Description

Game-of-6 is an abstract strategy game for two players that can be played on a grid paper sheet, using pens of two different colors. (it's an evolution of classic Connect6). Rules:
1. The player that opens the game places one dot of his/her color in a cell. In all the following moves, each player places consecutevely two dots in any empty cell of the grid.
2. A player that aligns (horizontally, vertically or diagonally) six (or more) of his/her dots wins the game.
3. Each time a player completes a closed polygonal with his/her marks, all the internal cells take that color. A closed polygonal is any closed path connecting dots of the same color, each adjacent horizontally, vertically or diagonally to next one
4. The grid cells, once colored, are blocked. They cannot change their color even when they are enclosed in a new polygonal of the opposite color and do not take part to any alignment of dots. If a move generates both a closed polygonal and a winning alignment, the latter is prevailing and the game is over.
4.2. A player turn is made of two separate moves: if the first one closes a polygonal, the internal cells must be colored before the second move is performed.
4.3. A player can always enlarge an existing polygonal by adding new dots
5. A player that colors six (or more) cells wins the game. It's not necessary that the six cells are enclosed by the same polygonal: the winning number can be made adding up spatially separated colored cells.
When the game is over, the winner gains six points and the loser one point for each cell he/she was able to color.
A match is composed by six games, to be started alternately by the players. The winner of the match is the player with the most game victories, and in case of a tie, the one who scored the most points.
