Lights Out (F) (1997) (PD) - Amstrad CPC - Puzzle, Logic.

The principle of the game is relatively simple. There is a grid of 5 by 5 squares. Each square (which are actually the lights) can be either red or white. To win you must place the squares in white. To do this, you can click successively on the boxes of your choice. But when you click on a box, it is a cross made up of four boxes and centered around the chosen box which changes state. The game tells you the minimum number of moves needed to win the current level, but it gives you 18 more. If you do not respect this condition you will not progress to the next level. The number of trials is unlimited. The game has 44 levels and you can choose your starting level. In addition, you are entitled to call for help twice in a row at the start of the game.
