Overview

Kingmaker is a strategic board game set during the Wars of the Roses in 15th-century England. Players control factions of nobles who maneuver across a map of medieval England and Wales, fighting battles, besieging castles, capturing royal heirs, and summoning Parliaments. The goal is to crown and protect the last surviving royal heir as King. The game draws from the historical conflict between the Houses of Lancaster and York.

Components

Setup

  1. Remove all cards and counters marked with an asterisk (*) for the Basic Game.
  2. Shuffle the Crown and Event decks separately. Place the Event deck face-down on the board.
  3. Remove 36 cards from the Crown deck and deal them evenly to all players. Return any remainder to the deck.
  4. Each player arranges their Crown cards:
    • Noble cards placed face-up
    • Title cards allocated one per untitled Noble (extras to Chancery)
    • Office cards allocated one per titled Noble (extras to Chancery)
    • Town, Bishop, Mercenary, and Ship cards distributed freely among Nobles
  5. Place Royal Heir counters at starting locations: Henry VI in London, Margaret of Anjou in Fotheringhay, Edward Prince of Wales in Coventry, Richard Duke of York in York, Edward Earl of March in Harlech, George Duke of Clarence in Cardigan, Richard Duke of Gloucester in Calais.
  6. Place each Noble counter in one of the castles listed on their card.
  7. Place ship counters at their listed ports.

Turn Structure

Each player’s turn has 6 phases in strict order:

  1. Chance Phase — Draw the top Event card and resolve its instructions (affects all players).
  2. Movement Phase — Move all, some, or none of your counters (Nobles move up to 5 squares in any direction including diagonally, subject to terrain).
  3. Combat Phase — Resolve any battles or sieges.
  4. Parliament Phase — The sole King or Chancellor of England may summon Parliament.
  5. Coronation Phase — A senior royal heir in line of succession may be crowned King at a cathedral.
  6. Crown Deck Phase — Draw one card from the Crown deck. Noble cards are played immediately; other cards may be kept hidden and played later.
