Drop and merge planets to create your ultimate galaxy in this space-themed puzzle game. Compete in the leaderboard with unique abilities and planets, and play your way with normal, vanilla and chaos modes. But always make sure your planets don't go over the limit.
Drop planets to combine them. If they go over the limit, you lose and they explode!

If you want to reset, then create a black hole (which also forms after you combine two suns). However, if you use this ability it will half your points and it only works once a game so choose when to use it carefully.

To get extra points, try to chain multiple planet combinations together to get a combo bonus.

There's a total of 4 abilities at your disposal. Another example, is the lightning, which destroys any planet it strikes.
