Where To Bet On Basketball If You Are Under The Age Of 21
There are a few under 21 online gambling states in the USA that possess sportsbooks, but when venturing offshore, the online options become much more plentiful. Both varieties are detailed below.
Domestic - While many states have ushered in domestic sportsbooks, most of them require a minimum age of 21. Even the states that feature a minimum sports betting age of 18 are subject to venues opting to only allow 21 or older patrons to enter because they serve alcoholic beverages. Be sure to call first before making a long trek.
International - Most of the overseas basketball betting sites that have passed our rigorous examination process accept bettors at the age of 18 and can be accessed in every state in the USA save for Washington which has a prohibition in place for all online gaming.
Feel free to browse through each and every one of these 18 & over basketball sportsbook sites and see what each has to offer, including betting on the NFL and other popular US sports.
Betting On NBA Games
Under 21 NBA betting can be found at almost all offshore sportsbook sites and domestically in a select few US states. A great option for bettors between 18 and 20 years of age are the offshore sportsbook sites that we list above.
Most, but not all, of these offshore sportsbook sites allow for customers to join at the age of 18, and offer basketball odds for regular season games, NBA Playoff betting, and lines for the NBA Finals. Futures odds are also on the boards nearly year-round for NBA Champions, division winners, and more.
Betting On NCAAB College Basketball Games
Much like pro basketball, betting on NCAAB games can be done at any reputable sportsbook in existence. That said, we suggest joining up with one of the best college basketball betting sites that we’ve included links for in this guide, as they cater to the 18+ market in many ways.
Bet on March Madness odds, NCAAB conference winners, or on individual college basketball game lines 24 hours a day from the convenience of laptops and mobile devices. Read below to discover the many advantages they offer to under 21 basketball bettors in the USA.
Other Basketball Leagues To Bet On If You're 18 and Up
The NBA and NCAA College Basketball betting odds aren’t the only show in town. Check out these other international basketball betting options from around the globe that often appear at our top offshore sportsbook sites.
- WNBA (Women’s National Basketball Association)
- NBA G League (Gatorade’s NBA development league)
- Philippine Basketball Association

How To Bet On Basketball Online If You Are Under 21
Since most domestic online sportsbooks that offer basketball odds on the NBA and NCAAB are 21+, we recommend utilizing the premium services of one of the sports betting sites we’ve linked to on this page.
Wagering on basketball odds at an offshore sportsbook site requires creating a membership which can be completed easily.
- Click through each of the NBA and NCAAB sportsbook sites we’ve included in the table above and decide which basketball odds to bet on.
- Once decided, travel to that sportsbook’s homepage and click on the join icon.
- Enter accurate account data to create a user profile.
- Make your sportsbook deposit, but before you do, consider the bonus cash offers and cryptocurrency funding alternatives. Our page dedicated to 18+ sportsbook banking options will provide a greater understanding to potential online basketball bettors.
Futures odds can be placed on any sport or any occurrence. Most basketball futures odds involve the eventual overall champion, but also include division championship odds, and conference betting. These basketball futures lines will list all eligible teams and provide a moneyline on each one.
Proposition bets are wide open in what they can offer odds on. Most prop bets for NBA and NCAAB accept action on team and player statistical totals, but betting lines can be produced for anything that happens while the game is on the air, and we mean anything.
Popular games will inspire oddsmakers to create more ambitious prop bets that can include how often catchphrases are uttered by the commentators, the number of commercials aired, or whether a player’s spouse will argue with the referees. The most proposition wagers are created each February for betting on the Super Bowl.
Cash Bonuses
International basketball sportsbook sites offer deposit matching bonus promotions each time accounts are funded, and when Bitcoin or cryptocurrency is used, the bonus cash escalates exponentially. Specific seasonal bonuses can be applied to under 21 football betting, basketball betting, or a major championship.
These promos are intended to entice new members to join, but acceptance is not required. Also, be sure to investigate any conditions that need to be completed to ensure that the bonus will work with your bet schedule.
Mobile Basketball Betting Apps In 2024
Domestic and offshore sportsbooks allow for basketball betting via mobile devices, but through slightly different means. Domestic sportsbook apps require a download, but the web-apps at our recommended online basketball betting sites only require a click on one of our provided links in the table above using a mobile browser.
The sportsbook web-apps we promote for mobile basketball betting are instantly accessible from anywhere in the USA with an Internet connection, and is available across all popular Apple and Android smartphones and tablets.
These apps are not limited to basketball odds, offering up options for 18+ college football betting, the NFL, NHL, MLB, and other major sports.
