About CoolGames CoolGames is the leading HTML5 games developer and publisher in the world. Alongside developing native quality HTML5 games with high profile IP’s such as Tetris, Pac-Man, Snoopy and Miffy, we also distribute games globally reaching millions of players each month. Our in-house developed title Jewel Academy is the world’s most successful match-3 game ever released in HTML5. BoosterMedia was founded in late 2009. In early 2016 we joined forces with Tingly Games and became what is now CoolGames. We have an ambitious and innovative team with over 50 colleagues from all over the world. Our headquarters and studio are located in the center of Amsterdam, The Netherlands. The company also has an office in Tokyo, Japan, and a senior representative in San Francisco, USA.

With Flash disappearing and the overcrowded app-stores, HTML5 is now one of the fastest growing game platforms around. And as a next step after our single player games, we have started developing multi-player, social and Instant games.
