(From the publisher:) A ten minute game of interplanetary invasion for two, played using fleets of seven coins on the moons of Jupiter. You've transported a ship to an enemy planet -- now what? Their teleport pad is under tight control. Looks like you'll have to overwhelm them with sheer numbers and do battle to the death to even send a single ship back home. You'll need cunning, and a good dose of luck to get through this alive -- and don't forget that special power you have up your sleeve... Sound complicated? Not to worry. You can always just use their entire planet as a place to put your drink.International readers should note that the components of Cosmic Coasters are printed paper fiber: Americans use 'coaster' interchangeably to include what elsewhere might be called 'beermats.' - BoardGameGeek
