Maine is adopting rules about daily fantasy sports games.

According to the Associated Press the proposal passed the Maine Legislature in June and became law last week without Gov. Paul LePage's signature. The proposal says fantasy contest operators must be authorized to do business in Maine and pay a fee of 10 percent of gross fantasy contest revenues for the preceding 12 months, up to $5,000.

Fantasy sports companies DraftKings and FanDuel say in a joint statement that the adoption of a regulatory framework is good for both players and business. They say it will "protect consumers and help a booming piece of the tech economy continue to grow."

The companies say 15 states have adopted regulations about fantasy according to AP.
