Breadboard: Circuit Puzzles

Every circuit is really simulated. Light LEDs, spin motors, tame inductors — or watch parts burn when you get it wrong. 130 levels of honest electronics.

Every circuit in Breadboard is really simulated.

Not "connect the dots" simulated — really simulated. Under every puzzle runs a genuine DC circuit solver: currents are computed, voltages divide, power heats resistors. Skip the resistor and your LED actually burns out. Short the battery and you'll cook something. If it lights in Breadboard, it would light on a real bench. That honesty is the whole game.

BUILD, DON'T GUESS You get a breadboard, a battery, and a tray of parts. Tap to place components, wire up the strips and rails, and bring the circuit to life. The board behaves like the real thing — power rails, terminal strips, the center gap. What you learn here works on a real breadboard, because it IS a real breadboard.

A REAL CURRICULUM, DISGUISED AS A GAME 130 hand-built levels across 13 chapters walk the classic hobbyist path: • LEDs and current limiting — why that resistor matters • Resistor craft — series, parallel, power ratings • Switches, motors, and buzzers — loads that need MORE current, not less • Voltage dividers and sensor chips — engineering a voltage, not just a current • Diodes and zeners — one-way streets and reference voltages • Capacitors — blocking, inrush, and hold-up • Relays — circuits that control other circuits • Inductors — including the flyback diode lesson every maker learns the hard way • Transistors — how a tiny current commands a big one • MOSFETs and level shifters — 3.3V and 5V living together • 7-segment displays — light exactly the right segments • Master Bench capstones — everything at once, under a fuse's current budget

Every mechanic is a real concept you'll absorb without ever reading a lecture.

STUCK? WATCH THE TUTOR BUILD IT The optional "Solve it for me" tutor places the solution one part at a time and explains each step with real numbers — like a patient friend at the bench. It's there when you want it and invisible when you don't.

CALM, PREMIUM, YOURS • No accounts, no cloud, no timers, no energy bars • No ads, no tracking — the app collects zero data • Fully offline — the whole game works in airplane mode • Buy once, own it. No subscriptions, no in-app purchases • A warm, tactile workshop aesthetic — parchment, brass, and glowing filaments

Made for curious tinkerers, makers, students, and anyone who ever wondered why the LED needs that resistor. Come find out — and burn a few on the way.
