Lifle - Daily Nature Quiz

Lifle is a daily biology guessing game in the spirit of Wordle.

Every day, a new organism is waiting. Tap a kingdom – Animals, Plants, Fungi, Protists, Bacteria – and narrow down through phylum, class, order, family, genus, and species. Five guesses to identify it.

Each wrong guess earns you a clue: a fact about the path you took versus the actual lineage. Used carefully, those hints take you all the way to species.

When you're done, share a spoiler-free grid with friends and start a streak. The next puzzle drops in 24 hours.

Why Lifle? • A two-minute daily ritual that compounds into real biology knowledge • No accounts, no ads, no microtransactions • Photos and taxonomy sourced from iNaturalist's open community data • Difficulty scales from "everyone knows this one" to "even biology majors blink" • Daily reminder built in – tap once, pick your time, never miss a puzzle

Things you'll learn: • How a mushroom is more closely related to you than to a fern • Why scallops have eyes • The actual difference between a butterfly and a moth • That nautiluses outlived the dinosaurs

If you've fallen for Wordle, Connections, or NYT Mini, and you've ever paused on a hike to ask "what is that?" — Lifle is your next daily.

A puzzle a day for the rest of your life.
