Although the United States government is far from licensing and regulating online gambling on a federal level, US citizens are still free to seek out and play fun and real money games on many of the worlds most popular and lucrative online casinos sites.

These USA online casinos are licensed and regulated by reputable offshore online gaming jurisdictions and renowned for their diverse game selections, trusted banking methods and generous bonuses, in some cases, USA casino no deposit bonus offers.

These US no deposit online casino bonuses are a big drawcard for online gamblers from the United States because they allow them to try out a casino and many of its most popular real money games 100% for free no deposit required, no obligation to stay.

On this page youll find everything you need to know about the best USA online casinos, no deposit bonuses (for online and mobile casinos), how to claim no deposit bonuses, what are bonus codes, the leading US-friendly casino software vendors and more.

Read on to find out more about online casino gambling in the USA, the US- friendly software providers and the bonuses available to US players, especially about the lucrative USA no deposit casino bonus.

These are online casinos bonuses US players can claim and use without depositing. They are only available at online and mobile casinos that accept Americans, and can be used to play one or multiple casino games including slots, table games and others.

Not to be confused with regular percentage-based US welcome / sign up / new player bonus offers which always require an initial deposit to unlock them, no deposit bonuses are much smaller because they are 100% free cash that range from $10 to $50.

Claiming no deposit US casino bonuses is very quick and easy. All you have to do is take a minute to register for a new real money account by filling out your name, phone number, email address, physical address, date of birth and a few other details.

When youve chosen a username and password, opted in for your free no deposit bonus, and agreed to the casino TCs, you can submit your new account application. Once your account has been approved and verified, you can use your free bonus.

As soon as youve logged into your respective USA online casino, start looking for the on-screen instructions or prompts to access and play your new bonus. If you cant find it, just contact the casino support and a friendly consultant should assist you.

You may come across USA casino no deposit bonuses that require special bonus codes to unlock them. These are identical to regular no deposit bonuses except to unlock them you have to copy and paste or type a special code into the required field.

Bonus codes are usually listed right next to the respective bonus on a US casinos homepage or in its bonus / promotion page. In cases where no deposit bonus offers are emailed to you, youll find the code listed in the same email for you to copy and paste.

The point of no deposit US bonus codes is to add some more excitement to the proceedings, but theres no difference between no deposit bonuses that require special codes to unlock, and those that dont. Its up to the preference of the online casino.

These are similar to US no deposit online casino bonus offers. However, instead of offering you a nominal amount of free cash, they offer you a number of free spins (usually between 10 and 100) you can use on one or more slots at casinos accepting US players.

Like their free cash counterparts, to claim US no deposit free spins bonuses all you have to do is sign up for a real money account at any US-friendly online casino offering them, login using your new username and password and proceed to claim your free spins.

If you cant find a tab or prompt to activate your free spins, visit the game lobby and click on any slot game (or the particular slot if specified in the free spins bonus offer) to see if your free spins have been pre-loaded. If not, contact casino support for assistance.

Whether you choose to claim a US no deposit cash bonus or a no deposit free spins bonus, be aware that any and all online casino bonuses come with terms and conditions attached. These are the rules you must follow when using free bonus cash or free spins.

US no deposit bonus terms and conditions like all casino bonus TCs must be followed to a tee if you want to get the most of your bonus play, i.e. real cash money. Thats right, play your cards right, so to speak, and you could withdrawal your bonus winnings.

All no deposit bonuses free spins or cash have their own wagering requirements that are listed under their TCs. This is the minimum number of times you must play through or bet the cash bonus (or free spins winnings) before the casino lets you cash it out.

For instance, in the case of US no deposit bonus of $20 with a 25x wagering requirement, you must make at least $500 ($20 x 25) in bets before you can request a withdrawal. Plus there are other TCs you must adhere to if you want to cash out successfully.

This includes the maximum winnings clause, which is where the amount you can cash out is capped regardless of how much you win. So even if you win $1,000, if the winnings cap is set at $50 in the bonus terms and conditions, $50 is all youll be able to withdraw.

This is why its crucial to read the terms and conditions and wagering requirements of every no deposit USA bonus youre interested in before claiming. If you fail to adhere to the TCs, you risk losing your bonus, your winnings and even your casino membership.

Players may only claim and use one casino bonus at a time

Withdrawable winnings are subject to a specified cap or limit

Players may be required to use their free bonus / spins on specific games

Bonuses may not be claimed by players with multiple or linked casino accounts

Players may be asked by the casino to provide copies of their ID and/or other documents if cashing out their no deposit bonus winnings.

The casino can cancel the bonus if the wagering requirements are not fulfilled.

When the Unlawful Internet Gambling Enforcement Act (UIGEA) was signed into law in the United States in 2006 (See our article on the current state of US online casino gambling law), it dramatically changed the landscape of online gambling for US players.

