wrd.it is what I think the worlds hardest word guessing game.
For sure! The hint (of animals) Not purebred; of an inferior strain, relates to the word underbred, trust me that's one of the easiest.
The project calls a random word API, the returned word is then put into a dictionary API. The definition of the word is used for the hint, and then you have to guess the word.
Of course, feel free to change, analyze, improve, and whatever else you might want to do!
