Cascadia

Turns: clockwise, draft a tile-and-token pair and place them in either order. A new tile must share a full edge with your landscape; do not overlap or move existing tiles. Place the animal on any empty tile showing its matching icon.

Overpopulation: before drafting, four matching animals must all be replaced, repeatedly if necessary. With exactly three matching animals, you may replace those three once per turn. Keep removed tokens aside until overpopulation is resolved, then return them to the bag.

Nature tokens: before drafting, spend one to choose any tile and any animal independently, or to replace any number of animals. You may spend several tokens in a turn. Populating a keystone tile earns one token; each unspent token scores 1 point.

Wildlife scoring: select one card per species during setup; use the A cards for a first game. Bears need separate groups of exact sizes; elk use the specified formations or groups; salmon need unbranched runs; hawks use separation or sight lines; foxes score neighboring animals. Apply the selected cards and the clarifications on page 11.

Ending and basic scores: each player takes exactly 20 turns. Play ends when the selected tile cannot be replenished. Score the five wildlife cards, then 1 point per tile in your largest connected corridor of each habitat type; separate corridors of the same type are not added together.

Habitat bonuses: with two players, the larger corridor earns 2 points, or 1 each if tied. With three or four players, first earns 3 and second 1; two tied for first earn 2 each, three or more tied for first earn 1 each, with no second-place award. Tied seconds earn nothing. A total-score tie favors more remaining nature tokens, then shared victory.

Solo: use two-player setup. After placing your selection, discard the tile and animal furthest from the draw stacks, slide the remaining two pairs and refill two pairs. Play 20 turns. Each habitat whose largest corridor has at least seven tiles earns a 2-point bonus instead of a majority comparison.
