Favorite Coolmath Games: Clicker Heroes, Block the Pig, Tube Master
Jon is a strategy game fanatic - his favorite games are open-ended puzzles with strategic, complex systems and creative solutions. He loves that games allow anyone to share in unique experiences, like designing a subway system in Mini Metro: London or building a civilization in Pre-Civilization Bronze Age. He has been helping discover and design games that make you think for Coolmath since 2014.
In his free time, Jon enjoys biking, playing board games, card games, Nintendo, Xbox and PC games. In past lives he has helped design board games and card games, including the Chaotic Trading Card Game and the Twilight movie (yes, that Twilight) board game series.
Jon is a graduate of NYU’s Stern School of Business and is deeply passionate about using games as a way to help people think, learn, and grow. His accomplishments in the web gaming space have given him opportunities to share his insights as a speaker and panelist at industry events such as GDC, Gamescom and Pocket Gamer Connects.
