The game board consists of a hexagon of hexagons.
There are three players, red, green, and blue. Two edges
of the game board are red, two green, and two blue. The
two red edges are opposite from one another, as are the
two green, and the two blue.
Players take turns putting pieces of their
color on the
board. A piece may only be placed in an unoccupied space
that is either adjacent to one of that players' edges, or to
one of his placed pieces, or both.
If a player connects his two edges, he wins.
If a player moves in such a way that both of the other two
players will be unable to connect their two edges, he wins.
If a player moves in such a way that one other player will
be unable to win, then that other player drops out of the
game and makes no additional moves. The remaining two
players continue until one of them wins.
The order of turns is red, green, blue, red, etc..
A variation of the pie rule is used to ensure fairness.
Player 1 is initially red, and places the first piece.
Player 2 has the option of placing a green piece, or
changing his color to red and passing.
If Player 2 did not change colors, Player 3 has the option of
either playing a blue piece (after which play continues
normally), or switching colors with either of the other two
players (the swapped with player then becomes blue).
If Player 2 did change colors, player 3 may either play a
green piece (after which play continues normally, and
Player 1 moves as blue), or choose to change color to red,
and pass.
If player 2 and then player 3 changed color, there will be
one red piece on the board. Player 1 places a green piece
on the board. Player 2 chooses to either place a blue tile
(after which play continues normally), or switch color to
green and pass (after which play continues normally, with
player 1 as blue).
