Some common types of illegal gambling activities happening online include underground online casinos that offer a wide range of games, such as blackjack, roulette, and slot machines. These sites can be accessed through hidden networks and encrypted connections to avoid detection. There are also illegal sports betting operations that allow users to place bets on various sports events without any regulatory oversight. Additionally, there are unlicensed poker rooms and lotteries that operate outside the legal framework, often targeting unsuspecting individuals.
