GitGuessr is a game designed to test and improve code reading skills by placing players in random locations within real GitHub repositories where certain lines of code are hidden. The main purpose is to help developers practice navigating and understanding unfamiliar codebases efficiently.

Players are challenged to fill in missing lines of code as quickly as possible, requiring them to comprehend the surrounding code context. The game offers well-balanced challenges in Python, TypeScript, and JavaScript, which are the top three languages on GitHub. Users can also create their own code maps from favorite languages or repositories for community play.

The game operates similarly to GeoGuessr but for code, dropping players into authentic code snippets from public repositories. This approach emphasizes quick orientation and comprehension rather than writing code from scratch.

GitGuessr trains a key programming skill essential in the AI era: the ability to quickly understand unfamiliar code that might be generated by large language models. It provides a fun yet serious way to enhance code reading proficiency.

The target audience includes software engineers, developers, and programming enthusiasts looking to improve their code navigation skills. It supports popular programming languages and integrates with real GitHub repositories for authentic coding challenges.
