About this game

Do you Know the Formula of Ozone? Or Nitrogen Dioxide? What is the Structure of Sucrose? Learn more than 300 chemical substances that are studied in introductory and advanced chemistry classes.
There are four large levels:
1. Inorganic Chemistry: compounds of metals (such as calcium carbide CaC2) and non-metals (carbon monoxide CO); inorganic acids (for example, sulphuric acid H2SO4), salts (including common salt - sodium chloride NaCl), and polyatomic ions.
2. Organic Chemistry: Hydrocarbons (from methane to cyclohexane) and carboxylic acids (from formic to tartaric acid). Natural products, including 20 common amino acids and nucleic bases that are part of RNA and DNA molecules. You can also study the most important functional groups and classes of organic compounds.
3. All 118 chemical elements and the periodic table: the questions are divided into Periods 1–7.
4. Mixed compounds:
* systematic and trivial names;
* structures and formulas;
* organic, inorganic, and organometallic compounds;
* from acids and salts to hydrocarbons and amines;
* two levels: 100 easy and 100 difficult chemicals.

Choose the game mode:
1) Spelling quizzes (easy and hard) - guess the word letter by letter.
2) Multiple-choice questions (with 4 or 6 answer options). It’s important to remember that you have only 3 lives.
3) Time game (give as many answers as you can in 1 minute) - you should give more than 25 correct answers to get a star.
Two learning tools:
* Flashcards where you can browse all compounds and their formulas without guessing.
* Table of all substances in the app.

The app is translated into 12 languages, including English, French, Japanese, and many others. So you can learn the names of the chemical compounds in foreign languages.
Advertisements can be removed by an in-app purchase.

It is a perfect app for every student preparing for chemistry classes, exams, and chemistry olympiads.

Ratings and reviews

The app is awesome but it's just like a glossary or a dictionary, there's nothing else beside name and formula ,there should be some visual cues like photos and images of the chemical substances,the reactions to how to prepare them if possible the experiments like titration and so on,however I like the concept of reviewing the formula by the test procedure but the quiz is very simple anyone can guess it.

This is a very helping app I can say thank you so much, however I feel like it does not have to focus only on substances and formulas' you need to also include more molecule structures but other than that it does help. And add maybe lessons that are related to the quiz. Once again thank you so much it is an enjoyable game.

Nice application for high school students. It has a lot of options for mastering skills in Inorganic and Organic Chemistry. Personally, I am using a basic version to prepare for the Chemistry Praxis II teacher test. The frequency of advertising display is reasonable.
