Online slots in the United States have become increasingly popular in recent years, particularly as more states have legalized online gambling. Online casinos must be licensed and regulated by state gaming commissions, and the games themselves must be audited and tested by third-party organizations to ensure that they are fair and random. While online slots are legal in some states, they are still subject to strict regulations to ensure the fairness and security of the games. There's also been a push in other states as sports betting tax revenue disappoints relative to expectations, but there's nothing imminent as of now. Some other states, such as Indiana, have considered legalization in recent years, but nothing has come of it yet. Online casinos are expected to debut in Rhode Island during the first half of 2024.

As of December, 2023, there are currently four states where online casino gambling, including online slots, is legal and regulated: Michigan, New Jersey, Pennsylvania, West Virginia, Connecticut, and Delaware. In the United States, online gambling laws are regulated on a state-by-state basis, with some states allowing online gambling while others do not.
