How to play Metazooa
- Guess any animal
Type an animal, like a clownfish or a platypus.

Your guess joins the tree at the group it shares with the answer, such as mammals.

How the tree of life clue works
Metazooa, from Trainwreck Labs, hides one animal a day and gives you up to 20 guesses. Every guess is placed on the tree of life, and the game tells you the deepest group your guess shares with the answer. Share only the class and you are far off. Share the family and you are very close.
| Level | Example for a lion |
|---|---|
| Phylum | Chordates, animals with a backbone or close to it |
| Class | Mammals |
| Order | Carnivores |
| Family | Cats |
| Genus | Big cats |
| Species | Lion |
A guessing plan
- Start wide. A common mammal, a bird and a fish in your first three guesses tell you which big branch to climb.
- Do not skip levels. Once you know it is a mammal, find the order before you guess species.
- Think beyond backbones. Insects, spiders, jellyfish and snails are all fair answers.
Metaflora for plants
The same team makes Metaflora, which uses the identical idea with plants. If you liked biology class, the two together make a good daily pair.
Metazooa tips
- Start broad with very different animals, like a fish, a bird and a mammal.
- Once you know the class, guess within it to find the order and family.
- The tree is about relatives, not looks. Whales are closer to hippos than to fish.
- Note the group names the game shows you. They are worth learning for the next animal.
