Gameday: How does Rivals work on Underdog?
Underdog Rivals is based on a specific stat relating to two rival players. You have to choose which of the players will achieve the higher stat in their upcoming game. For example, a Rivals entry could be ‘Dak Prescott vs Russell Wilson’. You have to predict which quarterback will achieve the higher passing yards total in their next game.
Underdog Rivals rules require you to make between two and five predictions when you enter a contest. If you get all of your higher or lower predictions correct, you win a cash prize. Here are the prizes you can win:

A winning gameplan: Ultimate tips for playing Underdog Rivals
Underdog Rivals is a lot of fun to play, but finding winning entries requires plenty of skill and sound judgment. To help you out, our experts have put together three ultimate tips:
Play the matchups
Joe Burrow is clearly a better quarterback than Gardner Minshew, but that does not necessarily mean that he is going to throw for more yards in his next game. What if Burrow is playing against an elite defense and Minshew is facing an injury-ravaged secondary? Suddenly the chances of Minshew achieving the higher stats seem pretty good. Always look at the opposition before making your Underdog Rivals decisions.
Assess the conditions
Similarly, if Burrow’s game is expected to be played in a snowstorm or in 40mph winds, that will reduce the chance of him putting up big stats. On the other hand, if Minshew is playing in a dome, then he doesn’t need to worry about any inclement weather. Make sure you read weather reports and consider the venues when playing Underdog Rivals.
Consider the supporting cast
You also need to consider who Burrow and Minshew will be throwing the ball to. If the Bengals are missing some key receivers, then it makes it harder for Burrow to complete big plays. Always read injury reports and team news when making your Rivals picks. Remember: sometimes the obvious answer isn't the best option.
