Solo Mode in Earth Board Game

• Solo mode follows most standard game rules but pits the player against an AI named Gaia.

Setup

1. Player Board:
   • Use the solo side and choose a difficulty level: Beginner, Medium (upper action spaces), Hard, Expert (lower action spaces).
2. Gaia’s Board:
   • Place Gaia’s board next to your player board with Leaf tokens.
   • Shuffle Gaia’s deck of 6 cards and place it facedown.
   • Set up spaces for Gaia’s active card, Compost, and faceup scoring cards.

Player’s Turn

• Actions are the same as in the normal game. Always finish your action and card abilities first, then resolve Gaia’s action as the “other player,” taking the variable benefits.
• Gaia gains benefits according to the difficulty level:
  • Blue Action: Gaia gathers Sprouts (1VP per Sprout).
  • Yellow Action: Gaia stacks Growth, scoring 1VP per Trunk or Canopy completion VP.
  • Red Action: Gaia composts cards (1VP per card).
  • Green Action: Gaia places cards in her scoring pile (scores base VP at endgame).

Gaia’s Turn

• Draw and Reveal:
  • Draw the top card from Gaia’s facedown stack and place it faceup.
  • Player takes the upper ability (if any) first, then Gaia takes the lower ability.
• Yellow Action:
  • Player’s yellow abilities determine Gaia’s number of Growth pieces.
  • Gaia does not count Event cards.
• Red Action:
  • Player’s red abilities determine Gaia’s number of Soil.
  • Gaia gathers Soil until she reaches 10, then converts to Compost (10 Soil = 5 Compost).

• Revealing Gaia’s Brown Fauna Objective Cards:
  • Follow directions on the card.
  • Place Gaia’s Leaf token on the highest available VP tier next to a Fauna card.
  • Apply additional effects if playing Beginner or Expert mode.

Alternating Turns

• Play alternates until Gaia activates her last card.
• Shuffle Gaia’s deck and reset for a second use.

Endgame

• Game ends when Gaia’s deck is exhausted a second time or the player completes a 4×4 tableau.
• The player ending the game claims a 7VP bonus on the Fauna board.
• Scores are then tallied.

Scoring

• Player scores VP as in the standard game.
• Gaia scores points as follows:
  • Base VP from faceup scoring pile (negative values are positive for Gaia).
  • 1VP per Sprout.
  • 1VP per Trunk or Canopy completion VP.
  • 1VP per Compost card.
  • VP from Leaf tokens on the Fauna board.
• Gaia does not score points from Terrain or Ecosystem cards.

Team Mode (2 vs 2)

• General Rules:
  • Follows the same rules as the regular game, but players work in teams.
  • Set up the game as usual, with teammates sitting beside each other.
• Resource Sharing:
  • Players can place earned resources (cards, Compost, Soil, Sprouts, Growth) on their side of the shared Team board.
  • These resources must be taken by either teammate before the end of the current turn or they are discarded.
• Team Collaboration:
  • Teammates can openly discuss strategies and resource needs.
  • Decisions on actions, resource collection, and card selection are made collaboratively.
• Turn Order:
  • Turn order follows the player number sequence (1, 2, 3, 4, 1, 2, etc.).
• End of Game
  • Teammates combine scores and team with highest VP wins.
