I equate this style to not being allowed to have dessert until you clean up the veggies and beef on your plate. Each level has 16 different puzzles. Four images are presented on your screen. You have to figure out what the word is in each image, in order to piece together the name of the film. They don't give it away by giving you still images from the film. They got much more witty and found everyday photos to illustrate each word.
I don't recommend playing this game on your smartphone. The screen is too small for full enjoyment. A tablet will definitely give a break on your eyes, but if you can play it on Facebook, you'll get the full experience. Because I'm on my smartphone, I've had a bit of difficulty being able to adequately see the images clearly enough to figure out what each one represents, so I started going to 4 Pics 1 Movie Answers, when it became a problem. This kept the gameplay going and me interested in what they were trying to tell me.
If you are a fan of the cinema, it won't hurt to download this free app and give it a try. Your worst case scenario is that you wouldn't like it, which is a quick delete and you're on to the next game. There's not much to lose, really.
