  • 15 Catastrophe cards
  • 28 Age cards
  • Gene Pool cards (1 per player)
  • Trait cards (various colors and effects)

Optional Expansions:

  • Meaning of Life
  • Techlings Attachments

Setup

  1. Separate Cards
    • Remove the Birth of Life and Catastrophe cards from the Age deck.
    • Shuffle the remaining 28 Age cards and create 3 piles of 3 Age cards each, face down. Set aside any remaining Ages.
    • Shuffle Catastrophes and deal 1 random Catastrophe into each pile. Shuffle each pile individually.
    • Stack the 3 piles together, then place the Birth of Life card on top. Place the Age pile in the center.
  2. Gene Pools
    • Each player chooses a Gene Pool card (pick your favorite color). Place it in front of you with 5 facing up. This represents your hand size target for stabilizing each turn.
  3. Trait Cards
    • Shuffle the Trait deck. Deal 5 traits to each player. Place the remaining deck next to the Age pile.

Objective

The aim is to score the most points before the world ends, using traits, Gene Pool management, and strategic play through the ages.


Game Structure

Ages

  • The game is played in rounds called ages.
  • The first player, located to the left of the dealer, flips an Age card from the pile to start a round.
  • Age cards may contain:
    • One-time effects: Apply immediately in turn order before normal turns.
    • Rule effects: Persist for the entire round (e.g., “Players cannot play green traits”), but reset in the next age.

Taking a Turn

  • Move clockwise, following any current Age effects.
  • On your turn:
    1. Play 1 trait from your hand face up in front of you (your trait pile).
    2. Resolve any effects on the trait card.
    3. Stabilize: Your hand must match your Gene Pool value.
      • If your hand < Gene Pool → draw cards
      • If your hand > Gene Pool → discard cards
      • If your hand = Gene Pool → do nothing

Note: Only draw or discard during stabilization, even if your Gene Pool changes mid-turn.

Catastrophes

  • Catastrophes are special Age cards with lasting effects.
  • When drawn:
    • First player rotates 1 position left.
    • Gene Pool Effect: Adjusts all players’ Gene Pools permanently.
    • Catastrophic Effect: Applies immediately for that round only.
    • World’s End Effect: Ignored until the third catastrophe, which ends the game.

World’s End

  • When the third catastrophe is revealed:
    1. Apply Gene Pool and Catastrophic effects.
    2. Resolve World’s End symbols on trait cards.
    3. Calculate final scores.

Scoring

  1. Apply any World’s End points.
  2. Sum the face value of traits in your pile.
  3. Add any bonuses/modifiers (look for the drop-of-life symbol).

Ties: Draw a card from the deck and use its face value to break ties.


Gene Pool Rules

  • Minimum: 1, Maximum: 8.
  • Stabilize at the end of your turn to match your Gene Pool.
  • Catastrophes and traits can increase or decrease your Gene Pool; adjust the card but don’t draw/discard until stabilizing.

Dominant Traits

  • Gold border and star.
  • Cannot be removed, swapped, stolen, or discarded.
  • Only one exception: “Birth of a Hero” Age allows 3 dominant traits.

Color & Trait Mechanics

  • Colors: Blue (defense), Green (growth), Purple (sneaky), Red (risk/reward), Grey (colorless).
  • Dual color traits count as both colors.
  • If you cannot play a trait, draw 3 cards and skip your turn. Optional: discard all cards and draw 3. Do not stabilize this turn.

Expansions

Meaning of Life
  • Gives traits hidden objectives worth bonus points.
  • Setup: Deal 2 cards face down per player; keep 1, discard the other.
  • Score bonuses at the end of the game.
Techlings: Attachments
  • Certain traits may attach to host traits.
  • Host traits cannot already have attachments or be dominant.
  • Attachments follow their host if swapped/stolen, but are discarded if the host leaves your trait pile.

Game Variants

  • Stunted Growth: Skip turns on catastrophes for shorter games.
  • Prosperous World: Use 3 piles of 4 ages with catastrophes for longer games.
  • Intelligent Design: Draft traits before starting to customize hands.
  • Rapid Succession: Rotate first player every age.
  • Autocratic Rule: Keep first player static.

FAQ

Can I ignore a card effect?

Only if it’s optional; required effects must be followed unless restricted by another rule.

How do attachments work?

Attach to host traits. They move with the host during swaps, but are discarded if the host leaves your trait pile.

What happens during a tie?

Draw the top card of the deck; the highest face value wins.
