Highlight for switched windows added.

App Description

An app for bright and extremely determined people.

Consider a night city. Some windows are lit, some are dark. Due to a construction feature, it is not possible to switch light in a single window as the switches turn light in all its adjacent windows, too. Help the inhabitants to get light On in all their windows! Or send them all to bed...

That's not that easy, but possible. Do not give up easily! You can develop your own algorithm. At least use Magic and follow it to solve the puzzle, this is a pure relax in this case.

- Professionally recorded wonderful energetic background music;

- Great for logic and algorithmic thinking development, for entertainment;

- Highly relaxing;

- Makes you feel bright!

- Great as a gift app.
