Over React — Physics Contraption Puzzle Game

Build a contraption, mind the physics, solve the puzzle, and watch the chaos. Fun and addicting.

OVER REACT is a physics puzzle where you place planks, springs, fans, magnets, cannons, conveyors, and rubber-duck dynamite on a 2D board, then hit GO and watch your Rube Goldberg machine topple a cartoon king. Build a ridiculous contraption then watch the chaos play out and solve the puzzle. 🗓️ THE DAILY CONTRAPTION Everyone gets the same puzzle and the same parts every day. Build your streak, save your 15-second replay, and share a card that dares friends to do it better. A new Weekly Master boss level every week. 🏆 STYLE SCORING Solving is easy. Solving with style is the game. Earn points for airtime, near-misses, chain reactions, unused parts, and photo finishes. Two meters judge every run: ✨ ELEGANT vs 😈 DERANGED. Some solutions are beautiful. Some are unhinged. Both get a trophy. 🌍 150-LEVEL CAMPAIGN Journey through 15 themed worlds — Sunset Meadows, Gloom Caverns, Frost Peaks, portals, floating islands, volcanoes, clockwork turrets and drones, shielded cowardly kings, underwater buoyancy, anti-gravity, and circuit wiring with lasers and elevators — all the way to The Grand Machine. • Daily puzzle, streaks, and shareable replays • Weekly Master boss levels • The first 30 campaign levels • 150 levels across 15 worlds • Cosmetics in the Workshop No ads. No subscriptions. Deterministic physics means the same build always gives the same result, so replays are shareable and every daily puzzle is perfectly fair. Just you, a pile of physics parts, and a king who really should have seen this coming. Build something ridiculous. Press GO.
