The Grid is a formal system for philosophical disputation. It has been handed down through countless generations by the ones who live and die in pursuit of enlightenment. Its borders, once engraved with axiomatic symbols, are now worn smooth by the motion of a thousand cuffs. The Laws of Inference determine the position and motion of the stones. Shifting constellations trace the arguments of Scholars as they fight to establish the irrefutable truth of propositions whose meanings have long since been forgotten.
Object
To form an unbroken string of stones, running from any one side of the grid to the opposite side.
How to Play
You are attempting to manipulate stones (representing logical statements) on a grid (representing a formal philosophical system). Each turn you must place a stone of your color onto the grid. If you cannot place a stone you must move one stone of either color.
Winning position White has an unbroken string running form one side of the board to the opposite side.
Placing
Stones can be placed onto any unoccupied intersection of the grid, including those around the edges of the grid. The only limitation on stone placement is the Rule of Negation.
The Rule of Negation
You may not place a stone on the corner point of any square that contains one or more checkers.
Rule of Negation No stones can be placed on intersections shown marked with an X.
Movement
If during your turn you cannot place a stone, you must move one stone of either color from one intersection of the grid to another. In order to move, a stone must be situated next to an open intersection. You may move a stone in the direction of any open intersection as far as you want, until it is blocked by another stone. The Rule of Negation has no effect on stone movement.
Moving a Stone
The Rule of Circularity
You may not move a stone if that stone was the last stone moved.
Forfeit
If during your turn you cannot place or move a stone, your opponent wins.
