, gambling news, and other topics.
