In Mexico, the legal age to gamble varies depending on the type of gambling. For casinos and betting shops, the minimum age is 18 years old. However, for other forms of gambling such as lotteries and scratch cards, the legal age is 21 years old. It is important to verify the age requirement at each establishment before participating in any form of gambling. Failure to meet the age requirement can result in penalties or being denied access to gambling activities. Make sure to carry valid identification to confirm your age when engaging in gambling in Mexico.