For instance, post UIGEA the majority of the worlds leading online casino software vendors and by association the websites they supplied stopped accepting American players. This meant that US online casino fans had fewer online casinos they could play at.

However, all was not lost as a handful of online gambling software vendors never stopped accepting US players then, and still accept them today.

Chief amongst these is Realtime Gaming (RTG) and Rival Gaming, two top non-American online casino software firms that for over a decade have made hundreds of world class and lucrative casino games available to online gambling fans based in America and beyond.

Over the years various other software developers have joined the list of US-friendly firms such as i-SoftBet, Quickspin and Play n GO. Between these leading firms and RTG and Rival, US online casino fans have plenty of high quality and worthwhile games to choose from.

Originally launched in 1998 in the United States, Realtime Gaming (RTG) is a pioneer of the casino software industry that supplies many high-ranking casinos that accept US players. As one of the largest privately-owned software vendors, it supplies casino games and variants with fair and competitive pay-out percentages to over 25 casinos.

RTG is probably best known for its Real Series of online slot games that are renowned for their high quality themes, graphics, features and generous pay-outs. Notable video slots from its Real Series include Spirit of the Inca, Caesars Empire, Builder Beaver, Basketbull, The Big Bopper, Bulls and Bears, Cash Bandits and Bubble Bubble.

Launched in 2006, Rival Gaming a.k.a. Rival Powered is a Cypriot-based US-friendly online gambling software firm that provides it suite of cutting edge games to more than 30 online casinos. In its over 10 years in business, Rival has developed over 200 casino games in 11 languages which it supplies to 52 globally hosted online casinos.

Its offerings include 3 reel slots, 5 reel slots, i-Slots, progressive jackpot slots, table games (such as Craps, Blackjack, American Roulette, European Roulette and RideEm Poker), video poker titles, specialty games (including Keno, Instant Bingo and Sudoku ) and a suite of mobile games like Beach Bums, Arabian Tales and Big Cash Win.

Founded in 2010, UK-based online and mobile casino software firm i-SoftBet is one of the newer gaming vendors in operation that welcomes players from the US. Certified in the UK, Spain, Alderney, Belgium, Italy and Portugal, it provides games to many globally popular online casinos, typically alongside titles from other leading vendors.

Its instant play games are designed in HTML5 so they dont need to be downloaded and can be played on desktop and mobile platforms. i-SoftBet produces many types of table games and slot games, but its most popular offerings are its branded (film, TV or book-inspired) slots such as Basic Instinct, Rambo, Beverly Hills 90210 and Platoon.

Launched in 2011 in Sweden, and bought in 2016 by rival casino software vendor Playtech, Quickspin is a 100% online and mobile slot game developer. Its known for its limited but entertaining and lucrative games that are accessible to American online casino players. To date it has released 30 desktop and 24 mobile slots laden with features.

Despite its small game selection, it has won a multitude of gaming industry awards such as Game of the Year, Rising Star, Social Gaming Supplier and RNG Casino Software. Particularly popular titles include Phoenix Sun, Mayana, Fairy Gate, Sticky Bandits, Hot Sync, Goldilocks, Wins of Fortune, Leprechaun Hills, Sakura Fortune and Treasure Island.

Founded in Sweden in 1997, Play n GO has been part of the global online casino industry for over two decades, and is a favourite game developer amongst US players. The reason for this is its portfolio of high quality, high paying games that range from all types of slots to video poker to Roulette to Blackjack to Casino HoldEm to HiLo and more.

Youll generally find Play n GO games alongside those of many other top-rated vendors at leading instant play online and mobile casinos because they are fun, graphically rich and offer worthwhile pay-outs. Standout slots include Aztec Warrior Princess, Viking Runecraft, Matsuri, Prissy Princess, Jade Magician, 7 Sins, Bugs Party and Flying Pigs.

Today all of the worlds premier online casinos have mobile counterparts that can be played on smart phones and devices most USA online casinos included. Due to instant play HTML5 games that require no download, few computer, laptop or mobile devices are off limits.

And just as Americans can access and play at online casinos on their favourite platform, so too can they unlock the most worthy US no deposit bonuses. On casinos with both facilities, players can use the same login details to use their bonus, deposit, play and cash out.

In some cases, players can even activate their no deposit cash or free spins bonus on their desktop computer, and continue where they left off on their mobile device. Never before has claiming and playing no deposit casino bonuses been so quick and convenient.

Plus, if an online casino has a mobile facility, players can typically access it regardless of the smart phone or tablet they own or what operating system theyre running on (like Android, iOS, Windows, or Blackberry). All they need is a connection via Wi-Fi, LTE, 4G or 3G.
