Who is this bet365 promo for?

Covers BetSmart Rating
Player reviews
"The bet365 app is very easy to navigate, and placing bets is as easy as can be. It offers tons of wager options and is extremely easy to use any bet credits you have, but it’s just such a visually boring app.”
“bet365 is one of the best sportsbooks available, without question. What makes the bet365 app among the finest: Prompt payouts, fair odds, decent promotions, a plethora of wagering options, and cash-out early features that exceed what most of the competition is offering.”

- Small bet-and-get offer: The $100 bonus is locked in, yet it pales next to the bigger hauls some rivals dish out with similar deals.

“I have an account with DraftKings, and it's been a great experience being able to have access to this kind of opportunity to bet and win from your home.”
“The app itself is relatively slow. The profit boosts are nice and unlike anything I’ve ever seen on any other app or site. So that’s a plus. The lag on placing bets is a bit annoying, but it’s understandable. The UI is nice, and the social hub is a huge plus and extremely underrated.”

Current March Madness betting odds
As the Bracket draws near, the March Madness 2025 odds are heating up; the Auburn Tigers are the favorite to win the NCAA men's basketball national championship at +300, closely followed by the Duke Blue Devils at +400.
Last year, the UConn Huskies claimed the title, defeating Purdue 75-60 for their second consecutive championship. This season, their odds have lengthened after a shaky start, reflecting a shift in the landscape. Behind Auburn and Duke, teams like the Houston Cougars, Florida Gators, and Alabama Crimson Tide round out the top contenders. Auburn’s consistent dominance — highlighted by a key road win over Alabama — and Duke’s star power, led by Cooper Flagg, drive their frontrunner status.
The odds reflect a dynamic race, with Selection Sunday set for March 16, promising more twists as the college basketball season intensifies for sports bettors.
