Overview

Ancestree is a tile-drafting game where players compete to build the best family tree over three rounds. Each round, players simultaneously select ancestor tiles from a shared hand, place them into their growing family tree, and pass the remaining tiles to a neighbor. Points are scored after each round for dynasty majorities, coins, and at the end of the game for marriages. The player with the most points wins.

Components

Setup

  1. Shuffle all Ancestor tiles face-down.
  2. Deal 6 tiles to each player as their starting hand.
  3. Place the scoring tokens and marriage reference within reach.
  4. Determine first player or play simultaneously.

Turn Structure

Each round proceeds as follows:

  1. Select: All players simultaneously choose 1 tile from their hand to play into their family tree.
  2. Place: All players simultaneously place their chosen tile, connecting it to their existing tree via leaves or hearts.
  3. Pass: Each player passes their remaining hand to the player on their left (rounds 1 and 3) or right (round 2).
  4. Repeat: Continue selecting, placing, and passing until 5 tiles have been played. The 6th (last) tile in each hand is discarded.
  5. Score the round: Evaluate dynasties and coins (see Scoring).
  6. New round: Deal a new hand of 6 tiles to each player. Play three rounds total.

Actions

Tile Placement

Dynasty Comparison

After each round, for each of the clan types, compare the length of your longest connected chain of that clan to the corresponding chains of the players sitting immediately to your left and right. If your chain is longer, you win a dynasty token from that comparison.

Scoring / Victory Conditions

Points are accumulated from three sources:

Dynasties (scored each round)

Coins (scored each round)

Marriages (scored at end of game only)

The player with the highest total score wins.
