VASSAL

VASSAL is a digital board game engine for creating and playing adaptations of tabletop board games and card games. It allows players to participate in games online in real time or asynchronously through email. Thousands of community-created game modules provide virtual boards, playing pieces, and game-specific components. Users can load existing modules or create their own using the integrated module editor. Its interface supports moving pieces, managing maps, and recording gameplay actions. Game logs allow players to review moves and continue asynchronous matches. The system also supports dice rolling, counters, and configurable game components. VASSAL runs on Windows, macOS, and Linux using Java, making it suitable for tabletop gaming communities and game designers.
