Atomas is a fascinating puzzle game, which you can learn in seconds but will entertain you for weeks. The perfect game for your spare time! Your little universe starts with hydrogen atoms only but with the help of the energy rich plus atoms you are able to fusion two hydrogen atoms into one helium atom, 2 helium atoms into one lithium atom and so on. Your primary goal is to create the valuable elements like Gold, Platinum and Silver. But watch out, if your universe is overfilled with too many atoms it will cause a big crunch and the game is over. One way to prevent this is to build up long symmetries in your atoms and start big chain reactions. From time to time minus atoms appear, use them for absorbing and replacing atoms within your universe or sacrifice them for a plus atom. You see Atomas is not hard to play, but if you want to get to the top you'll need a good strategy, which keeps your atoms organized. By creating new elements like oxygen or copper you unlock lucky charms, which effect the game in various ways and adjust it to your strategy. What Atomas offers you: - 4 different game modes - simple but addicting game mechanics - 124 different atoms to create - 12 different lucky charms - exciting challenges - compare your scores with friends via GameCenter - share your score on twitter and Facebook - quick tutorial The developers high score is 66 534. Can you do better?

Circuit simulator game is a virtual simulation game that allows you to create, design, and test electronic circuits without the need for physical components. You may be given specific objectives or constraints that customers must meet with their circuit designs. Fun and interactive circuit builder with real animated component models. How To Play: - In this simulation game, the customer arrives at your electronics store and needs a specific circuit designed for his project. - You want to make sure that you can provide them with the best possible circuit design to meet their needs. - Start by selecting the appropriate components from a virtual toolbox, including resistors, capacitors, and transistors. - Then, you can drag and drop these components onto a virtual breadboard or circuit board, and connect them using virtual wires. - As you design the circuit, the simulator will provide real-time feedback on voltage, current, and resistance. This will allow you to test the circuit and make adjustments as needed until you get it just right. During simulation, you can check voltages, currents, and many other variables. Check signals on multichannel oscilioscope and tune your circuit in real time! Features: - One-finger control, simple and easy gameplay. - A variety of tools, components, and devices that players can use to build their circuits, including resistors, capacitors, transistors, and more. - A virtual workspace where players can drag and drop components and connect them using virtual wires. - Fun and engaging way to learn about circuit design while also improving problem-solving and critical thinking skills. - Different modes of play, such as free play, challenges, and missions, allow players to experiment with different circuit configurations and learn at their own pace. - Circuit analysis tools such as oscilloscopes, voltmeters, and ammeters to help players analyze and troubleshoot their circuits. Overall, a circuit simulator game can be a valuable tool for electronics enthusiasts and professionals alike. It allows you to quickly and easily design and test circuits without needing to physically build them, making it a great solution for situations where time, resources, or component availability may be limited.

Verdict
The clearest difference is review sentiment: Atomas at 94% against Circuit Design 3D Simulator's 42%. Atomas also leads on rating (4.8 vs 3.9) and ads (none vs shown). On price, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Atomas sells 5 one-off in-app purchases and Circuit Design 3D Simulator sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Atomas holds the better App Store score, 4.8 against 3.9. That said, the two scores are not equally well evidenced: Atomas has 3.4K ratings behind it against 202, so its average is the more settled of the two. Written reviews point the same way: 94% of Atomas's written reviews are positive against 42% of Circuit Design 3D Simulator's.
Atomas ships an update monthly, Circuit Design 3D Simulator every 4 months. The most recent releases landed on October 20, 2026 and October 18, 2026 respectively.
