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.
