Wire switches to gates, gates to the bulb, and watch real logic come alive. Logic Gates teaches you how computers actually think — not with videos or flashcards, but by letting you build every circuit yourself. Each puzzle gives you a truth table and a handful of gates. Drag wires, flip switches, test every row, and light the bulb. When it clicks, it stays clicked — because you built it. LEARN ALL SEVEN GATES Start with a single AND gate and work up to multi-stage circuits that use everything: AND, OR, NOT, XOR, XNOR, NAND, and NOR. Six chapters, 34 puzzles, completely free. BUILT FOR UNDERSTANDING, NOT MEMORISING • A guided first lesson gets you wiring in under a minute • Interactive gate cards introduce each new gate hands-on • Three-tier hints when you're stuck — always free, never paywalled • Earn up to three stars per puzzle with mastery challenges: shorter chains, cleaner wiring, the right final gate A WORKBENCH, NOT A WORKSHEET • Flip switches and watch signals flow through your circuit live • Test any truth-table row instantly • Full undo and redo, with your work-in-progress saved automatically • Calm, synthesized soundscape — no jingles, no pressure, no timers COMING SOON: LOGIC IN THE REAL WORLD A free update will add an optional pack of ten applied puzzles built from real systems: burglar alarms, safety interlocks, fail-safe design, two-person rules, voting circuits, comparators, and parity checks. See the same gates you learned running the real world. FAIR BY DESIGN • No ads. No subscriptions. No consumables. • The full seven-gate curriculum is free forever • Everything in this release is free — the optional pack arrives in a future update • Everything runs on your device, fully offline — your data never leaves it MADE FOR EVERYONE • Full VoiceOver support — every wire can be placed by tapping, no dragging required • iPhone and iPad, including Split View and Stage Manager • No account, no sign-in, no tracking Whether you're a student meeting Boolean logic for the first time, a programmer who wants to know what's underneath the code, or simply someone who loves puzzles that leave you smarter — grab a wire and see for yourself why AND, OR, and NOT run everything.
