Thirteen Games is the creator of Nova Island, a free-to-play mobile game built around strategic one-on-one card battles and a colorful science-fiction universe shaped by its players. The game invites players to compete against opponents around the world, climb leaderboards, take on daily single-player challenges, or play matches with friends. Its campaign follows a colorful map where players can meet and unlock eight Pro Characters, each with six unique Superpowers that add variety to tactical play.

Nova Island features a diverse cast, including Flora, Max, Jack, Dr. Boom, Aster, Camille, Slayborg, and Sydney, alongside their distinctive groups of allies. Players can use cards to build strength, launch attacks, and outmaneuver opponents, with each character offering a different strategic flavor. Beyond the game itself, Thirteen Games encourages players to join its Discord community, share experiences, and provide feedback as the world of Nova Island develops. The site also provides access to the game, contact information, press materials, creator assets, and policies covering service and fan content.
