Overview

Cascadia is a tile-laying and token-drafting game themed around the habitats and wildlife of the Pacific Northwest. Players draft habitat tiles and wildlife tokens to build a landscape mosaic, creating contiguous habitat corridors and arranging wildlife into scoring patterns. The game features five habitat types (mountains, forests, prairies, wetlands, rivers) and five wildlife species (bear, elk, salmon, hawk, fox), each with unique scoring conditions that change every game. After exactly 20 turns per player, the player with the most points wins.

Components

Setup

  1. Place all wildlife tokens in the cloth bag and shake well.
  2. Determine habitat tile count by player count: 2 players = 43 tiles, 3 players = 63 tiles, 4 players = 83 tiles. Randomly select tiles without looking; return extras to the box.
  3. Shuffle selected tiles and stack them face down within reach.
  4. Randomly select 1 wildlife scoring card for each of the 5 species. Place them in view. (First game: use the “A” cards.) Return unused scoring cards to the box.
  5. Randomly give each player 1 starter habitat tile, face up. Return unused starters to the box.
  6. Reveal 4 habitat tiles from the face-down stacks.
  7. Draw 4 wildlife tokens from the bag and pair each (in order) with a revealed tile, forming 4 tile+token combinations.
  8. Place nature tokens within reach.
  9. First player: whoever most recently saw one of the wildlife species in real life.

Turn Structure

Starting with the first player, turns proceed clockwise. Each turn:

1. Check for Overpopulation:

2. Optionally Spend Nature Tokens: Before selecting, the active player may spend nature tokens (no limit per turn) to either:

3. Select a Tile + Token Combination: Without spending a nature token, you must take one of the 4 existing paired combinations. With a nature token, you can mix and match.

4. Place the Tile:

5. Place the Wildlife Token:

6. Refill: Replace the taken tile (from face-down stacks) and token (from bag) in the center display.

Actions

On each turn you perform exactly one selection and placement as described above. The key strategic decision is which tile+token combination to take, and where to place each in your growing environment.

Scoring / Victory Conditions

The game ends when there are no face-down tiles left to replace a selected tile (each player plays exactly 20 turns).

Scoring categories:

  1. Wildlife Scoring Cards: Score each wildlife species according to its scoring card. Conditions vary by card (groups, runs, adjacencies, lines of sight, etc.).

  2. Habitat Tile Corridors: For each of the 5 habitat types, score 1 point per tile in your largest contiguous corridor of that habitat type. Tiles connect through matching edges.

  3. Habitat Corridor Majorities:
    • 2 players: 2-point bonus for having the largest corridor in each habitat. If tied, 1 point each. No bonus for second.
    • 3-4 players: 3-point bonus for largest corridor per habitat, 1 point for second largest. Ties: 2 points each if tied for largest (no second-place bonus); 1 point each if 3+ tied for largest; 0 for tied second.
  4. Nature Tokens: 1 point per unused nature token.

Total all points. Most points wins. Tiebreaker: most nature tokens. Further tie: shared victory.
