When you play casino online you place wagers on games like blackjack and roulette via your computer or mobile device. The games can be played for real money or virtual credit. If you win a game, the winnings are added to your bankroll which can be withdrawn at any time. If you lose a game, the amount of your loss will be deducted from your bankroll.
When picking a casino online, make sure the site has a valid gaming licence. This is especially important if you live in a country with gambling laws that restrict the activity to licensed operators. The licensing body also determines whether or not you are eligible to make a real-money deposit.
Customer support is another important feature. A top casino will offer 24/7 support via email, phone and chat. The best online casinos also have a loyalty program that rewards loyal players with regular free spins, tournament tickets and cashback offers.
In the US, the best online casinos provide a variety of banking options. They accept popular payment services such as Visa, MasterCard, Discover and American Express. Many also offer e-wallets like PayPal and Venmo. In addition, some online casinos have a branded prepaid card that allows for quick deposits and withdrawals.
In the state of Wisconsin, there are no legal online casinos but sports betting is allowed at one tribal casino. However, legislative efforts to allow online casinos have failed. Nevertheless, it is possible that legalization may occur in the near future.
