The animal kingdom (Metazoa, in Greek) is full of our distant relatives... some more distant than others. This game is about finding out how similar any 2 species of animal are to each other.

Your goal is to figure out today's Mystery Animal in as few guesses as possible. Wrong guesses will narrow down the answer by taxonomic rank (kingdom, phylum, class, order, etc.) The more your guess has in common with the answer, the more you will learn about the Mystery Animal.

For example, if the answer is “human”, your guesses might create a tree that looks like the following:


There is only one Mystery Animal per day, but you get 20 guesses to figure it out! A new game will start in 22h 0m.
