You get parts. You get one board. What happens next is entirely your fault.
Planks, springs, fans, magnets, cannons, conveyors, rubber-duck dynamite. Place them anywhere. Rotate them. Regret nothing.
Then take your hands off the keyboard — you get no control after launch. Fifteen seconds of pure cause and effect.
Airtime, near-misses, chain reactions, parts left unused, photo finishes. Winning ugly is fine. Winning gloriously is the game.
Same board, same parts, everyone on Earth — new at midnight, your midnight.
Every solve produces a share card and a 15-second replay. Post it. Your friends will see your score, watch your beautiful dumb contraption work, and lose their afternoon trying to beat it.
Keep your 🔥 streak alive daily, then face the Weekly Master — a boss-sized remix that separates the builders from the button-pressers.
A campaign that keeps changing the rules just when you think you’ve learned them.
Deterministic physics means your run is YOUR run — same build, same result, every single time. That’s what makes replays, daily fairness, and bragging rights real.
Kings that panic and flee from your marble. Shielded emperors. Sentry turrets that track you. Patrol drones with opinions. They’re not obstacles — they’re opponents.
Pressure plates, levers, laser tripwires — wired to gates, pistons, and freight elevators. Late-game levels are contraptions you finish, Incredible-Machine style.
Buoyancy that carries your build. Gravity that runs on switches. Breakable glass, spinning mills, portals, wind. Fifteen worlds, each with a new law of nature.
Every best run is saved and rewatchable in cinema mode — and downloadable as a clip. Your greatest disasters deserve an archive.
Every level hides a second, harder goal — win with zero parts, ride an explosion, never touch the ground. 150 diamonds for the obsessed.
Two meters judge every run. Minimalist genius and maximalist mayhem both score — the game just wants you to commit.
No subscription. No ads. Never pay-to-win.
No — and it can’t be. Everyone gets identical parts on identical boards. Supporter buys more worlds and cosmetic flair, never an advantage. Daily leaderboard bragging rights are earned with brains only.
Forever. The Daily Puzzle and Weekly Masters are free for everyone, always. That’s a promise printed inside the game itself.
