Status: TOP SECRET! INSTRUCTIONS: 1. Activate the particle generator and create Hydrogen atoms, the atoms will begin to produce energy. 2. Combine two Hydrogen atoms and get a Helium atom, this will give you much more energy. 3. Merge identical atoms and move forward along the table of chemical elements, extracting more and more energy. You can get a lot of useful information by double tapping on atoms. 4. Accumulate energy and use it to improve the laboratory and access new technologies. 5. Complete tasks and increase your scientific status, this will open access to experiments with antimatter and neutrinos. 6. Develop your laboratory and gain access to working with a nuclear reactor and hadron collider. 7. Form and train your own team of brilliant scientists to develop technology. What is inside?

Your game is your development plan, your decisions, you are in charge here! Merge – there will be many, many mergers. Combine two Hydrogen atoms and get Helium, two Helium will give Lithium, and so on until the very last element discovered by science - Oganesson. Each combination means an increase in energy production. Merge manually or use automatic merging. And if you double tap on an atom, you will get real interesting facts about it! About each of them!!! Clicker – speed up the process of generating atoms using clicks. As a gift for such activity, you will have access to experiments with the production of antimatter, and this is a very useful resource!!!
