Your aim is to correctly place the magnets and blank dominoes such that
all the clues are satisfied, with the additional constraint that no two
-similar magnetic poles may be orgothonally adjacent (since they repel).
-Neutral poles do not repel, and can be adjacacent to any other pole.
+similar magnetic poles may be orthogonally adjacent (since they repel).
+Neutral poles do not repel, and can be adjacent to any other pole.

Right-clicking on an empty square places a blank domino there.
Right-clicking again places two question marks on the domino, signifying
-'this cannot be blank' (which can be useful to note deductions while
-solving, and right-clicking again empties the domino.
+\q{this cannot be blank} (which can be useful to note deductions while
+solving), and right-clicking again empties the domino.
You can also use the cursor keys to move a cursor around the grid.
Pressing the return key will lay a domino with a positive pole at that
\dd Size of grid in squares. There will be half \e{Width} \by \e{Height}
dominoes in the grid: if this number is odd then one square will be blank.
