Read full descriptionHide full description
Launch the satellites by your finger and try to bring them into orbit around the star. You need to run them so that the flight path goes through energy blocks (bonuses). For each collected energy unit (bonus), you get 1 point. Accumulated points can be spent on tips: You will see the prospective path of flight before the launching of the satellite. For changing the size of the launching satellite hold your finger on the screen. The number of satellites is limited. During the game you can change the scale, to see the whole flight path. Levels gradually become more complex and new elements appears: - Star - Satellite - Antigravity - Power unit (bonus) - Dangerous ray. Avoid it! - Boom. Here you need to push two satellites.

Zoom from a planet's surface out to distant galaxies, then reshape the whole system with your own hands. Solar System Sim is a real-time gravity sandbox built on Newton's laws and real astronomical data. Every body you add, move or destroy recalculates the orbits of everything else, live. • Smash worlds together: impact craters carve into the surface, firestorms sweep the globe, and glowing debris rains back down. • Build your own universe: add planets, moons, asteroids and comets with their own size, mass and looks, or customise the ones already there. • Land anywhere: drop to a first-person view on any planet's surface and experience its environment. • Sculpt rings: add particle rings and watch gravity shape them in real time. • Witness real eclipses: solar and lunar, with real-world astronomical precision. • Follow comets: watch them streak past and interact with the bodies they meet. • Leave the Solar System: travel to remarkable nearby stars and find them within the Milky Way. • Feel the scale: see the true vastness of space, from a pebble-sized moon to the nearest galaxies. Whether you're here to learn how gravity really works or just to break planets with it, explore at your own pace. Start your cosmic adventure with Solar System Sim.

Verdict
The clearest difference is in-app purchases: Crazy Orbits. Universe at none against Solar System Sim's 5. Crazy Orbits. Universe also leads on iOS requirement (8.1 vs 15.0). Solar System Sim's advantage is update cadence (every 5 days vs every 32 months). On price, ads and device support there is nothing between them.
