No, 'couse I would like to maintain my "100" ...

Naturally I'm joking, the rules are quite easy, the hardest is, for me, to explain them in English, but I will try:

you have to "switch off" (black) or "switch on" (orange) a lamp considering that:
- the number in a lamp indicates how many "switched on lamps" surround the lamp (excluding the lamp itself);
- for the lamps switched on the information is always true;
- for the lights switched off the information is always false;
- there is, at least, one switched on lamp.

Here you can find a solved sample, it's in Italian but I hope you can follow the images:

I hope you could understand my bad English.

Ciao,
Gabriele

Some street lights are turned and some others off .
Initially they are all gray because no one knows which are switched on and off as the aim of the game is just locate the lights turned ON and off.
The number indicates how many lights are ON around the lamp itself (except himself) .
For the lamps ON the information is always true for the lights OFF is always false.
The game has a logical strategy, and always manages to find the lights to turned OFF, but it's pretty easy to get lost in thought.
It follows that at some point you should try to turn ON a lamp and see the "congruence" between them.

Example:
Immagine
r1c1 must be switched off, otherwise r2c2 should be ON but also false
Immagine
r2c4 must be switched off, otherwise r1c4 should be ON and false
Immagine
r1c3 should be off for the same logic above
Immagine
r3c1 must be switched off, otherwise one or both of r2c2 and r4c2 must be turned on and false
Immagine
rR4c1can not be turned off because it can not have 3 ON around.
Immagine
r2c1must be switched off otherwise r2c2 ON and false.
Immagine
r1c2 must be turned off, can not ever have 3 lamps ON around
Immagine
r4c3 must be turned off, or at least one of r4c2 and r3c4 should be ON
Immagine
r4c4 must be switched off otherwise r3c4 should ON
Immagine
r3c3 should be turned off otherwise at least one of r4c2 and r3c4 should be ON
Immagine
The remaining lamps are ON and we have the solution

Thanks Gabriele and Liu. After traversing through the above example, I could understand it very well. Still, no threat to you as regards getting 100 points.
