Sequoia: Expansion Pack adds a 6th player, partnership variant, and the Negative Value expansion to this dice based area majority style game.
The Negative Value expansion modifies the area scoring for some regions to negative values. In these cases, those with the least influence in the region lose points as opposed to those with the most in the region earning points.
Additionally, this expansion increases the maximum player count to 6 which can be applied to the base game, partnership variant, or the Negative Value expansion.
The partnership variant pairs players into teams such that their combined influence is measured for area majority and both partners in the most successful team are the winners.
This was packaged together along with two other expansion in 10-Minute Games: Expansions and currently not available by itself.
