Your objective in Word Unknown is to guess a randomly generated word in as few moves as possible using both lexical and deductive logic. Once a legal guess is made, you'll get X's and O's in response. Each X represents a correct letter in the correct position, and each O represents a correct letter in the wrong position. There are five different difficulties (word lengths) to choose from and a daily challenge for each so you can compete with friends! Best of all, the game is 100% free and open source!
