Another addictive game to steal some time form you, found via Stumble. Go waste some time Searched bit for this and couldn't find it so I'll assume it hasn't been posted before. Note: Requires brain.
Took me a couple of hours to figure em all out. Sometimes you just have to go play a game for 5 minutes and come bakc to one when you can't get it. Note added
They can all be done, just keep trying. Hint Spoiler For number eleven the splitter goes on the left of the wall in the bottom left were there are two wall blocks. Splitter WA .............LL .............WA .............LL
i'm on 13 now - i thought 11 was the hardest so far! I saw your hint after i finished 11 btw, i came back here to post that 11 isn't actually faulty (who woudda thought?)
reminds me of an old game called "laser light" http://www.abandonia.com/en/games/782 basically the same concept
I got to one lightbulb away from passing 18 last night - i think 18 may have a fault edit: it seems this website has a fault aswell! it can't be me can it?
