Topps Attax is a trading card game brand launched by Topps in March 2009, serving as an umbrella for a family of sport-specific collectible card games built around a common Attax game system. The product line grew directly out of Match Attax, the highly successful Premier League football card game that Topps had introduced in 2006 and which had become the best-selling boys collectible in the UK. By 2009 the Attax platform had expanded to cover multiple sports, with the umbrella name Topps Attax applied to baseball and American football variants for North American markets while sport-specific names (Match Attax, Slam Attax for WWE wrestling, Puck Attax for ice hockey) were used for individual releases. Cards in the system include athlete and team cards with numerical attack and defense ratings, allowing head-to-head play. The brand's rapid growth through 2009 and 2010 reflected a broader shift in the trading card market toward game-playable formats rather than purely collectible sets, and the Attax engine proved adaptable enough to underpin dozens of licensed releases across multiple continents over the following decade.
