Overview

Antler Island is a strategy game for 3-4 players set during the rutting season. Each player controls a stag on a multi-level island, competing to mate with the most does while growing antlers, eating food, and fighting rival stags. The game ends when any stag reaches 12 (3 players) or 10 (4 players) on the doe track, and the player with the most points wins.

Components

Setup

  1. For 3 players, place the 3-player overlay on the board. Attach feet to island layers and place on the board.
  2. The player with the most money is the starting player.
  3. Each player takes a control mat, places 2 antler pieces on their stag’s head, and takes a set of control tiles (1, 2, 3, X, blank).
  4. Place 11 (3 players) or 14 (4 players) doeples in the reserve.
  5. Separate a starting pile of food tokens: 9 for 3 players (5x value-1, 4x value-2) or 12 for 4 players (6x value-1, 6x value-2). Keep face down.
  6. Each player draws 1 food token from the starting pile, kept face down at the bottom of their control mat.
  7. Roll the die for color; starting player places their stag on a matching outside space. Other players place clockwise on the next available matching space.
  8. Roll again (different color); place 1 food token face down on each outside space of that color.
  9. Place one doe on each empty space except wetland and centre spaces.
  10. Shuffle wily tiles face down; flip the top one face up beside the pile.

Turn Structure

Each round:

  1. Action Planning: All players simultaneously place their 5 control tiles (1, 2, 3, X, blank) face down next to actions on their control mat. The blank is a dummy.
  2. Action Resolution: Starting with the starting player and going clockwise, each player reveals and executes one action. Players reveal either their lowest available numbered tile or their X tile. Play continues around the table until all 4 actions per player are resolved.
  3. New Round Setup: Pass starting player clockwise. Move all does one space uphill. Roll die and place food on matching outer spaces (max 2 food per space). Roll die and place sets of 3 (3 players) or 4 (4 players) does from reserve onto matching outer spaces (max 2 sets per round).

Actions

Move: Move your stag to one adjacent space. Stags cannot enter wetland/marsh spaces. Moving into a space with another stag triggers a fight.

Eat: Take ALL food tokens from your space (up to your limit of 5 total). Food tokens remain hidden.

Rut: Remove 1 doe from your space to the reserve. Advance 1 on the doe track. When any stag reaches 12 (3 players) or 10 (4 players), the current round is the final round.

Grow Antlers: Cash in any number of food tokens. Add their values together, divide by 2 (round down) to get antler pieces gained. Exception: cashing in a single token always yields 1 antler piece. Reaching an even number of antlers (4, 6, 8, etc.) for the first time earns a wily tile.

Scoring / Victory Conditions

Game End: When any stag reaches 12 (3 players) or 10 (4 players) on the doe track, finish the current round.

Mandatory Fight Requirement: A player who has never won a fight scores zero points and automatically loses.

Points:

Tiebreakers (in order): Largest antlers, highest on island, food token value total, player height.
