Light Cross: free puzzle app game for ipad, iphone

Light Cross comes from http://keaton.com/apps/lightcross/en/

This type of puzzle has been done many times before under different names: Akari, Lighthouse, to name a couple.

Look at the first image. See the 2? you must place 2 lights on the adjacent sides. All cells must be illuminated. A light bulb cannot be in the path of another light bulb.

There are 40 free levels. I've done them all, very quickly. I particularly like the design of the boards: they are not necessarily squares.

I tried to purchase the 'Green Pack' of puzzle levels. But I don't think they're available yet.
