Yes, the games really are free and there are several ways to play:
Coin Awarding Games
The better you play the more coins you earn. And not only are coins good for bragging rights, they can also benefit charity. Check out Team Challenge to learn more.
Non-Coin Awarding Games and Downloadable Games
Some games aren't able to award coins, but they're just as much fun to play. Some of these games can be accessed through the site and some must be downloaded to your computer in order for you to play them.
Pick 7 is your chance to win big. Choose 7 numbers and you could win up to $1,000,000. Invite friends to play, too and you'll win if they do!
