Yoin is a drawless game for two players: Black and White. It is played on the spaces (cells) of an initially empty hexagonal grid of hexagons (board). Each player must have access to a sufficient number of stones of their own color. Definitions A group is a stone along with all other stones one could reach from it through a series of steps between adjacent stones of its color. The size of a group is the number of stones in it. Play Black plays first, then turns alternate. On your turn, place a stone of your color on an empty cell. When the board is full, the winner is determined as follows: 1️⃣ Let n equal 0. 2️⃣ The player with fewer groups bigger than n stones wins. 3️⃣ If no winner is found, increase n by 1 and go back to 2️⃣. The pie rule is used in order to make the game fair. This means White will have the option, on their first turn only, to swap sides with their opponent instead of making a regular move. —description from the designer
