Engirdle társasjáték

Angol leírás

Engirdle is a drawless loop-annihilation game for two players: Black and White. It is played on the hexes (cells) of an initially empty hexagonal board. The recommended board size is 7 cells per side, but boards from 5 to 9 are also valid. Each player has access to a sufficient supply of stones of their own color.

Definitions:
An internal cell is a cell from which, in each of the hexagonal directions, every infinite straight line that starts from it leaves the board after crossing at least one stone before reaching the edge; otherwise, it is an external cell.

A region is a maximal set of connected empty cells.
An internal region is a region in which all its cells are internal cells; otherwise, it is an external region.

A wall of an internal region is a maximal set of stones connected to each other where each stone in the set is adjacent to that internal region; a stone may belong to more than one wall if it is adjacent to more than one internal region.
A loop is a single-color wall that surrounds an internal region that is not adjacent to any external region.
To flip is to replace stones of one color with stones of the opposite color.

Turns:Black plays first, and then turns alternate. On your turn, perform the following actions in order:

Place a stone of your color on an empty external cell.

Remove from the board, simultaneously, all stones that are on internal cells.

Flip the stones of a wall when an internal region is adjacent only to that wall: each stone takes the dominant color of the longest wall to which it belongs; in case of a numerical tie, it takes the resulting color of the last stone placed or flipped in that wall.

End of the game:A player wins if, at the start of their turn, there is at least one loop of their color with no enemy stones on the board.

To balance the game, before starting, the first player places a black stone on an empty cell and the second player chooses a side. This balancing method is called the pie rule.
