How Online Casino Bonuses are Regulated in Different States

These different market and regulatory conditions change bonuses considerably. You might not consider it an obvious link, but even things like tax rates and the number of operators can affect what kinds of bonuses casinos offer. 

This fragmented market can lead to players wondering if it is smart to find a casino bonus. The answer to that one is probably yes, but it can be confusing. For this reason, US players frequently visit casino comparison sites in order to analyze all the particular options in their jurisdiction, with bonus offers and their terms presented clearly by casino experts. As well as other factors like general reputation, payout speeds and game selections. 

This article will give a general overview of what to expect from bonuses in each state and at offshore sites. However, it's up to players to do their own research for an informed decision. 

New Jersey is the Most Mature Market 

Due to its gambling history with Atlantic City, New Jersey was one of the first states to legalize online casinos and later sports betting. It has had legalized online casinos since 2013. There are 30 licensed sites in NJ currently and it is one of the most competitive markets in the US. 

This generally means bigger and more interesting bonuses for players, while still being regulated to certain limits and terms by the New Jersey Gambling Commission. 

Pennsylvania Offers are Generally Tighter due to High Taxes 

There are currently 24 licensed online casinos in PA. It is one of the fastest-growing markets in the country, but it has a high tax rate of 54% on online slots. This means operators are squeezed on their revenues, and so sometimes can't afford to take as many risks with bonuses that might occasionally pay out big to customers. 

The Pennsylvania Gaming Control Board is the regulator in the Keystone State. It has frequently updated its guidance around certain kinds of promotions, meaning casinos choose caution over potentially having to remove or change bonuses later. 

Michigan is the Largest and Most Competitive Market 

Michigan's online casino market just keeps getting bigger. It recently overtook New Jersey in a few months as the biggest in the nation, despite only launching in 2021. It has 15 casino operators licensed in the state currently. Between them, they offer competitive bonuses, as this is a priority market for many operators.

The Michigan Gaming Control Board is the regulator, and it has often focused its efforts on expanding player protection and responsible gaming tools over restrictions on bonuses or advertising. 

West Virginia is smaller, but Bonuses Tend Bigger 

West Virginia has a smaller population than the top markets above, but it is keeping up with the growth in other markets. This means bonuses have tended towards being more competitive as there is a small but valuable player base. 

The West Virginia Lottery Commission is the regulator in the Mountain State. There are currently 10 casinos available, across five licensed operators, and potential for a further five casinos included in the 2020 legalization package. 

Delaware has Limited Casino Bonuses with It's State-Backed Model 

Delaware was actually the first state to legalize online casinos, back in 2013, but it only licensed two state-backed operators and it has stuck with that since. 

The state's relatively small population - just over one million in 2025 - has limited its potential for market growth. Meanwhile, major national operators haven't been active in trying to force change and get in on the market. 

That all means limited bonuses. The two operators usually have similar deposit match bonus offers that are smaller than those in many states, as there is less competition and fewer customers. 

Connecticut's Casino Duopoly Limits Competition 

Connecticut also only has two online casino options, with both licenses belonging to tribal casino operators based in the state. Namely, the  Mashantucket Pequot Tribe, which partnered with DraftKings, and the Mohegan Tribe's Mohegan Sun Casino.

These tribal operations have significant financial backing from successful land-based casinos, but the market hasn't shown huge growth since opening in 2021. So bonuses can be decent, although there isn't much variation between the two operators for the most part. 

Rhode Island is the Only Casino Monopoly State 

When Rhode Island became the newest state to legalize online casinos in 2024, it turned to a single operator model. This means only the legal, regulated option is Bally's, which is based in the state capital of Providence. 

Rhode Island is the nation's smallest state by land area, and has a population of just over 1.1 million. So the market already wasn't huge. With no competition to speak of, there's little need for the one operator to be competitive with its bonuses. However, it does have similar kinds of promotions available as it does in other states. 

Offshore Casinos Tend to Have the Biggest Bonuses 

Offshore casinos offer services to players in most states without regulated casino markets, operating in an international legal grey area. Although there are well-known and long-standing platforms with good reputations, these casinos are not licensed or regulated in the US, so players should tread carefully. 

On the flipside, as they're not restricted by local regulations, these casinos do offer some very high-figure bonuses and, from time to time, potentially very valuable ones. But they may have more opaque or restrictive terms, so once again, players should do their own research. 

Experts do not recommend that players in states that have a regulated market use offshore casinos. The lack of licensing means no legal recourse if things do go wrong, and general US legal standards won't apply when it comes to bonuses matching what was advertised.
