How to Play

Goal

Score the most points by building large connected groups (islands) of your color on a shared board. When all markers have been placed, the player with the highest total score wins.

Setup

Each player is assigned a unique color. At the start you receive 3 random markers — they can be any color, not necessarily yours. The board starts with a single open cell in the center.

Your turn

On each turn you must do one of the following:

A. Place a marker — place any marker from your hand onto an open cell. Every closed cell directly adjacent opens up. You then draw a new marker.

B. Swap hands — exchange your entire hand with another player's hand. Use this to grab markers of your own color.

Scoring

Your score is the sum of points from all your islands. 1 cell = 0 pts, 2 cells = 1 pt, 3 cells = 4 pts, 4 cells = 7 pts, 5 cells = 9 pts. Formula for 4+: 7 + (size − 4) × 2.
