Ruzzle is a very popular game that you can play against your friends. This game is for Android and iOS. You get a plate of four by four letters to see, then you have to make as many words from these letters by connecting them with each other in any direction within two minutes. After three rounds, the game is finished and the one who collected the most points is the winner. By playing more often it is getting easier to find the words and you will also be able to make longer and longer words. The free version of this app has the disadvantage that you have to wait for five seconds after each round before you can proceed, but this is not very disturbing. Until recently, this game was called Rumble, but the name is now so changed Ruzzle.
