It doesn’t even work most of the time. I found a piece to complete a puzzle, put the piece in, nothing happened, clicked out of it and back in multiple times, finally used a hint, and it told me to click on it, which is what I had been doing, but it only worked after I used a hint. There were multiple other times that I was doing something right or putting the right answer in, but it would only accept it after I used the hint. To use a hint you either have to pay money or watch an ad, and there’s ads at the top and bottom of the screen and if you accidentally clicked on one you have to find the tiny “x” to close it out and then it forces you to watch another ad after you close it out. It seems like it’s only purpose is to push ads and the smallest amount of effort possible was put into the actual game.
