No. Gambling is strictly prohibited in Dubai and the UAE. Indulging in such activities may result in a penalty of AED 20,000 or imprisonment for up to 2 years.
Like all forms of gambling, online betting is prohibited under UAE law. This puts the UAE in line with other Muslim nations, most of which outlaw all types of betting. This means you won't find live casinos, lotteries, or other gambling options here either.
