Online lotteries are free but often times you must form an account to receive any prizes. Some sites have lotto bucks which, when accumulated, are used to win prizes from their site. The odds of actually winning vary depending on how many entries are received. These lotteries can offer such prizes based on advertising revenue and name branding.

You may be contributing with a standard banner impression or a signup to a newsletter, either way you are contributing to some lump prize. It is the mass number of users in real lotteries and online lotteries that drive the prize value up. In both cases some lucky contestant may win big while the majority will lose.

A new twist to online lotteries has arrived in the form of your standard search engine. Mega Millions is a search engine that offers 10 thousand dollars daily and one million dollars a month. To win all that you have to do is form an account with Mega Millions. However, Mega Millions limits a user to 100 entries everyday. The winners are chosen at random and the contest runs until the end of March 2011.
