Online Gambling involves wagering on games of chance conducted through the Internet. It includes sports betting, lottery games, keno, casino and card games such as poker and blackjack. Online gambling also offers a variety of payment methods, although e-wallets and credit cards are the most popular choices. Different countries and states have their own regulations regarding online gambling. Some even have specific laws against it.
Internationally, an increasing number of jurisdictions are legalizing and regulating Internet gambling. This is partly due to recognition of the difficulties associated with enforcing prohibition and the benefits of regulation, such as requiring harm minimization measures, enhancing consumer protection, and generating taxation revenue. 
Although there are some concerns that the ease of access and instant feedback of Internet gambling may lead to excessive gambling, research to date has not supported such claims. A range of factors appear to be involved, including a number of game-specific characteristics, variable reinforcement, and the fact that gambling is often a form of escape from negative emotions.
Individuals who develop a problem with gambling can experience many symptoms, such as increasing amounts of time and money spent on gambling, hiding or lying about their gambling activities, neglecting other responsibilities, and making excuses to gamble. They may need to gamble with larger amounts of money in order to feel the same level of excitement and reward, or they may spend more time gambling than they intended. Identifying triggers and replacing gambling with healthy activities can help individuals to overcome these problems.
