Lights Out is a logic game wherein all lights need to be turned off to complete each board. See the first problem in the series for an introduction.

This problem contains boards that each require four moves to solve. For example, if

 board = [1 0 1 1 1  
          1 1 0 1 0  
          1 0 0 0 1  
          1 0 0 1 1  
          1 1 0 0 1]

the answer is:

 moves = [2 5 16 24]

Prev.: 5x5, 3 moves — Next: 5x5, 6 moves

Hello Grant, you should create a problems Group with the Lights Out serie.Good problems as always.

Or maybe add the Lights Out 1 and Lights Out 7 or 8 (for a progression in difficulty) in the Classic Games Puzzles. By the way I thing that problems in Computer Games 1 are more Maze problems (except 2048 Move). Some others Maze problems (One Track Five Lanes of Alfonso) can be added.
