In the US, the state laws governing gambling vary widely. However, the majority of states allow online gambling. Other states have strict regulations. Regardless of the state, the most important regulation is fairness, which should be maintained by online gaming operators. Generally, most online gambling sites offer bonuses of 5% to 20% of the initial deposit, but you must wager these bonus amounts two to three times to get the full amount. In some cases, you can also win prizes if you have been a repeat customer. When you win, you can deposit your winnings into your online account, or request a certified check be sent to you.
