IntroductionFengros (from Scottish Gaelic: fèin-sgrios, meaning "self-annihilation") is a drawless game for two players: Black and White. It is played on the hexagons (cells) of an initially empty hexagonal board. The recommended size is 4 cells per side, but boards of 3 and 5 cells per side are also valid. Each player has access to a sufficient supply of stones of their own color.
Definitions:
A group is the maximal set of stones of the same color connected to each other. A single stone is also a group.
The size of a group is the number of stones it contains.
Turns:Black plays first, and then turns alternate. On your turn, place all friendly stones captured by your opponent in the immediately preceding turn onto any empty cells, followed by an additional friendly stone. If your opponent captured none, only place your additional stone. Then, remove all enemy groups adjacent to any largest friendly group.
End of the game:The game ends when only stones of one color remain on the board. If you do not own those stones, you are the winner.
To balance the game, before starting, the first player places one black stone on any empty cell, and the second player chooses a side. This balancing method is called the pie rule.
