Stack and Slash vs Logic Gates

Stack & Slash is a pixel-art puzzle game where the puzzles are real code. Pick one of five developer heroes — and every puzzle appears in their language. Lukasz reads JavaScript, Jacek reads C, Paula reads Python, Radek reads SQL, and Mateusz keeps it to clean pseudocode. Same puzzles, equal difficulty, five different skins. READ THE CODE, SLASH THE BUG • Predict what a snippet prints • Spot the bug hiding in plain sight • Reorder shuffled lines until the logic flows • Flip boolean switches to open the gate • Fill in the missing operator CLIMB SIX CODEBASE REGIONS From beginner-friendly Hello Hollow through Loop Lagoon, Branch Bay, Recursion Caverns and State Summit, all the way to the senior-level Null Void. Each region drills different families: arithmetic, arrays, conditionals, loops, recursion, scope and mutation. EARN YOUR STARS Three stars per region: clear it, clear it flawlessly, clear it fast. Replays rotate fresh puzzles from the same difficulty bank, so no two runs are identical. SPRINT WHEN YOU'RE READY A timed arcade mode for rapid-fire solving. Chain correct answers into combos, collect bytes, and chase your personal best. NO STRINGS ATTACHED No accounts, no ads, no in-app purchases, no tracking. Fully offline. Just you versus the code. Whether you're learning to code, teaching someone who is, or you've shipped software for twenty years and still enjoy a good "wait, what does this print?" — Stack & Slash has a hero for you.

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.
