A closer look at Metazooa
What Metazooa is
Metazooa is a daily biology game that asks you to find a mystery animal by navigating the phylogenetic tree. It frames the animal kingdom (Metazoa) as an extended family and tests how well you know relationships among animals.
How the game actually works
Each day there is one Mystery Animal to guess. You make up to 20 guesses; wrong guesses don’t eliminate things arbitrarily but instead narrow the answer by taxonomic rank (kingdom, phylum, class, order, etc.). The closer your guess is to the target, the more you learn about where it sits on the tree.
After you guess, the game shows how much of the taxonomy your guess shares with the answer so you can refine later guesses.
Who will enjoy playing Metazooa
People who like taxonomy, phylogenetic trees, or biology trivia will find this engaging. It’s suited to players who enjoy logical deduction spread across biological ranks rather than simple elimination.
If you like daily puzzle formats and tracking a single mystery animal each day, this follows that structure with one animal per day and a countdown to the next game.
