Then: - Choose board dimensions and placement style - Mix familiar and fairy pieces from the shared library - Create new pieces with reusable movement rules - Configure promotion relationships - Arrange the complete starting position - Test the game before saving - Import and export custom games as JSON ORGANIZE YOUR COLLECTION Create named collections from the catalogue, arrange the games you want to revisit, and choose custom artwork for individual entries.

It is designed for curious players, variant collectors, game designers, and anyone who enjoys discovering how a small change in movement can create an entirely new strategy game.
