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 call

The clearest difference is review sentiment: Circuit Design 3D Simulator at 42% against Screw Guru's 14%. Circuit Design 3D Simulator also leads on iOS requirement (12.0 vs 15.0). Screw Guru's advantage is rating (4.3 vs 3.9) and update cadence (every 3 weeks vs every 4 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Circuit Design 3D Simulator sells 3 one-off in-app purchases and Screw Guru sells 33 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Screw Guru holds the better App Store score, 4.3 against 3.9. That said, the two scores are not equally well evidenced: Screw Guru has 6.4K ratings behind it against 205, so its average is the more settled of the two. Written reviews complicate that: 42% of Circuit Design 3D Simulator's written reviews are positive against 14% of Screw Guru's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Circuit Design 3D Simulator ships an update every 4 months, Screw Guru every 3 weeks. The most recent releases landed on October 30, 2026 and November 1, 2026 respectively.
