Free money, what more could you ask for!

Even if you aren’t a huge sports buff, you can win this game. The games are real time and questions pop up as the game is happening, no cheating or worrying that someone might be rigging the game. It’s by far one of the best sports trivia style apps out there, winnings can vary by how many people get to the designated amount for the game. I’ve won $4 and up to close to $100 per game. With 3+ games a week you can really rake in some cash. The devs are amazing, I had the opportunity to give my input on the app and was surprised by how much change they applied once the app went out of development. They listen, they care & they change the app to make things better for their players. Can’t wait to see what the future holds for Sideline 🤙🏻

Free Money and Enjoyable App

This app asks you questions real time in game and has games every week for basketball and football. For me watching a game while playing sideline makes it the game more enjoyable because I’m paying attention to details I usually wouldn’t, like if Harden scores his 27th point with a 3 pointer, 2 pointer, or free throw or how many passes Patrick Mahomes completes in his next ten throws. I’ve had the app for about two months and have already won $40 and some games I’ve won I wasn’t even watching the game and just blindly guessing, so even if you’re not a huge sports fan you can still win, overall great app.

Amazing app

Simply put, this is the best sports app in the App Store. It’s the only app that allows you to have live predicting action while getting paid, making watching the game even more fun, worthwhile, and lucrative 🤑. I have been here since the beginning and I can only saw great things about all of the great features on the app, including live updates, box scores, and the all-mighty ref bringing even more interest into the app. 5/5 ⭐️ ⭐️ ⭐️ ⭐️ ⭐️ without question and you gotta download this app to win that 💰 💰.
