Chemistry does not have to be boring, confusing or stressful. Kemistri is an interactive chemistry learning game that helps students understand important concepts, practise problem-solving and enjoy learning through guided gameplay. BUILD UNDERSTANDING, NOT JUST MEMORY Kemistri acts as a friendly learning guide, helping you build strong chemistry foundations instead of simply memorising facts and formulas. Through interactive challenges, you can: β€’ Explore the periodic table β€’ Understand atomic structure and electron arrangement β€’ Build electronic configurations step by step β€’ Apply electron-filling rules β€’ Construct molecules and chemical structures β€’ Identify different types of chemical reactions β€’ Practise balancing chemical equations β€’ Explore periodic trends β€’ Learn VSEPR theory and molecular geometry β€’ Understand hybridisation β€’ Explore acids, bases and the pH scale β€’ Solve chemistry problems logically Helpful explanations and hints guide you when needed, keeping learning rewarding rather than frustrating. INTERACTIVE CHEMISTRY ACTIVITIES Kemistri contains a growing collection of chemistry games and challenges, including: β€’ Placing elements in their correct periodic-table positions β€’ Arranging elements into the correct groups and periods β€’ Building electronic configurations for different atoms β€’ Filling atomic orbitals using electron rules β€’ Constructing molecules β€’ Recognising reaction types β€’ Balancing chemical reactions β€’ Exploring atomic radius, ionisation energy and electronegativity β€’ Learning molecular shapes and chemical bonding β€’ Experimenting with interactive chemistry tools Each activity introduces concepts through interaction, repetition and progressively more challenging levels. DAILY LEARNING AND DISCOVERY Keep learning with daily chemistry challenges, build your study streak and unlock achievements as you progress. Explore science legends, chemistry history, fascinating facts and jokes that make learning more memorable and enjoyable. MADE FOR CHEMISTRY REVISION Kemistri is suitable for: β€’ School chemistry revision β€’ Students beginning to learn chemistry β€’ GCSE, A-level and equivalent learners β€’ Daily concept practice β€’ Curious learners who enjoy science Its calm, game-based approach makes revision more enjoyable and helps students practise without the pressure of a traditional test. LEARN AT YOUR OWN PACE Whether chemistry is completely new to you or you want another way to revise familiar topics, Kemistri allows you to progress gradually. Start with the fundamentals, complete interactive challenges and build confidence as new topics are introduced. BUILT WITH PASSION Kemistri is created by a small independent team focused on making science education more engaging and accessible. Your support helps us develop new chemistry content, improve the experience and expand language access.

Atom Worldbox

Features
Read full description

The entire periodic table is yours to play with. Drop atoms onto the screen, watch them bond into real molecules, and trigger genuine chemical reactions all driven by real science, not scripted animations. Atom Worldbox is an open-ended chemistry and physics sandbox. There are no levels, no goals, and no rules just a living world of atoms governed by the same forces that shape the real universe. Bring two elements together and see whether they bond. Build a known molecule and the app recognizes it instantly. Push reactive elements together and watch reactions ignite, transform, and settle on their own. WHAT YOU CAN DO β€’ Experiment with every element on the periodic table β€’ Watch atoms form covalent, ionic, and metallic bonds based on real chemistry β€’ Build molecules and see them automatically identified β€’ Trigger authentic chemical reactions and watch them unfold naturally β€’ Turn on Thermal Mode: heat and cool your world β€” condense gases into droplets, boil them, or fuse hydrogen at star-core temperatures β€’ Explore radioactivity, isotopes, and natural decay β€’ Set off chain reactions and watch them cascade across your world β€’ Zoom, pan, and arrange everything with simple, intuitive touch controls REAL SCIENCE, NOT SPECIAL EFFECTS Every bond and reaction is calculated from real chemical and physical principles. Atoms attract and repel, electrons transfer, and molecules come together exactly the way they would in nature. It's a living simulation you can build, break, and rebuild as many times as you like. GREAT FOR β€’ Curious minds who love to experiment and explore β€’ Students discovering chemistry and physics β€’ Teachers looking for an interactive way to show bonding and reactions β€’ Anyone who loves satisfying, science-driven simulations Works fully offline. No account required, no clutterβ€”just open it and start building. Atom Worldbox is free to explore. Upgrade to Pro to unlock the complete sandbox experience.
