About

Pick a dictionary and try to find the word. First letter is fixed so every board is a new challenge. Content rating The application takes into account full dictionary data and doesn't apply any word censorship. As words can be offensive and muttum developpers don't have resource to filter third-party dictionaries, muttum advertises its content as violent. The end-of-game screen also includes a link to an online dictionary giving the full definition of the word, and potentially explicit images.
