The Line Card Game

Guess the numbers, fill in the Line. How much does a great white shark weigh? How far is the Earth from the Moon? How hot is the surface of Mercury? These figures have nothing to do with each other, but if you had to classify them, where would you put them on the Line? The Line's principle is simple: each card has a piece of information on the front, and its corresponding numerical value on the back. Estimate the value, and place it correctly on a scale made up of the previous cards. In co-op mode, line up as many cards as possible! In competitive mode, be the first to get rid of all your cards!
