Most states in the US have online lottery websites where people can check for winning numbers and get information on where to buy tickets in person. In addition, some online lotteries have expanded their offerings to include Instant Games, casino-like games where players can bet money and win prizes. These games can be played online or through mobile apps.

In the early years, states were reluctant to allow online lottery sales due to legal concerns. They feared that online lottery sales would violate the Wire Act, which prohibits interstate wire communications. However, the US Department of Justice has clarified its position and has now given permission to states to operate online lottery games. Some states have developed their own lotto online apps while others defer to third-party applications. Currently, seven US states allow online lottery sales, including Illinois and Puerto Rico.

Licensed lottery sites offer a secure environment and plenty of games and promotions. They offer national and state-level lottery games. Legitimate lottery websites also offer scratchcards, keno, raffles, and discount tickets. In addition, some sites offer lottery syndicates. They also offer secure payment options, such as Visa, MasterCard, PayPal, and ACH.

While the online lottery industry has exploded in recent years, many states have legalized the game. New Hampshire, for example, legalized online lotteries last summer and offers e-Instant games that players can play on a mobile device. Other states are currently considering legalizing online lottery games, including Rhode Island, Massachusetts, and New Jersey.
