NJ Online Casinos

New Jersey is the state that offers the biggest variety in terms of online casino choices. Here are the top operators:

PA Online Casinos

The Keystone State is relatively new to online gambling. At the moment, you can only play online games in Pennsylvania with Hollywood Casino, BetRivers, Parx Casino or the PA iLottery.

WV Online Casinos

Despite being one of the first states to legalize online gambling, the Mountain State does not currently offer any WV Online Casinos. Hopefully, some of the land-based casinos operating in the state will be applying for licenses to offer online and mobile gaming platforms.

NV Online Casinos

Even though it was exempt from the PASPA regulations, the Silver State has not fully embraced the online gambling opportunities. NV online casinos are limited to online poker, available through the WSOP platform.

DE Online Casinos

Delaware was the first state to legalize online gambling. The state’s three land-based casinos now offer DE online casino platforms:

  • Delaware Park Casino
  • Harrington Casino
  • DoubleDown Casino

What kind of online bonuses are there?

Usually, in order to attract new players, the most common online casinos offer generous casino welcome bonuses.

We’ve listed a few types that are easily found online:

  • “No deposit bonus”: meaning that you get a certain amount of bonus money you can use to keep on playing at online casino games;
  • “Match deposit bonus”: in this case a legal online casino will give you an amount of credit that is equal to a predefined percentage of your first deposit, for instance up to 100% and so on;
  • “Free Spins bonus”: this type of bonus can only be used on slots, meaning you would be given a certain number of free spins and you could use them on a previously determined game.

There are a few other types of bonuses online, but what a casino will offer you once registered is up to the operator itself to decide. One thing is certain, there are always some wagering requirements you need to meet when it comes to online gambling and bonuses.
*Always read the fine print and the terms of an offer before you activate it.
