An additional four companies have submitted applications for licences to offer fantasy sports contests in Pennsylvania, the state Gambling Control Board (PGCB) has revealed.

With six applications already submitted, ten companies are looking to secure fantasy sports licences in the state.

Until the PGCB has finished assessing each company's application, players in the state will be able to enter paid contests via sites operated by these companies.

The four new applicants are Yahoo Fantasy Sports, Fantasy Draft, Full Time Fantasy Sports, which operates the Scout Fantasy Sports brand, and Sportshub Technologies, which runs the Fanball, CDM Sports, MLF 10s and National Fantasy Championships sites.

They join previous applicants DraftKings, Boom Fantasy,, the Fantasy Football Players Championship, Draft and FanDuel.

FanDuel is currently discussing a potential combination with the US business of Draft's parent company Paddy Power Betfair.

Fantasy sports contests became the first new product regulated under Pennsylvania's gaming expansion legislation when the PGCB enacted regulations for the vertical earlier this month.

Contests are restricted to those aged 18 and over. Operators are also required to pay a 15 per cent tax on revenue generated from fantasy contests, effective April 28th.
