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.
  • Cross-platform Multiplayer: All clients (Web / Android / iOS) are kept in sync in realtime.
  • Automatic AI: MCTS-based bots with options to customize.
  • Game Phases: with different game rules (including custom turn orders) per phase.
  • Prototyping: Debugging 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: Vanilla JS client with bindings for React / React Native.
  • Component Toolkit: Components for hex grids, cards, tokens.
  • Extendable: Subsystems (storage, networking etc.) can be replaced with custom implementations.
