Overview

Kingdom Builder is a territory-building game where players place settlements on a modular board to create their own kingdoms. Three randomly drawn Kingdom Builder cards define the scoring conditions for each game, ensuring high replayability. The player who earns the most gold wins.

Components

Terrain Types

Buildable (5): Grass, Canyon, Desert, Flower Field, Forest Not buildable (4): Mountain, Water, Castle, Location

Setup

  1. Select any 4 of the 8 board sections; assemble into a rectangular game board.
  2. Place matching location tile summaries next to board sections.
  3. Place 2 corresponding location tiles on each location hex.
  4. Shuffle terrain cards into a face-down draw pile.
  5. Shuffle Kingdom Builder cards, draw 3, place face-up beside the board.
  6. Each player takes 40 settlements in their color and 1 gold marker.
  7. Each player draws 1 terrain card (keep hidden).
  8. Flip an unused board section to show the gold score track. Each player places their gold marker on the black (0) space.
  9. Oldest player receives start player tile and goes first.

Turn Structure

Each turn, the active player:

  1. Play terrain card face-up.
  2. Build 3 settlements (mandatory action) on unoccupied hexes matching the terrain type of the played card, following building rules.
  3. Perform extra actions (optional) — from collected location tiles. Each extra action may be done once per turn, before or after the mandatory action.
  4. Discard terrain card to the discard pile; draw a new terrain card.

The 3 mandatory settlements must be built one at a time, sequentially.

Actions

Building Rules (apply to ALL settlements, mandatory and extra)

  1. Exactly one settlement per hex.
  2. Only build on the 5 buildable terrain types.
  3. Must build adjacent to at least one of your own existing settlements, if possible. If not possible:
    • Mandatory action or Oracle/Barn: choose a hex of the played terrain card type.
    • Oasis/Farm/Harbor: choose a hex of the required terrain type.
    • Tower: choose any suitable hex at the board edge.

Location Tile Extra Actions

Gained by building a settlement adjacent to a location hex (take one tile immediately; max one per location). A player keeps a tile as long as at least one of their settlements is adjacent to that location. Used tiles are flipped to indicate use; flipped back after your turn.

Location Action
Oracle Build 1 additional settlement on the same terrain type as your played card. Adjacent if possible.
Farm Build 1 settlement on a Grass hex. Adjacent if possible. Skip if no unoccupied Grass.
Oasis Build 1 settlement on a Desert hex. Adjacent if possible. Skip if no unoccupied Desert.
Tavern Build 1 settlement at one end of a line of 3+ of your own settlements (horizontal or diagonal). Must be a buildable hex.
Tower Build 1 settlement at the edge of the game board on any buildable terrain. Adjacent if possible.
Barn Move 1 of your settlements to a hex of the same terrain type as your played card. Adjacent if possible.
Paddock Move 1 of your settlements exactly 2 hexes in a straight line (any direction). May jump over any terrain or settlements. Building rule 3 does not apply.
Harbor Move 1 of your settlements to a Water hex. Adjacent if possible. Only way to build on water.

Scoring / Victory Conditions

End-game trigger: When any player places their last settlement, the current round finishes (through the player to the right of the start player).

Final Scoring:

  1. Evaluate each of the 3 Kingdom Builder cards for every player.
  2. Each Castle hex adjacent to at least one of your settlements earns 3 gold (regardless of how many settlements are adjacent).
  3. Total gold is recorded on the score track.

Winner: Most gold. Ties share the victory.

Kingdom Builder Card Examples

| Card | Scoring Condition | |——|——————-| | Fishermen | Gold for settlements adjacent to water hexes | | Knights | Gold for building longest horizontal line of settlements | | Merchants | Gold for settlements connecting location hexes | | Farmers | Gold based on the sector with your fewest settlements (must have at least 1 in each sector) |

(Exact scoring varies by card — 10 different cards exist, 3 used per game.)
