Fing-o-saur is a nanogame consisting of one business card which shows a map with areas containing a letter each. The active player chooses an area and says a word and a number, with the number telling how many times the letter in that area appears in the word. The other players then hit the area with their fingers ("destroy it with their meteor") while shouting the answer. A correct answer yields a point, then it's the next player's turn. First player to reach 5 points is the winner.
