Date: Tue, 13 Dec 1994 23:27:31 GMT : 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.

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! ------------------------------------------------------------------------------- Bill Taylor wft@math.canterbury.ac.nz ------------------------------------------------------------------------------- I'm not one of the main actors in the computing world, just a bit player. ------------------------------------------------------------------------------- Newsgroups: rec.games.abstract From: rrognlie@netcom.com (Richard Rognlie) Subject: Re: The Game of Y: rules/info ? Date: Fri, 16 Dec 1994 12:42:06 GMT : 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 \/\/\/ | (Fax) (703) 556-1174
