QA Tester

By March 2, 2020Jobs

With the app-stores overcrowded, cloud-gaming is the next big thing and HTML5 is now one of the fastest growing cloud-game technologies. CoolGames has been a front-runner in developing and publishing high-quality HTML5 games since 2010, such as Angry Birds, Battleship and Daily Sudoku, which is now the #1 sudoku game on Facebook. Our games can be found within numerous social platforms & messaging apps, as well as on game websites and media channels worldwide. They combine high quality core gameplay and a well-designed metagame for long-term retention with social- or multi-player features for viral distribution and discoverability. And monetization is often a mixture between ads, IAP and subscription models.
