About Rebellious Software
Rebellious Software is an independent Bulgarian game development and software engineering company based in Sofia. Founded in 2014 and legally incorporated in 2015, it develops original games for PC and mobile alongside custom software and systems design work. Its game portfolio spans digital collectible card games, turn-based strategy and mobile titles that combine role-playing mechanics with casual casino formats.
Games and development
The studio’s early project, Animals at War, served as an experimental learning project built around turn-based card play for web and mobile. That experience informed the development of World of Myths, its flagship online collectible card game, released on Steam on May 30, 2019.
World of Myths draws on Greek, Norse, Japanese and Egyptian mythology. Its battles use groups of units to attack and defend, giving the game a different tactical structure from card games built around individual unit exchanges. Competitive play, multiplayer networking and strategy systems are central elements of the studio’s reported capabilities.
In 2020, Rebellious Software began developing Rumble Rebels, a mobile game combining idle RPG progression with casual casino mechanics. Its subsequent mobile work includes High Hand Heroes, described as a mythological battle RPG combining poker, solitaire and roguelike elements. These projects extend the studio’s work beyond its early card-game focus into hybrid mobile formats.
Engineering and collaboration
Alongside its own intellectual property, the company offers full-cycle game development, covering game design, client and server engineering, and 2D and 3D art and animation. Its capabilities also include application development for iOS and Android, cross-platform multiplayer systems and custom software architecture.
Rebellious Software works with external partners through co-development and work-for-hire arrangements, including collaborations with US game studios. It also maintains a commercial software engineering practice offering digital systems consulting and computer systems design, combining its entertainment projects with broader technical development work.
