Overview

Build a board, paint terrain, design piece movement, place the starting army and play it. Includes a full rules engine, legal-move hints, animated captures, portals, explosions and a generated rulebook that explains whatever you invented.

What is inside

  • A human-readable rulebook is generated from the variant you just built.
  • Effects include swapping on capture, explosions with radius and piece spawning.
  • Turn view rotates the board for pass-and-play on one screen.
