Questions About March Madness
Where can I bet on March Madness?
That depends a little on how you want to bet. There are a bunch of betting sites that allow you to place wagers on NCAA games, but if you're looking more for a bracket creator, your option are narrowed down.
The best pools and bracket challenges are -
Top NCCA Basketball Betting Sites -
- FanDuel Sportsbook
- Caesars Sportsbook
- DraftKings Sportsbook
Is NCAA Betting Legal?
Yes. And with very few, limited exceptions, it is just as legal to bet on as the NBA.
For example (really the only notable exception for current legal states), New Jersey has restricted wagering on NJ schools while they compete within the state. So if you're looking to bet on Princeton or Rutgers, you absolutely can as long as they are playing on the road outside of state lines.
Keep in mind that as more and more states come into the fold for online sports betting, there may be similar restrictions like this intended to protect the integrity of college athletics.
Is March Madness Betting Legal?
Absolutely, similar to how NCAA betting is pretty much fully accepted in the states. Creating a March Madness Bracket is one of the most popular sports betting events - and has been going on for years before sports betting was even legal.
So now that you can place real money wagers on college basketball games online, it just makes March Madness so much better!
Are there betting site bonuses for March Madness?
Not exactly. Plenty of sites offer great welcome bonuses and even basketball specific parlay boosts or insurance, but the best March Madness Promos really are the bracket pools offered by DraftKings and FanDuel, which feature huge cash prizes at the end.
