(A variant for playing
on 2 Quadtria boards simultaneously)
Story line
The pyramids were created by the extraterrestrials
as a link to a parallel universe. Their subterranean
spheres would travel between the universes even as they
traveled along the passages.
Equipment needed
2 complete Quadtria sets (each board represents a
gateway to a parallel universe under the pyramids.)
The Object of the Game
There are two ways to win. You may attempt either
of them at any time during the game.
1) Block both world gateways by forming a quadtria
of your color on each board.
OR
2) Position balls of your color to forever prevent
your opponent from achieving the first goal. Specifically,
move 8 of your balls to one of the boards to fill two
diagonally opposite corners in every quad on that board.
Note that your opponent will be unable to make a quadtria
in a given quad while you occupy a pair of opposite
corners there.
The first goal will be familiar to Quadtria players.
It is the same as in the regular game, except to win
you need a quadtria on both boards
at the same time. Note that during the game,
quadtrias may be formed (and released) by either player
before this condition is reached.
(For those unfamiliar with the original game, a "quadtria"
is any triangle of one player's pieces that lies within
one of the three square regions (quads) outside of his
initial quad. - Or also in the initial quad, after the
signal peg has been reversed.)
Preparation
Prepare two Quadtria boards in the normal way. Place
them side by side in the same orientation.
Choose the color you will play. You play the same color
on both boards.
Decide who will start.
Game Play
Each turn consists of moving one game ball of your
color from board to board. The move is based on the
normal Quadtria move in which a ball moves from one
point to an adjacent point which is free. The ball must
move to the other board, it may not simply move on its
own board.
Specifically, on your turn you choose a ball from
either board, then start to move it along a passage.
But before reaching a new resting point, the ball is
teleported to the other board, to the same part of the
corresponding passage. The ball continues to move in
the same direction as it began until it comes to a point.
This new point must be unoccupied; it must be the first
point the ball reaches; and the ball must stop there.
Signal peg
Like in the regular game, when one of your initial
quads has been cleared of all your balls, so that none
remain inside, you turn the signal peg over for that
quad. Each initial quad is treated independently, you
can clear one of them at a time.
Winning
Unlike in the regular game, the first quadtria does
not win. On a single board, either player might temporarily
have more than one quadtria. However, two of your quadtrias
on the same board does not win. It is not until a player
completes a quadtria on both boards at the same time,
that the first goal is fulfilled, and that players wins.
Alternatively, the game may end when a player occupies
the every quad on one of the boards with two pieces
that are on a pair opposite corners in each of their
respective quads. The player who achieves this pattern
wins.
