Bubblegum Interactive has launched its first line of game cards into UK retail.
Cards for Space Heroes Universe, a virtual world for kids, have been rolled out to over 480 Sainsbury's across the UK. More retailers will follow, including Asda.
Every game card purchased in Sainsbury's will provide players with exclusive, rare items within the game, including a turbo-charged starlet, a bomber jacket and a rare pet kritter.
Sainsbury's is promoting this through point of sale 'wobblers'.
Paul Gray of Bubblegum Interactive said: "The UK is one of our strongest markets and our fans have been eagerly awaiting the game card launch.
"We're excited to give them a convenient new way to pay for membership."
