: 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!

: 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.)
