Astronomy Bubbles is an easy, but however a strategic puzzle game. Rules of the game: * Collect 2 or more closely spaced planets or stars from the same type to clear them away from the playing field. * Get scores for every collected luminary and accomplish a new high score. * For every collected star you get a bonus score. * Collect 50 bonus scores to unlock the supernova. * Collect 5 or more stars at once to get the double bonus scores for this move. * After collecting 50 bonus scores in the title bar appears a supernova. Click on the supernova to activate it and click again on the playing field (on one of the stars or planets) to place the supernova.
