Cycloop vs Logic Gates

Every loop you close adds an instrument. CYCLOOP is a calm pipe puzzle with a lofi jazz heart. Tap tiles to rotate them and connect every pipe. Each part of the board you close brings another layer into the groove (drums, then bass, then melody) until the whole song plays and the board lights up as a picture. WHAT'S INSIDE • Music you build: every closed loop adds an instrument, and every connection plays a note in time with the beat. • 30 hand-drawn pictures: a heart, a cat, headphones, an anchor… every board reveals what it was. • Five more chapters: 150 puzzles, from mirrored loops to grand mandalas, each with exactly one solution. • An endless encore once you finish the song. • Your gallery: every solved board is kept as a neon picture. • No pressure: no timers, no lives, no penalties. Play offline at your own pace. • Hints when you get stuck, and Game Center leaderboards. Rotate. Connect. Listen.

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.
