Casino online is the name given to sites that offer real money gambling games via desktop and mobile devices. These include slots, video poker, blackjack, roulette, baccarat and other traditional casino favorites. Some sites also feature more unique or game-show style offerings. The best casinos online are licensed and take responsible gaming seriously. Players can impose deposit and loss limits, time out from their account or self-exclude if they become problem gamblers.

Besides the standard casino games, some online operators offer sports betting, horse racing and other non-traditional betting options. These include accumulator bets that combine multiple individual wagers for a larger payout. Other popular wagers include point spreads, over/under bets and futures. These bets allow players to predict a winner by picking either the underdog or the favorite.

Some of the leading casinos online feature high RTP slot games, live dealer tables and other titles with a competitive house edge. Some also feature progressive jackpots and Megaways games, which can multiply winnings by up to a hundredfold. Other notable games at top casino sites include a variety of keno variants, virtual scratch cards and Sic-Bo.

The best casino sites accept a range of payment methods, including credit/debit cards, e-wallets and cryptocurrency. Some sites may charge a fee for card transactions, but most do not. E-wallets are particularly popular at casino online, as they usually process deposits and withdrawals much faster than other methods. They also often have much bigger withdrawal limits than banks do.
