Game has beaten its target for openings this year, and is positioning for the launch of the next generation of consoles.
The retailer acquired 17 former Sanity shops earlier this month. These, combined with the opening of outlets in Madrid's M40 shopping complex and in London's Islington on April 22 and 23 respectively, take Game's store total to 515 across six countries.
A Game spokesman said: 'Over the past four years, video gaming has become mass-market. We need to be in a position today to occupy as much space as possible to make the most of that now, and for the next two years.'
He added that the next generation of Xbox, PlayStation and GameCube consoles will be released over the next two years.
Game had set itself the goal of 500 outlets by the middle of this year, and is confident of having 600 shops in its existing markets by February 2005.
