JD Wetherspoon has awarded a major two-year deal for the supply of all the amusement machines to its 526 pubs.
Leisure Link will provide AWPs, SWPs, tournament games, video games and other equipment as well as all the pubs' payphones.
It was already a supplier of more than 1,700 entertainment machines to the Wetherspoon chain.
Wetherspoon managing director John Hutson said: "We want to offer our customers the very best in machine entertainment and enable our pubs to be at the forefront of future technological change."
Leisure Link was formed in a management buy-in of Bass Leisure Machines Services and has since bought Stretton Leisure and Maygay.
Managing director Jim O'Halleran said: "We will continue to focus on innovation and product development to improve and provide an enhanced machine offering across Wetherspoon's ever-growing chain."
The Wetherspoon chain originally had a policy of excluding games machines from its outlets, but later reversed this due to consumer demand.
