UK betting and gaming business William Hill has awarded an exclusive contract to Inspired Gaming Group for the sole supply of gaming machines to the group's licensed betting offices.

Inspired currently supplies 79 per cent of the gaming machines in William Hill's 2,350 LBOs through new generation Storm cabinets launched in the William Hill estate between August 2009 and March 2010. William Hill is currently conducting a trial of a three-screen version of the Storm cabinet in 100 LBOs, including marketing and rewards functionality.

These cabinets will be rolled out to the remaining 21 per cent of the William Hill estate by the middle of 2012 and discussions are ongoing about future technology innovations. The new exclusive contract extends to 2016. Under the contract, William Hill has retained the flexibility of an option to return to a dual-supply model for a portion of its estate should it consider that to be in its best interests.

Ralph Topping, chief executive of William Hill, said: "William Hill has established a reputation for the best gaming offer on the high street and this change to our machines estate will ensure we can continue to offer market leading technology to our customers."

Luke Alvarez, chief executive of Inspired Gaming Group, added: "We are proud to have been selected by William Hill as exclusive gaming machine supplier, after  four years of head-to-head comparisons."
