The different ball in terms of weight

Cricket, Football, Volleyball, Tennis, Baseball and many other games are incomplete without the balls. Now, think that certain number of one of these kind of balls are here with you. All these balls are supposed to have same weight. But, due to malfunction in producing of one ball, its weight is more than all other balls.
You are given 80 seemingly identical tennis balls, but one of them weighs slightly more than the others. You are given with a weight balance and are supposed to have a  number of tries to find the one ball with the heavier weight. You have to use minimum number of attempts to get to this heavy ball. Consider only worst case scenario. Ie, you are not supposed to think that you will find the heavier ball in only one attempt. Consider all the scenarios together. This is the kind of puzzle, which requires a certain amount of hard work to reach to the answer. The number of balls is a big number.

But, if you can not work with this huge number, try to work with smaller number of balls. For example, start solving with 12 balls or 20 balls. And, try to find the logic behind all these kind of riddles. You will surely get the logic which is true for any number of balls given. Find that logic and then you will be able to solve this kind of puzzle with any number given - no matter whether it is too big or too small. You will be able to solve that puzzle. All the best for solving this puzzle. Try hard, harder and hardest. Don't try to surf the answers through Internet, as this kind of puzzle will definitely be available to you with solution on Search Engine. Try to solve this interesting puzzle by yourself.
