VoltTrial is an electronics simulation game where you place real components, wire their pins, run the circuit and watch what happens. A built-in circuit engine calculates voltage, current and temperature, so every bulb, motor and buzzer reacts the way real electronics would.

Three ways to play. Choose who is playing. 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 a canvas, or flip a physical board, route wires on the underside and solder every joint before the 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.

Always something new. A puzzle of the day, solver-verified random challenges and a free lab with every modeled part: resistors, capacitors, transistors, motors and logic and timer chips.

VoltTrial models safe, low-voltage DC circuits for learning. VoltTrial runs in your browser, with nothing to install. It is an educational simulation, not an engineering design tool or a guide to mains wiring.
