## What is Nuclear?

*** Brought to you by the team behind the internationally acclaimed educational star gazing app - Star Chart *** 

Dare you enter the quantum world of Nuclear? Where things are not just stranger than you might imagine, but stranger than you can imagine! Witness the interplay of energies and physics at the tiniest of scales as you learn to play, discover and explore the chemical elements at the atomic level.

Nuclear is a high tech educational application that dynamically models an interactive atom in a beautiful and intuitive way. In Nuclear, you get to build all the elements of the periodic table via a simple mechanic of adding and subtracting the atomic building blocks of neutrons, protons and electrons. The goal of the app is to let you learn about each of the elements of the periodic table by constructing a stable version of that element. Once a stable element has been created, it is unlocked in the periodic table. Can you create and unlock them all?

This app has been designed for all types of users: from children interested in learning through play about what matter is made of and how it works, to teachers looking for an intuitive and exciting way to help educate others on chemical elements. 

Nuclear lets you: 
* Learn about the atom through this stunning 3D visualisation. 
* Explore the effects of manipulating matter at the atomic level. 
* Add or subtract protons, electrons or neutrons to create virtually any base chemical element. 
* Create and watch as unstable isotopes decay into more stable elements. 
* Through tactile exploration grasp an understanding of what we and everything around us is made of. 

- Please note the initial app allows you to create and unlock the first 54 elements for free. The remaining elements can be unlocked via a small in-app purchase.

Nuclear is continually being developed, so please feel free to let us know your thoughts and feedback. We will endeavour to expand and improve Nuclear, incorporating customer feedback wherever possible. Contact us at: Nuclear@EscapistGames.com

### 5/5 — Great but gimmick or glitch a little, close and reopen and not save progress

*2026-04-17*

Great app but something sort gimmick or glitch while you use. Trying to press ok and have to close and reopen and unlock next atom and have to do it more than once doesn’t save. Also maybe different app or time but if I can add more than 1 atom or more reaction too will be great. Only use free so far am purchase $7 one because I love it

Can we have add atoms same as bottom to see what molecules make and reactions. All available are too designed structure we need throw together like this one !

### 1/5 — The purchase to complete it

*2026-02-15, version 4.2*

It doesn’t work

### 5/5 — What an awesome app

*2025-09-24*

So helpful for seeing how atoms are created, made to be unstable, and decay into other atoms. A great representation, and even a little fun to play with.

### 3/5 — Pls read this

*2025-08-03*

I couldn’t unlock everything because I had to pay so at least you could’ve make that i can unlock everything with ads

### 1/5 — why!!!!!

*2025-01-04, version 4.2*

I used to like this game but now 🤬🤬🤬😡😠😠👎🏼👎🏼👎🏼👎🏼👎🏼👎🏼👎🏼👎🏼👎🏼👎🏼

### 4/5 — Okay,but some problems

*2024-07-08, version 4.2*

Some of the elements have wrong element symbols and it may cause confusion.

### 4/5 — Awsome, but theres a glitch

*2024-03-08, version 4.2*

I unlocked the full version and its fun! However, it’s impossible to reach 118 without buying the other thing. There is a proton cap, and it doesnt allow you to get to 118. I paid for the full 118, but i cant unlock 118 PLEASE FIX THIS

### 1/5 — Absolutely terrible

*2024-02-06*

I tried adding more protons, but it did not let me I had to upgrade it for $7.99

### 3/5 — Can’t exit out of the Element that you just discovered.

*2024-02-01, version 4.2*

What’s the title says😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡

### 4/5 — A bug?

*2023-09-06*

So when reading the description,  it doesn’t let me scroll down to read the full information,   And when trying to exit the info using “Ok”. It doesn’t work?    I hope to see a fix, yet I don’t even know if you support the game anymore since it’s been years since the last update?
