Factor Game
Two players compete for high score by picking numbers from a board (screen) which are then added to their score. There is a catch though. Whenever Player A picks a number, the total of every factor of that number still showing on the screen is added to the opponent's score. When the opponent, Player B, chooses a number, that number is added to his/her score, but Player A gets the total of all remaining factors of the number B chose. Game continues until all numbers have been picked. High score wins. Number Sense, Numerical operations MW*
