PLAY AND STUDY

- Play complete local pass-and-play Modern Chess

- Inspect piece names and movement descriptions

- Show legal destinations while exploring a position

- Rotate, reset, and undo supported board actions

- See promotions and variant-specific board layouts

Most historical and large variants are presented as interactive explorers. Their published setups and ordinary movement are modeled, while complex tournament rules that are not yet enforced are clearly identified in each game guide.

CREATE CUSTOM CHESS VARIANTS

Start with a blank board or remix an included game. 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.

Chessorium works locally and requires no account. 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.
