It is totally free. It is a different fantasy game in that players act as investors, day traders, or owners instead of acting as a General Manager or Coach. Instead of a dividend, a purse is paid to the players having shares of the team winning their league championship. There is no limit on the amount of trades made or when they are made. Players can have as many accounts as they wish.
Players play directly against each other instead of against the house odds.
Groups can play against other groups.
