Chirality

The Chiral Strategy Game. A two-player abstract strategy game on a Penrose rhombus board. Pass the device between turns.
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. Five Gates sit on the outer fringe: each 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. Garrison 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 (default + 25 generated Penrose-legal variants, or Random), player count (2–5), setup mode, Blitz (2 actions per turn), and assign each seat as Human or AI.
