"Dancing with the Stars" season 25 kicks off at 8 p.m. ET on Monday, September 18. In addition to voting for your favorite couples, ABC has created a 'DWTS' Fantasy League game that will allow fans to predict which couple will win the Mirrorball trophy.

The fantasy league has some serious perks. According to ABC, a trip for four to Disney's Aulani resort in Hawaii, "Dancing with the Stars" fans will have a chance to win a slew of other prizes.

What is the 'DWTS' fantasy league?

If you watch ABC's "The Bachelor" you may be familiar with the game. The reality dating show has its own league each season where fans predict which contestant will make it to the final rose ceremony.

The "Dancing with the Stars" version is similar but fans will make their picks based on which couple they think will win the season 25 Mirrorball trophy.

The 25th season of "Dancing with the Stars" marks the first time ABC has offered a fantasy league game. It's easy to play and fans will earn points their predictions. Aside from being fun to play (especially during a "DWTS" viewing party), the points you earn will be entered into a drawing for prizes that include the trip to Hawaii mentioned above.

How do you play and what are the prizes?

The season premiere will air September 18. Fans can start playing the weekly fantasy league game on September 19 on the official "DWTS" Fantasy League website (ABC.com/DFL).

Keep in mind, you can change your predictions weekly until the game closes out on Monday, October 9 at 1:59 p.m. ET.

For example, if you initially predict Drew Scott and Emma Slater will win the Mirrorball trophy but change your mind the following week and choose Terrell Owens and Cheryl Burke, you can change your picks on the site noted above.

Every time you play the game, you earn points that equal an entry into the "Dancing with the Stars" Fantasy League game. Throughout the season, there is a weekly game that closes out at 1:59 p.m. ET on Mondays. As stated above, all final predictions will be locked in on October 9.

Game rules are explained in detail on the ABC.com/DFL website where you will find information on how to earn extra points in the weekly game.

Those extra points may pay off for three lucky fans. The grand prize (trip for four to Hawaii) will be awarded to one winner and is valued at more than $5500. ABC is offering a "Dancing with the Stars" prize pack to two first place winners. The prize includes a "DWTS" robe, bag, and beach towel.
