Red Blob Games is the independent educational website and creative project of Amit Patel, focused on explaining mathematics, algorithms, and computer science through interactive visualizations. Drawing on examples from game development, Patel creates guides that let readers explore concepts by reading, watching, and experimenting. The site covers topics including A* and other pathfinding algorithms, graph theory, procedural map generation, noise, hexagonal grids, geometry, probability, and visibility algorithms. It also offers playable demos and tools, such as terrain and map generators, signed distance field font examples, and procedural graphics experiments.

Red Blob Games provides resources for independent, student, and hobbyist software developers, as well as anyone curious about how algorithms work. Its tutorials and articles are free to access, with no signup or advertisements. The site also shares guidance and code for building interactive tutorials and diagrams, with examples using web technologies and open-source starter projects. Patel has worked on educational games and interactive diagrams, and continues to explore ways to make technical ideas engaging and easier to understand through the web.
