p.boxed
  | Each piece has a charge generating a magnetic field,
  | attracting enemy pieces while repelling others.

p.
  Every piece has a charge generating a magnetic field, except the two kings
  which have a neutral charge. Pieces of the same color have let's say a
  positive charge, while the others have a negative charge. After each move
  positive charges attract negative ones, and repel positive ones.

p.
  Win by capturing opponent's king. There is no notion of check or stalemate
  here.

p.
  Remember that since kings have a neutral charge, any of their movement does
  not change anything on the board. They also block magnetic actions which go
  in their direction.

p.
  Castling is possible, but no en-passant captures.
  While castling, the changes are made by the rook movement.
