Brood

Brood is a polyhex-matching game for two players – Black and White – played on an initially empty hexagonal board. Rules: • On the very first turn, Black places one stone on any hex. • From then on, starting with White, the players take turns placing exactly two stones each on empty hexes. • A player is allowed to pass instead of placing their two stones. • When the players pass in succession, the game is over, and the player with the higher score wins. Scoring and the definition of a brood: • The score is a function of the players' broods. • A brood is a set of groups of the same shape, size and color. • Shapes are considered identical even if they are rotated or mirrored. Example: A black group consisting of 3 stones in a line makes up a brood together with all and only black groups of 3 in a line. • The point value of a brood is the number of stones in it multiplied by the smallest of the following two numbers: (i) The number of groups in it. (ii) The size of the groups in it. Example: If Black has 4 groups that are 3 stones in a line, this brood is worth 36 points. That's the number of stones in it (12) multiplied by the size of the groups in it (3). —description from the designer
