Online slot bonus advice

It is important to read the fine print before claiming a bonus at a casino for playing online slots or other games.

Check the playthrough requirement of each casino bonus before you make any decisions. This will tell you what multiple of the bonus credits you will need to wager to convert them into withdrawable cash. For example, a $100 bonus with a 10x wagering requirement means you would need to place $1,000 worth of bets.

Most slots count 100% toward completing the requirements, whereas table games may only count 10% or 20%. However, some slots such as high-RTP slots or progressive jackpots may not count at all, so check the terms and conditions carefully.

How to play online slots in 7 steps

The best online casinos make it simple for you to create an account and start playing slots. Just follow these steps:

  1. Choose one of the online slots sites we have recommended above. Follow the “play now” link or click the promo code to visit the site and claim the sign-up bonus.
  2. Fire up the slots site’s registration form and fill in your full name, date of birth, phone number, email address, home address and final four digits of your Social Security number. Choose a password. Make sure the promo code appears in the appropriate field.
  3. Accept the terms and submit the form. The casino will try to verify you. If it is unable to do so, or if it does not offer automatic verification, upload any additional documents that it requests to confirm your identity.
  4. Visit the online cashier and deposit money into your account. The site will then release the bonus credits if you have redeemed a deposit bonus.
  5. Select the “Slots” option on the homepage to browse the full library. Alternatively, head to a sub-category, such as Megaways or jackpot slots, or search for a specific game.
  6. Click on a game. You will see a paytable, which explains the payout rates for the various symbols, along with a description of the game.
  7. If you are happy, enter the game. Choose your bet amount and click to spin the reels. If certain matching symbols line up on one or more paylines, you will win, and your winnings will appear in your balance. Repeat as many times as you like, but remember to gamble responsibly.

Real money slotsFree slot games

Success is never guaranteed, and you can lose money when playing online slots, so please gamble responsibly.It can be frustrating to secure a win when playing in demo mode, as you will not earn a profit.

Legal online slot casinos are available in six states. Such casinos need a license from the gambling regulator in that state, such as the New Jersey Division of Gaming Enforcement or the Michigan Gaming Control Board.

Software providers must also obtain licenses in each state to supply online casinos with slots. The list of licensed providers varies on a state-by-state basis, which means that the same online casino may offer different slots in each state.

Types of online slot games

There are thousands of online slots at some casinos. They may be grouped into a variety of sub-categories, which can aid navigation. These are some of the key types of online slots:

High RTP and online slot payouts

Every online slot has a return-to-player rate. This tells you the theoretical return that an average player would receive. For example, if the RTP is 95.8%, the average player would get back $95.80 out of wagers totaling $100. All results are random, meaning certain players win and others lose, but selecting games with high RTP rates will theoretically improve your chances of success.

The random number generators that provide the results at each online slot adhere to the stated RTP rates. They receive independent testing for accuracy and fairness, ensuring that they uphold the RTP.

The chart below highlights the games with the highest RTP rates at legal online casinos in the United States. Some of them, such as Blood Suckers, offer a high RTP percentage to all players. Others, including Medusa Megaways, require you to activate the bonus buy feature to benefit from the top RTP rate.

How do I pick a good slot title?

Start out by identifying a range of high-quality slots from reputable providers such as NetEnt, IGT, SG Digital and Lightning Box at a licensed online casino. You can then focus on factors such as the RTP rate, theme, volatility level and features when selecting an ideal online slot for your personal preferences.

What are the most popular online slots?

Which slots have the highest RTP rates?

Blood Suckers, Starmania, Secrets of Atlantis and White Rabbit Megaways are among the online slots with the highest RTP rates.
