"Robbo" is a classic brain and logical/puzzle game that was originally released for Atari XL/XE computers in 1989. Developed and published by LK Avalon, the game was created by Janusz Pelc, showcasing both his programming and graphic design skills. In "Robbo," players navigate a robot through various levels, solving puzzles to progress. The game was notable for its engaging gameplay and for being a significant success in Poland, where it gained considerable popularity. Despite its success, the game's financial gains were limited due to the lack of legal frameworks against software piracy in Poland at the time​​.

The game's release was accompanied by a unique contest, where the first five players to send a description of the game's ending to Avalon were promised a copy of the next game released by the company. This contest attracted thousands of submissions​​. Following the initial release, an editor tool named "Robbo Konstruktor" was developed by Pelc and released by Avalon in 1990, allowing players to create new levels for the game​​.

"Robbo" was later ported to various other platforms, including DOS PCs, with enhanced graphics and additional levels, making the DOS version feature a total of 60 levels. This version was released in Poland in 1993 by XLand, and also made its way to the American market through Epic MegaGames under the title "Adventures of Robbo"​​.

Further adaptations and unofficial versions of "Robbo" have appeared over the years, including a mobile phone version, a multiplatform port named GNU Robbo, and even a version for Google Android named Robboid available on Google Play​​.

The game maintains a 7.9/10 rating on Atarimania, reflecting its lasting appeal and the fondness that gamers have for this puzzle-solving adventure​​. For fans of classic Atari games or those interested in the history of video games, "Robbo" represents a notable piece of Polish gaming history, demonstrating the creativity and skill of its developer, Janusz Pelc.
