Logic Gates vs Gate Master

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.

The town has lost its power! The lamps are dark, the bank vault is locked, and the traffic lights have gone out. Travel from region to region with your guide Wire, fix the circuits and bring the town's lights back on. Gate Master is a puzzle game played with real logic gates. Every level shows a real device at the top of the screen: a night light, a doorbell, an elevator, a traffic light. Below it sits the circuit board. Drop the right gate into each empty slot, press Test and watch whether the device works in every case. MEET THE GATES Every gate has a face and a personality: AND with its glasses, OR with its little sprout, NOT who flips everything around, NAND in a cape, XOR with a crown... When their output is 1 their faces light up, and at 0 they doze off. Each new gate arrives with its own intro card. BUILD, PREDICT, FIND THE FAULT Levels don't always ask for the same thing: • Build: place gates in the slots, and sometimes choose where a wire goes • Predict: look at the circuit. Will the lamp turn on or stay off? • Set the switches: flip the inputs to reach the goal • Find the fault: spot the wrong gate and swap it • Only these gates: copy one gate using just one kind of gate • Machine: a big circuit at the end of every region 10 REGIONS, 200 LEVELS Home, Bank, Apartment, Greenhouse, Factory, Stairs, Workshop, School, Traffic and Clock Tower. You start with a single wire and a NOT gate. After AND, OR, NAND, NOR, XOR and XNOR come binary numbers, adders, a 7-segment display, selectors, decoders and, at the very end, memory and counters. The challenge grows step by step, and every level was checked to be solvable. TEST IT, WATCH THE LIST The Test button tries every input combination in turn, filling the list of tries row by row. You see exactly which case went wrong. In the first levels the list uses pictures, and 0 and 1 come later. LIGHT UP THE TOWN As you repair the circuits, dark devices switch on one by one and the town lights up region by region. STARS AND HINTS Every level has 3 stars: solve it, get it right on the first Test, and finish without hints. Stuck? Wire can help. Hints are paid for with coins you earn by finishing levels, or you can watch a short ad to get one. PHONE AND TABLET Plays in landscape. On tablets the circuit board and the list of tries sit side by side, and everything is bigger. Plays without an internet connection too. PRIVACY AND ADS • The game is free and needs reading. Menus and Wire's guidance come in 17 languages; the level stories are in English and Turkish. • No ads in the first 4 levels. From level 5, an interstitial ad may appear only after a level is finished, at most once every 3 levels and at least 3 minutes apart. Never in the middle of a level. • Ads are not personalized and are limited to content rated G (general audiences). The app never asks for tracking permission. • Optional purchases: 5 hints, 20 hints and Remove Ads. Every purchase and restore goes through a parental gate. • No account and no analytics. Progress is saved on the device only. Wire is waiting. Let's light up the town together!
