The grid is made up of magnetic and nonmagnetic plates. Each magnetic plate has 2 halves: one positive (+) and one negative (-). Halves with the same polarity cannot touch each other vertically or horizontally. The numbers outside the grid indicate the number of magnetic halves with a particular polarity in each row/column.
