| - | == About Magnetic Fields ==
| + | |
| - | | + | |
| - | ===Technical Information===
| + | |
| - | | + | |
| - | The magnets used in Polarity are thin solenoids. The magnetic field comes out of the centre of the magnet and bubbles around the outside to come back in the centre on the other side. It is shaped like a doughnut.
| + | |
| - | | + | |
| - | In the centre of the disc (the doughnut hole) the field is very strong and convergent. Disc centres facing each other this way will either strongly attract or strongly repel.
| + | |
| - | | + | |
| - | The field around the side of the disc is weak and divergent and won't cause too much force.
| + | |
| - | | + | |
| - | When you place a leaner you are really pointing the bottom centre of your leaner at the bottom of the foundation. These have a repulsive force. When this force balances the gravity pulling down on the leaner, it will hover as it should.
| + | |
| - | | + | |
| - | If the leaner gets too vertical, the bottom centre of the leaner is now pointing at the top of the foundation. This creates an attractive force and will probably suck the foundation up. This is why playing on towers of 2 is fairly easy, because the centre of the top magnet is higher and the leaner won't point at it. Playing on very high towers is hard because you are using mostly the divergent side field for support. They must stand almost vertical to minimise the pull of gravity.

| - | | + | |
| - | You can see why leaners add so much instability to the board. Rather than the strong part of their field pointing straight up (as foundations and towers do), leaners point their field somewhat across the board surface too. The more vertical the standing piece, the more the field points across the board.
| + | |
| - | | + | |
| - | Sometimes you can imagine a straight line (or a cone or fountain) coming out of the centre of all the discs to try and get an idea of the magnetic field topography.

| - | == Point System ==
| + | |
| - | | + | |
| - | Here is how your ''relative'' score can change on your turn:
| + | |
| - | | + | |
| - | * Cause an impossible conversion: +2 or more points.
| + | |
| - | * Lay a standing piece: +1 point.
| + | |
| - | * Convert a foundation: +0 points (but you get a new foundation).
| + | |
| - | * Convert an opponents leaner: -0 points (and your opponent gets a foundation).
| + | |
| - | * Flip your own leaner: -0 (your opponent gets this foundation where it lies).
| + | |
| - | * Flip opponents leaner: -0 (your opponent gets to put a foundation anywhere).
| + | |
| - | * Cause pieces to touch: -2 or more points (This can be better or worse depending on whose foundations were included in the tower)
| + | |
| - | | + | |
| - | (Note is does not matter if the action piece was involved in a tower, if it goes back in to your stack it means you got 0 points from it. If it goes to the tower that means that it left your stack (+1) but your opponent gets it as a point (-1). This is why the action piece must be resolved carefully after a fault and should not be left standing or laying on the board)
