【A Chemistry Game for Junior and Senior High School Students!】 “Chemical Memory Match” is a brand-new brain-training × learning app that lets you enjoy and study the basics of chemistry by matching element symbols with their corresponding names. Learn fundamental topics like the periodic table and chemical formulas—covered in junior high and high school—through a fun and intuitive gameplay experience. Even if you struggle with chemistry, this app’s “learn through play” design helps you naturally absorb knowledge. It’s ideal for preparing for exams like the Common Test or former Center Test, and also works as a flashcard-style memorization tool. Perfect for science lovers or students looking to strengthen their foundation, this free app can be enjoyed by junior high schoolers, high schoolers, and even adults. The basic gameplay is simple: just like a classic memory match game, flip over cards and match element symbols (like H, O, Na) with their correct element names (Hydrogen, Oxygen, Sodium). All cards are already face-up, so the challenge lies purely in your knowledge—not memory. This format tests not only what you’ve memorized but also your thinking skills. A built-in periodic table helps you connect learning with practice in real time. Choose from three difficulty levels based on your familiarity with chemistry: (1) General Course: Element symbols 1–20 (H to Ca). Covers basic elements learned in junior high to early high school. Ideal for beginners, with an easy learning curve. (2) Science Course: Element symbols 21–54 (Sc to Xe). Intermediate level suited for high school chemistry and Common Test prep. For those who truly enjoy chemistry. (3) Expert Course: Element symbols 55–118 (Cs to Og). Advanced mode for aspiring scientists and college-bound students. Master the periodic table—never lose a science trivia battle again. Your clear time is recorded for each game, making it a time-attack challenge where you compete against your past self. Improve both your speed and knowledge with each session. Perfect for quick study breaks or light review in your spare time. You can access the periodic table anytime with a dedicated button. Even if you forget an element, you can quickly look it up—no stress. Its visual layout helps reinforce the structure and groups, making it easier to understand and memorize over time. This app isn’t just a game—it’s designed for real academic support: junior high school science review, high school chemistry preview, organizing element symbols used in chemical reactions, and early preparation for national exams like the Common Test. Especially effective for STEM-track high schoolers and test-focused junior high students. Recommended for: junior and senior high schoolers struggling with chemistry, students who find the periodic table hard to memorize, anyone who wants to learn through fun games, puzzle and brain training lovers, commuters looking to study during downtime, students who want to relax and learn at the same time, and anyone searching for a free and useful educational app. Boost your chemistry skills with just one smartphone! Begin your journey to becoming a Periodic Table Master with Chemical Memory Match — Available for free download now!
