Ok, I know, this game is some cheap knockoff of the classic wooden puzzle game, but some of these review go a little too harsh. I downloaded ScrewPuzzle from an ad in another game because of the interactive ad (it only let me do it for 50% of the puzzle) . Ok, so usually, when I download these apps the games are really easy, and they don’t even get harder after a long time. This game starts out actually pretty challenging, and I feel like that’s why people dislike it that much. I like it because of the challenge. Some bad things in it are the fact the ads are up to a minute long, and the timer (yes, you have to finish the puzzle in 3 minutes) and even while watching an ad, the timer STILL TICS DOWN. You have 10 lives before you have to wait for more. TLDR: App starts out difficult, many lives, but ads are way to long.
