Making guesses can get us in trouble, so if guessing is necessary, it's best to make it an educated guess. That's the idea behind the puzzler called Where Will It Land. In this game, you'll have access to moveable rulers and a pencil for making marks. The objective is to guess the spot the atom will land after it is finished bouncing around. This game is very addictive and will keep you guessing - but your job isn't to guess, it's to know where the atom is going. Don't forget that physics do play a huge role in the route of each atom.
