The Game Graph Gym (GGG) is a framework for implementing and benchmarking solvers for games on graphs. The architecture consists of:

• Core Library: a C++20 library that provides templates for defining custom graph types, parsers, and generic algorithms.
• Graphs and Solvers: for some well-known types of games (buechi, parity, mean-payoff, and stochastic discounted)
• Commandline Tools: for using solvers with uniform CLI interface, random game generators, and convenience scripts for benchmarking.
