You can also expect to see fast transactions with their withdrawals being made within 24 hours if you’ve gone through all of the KYC procedures.

Slots Bonuses and Promotions

One of the best things we've found about Ignition Casino is its 25x wagering requirements on its welcome bonus. BTC users can expect a welcome bonus of up to $3,000! If you make your first deposit, you can expect a bonus of up to $2,000.

Ignition Casino is also known for having some of the best poker tournaments in the world. Each month this casino gives out $1 million in tournament prizes. If you use exclusively cryptocurrencies, you will get 25 free spins every week as well as weekly tournament tickets and 15,000 loyalty points.

The welcome bonus is spread out over your first three deposits. Take a look: 

• First Deposit: 100% match bonus up to $50
• Second Deposit: 50% match bonus up to $100
• Third Deposit: 25% match bonus up to $150

Unfortunately, there is a 45x wagering requirement for this bonus which is quite high compared to other sites. You can also only win up to $100 with your bonus money and free spins, which is a point against them.

#3. Red Dog Casino (5 Wishes): Best Welcome Bonuses & Free Spins For New Players

Red Dog casino is one of the best sites as far as welcome bonuses for slot games are concerned. This site exclusively uses games from RealTimeGaming including our favorite game, 5 Wishes.

How to Sign Up & Claim a Slot Bonus

Before you can start playing any of the best online slots for real money, you’ll need to register an account. As you’ll see in this Lucky Block sign-up tutorial, you can complete this step in less than 30 seconds.

Step 1: Sign-up to Lucky Block Casino

Visit the Lucky Block Casino website and start by clicking on the ‘Sign Up’ button. Enter your basic personal and contact information and click on ‘Sign Up & Play’ to complete registration.

Step 2: Place Your First Deposit

Click on ‘Deposit’ and use the drop-down menu to select your preferred payment method. Once you’ve chosen your preferred cryptocurrency, you’ll be provided with the appropriate wallet address and QR code. Use either of these to make the transfer from your crypto wallet into your Lucky Block Casino account.

Step 3: Start Playing Online Slots at Lucky Block Casino

Use the Lucky Block navigation menu to browse through the available slot selection. Once you find the game that you wish to play, simply click on it to launch it. You can start spinning immediately using the default wager or alter the value of your bet using the slot’s options.

Step 4: How to Get Your Lucky Block Cashback

You don’t need to enter any Lucky Block promo codes to receive your welcome bonus cashback offer. The site will automatically calculate your casino gambling results over your first seven days. If the result is a net loss, you should instantly receive the 15% cashback on the 8th day.

However, should your first seven days of gambling result in a win for you, you’ll keep all the prize money but won’t get any cashback.

Is it Legal to Play Slots Online for Real Money in the US?

Playing online slots with real money even with no deposit is allowed in the US. Whilst most states have yet to introduce any laws that make online casinos legal, most don’t forbid residents from joining offshore casinos, such as BetOnline or Wild Casino.

This means that, as a US Player, you can join most of the casinos featured in this guide and start playing slots for real. Whilst you’ll find games by notable brands, such as Betsoft and RTG, you won’t be able to play slots by Play’n GO, Microgaming, or other brands that are not legally allowed to operate in the country.

Do I Pay Tax on My Winnings?

Different US states and indeed nations across the world treat gambling winnings differently. In most cases, prizes that come as a result of playing online slots are treated as additional income for tax purposes.

In the US, some states only consider prizes above a certain threshold to be subject to tax payments. This is also true for the country’s federal tax of 24% levied on any slot winnings above $600.

How do Online Slots Work?

Online slots, including Bitcoin slots, are casino games of chance that pay out whenever one or more specific symbol combinations land on a grid. There are thousands of slots available, and whilst some accept minimum wagers of $0.05 or less, others let you bet up to $100 or more per round.

One of the main attractions of online slots is that, unlike Blackjack and other casino card games, you don’t need any prior knowledge or experience to play the game. Once you set your wager and start a new round, you can sit back and enjoy the result unfolding. If the right symbol or symbols land in the correct pattern, you’ll receive a prize automatically and instantly.

Slot payouts and bonus feature details can be found on the paytable. You’ll be able to access this through the game’s options menu.

RNG for Online Slots

Even though there is an incredible variety of slots available, they are all virtual games that are controlled by random number generators, or RNG. An RNG is a computer algorithm that provides random, fair, and unbiased results based on the developer’s criteria. This type of computer software is vetted by independent test labs for fairness and cannot be altered by any casino operator or unauthorized person.

RTP for Online Slots

Practically all online slots and casino games include the Return to Player (RTP) percentage. This number indicates the theoretical payout across thousands or more rounds. A 95% RTP, for example, signals that a player is likely to get $95 for every $100 wagered. However, this percentage offers no payout guarantee and every spin can result in either a loss or a win of any of the available slot payouts.

Safe Payment Methods when playing for  Real Money

You can fund your online casino account using one or more of the following payment options.

Cryptocurrencies

All the listed online casinos allow you to deposit and withdraw funds using Bitcoin and Altcoins. Crypto payments are usually free of processing fees and are processed quicker than fiat currency alternatives.

Debit/Credit Cards

Most online casinos let you fund your account with top cards, including Visa and Mastercard. These options are instant, but they may also include an additional charge. However, they are rarely a payout method, so you’d need to use an alternative.

eWallets

When online casinos first appeared on the Internet, eWallets, including PayPal and Skrill, provided an instant and convenient way to deposit and withdraw funds. Today, however, this payment method has become unpopular due to the high fees associated with it.

Bank Transfers

You can withdraw and sometimes even deposit funds using bank wire transfers. This payment option is familiar but is also slow and relatively inconvenient. Moreover, charges normally apply for using it.
