The Wrong Formula

60+ chalkboard levels. Drop the right formula and the world holds. Drop the wrong one and it tears apart. Fully offline. No ads, no accounts, no data collection.

A chalk-drawn physics game where wrong formulas break the universe.

You get a pile of algebraic fragments. Drag them into the formula slot. Get it right — the stickman slides down the ramp cleanly, gravity behaves, springs bounce. Get it wrong — the universe collapses. Literally. The screen tears, particles scatter, and the stickman gets ripped in half by his own broken formula.

The Wrong Formula doesn't teach you what the right answer is. It teaches you what the wrong answer looks like. When F = m × a becomes F = m + a, the units stop matching and the whole scene falls apart. You won't have to memorize why. You'll watch it happen.

WHAT'S INSIDE

• 60+ levels across four chapters • Sandbox mode — build your own scene, drop in any formula, see if it holds up • Workshop — save what you built and share it with a short text code (no server, no upload) • Cosmetic shop — earn points from levels, unlock skins, backgrounds, and death effects • Two-tier hints: a nudge, or the full derivation • Bilingual English / 简体中文, adjustable font size

WHAT'S NOT INSIDE

• No in-app purchases • No ads • No network requests (put it in airplane mode from the install screen) • No accounts, no leaderboards, no notifications, no social features • No data collection of any kind — we cannot see your progress, and neither can anyone else

DESIGNED FOR CLASSROOMS

Rated 4+. COPPA-compliant by design (we collect nothing). The share-code system means a whole classroom can exchange sandbox puzzles without any of them signing in anywhere.

A NOTE ON THE LOOK

Chalk font. Dark blackboard. Hand-drawn tokens. This app is meant to look like your physics teacher's whiteboard, not a Silicon Valley product. If that appeals to you, you're the audience.
