Here’s an online game site where you can win prizes:

Net Winner

Sign up for an account, then log in to play a totally free online lottery game. Match all four numbers, plus the bonus ball, and win the progressive jackpot! Right now the jackpot stands at just a little over $1 million USD. You can win smaller cash prizes and points for matching a smaller set of numbers. Accumulate enough points, and you can redeem them for gift certificates to Target, Wal-Mart, and other big box retailers. The official rules say you need to be a US or Canadian resident at least 18 years of age to play, excluding Quebec residents.

The game does have ads on the right side of the page, and every so often you’ll be asked to type in a code to make sure you are paying attention. The fun-ness of the game makes up for the annoyances. It loads very quickly, so it’s a good way to pass some time if you have 20 minutes to spare. Just be careful to watch your time while you’re there. You could spend hours here, if you don’t watch yourself.
