So…
I downloaded the game, started playing it, got stuck on level 14, then level 17. I read the reviews and everyone was stuck in this game at some point. I kept trying to pass level 17 and almost gave up, but then I finally passed it and guess what? The game is easier than I thought it would be. Right now I am on level 135 on my phone and level 101 on the iPad. Yeah I got so addicted to the game that I play it on both devices, whatever. Anyway, I think after level 17 the levels started repeating, so it was easier to pass them cause it was the same thing over and over, that’s how I got to level 101 and 135. To make it easier I made screenshots of the hardest levels cause I couldn’t memorize all spots for the squares. It gets easier with time, just eliminate the spots where the blue squares 🟦 cannot go. And I think the developers of the game didn’t create a hint button because it’s actually a really simple game to play. Good luck to everyone, I’m going to continue playing the game, hopefully I’ll reach the end of it.
