Rules
1.
The player using the black pieces is
attempting to form a Y (a continuous path joining sides 1, 3, 5 or sides
2,4,6). The player using the white
pieces is attempting to form a line (a continuous path joining opposite sides
1,4 or 2,5 or 3,6). The corner is
considered part of both adjacent sides.

2.
To eliminate the possibility of a tie, if
the black player forms a line without also forming a Y in the same turn,
or if the white player forms a Y without also forming a line in the same
turn, he loses. I.e., you cannot
achieve your opponent s victory condition unless you simultaneously achieve
your own.
3.
Because the conditions for winning are
different for the white and black player (the white player has a much easier
time joining two sides instead of three), at the beginning of the game it is
not decided which player plays with which color. Instead a variation of the pie rule (you cut, I choose) is
used. During the first part of the game
the players are in the contract phase.
During this phase both players place black pieces. At any point instead of placing a piece,
either player may pass his turn by issuing the move black . At that point it is his opponent s turn with
the white pieces (and this ends the contract phase).
4.
During the contract phase neither player
may place a piece on the edge of the board.
This is because some moves on the edge can actually be
disadvantageous. It also eliminates the
possibility of the victory conditions being met before the contract phase has
ended.
