The legal age for sports betting varies by country, state, and sometimes even by the specific betting platform. In many places, the legal age to engage in sports betting is 18 or 21 years old. Here are some general guidelines:

– **United States**: The legal age for sports betting is typically 21 in states where it is legal, with a few exceptions like New Jersey and Pennsylvania where it’s 18.

– **United Kingdom and Ireland**: The legal age for sports betting is 18.

– **Canada**: The legal age is typically 19, but in some provinces, it’s 18.

– **Australia**: The legal age for sports betting is 18.

– **Europe**: The legal age varies by country, with most setting it at 18, but some countries may have higher age limits.

It’s important to check the local laws and the terms of service for the betting platform you’re using to ensure you’re of legal age to bet. Betting at an age below the legal limit can result in fines, the voiding of bets, and potentially being banned from betting platforms. Always bet responsibly and within the legal framework.
