About

Crazy Rocket

Features
Read full description

Launch into a galaxy where every trajectory is decided by real gravity. Crazy Rocket is a physics puzzle game: aim your rocket, charge the engine, and let the gravitational pull of planets, massive planets, asteroids, and black holes bend your flight path in real time. Fire the main thruster mid-flight for extra boost, but watch your fuel — every drop counts. HOW TO PLAY - Drag to set your launch angle. - Charge the engine and release to launch. - Hold the screen mid-flight to fire the thruster for an extra push. - Reach the destination planet without crashing into obstacles, falling into a black hole, or drifting off-screen. A CUSTOM PHYSICS ENGINE Every celestial body pulls on your rocket with real Newtonian gravity, simulated at 60 FPS. No two launches feel the same — small changes in angle or power lead to wildly different paths. ORBITAL LEVELS Starting at level 7, some levels drop your rocket already in orbit. You can't change the angle — only engine power and timing matter, testing a completely different kind of precision. ENDLESS, PROCEDURAL LEVELS Every level is generated from a seed, combining planets, massive planets, asteroids, and black holes into new layouts as you progress. There's always another level to master. 3-STAR SCORING - Complete the level. - Reach the destination under the target fuel amount. - Land without ever firing the thruster after launch. Chase all three stars on every level to prove your mastery of orbital mechanics. FREE TO PLAY Crazy Rocket is free with occasional ads between levels. Trajectory prediction is normally a premium feature, but you can unlock it for free anytime by watching a short ad. Go Premium to remove ads, unlock trajectory prediction permanently, and freely pan the camera to scout the whole level before you launch — gameplay and physics stay exactly the same either way. Master gravity. Chart the perfect orbit. Land your rocket. Privacy Policy: https://crazyrocket.pages.dev/privacy Terms of Use: https://crazyrocket.pages.dev/terms
