A game engine for building and playing online adaptations of board games and card games.

VASSAL is an engine for building and playing Internet-capable versions of turn-based, human-vs-human games. Players move and manipulate game pieces via the mouse while typing accompanying text. Moves can be recorded into a log file and stepped through one at a time for email play. During live Internet play, all moves and text are automatically broadcast to other players in real time. Combining a live VASSAL session with a third-party Internet voice-chat tool (such as NetMeeting or TeamSpeak) allows you to play with people around the world at very close to face-to-face pace.

What distinguishes VASSAL from other board gaming tools?

    • Play in real time over a live Internet connection or via email
    • Switch between email and live play any number of times during the course of a game
    • 100% Java application runs on any platform
    • Intuitive drag-and-drop and menu-driven interface with many keyboard shortcuts
    • Auto-report feature reports customizable messages automatically in response to every move
    • Customizable maps: define the number of map windows, each with its own set of tools. Even define your own icons for the toolbar.
    • Customizable counters: define a different right-click menu, with nested menus, for each counter. Define your own keyboard shortcuts.
    • Customizable help files: define your own HTML-based online help pages. Define your own charts and tables for reference during play. Even write your own interactive tutorials.
    • Advanced counter definitions: rotate to any number of facings, n-sided, combined layers, arbitrary shapes, text labels in customizable fonts and colors, property sheets.
    • Limited information capability: pieces that hide their identity or turn completely invisible. Map windows that can be hidden from other players.
    • Import any GIF/JPG/PNG graphics file for your maps and counters
    • Modular, extensible design with open-source Java code base
