They also offer e-wallets and other secure payment methods. In addition, they provide a range of bonuses and promotions to attract new customers.

Casino online gaming sites feature a wide selection of slots, blackjack, roulette and video poker. Some even have live dealers. Players can also place bets on sporting events and races.

A point spread bet is placed on the margin of victory between two teams, while an over/under bet is based on the total number of points scored in a game. Other types of bets are futures and parlays, which are a combination of individual bets for a high payout.
