Picture Logic - brain puzzle -

I enjoy this app, but there are too many ads. It will not let me skip levels. I’ve played picross before, the 5x5 squares are too easy and a bit dull. They take like a minute. Which means I’m watching an ad every minute because there is always one after I solve the puzzle. I have 15x15 unlocked on my phone which is also incredibly frustrating. The squares are too small for my fingers. It’s too easy to press the wrong one. You only get 3 mistakes, then you have to either watch more ads or restart entirely. Other sites do not tell you if you’ve made a mistake until you submit it, I like this approach better, it gives you room to guess and correct yourself along the way.
