Breadboard vs Siliconnect

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.

Wire up the chip. Siliconnect is a wire-routing puzzle: trace between pads with the same name to connect them. Wires can't cross, so you have to decide where each one goes, and in what order. Every wire you draw changes the paths left for the others. ■ 6 chapters, from silicon to circuit board Each chapter adds a new rule based on real chip design. • Diffusion — where polysilicon crosses diffusion, a transistor gate forms • M1 — a single metal layer, so wires can't cross • M1/M2 and vias — vertical and horizontal on separate layers; change layers to turn • Power — wide power lines block the routes next to them • Package — bond wires run from the die's pads to the leads without crossing • PCB — match the lengths of differential pairs and avoid long parallel runs ■ Find the shortest route Each clear is rated S, A, or B by total wire length. Find the shortest wiring and collect S ranks. ■ Build logic gates from transistors In LAYOUT mode, wire transistors to build NOT, NAND, NOR, AND, and OR gates. Turn every row of the truth table green to finish. ■ Learn while you play Each main-game stage you clear shows a short fact about semiconductors. Each chapter opens with how its rule is used in real design. ■ What's inside • Main game: 6 chapters × 10 stages (60 stages) • Endless mode, unlocked by clearing every chapter (100 stages) • LAYOUT mode for building logic gates (5 gates) • Hints when you're stuck (one free hint per stage; more by watching an ad) • English and Japanese Some parts of real chip design are simplified so they can be played as a game. Each chapter's "In real chips" section explains the differences. Siliconnect is free and shows ads. No account is needed, and your progress is stored on your device.
