Write simple functions that describe how the game state changes when a particular move is made. This is automatically converted into a working game complete with online multiplayer features, all without requiring you to write a single line of networking or database handling code.


  • State Management: Game state is managed seamlessly across clients, server and storage automatically.
  • Multiplayer: Game state is kept in sync in realtime and across platforms.
  • AI: Automatically generated bots that can play your game.
  • Game Phases: with different game rules and turn orders per phase.
  • Prototyping: Interface to simulate moves even before you render the game.
  • Logs: Game logs with the ability to time travel (viewing the board at an earlier state).
  • View-layer Agnostic: Use the vanilla JS client or the bindings for React / React Native.
  • Component Toolkit: Components for hex grids, cards, tokens etc.
  • Extendable: Plugin system that allows creating new abstractions.
