What kind of game is it?

A physics-simulation merge puzzle set in a small solar system centered on the sun. You launch meteors, ride gravity and merge planets.

How to play

• Touch anywhere on the screen and pull back like a slingshot and release to launch a meteor.
• While you're pulling, a predicted trajectory is shown, so you can tell whether it will stay in orbit, fall into the sun or fly off into deep space.
• When stars orbiting in the sun's gravity collide, ones of the same kind merge and evolve into a slightly bigger star. Different kinds bounce off.
• The merge chain is meteor, Moon, Mars, Venus, Earth, Neptune, Uranus, Saturn, Jupiter.
• Stars that fall into the sun or fly off the screen are lost.

Five modes

• Easy: make Earth to clear. The game ends after 20 collisions with the sun.
• Normal: make Jupiter to clear. Up to 50 collisions with the sun.
• Hard: a score attack that continues until game over. Up to 100 collisions.
• Fantasy: a special mode in a magical universe where star colors change. Beyond Jupiter, diamond planets, plasma planets and more appear.
• Endless: free play with no game over.

Clearing Easy unlocks Normal and Fantasy, and clearing Normal unlocks Hard and Endless. Clearing Fantasy also unlocks "Auto-Play", where the computer calculates trajectories and plays for you.

Tips
