: I am interested in learning more about the game : I saw this reviewed in games magazine 12/94.
The game is played on a roughly triangular board that looks something like the following:
____ / \____ / __/ \__ \__/ \__ \____ / \ \____/ \__ / / __/ \__ \____ \ \__/ \__ \____/ \__ / / \ \____/ \__ \__ \__/ / __/ \__ \____/ \__ / \ \__/ \__ \____/ \ \__

Players take turns placing stones of their colour (one player is white, the other black) on the board, trying to connect the 3 sides of the board with a single set of fully connected stones. The stones are placed on the intersection points on the lines. A corner counts as being part of both sides.

[Exellent ascii board, program-drawn by Dan Hoey; snipped]
Players take turns placing stones of their colour (one player is white,
the other black) on the board, trying to connect the 3 sides of the board
with a single set of fully connected stones.
And don't forget the variant invented by Dan Hoey & myself, "Projective Y":- played on the same board, but with diametrically opposite edge points identified, (i.e. a board on a projective plane), the winner being the first to make a closed loop which is non-contractible-to-a-point.
This is one of the more abstract of abstract games around; it should appeal to mathematicians in particular. J.H.Conway should have invented it!

: Why was the board shaped like that, rather than a straight hexagonal : lattice?
There are 3 points which have only 5 connection points (rather than the normal 6). That forces the curved shape. It also reduces the 1st player advantage a little (in theory). I still opt for 1 move equalization (e.g., player A moves. Player B has option of accepting player A's move as his own, or making his own move. Play continues.) – /\/\/\ | Richard Rognlie / Sr. Computer Analyst / PRC Inc. / McLean, VA / \ \ \ | E-Mail: rrognlie@netcom.com *or* rognlie_richard@prc.com \ / / / | Phone: (Home) (703) 361-4764 (Office) (703) 556-2458
