Have you known that there is an age restriction in gambling? But it is varied among the countries in the world. I have just checked in
wikipedia that commonly someone can play gambling starting from the age of 15/16/18/19/20/21 years. It depends on where he lives, every country may have different regulation related to the age restriction. Below I classify some countries based on the age restriction:
Age 5: Malawi (Casino)
Age 15: Iceland (lottery)
Age 16: United Kingdom (Football pool, Scratchcards), Estonia (other), New Zealand (instant kiwi)
Age 18: Australia, Kiribati, Nauru, New Zealand (horse racing), Palau, Solomon Islands, Tuvalu, Vanuatu, Vanuatu, Albania, Austria, Belarus, Bulgaria, Croatia, Czech Republic, Denmark, Faroe Islands, Finland, France, Germany, Gibraltar, México, etc
Age 19: South Korea, Canada, USA
Age 20: New Zealand (Casino), Sweden (Casino), Japan, Nigeria
Age 21: Belgium, Estonia (Casino), Armenia, India, Lebanon, Macau, Malaysia, Philippines (casino), Singapore, Taiwan, Vietnam, Cote d'Ivoire, Egypt, Namibia, Niger (casino), Bahamas, Saint Kitts and Nevis, US Virgin Islands (casino), USA, Macau

Source & more detail information: https://en.wikipedia.org/wiki/Gambling_age#cite_note-27I cannot say that it is true that Malawi Allows an age 5 to gamble, because the source is the Wikipedia (articles may edit it for free), also age 5 cannot read nor write in a straight language or can compute but this one is acceptable if the IQ of that kid is high, but then I do not think that it is good for a teenager or a child to play in that age, also 18 above is more good since, they can be put in jail if they are disobeying laws regarding gambling.
