This is an early playable build of the rules in the Chirality rulebook and may differ from final balance.
Game Log
How This Demo Plays
The Board
A Penrose rosette of Thick (gold) and Thin (mint) rhombi. Up to five Gates sit on the outer fringe; authored boards with fewer valid Gates automatically lower the player limit. Each valid Gate is a four-tile formation of two outward-jutting Thin tiles flanking two Thick tiles. The central Throne is a five-Thick Star at the rosette's center, outlined gold.
Setup
Pick a setup mode in the HUD:
- 8/8 (default, 2P): each player claims two Gates, auto-filling 4 pieces each. 8 reserves.
- 4/12: each claims one Gate. 12 reserves.
- 1-piece: each places one piece on any Gate tile. 15 reserves.
- Inner Garrison: each garrisons one Inner Ring Star with 5 pieces. 11 reserves.
Movement
A piece's options come from the tile it stands on:
- Piece on a Thick tile → moves to any edge-adjacent empty Thin tile.
- Piece on a Thin tile → moves to any edge- or vertex-adjacent empty Thick tile.
Or Muster a reserve onto an empty tile of a Gate you currently occupy. A Garrison on an Inner Ring Star unlocks Remote-Muster to any Gate on the same half of the board (Thick tiles only).
Capture
After every action, captures resolve automatically:
- A Thin piece is captured by 1 enemy Thick neighbor across an edge.
- A Thick piece is captured by 2+ enemy Thin neighbors across an edge or vertex.
- A piece on a Throne tile is exposed: just 1 enemy attacker captures it.
- Garrison occupants are uncapturable. By default, each Garrison Moat is the original board-defined moat ring; the optional Expanded Moats toggle adds Thin tiles sharing a full edge with that original ring. Moats auto-capture enemies inside them at end of turn.
- Initiative: the active player resolves their captures first. A piece that moves into an attacked tile dies if its move didn't remove all the attackers; if the move killed them all, the piece survives.
Winning
Occupy all five Throne tiles (a hard win, since Throne pieces are exposed and easily attacked), or eliminate every opposing army. Last surviving player wins.
HUD Options
The HUD lets you pick board variant (the default board + 14 authored variants, or Random), player count (2–5 where the selected board supports it), setup mode, Blitz (2 actions per turn), optional Expanded Moats test mode, and assign each seat as Human or Klein.
