The Professional Poker Tour
The Professional Texas Hold'em Poker Tour is one such 'freeroll', with entrants being required to qualify through their results in previous tournaments. Sponsorship and broadcast-rights fees fund the prize pools.Freeroll tournaments are not exclusive to texas hold'em poker. Casinos frequently offer them to frequent and/or high-value players in games such as craps, blackjack, video texas hold'em poker and slot machines. Origin of the termMany believe the term comes from early 1950s Las Vegas, when guests would often be given a "free roll" of nickels to play at the slot machines upon check-in. Guests would often ask for their "free rolls" and the words became fused together and expanded to mean any complimentary gaming bonus.
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 online hold'em 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 online hold'em 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.
