VoltTrial

VoltTrial is an electric circuit puzzle game and electricity simulation game for kids, teens and adults, with puzzles from easy to difficult. It brings learning about electricity into play: connect a battery, switch, lamp or motor, then test how your circuit behaves. The browser version is a demo you can try now; the full app is coming to iOS and Android. The features described here are for the full mobile app. In guided puzzles you place modeled components, connect their pins and run the circuit to see what works. Its circuit engine calculates voltage, current and temperature, so lamps, motors and buzzers respond to the circuit you built.

Electricity puzzles for different ages. Choose a mode for your child, a young learner or an adult exploring electronics. Sparky's World (8 and under) is a read-aloud picture world of cause-and-effect puzzles about making, moving, using and staying safe with electricity. Circuit Quest (9 to 17) has real circuit missions with stars, ranks and badges, plus a free lab with every part. Lab Unchained (18+) is the full circuit story and simulator, with every value adjustable and an Expert setting for calculation targets.

See it work. Press Run and watch electrons flow. Tap any pin for its voltage and current, open a live analysis of component temperatures, and learn why a circuit fails: open paths, shorts, reversed polarity, overheating or a missing solder joint.

From the canvas to the board. Wire freely on the canvas, or switch to a simulated board view, route wires on its underside and solder each joint before the virtual circuit will conduct.

History you can play. Follow the story of electronics from the Leyden jar onwards, with sourced chapters, dated pictures and the people behind each discovery.

An electric puzzle generator. A puzzle of the day and a random puzzle generator whose challenges are verified by a solver, so every one can be completed. Tune the difficulty, the parts and the board rules, from a gentle first circuit to difficult electricity puzzles for adults. There is also a free lab with every modeled part: resistors, capacitors, transistors, motors and logic and timer chips.

Frequently asked questions

Is VoltTrial a game or a simulator? Both. It is a puzzle game built on a circuit simulation: you solve puzzles by building circuits that the engine then runs.

Is it suitable for kids? Yes. Sparky's World is made for children aged 8 and under, and Circuit Quest for ages 9 to 17.

Is it for adults too? Yes. Lab Unchained is for adults, with every value adjustable and an Expert setting for calculation targets, so the electricity puzzles can be genuinely difficult.

Can I try it for free? The browser demo is free to try now. The full app is coming to iOS and Android.

Why I started VoltTrial

I first wanted to make something that would help my kids understand electricity. I wanted them to see a circuit as a connected path rather than a collection of names and symbols. If they connected a battery, a switch and a lamp, they could ask why the lamp lit, why it went dark when the path opened, and what had changed. Those are small questions, but being able to test them can make the next question less intimidating.

When I was a child, I loved wiring motors and making small toy cars. That interest in putting parts together is still with me. I want other people to see how components connect and work, too: where the current has a path, what a resistor changes, and why the same parts can behave differently when they are wired another way. Understanding a circuit begins with tracing what is connected to what, then checking whether the result matches the idea you had.

I worry that practical knowledge can become less visible as AI, robots and factories do more of the making. I can use a finished device without seeing the decisions inside it, and I do not want the connections between parts to disappear from view. I would like VoltTrial to give curious people a reason to pause at those connections, to ask what each part is doing and to follow a change through the whole circuit. That kind of understanding starts with an experiment you can inspect.

Simulation gives that experiment room to go wrong. In VoltTrial you can place modeled parts, connect them, run the circuit and check the result. If a lamp stays dark or a value surprises you, you can change one connection and run it again. The trial happens on a screen, so a wrong connection cannot damage a physical component or put you in contact with a live build. I hope that makes it easier to explore an idea and understand an outcome before trying something with real parts. Real electrical work still calls for care and supervision.

VoltTrial models safe, low-voltage DC circuits for learning. It is an educational simulation, not an engineering design tool or a guide to mains wiring.
