Sleeper Review & Expert Rating For March 2025

Let me kick things off with a little run-through of what is to be expected from the Sleeper bonus. As a new user, I was able to unlock a 100% matched bonus of up to $100 – provided I first downloaded the mobile app.

Next, I needed to create a username and password, and enter my email address before verifying my account. This was all soon followed by linking my US checking or savings account, entering the latest Sleeper promo code, and making my first qualifying deposit of up to $100.

Once the bonus had been released, I was free to check out the streams of paid contests and begin playing through the 1x requirement. I had a full year to meet these requirements, and my bonus bets could be used to enter all paid contests.

The Sleeper USA desktop site isn’t quite as lively as that detailed in my Rhino Bet review. However, it is equally as responsive and enjoyable to use.

I found that I could register swiftly by providing a few basic details before gaining full access to the free-to-enter fantasy league lobby. Amidst 21 additional features to help personalize the fantasy league experience, I could also learn more about the paid contests, edit my own player profile, and keep an eye on any bonuses sent to my inbox.

I also had the option of passing verification checks before downloading the mobile app and releasing the latest Sleeper bonus.

As noted in my Betfred review, the mobile experience can soon add to the overall experience. Well, over at Sleeper, I certainly felt that the time and effort had gone into making the mobile app and browser experience as immersive as possible.

The desktop browser transitioned over to the smaller screens perfectly, allowing for a simple switch between the two. In turn, I could bring my fantasy teams, edit my leagues, and send invites just as easily on the go.

When I downloaded the app, a whole new world was ready to explore. Here, I could redeem the welcome bonus and begin to search through a range of paid contests. These contests covered football, basketball, and esports. Plus, I could utilize many other features, including the chat room and mock draft to gain a better insight.

Compared to some of the top US online casinos, I didn’t find a great range of payment methods provided. With that being said, my US checking or savings account had already been linked to my player account, so deposits were quick to complete. Currently, I could choose either Visa, Discover, or bank transfer and daily deposits were capped at $1,000. Unless I lived in MA, where I’d be capped at $1,000 for the month.

When it comes to withdrawals, things are just as straightforward. Provided I had met the bonus requirements, I would be free to withdraw up to $1,000 in one go. Throughout a 24-hour period, I could request up to 5 withdrawals, totaling $5,000.

In this next section of my Sleeper review, I wanted to ensure that the support was put to the test. At the time of writing, I found a couple of ways to get in contact, including live chat and email. Plus, the site provided me with plenty of answers to the most common questions asked.

When clicking on the support tab, I found a number of articles and answers relating to key areas of the site. For instance, I could find out how to make use of the mock draft, pick up tips on the latest football contests, and discover how to edit and personalize the fantasy leagues.

For something relating to my account, I wasted no time clicking on the chat box. Here, I could directly contact a member of staff. I found responses were prompt and professional at all times. Alternatively, I could take time to attach relevant documents/files and send an email.

As mentioned already within my Sleeper review, the platform is split into two. I found that you can enter fantasy leagues for free across most of the US, or download the app and enter paid contests.

Paid contests are unavailable in Arizona, Connecticut, Delaware, Hawaii, Idaho, Iowa, Indiana, Louisiana, Maine, Michigan, Missouri, Mississippi, Montana, Nevada, New Hampshire, New Jersey, Ohio, Pennsylvania, Tennessee, and Washington.

Both the site and mobile app are owned and operated by Biltz Studios, Inc., backed by the latest encryption technology, and provide a selection of safer gaming tools. I found that you’ll just need to email support to implement them.

DFS sites, like Sleeper, aren’t renowned for offering a wide range of promotions when compared with US sports betting sites. However, I did manage to locate a few exciting promotions available to all of Sleeper’s app users.

The first is a protected pick. As the name suggests, I was able to protect one leg of my entry. Regardless of the outcome, it would still act as a winning leg or would allow me to receive my entry fee back. I also found a number of payout boosts and other rewards leading up to the start of major contests. Plus, the Sleeper’s X (formerly known as Twitter) account regularly released if/when promotions. In short, IF I could meet X requirements, THEN I would win X reward – simple but effective.
