GAME has agreed a partnership with BT which will see wireless broadband access provided across its 341 UK stores.
The videogames retailer is aiming to create a new environment for gamers to interact and discover new titles.
It hopes the move will allow GAME to showcase its full range of content both online and in-store, through a multi-channel, multi-platform shopping experience.
Customers will also be able download a free smartphone app in-store - via a QR code - giving them instant access to product reviews, videos, news and special offers.
Martyn Gibbs, Chief Executive at GAME Retail, said the introduction of in-store Wi-Fi signals "a new level of customer experience" and a "major step" towards achieving its vision of delivering excellence for the UK gaming community.
“Just as in the music and home movie market, online has revolutionised the way we discover and access new video games," he stated.
"As a company we are constantly evolving, listening to our customers and adapting our approach to deliver for them."
BT Wi-Fi Chief Executive Andy Baker said the firm was "delighted" to add GAME’s stores to the four million UK hotspots where broadband customers already enjoy free, unlimited BT Wi-Fi.
"In store Wi-Fi will give gamers access to all the information they need to buy there and then," he stated.
