If you found that title confusing, you must not know A Truly Fun Game. This descriptively-titled puzzle uses simple Tetris-like elements, but isn't really Tetris-like at all. Nothing is falling out of the sky, and you don't need fast reflexes -- all you need is lots of patience, and a good eye.
Your job, should you choose to accept it, is to mess around with the pieces until you manage to fit them all into the rectangular area at the center of the board. They all fit there, somehow -- and you don't have to rotate them to make them fit. This sounds simple, and in the first few levels, it really is. But once the board grows larger in later levels and you start getting more and more pieces to match, the difficulty ramps up.
There is a surprisingly large number of permutations and ways to place a bunch of blocks while trying to make them fit into a neat rectangle. Eventually, you will meet your match -- there will come a level you simply can't crack on your own. That's where money comes into the picture: You can buy hints via in-game purchase. The game is also supported using a relatively unobtrusive ad banner shown across the bottom of the screen, as well as way-more-obtrusive interstitial ads that butt in between levels and take over the whole screen.
While A Truly Fun Game ships with both a light and dark theme, both are equally unattractive. I don't have many good things to tell you about the soundtrack, either. But here's the thing: It doesn't really matter. What does matter is the huge variety of levels the game is packed with, and the compelling gameplay experience itself.
So, the graphics won't blow you away, the interstitial ads will probably annoy you, and still, you will find yourself enjoying A Truly Fun Game. Well worth it for fans of puzzle games -- there's a reason over a million people downloaded A Truly Fun Game so far.
