About Periodic Panic

Periodic Panic is a fast-paced element quiz built around the real periodic table — all 118 elements, from everyday Hydrogen and Gold to deep cuts like Dysprosium and Oganesson. A symbol slots in with an atomic glow, four names appear, and the 90-second clock is running: answer fast, build a streak, and watch your multiplier climb to ×5 while the questions ramp from everyday elements into serious chemistry-class territory. Every 5-streak adds bonus seconds, and wrong answers fizzle your combo but always reveal the right answer, so every run teaches you something. Four modes keep it fresh: Symbol Rush (symbol to name), Reverse (name to symbol), the brutal Number Hunt (atomic number only), and a tap-to-learn Study Grid — a full color-coded periodic table where every element shows its name, number, group and a real-world use, from neon signs to smoke detectors. Best scores are saved per mode, and a mastery tracker records every element you have answered correctly three times, split across Everyday, School-chem and Deep-cut tiers, so there is always a next element to conquer. Periodic Panic is a FreeGamesOnline original — completely free to play, with no downloads and no sign-up. Teachers and science clubs are welcome to embed it on class pages, learning platforms and school blogs using the built-in embed code: it works great as a five-minute chemistry warm-up or a friendly classroom high-score battle on any device.

How to Play Periodic Panic

Pick a mode, then answer each question before the 90-second timer runs out. Tap an answer or press 1–4 on a keyboard. In Symbol Rush a symbol like Fe appears and you pick the element name; in Reverse you see the name and pick the symbol; in Number Hunt you get only the atomic number. Correct answers build a streak that raises your score multiplier (×2 at a 5-streak, up to ×5) and adds +3 seconds every 5 in a row. A wrong answer resets your streak but highlights the correct answer. In the Study Grid, tap any element on the periodic table to see its name, atomic number, group and a real-world use.
