Lifle - Daily Nature Quiz
Learn life, one organism a day
Free · Designed for iPad. Not verified for macOS.
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.
