Countries With Legal Sports Betting For Adults Under 21

Australia

Sports betting in Australia is legal for 18-year-olds at the local level across the entire continent. All of the common varieties of sportsbooks are offered, from mobile, online, to in-person locations.

Like the United States, each region is in charge of regulating sports betting and gambling inside their respective borders. Every state has its own governing body and licensing requirements for local sportsbooks, but what they do have in common is the same minimum age of 18.

While many of our brands accept Australian punters, some of them are inaccessible while in-country. Local books may focus on regional sports like the AFL, but international sites feature NFL betting and other leagues that aren’t AUS-centric.

Canada

In August of 2021, Canadian lawmakers legalized sports betting across the country when they passed Bill C-218 (the Safe and Regulated Sports Betting Act). Every territory in Canada now offers legal sports betting.

Manitoba, Quebec, and Saskatchewan have set the minimum age for sports bets at 18, but all other regions require you to be at least 19 years old to place a wager. Sportsbooks are available at retail locations, as well as online and via mobile apps.

Many of the sites included in our 18+ sportsbook reviews also accept players in CA. There are no local or federal laws that restrict gambling online with an international betting site in Canada, so you can use them to bet on NHL games, the CFL, or any other odds that they offer.

Germany

Locally regulated sports betting in Germany is legal and available to anyone who is 18 or older. In 2021, the Fourth State Treaty on Gambling (Glücksspielstaatsvertrag) became law, reforming sports betting into its current form.

Both in-person and online sportsbooks must be licensed by the Gambling Authority (Gemeinsamen Glücksspielbehörde der Länder). DE is unique in that it charges a 5% tax on all dollars gambled, whereas most countries impose a tax on the amount won.

Offshore sportsbook sites can also be accessed in Germany. While they are not regulated by the GGL, there are no laws in place to stop them from accepting bets from gamblers in the country. There is no penalty applied to bettors that wager with an international sports betting site in Germany.

Philippines

Anyone who is 18 or older can bet on sports using a sportsbook that is regulated by the Philippine Amusement and Gaming Corporation (PAGCOR). These include land-based sportsbooks, online betting sites, and gambling venues that are based offshore.

There are several offshore sportsbooks that accept members at the age of 18, but there are a few that are restricted to players who are 20 and under, so be sure to read the terms and conditions of membership before joining.

NBA betting and other basketball leagues are extremely popular in PH, and the odds are available year-round at the books we recommend. E-sabong has been suspended since 2022 and is not typically offered at the brands listed in this guide.

Puerto Rico

Since Puerto Rico is a territory of the United States, the SCOTUS’ repeal of PASPA in 2018 also applied to them. This repeal allowed US territories to decide whether they wanted regulated sports betting to exist inside their border.

To date, despite the consideration of a sports betting bill in the PR legislature, domestic sportsbooks are not yet legal. The only way to safely and legally bet on sports in Puerto Rico is to sign up with an offshore sportsbook site.

These online gambling venues accept players as young as 18 years old, but there are a few that are limited to 21 and over bettors. The sites we list here accept players in PR at eighteen and can be used to place a wager on pro or college sports right now.

Best International Betting Apps

The online sports betting sites that we recommend in this guide offer their services using mobile phones and tablets while abroad. Most locally regulated sportsbook apps require a download to your device, but offshore gambling sites aren’t beholden to those standards.

You can log on to any book that serves that particular country using an up-to-date web browser app (Safari, Opera, Chrome, etc.). Everything that is offered on the desktop sportsbook version of the site is also available on the mobile betting app.

Each app that we feature here accepts players who are eighteen years old. While these mobile sportsbooks can offer betting odds to any international country they wish, some have opted out of certain regions due to unfavorable conditions.

Tips For International Sports Betting

❌ Don’t Use A VPN

Virtual Private Networks are very handy for viewing content that isn’t available in your home country, but when it comes to online gambling, the risk is not worth the potential reward. Online sportsbooks can cancel your account and terminate all held funds if they suspect you are using a VPN to disguise your location.

✔️ Place Bets And Get Paid With Cryptocurrency

Using cryptocurrency to fund your account and get paid sports betting winnings bypasses any local financial institutions because of the unregulated status of altcoins. These transactions are anonymous and are actually preferred by the sportsbook sites that we suggest in this guide. Furthermore, many sites feature sportsbook bonuses that are much more lucrative than when using local currencies.

✔️ Join Multiple Sportsbook Sites

If you limit yourself to a single sportsbook membership, you will only be able to place a bet on the odds that they create for games and events. By joining more than one sportsbook, you can gain access to different sets of betting odds and earn a higher payout for your dollar. This is referred to as line shopping, and it is a strategy that we use anytime we place a wager online.

Frequently Asked Questions

Which Countries Allow 18+ Sportsbooks With Live Betting Options?

While in-game betting has had a rocky history in some countries, as of 2025, we are unaware of any that forbid live wagering. This is especially true when adding offshore sportsbooks to the mix, as you can live bet at any of the 18-friendly sites we recommend.

Which Countries Have Legalized Sportsbooks Supporting Cryptocurrency Transactions?

Currently, there are active local sportsbooks in the UK, Canada, Australia, Germany, and Japan that accept cryptocurrency as a form of deposit. There are no laws against gambling with crypto in the USA, but we’ve yet to encounter a state-regulated sportsbook that accepts it.

Will I Get Arrested For Using An Offshore Sportsbook Site?

In most cases, no. If the country already allows local sports betting, then you can safely use an offshore vendor as well. For our purposes on this site, we won’t be focusing on countries that have outlawed all forms of gambling. This section of our site is designed to point out regions in which you can bet on sports at 18 in some form. We have not found any instances where law enforcement has gone after anyone for betting on sports online at a legitimate online sportsbook, even if it operates offshore. That being said, it is up to you to understand the gambling laws for the jurisdiction in which you live.

Are There Countries Where Sports Betting Is Illegal?

Yes, and a majority of them are located in Asia or the Middle East. Europe, North America, and South America contain mostly gaming friendly nations, but we advise caution anywhere else.
