-The game will randomly-select a 5-letter word and you have unlimited guesses to get the word right. Each time you guess, if you have a letter that matches the same location as it is in the secret word, it will be revealed to you. However, any letter that does *not* match the secret word's letter at the same location will be displayed as `_`. Good luck!
