Lights On
Martin J. Chlond
Each of the squares in the above grid can be in one of
two states, lit(white) or unlit(red). If the player clicks
on a square then that square and all squares in the same
row and column will toggle between the two states.
Each mouse click constitutes one move and the objective
of the puzzle is to light all 16 squares in the least
number of moves.
