Logic Gates Puzzle

Every puzzle now shows its goal as a picture and marks the cases you already solved — no guessing what the level wants. Worlds 1–3 free.

Logic Gates Puzzle turns the building blocks of computer science into a hands-on game for kids. Drag gates, connect wires, watch the electricity flow, and light up the bulb — all while learning how real computers think.

Built for curious kids ages 7–12 (and grown-ups who love a good brain teaser), every level is a tiny circuit to solve. There's nothing to read to get started — a friendly guide shows you how, then you're building logic on your own.

WHAT YOUR CHILD LEARNS • AND, OR, and NOT — the logic behind every app, game, and computer • XOR, NAND, and NOR as they level up • Problem-solving, sequencing, and cause-and-effect • The foundations of coding and STEM, through play

FEATURES • See exactly what to build — every puzzle shows its goal as a picture, not a riddle • Live feedback: the board marks which cases you already got right, so you're never stuck guessing • 7 worlds that each introduce one new gate or one new idea • Drag-and-drop gates and wires — tap to connect or pull a wire, whatever feels natural • Watch signals flow and the bulb light up in real time • Gentle hints that show one way to solve a puzzle — never the only way • Endless Mode: unlimited puzzles that get smarter as you do • Earn up to three stars for clean, efficient solutions • Designed for little fingers — no timers, no penalties, no losing

SAFE & FAIR • No ads • No tracking and no data collection • No surprise pop-ups — just puzzles

A GATEWAY TO CODING Logic gates are where computer science begins. Logic Gates Puzzle gives kids an intuitive, physical feel for how logic works long before they write a single line of code — a perfect first step toward programming and STEM.

Free to play and learn: Worlds 1–3 — a complete NOT, AND and OR course — plus unlimited Endless Mode, free forever. A single one-time purchase adds the three-switch worlds, XOR, the NAND/NOR world and the par challenges. No subscriptions, ever.
