4-4? Look at the curly-brace numbers. If you have a curly-brace number with only so many consecutive cells around it, you can often get some in the middle for certain.

Yes, that's the idea. Here's how it works in practice:

I figured this out a long time ago, but thanks for the answer anyway :P

Thx CristyB

Hi. I've been in that situation myself... Eventually, i realized the game *does* let me know whether i've fully completed the levels, although in a VERY subtle way:

Hello guys, I just want to say that I had no problem with understanding the level.

And the reason for that it's because I had played nonograms before.

And the way that level has to be though is the basic mechanic to play nonograms.

If you like logic games, I really recommend nonograms.
