In this game activity, the player (student) has to guess a "mystery sentence", word by word. Each word entered by the student is compared letter by letter with the word to be guessed, starting from the beginning of the word. If a guessed letter matches the original letter, upon checking the answer, that letter is underlined with the equal sign (=). If the original letter's rank in the alphabet is situated before the letter typed by the student, the student's letter is marked with the < sign (look before). And in the opposite case, the student's letter is marked with the > (look after) sign.
