The postseason is finally here -- and you get to play, too.

With MLB's Rally games, fans can play for the chance to win big prizes every day during the playoffs.

There are two great ways to play this postseason: MLB's daily Quick Pick contest, and the Rally app. Both are free to play.

With Quick Pick, you only need to answer seven questions for a chance to win big cash. Quick Pick asks fans to make seven predictions about what will happen in the postseason games each day. You might be asked if Fernando Tatis Jr. will get a hit, or who will have the most RBIs between Ronald Acuña Jr., Freddie Freeman and Marcell Ozuna, or how many strikeouts Yu Darvish will rack up.

There are seven questions every day. Get all seven right, and you win a share of that day's prize pool. Quick Pick is starting with a $25,000 pot this postseason -- and if there's no winner, it grows by $3,000 a night.

You can play Quick Pick every day at mlb.com/quickpick.

With the Rally app, fans can make live in-game predictions for every single at-bat of the postseason and compete to win daily prizes. Do you think Aaron Judge is about to crush a home run? Do you think Clayton Kershaw is about to strike the batter out? Make the right picks, and you could win.

For the Wild Card Series, which start Tuesday, the Rally daily prizes are $1,000 for first place, $500 for second and $100 for third.

To play, download the Rally app on the App Store at mlb.com/rally.

This postseason, there's also a brand-new feature for the Rally app: The Bonus Bar. The Bonus Bar rewards players for making correct picks in a row. To get big points, you don't just have to make a longshot prediction like a home run -- you can also earn more points for stringing together the right picks. The Bonus Bar levels the playing field for fans who want to focus on making correct picks, and the ones who like to take their chances on a big play happening.
