Useless game.even if you are smart enough to arrange the blocks, they will throw those blocks that are not going to fit in your sequence. And suddenly the blocks stop. There is no counting of how many blocks are gonna come so you don't know when the game will stop. Absolutely no control over the blocks so it doesn't matter whether the person playing is smart or not. Also there is no progession through levels so you don't know whether the levels are easy or hard, there is no score to beat .
