Eureka Quest

Learn science by playing. Eureka Quest is a free, Duolingo-style game built around discovery and wonder. Every explorer starts in the Method Lab — observation, questions, hypotheses, fair tests, data, and honest conclusions — then roams freely through the Science District.

The worlds

Scientific Methods (the Method Lab), Biology World (the Living Gardens), Zoology Habitat (the Wild Reserve), Psychology Lab (the Mind Museum), Chemistry Lab (the Elemental Workshop), and Physics Frontier (the Frontier Station) — with an Astronomy Observatory and a Weather Station on the way.

Short, juicy 2–4 minute lessons with instant feedback. Boss battles. Hearts, streaks, levels and badges. Chat with AI recreations of great discoverers — Galileo, Newton, Curie, Mendel, Carver and more. Earn Spark Tokens ⚡ with your lab-rat guide, Discover. Works offline and installs to your home screen. No account needed. Sister project to Literature Quest and Philosophy Quest.
