Best Casino Slots with the highest RTP Payout

6.   Slots of Vegas Casino

This is not a Las Vegas hotel & casino where you would need to look at booking hotels before playing your favorite games. This is an excellent online casino experience with a high RTP so you don't have to worry about low casino payouts either. It even has a $4000 welcome bonus on offer to get newcomers up and running without putting up too much of their own cash.

Book of 99 (New)

RTP: 99%

Reels: 5

Pay Lines: 10

Free Spins: Yes

Bonus Rounds: Yes

Fun to Play Score: 10 out of 10

As the name of the game itself suggests, Book of 99 is a great slot game by Relax Gaming, and it comes with an RTP rate of a whopping 99%, which is mesmerizing. Its grid contains 5 reels and 3 rows, and this slot also has a high volatility rate. There are a total of 10 fixed paylines.

Book of 99 features a Wild Book symbol, but unlike most slots where the Wild substitutes regular symbols, it is also the key to Free Spins in this game. By landing at least 3, Wilds Books will reward players with 10 Free Spins. Additionally, for every Wild that is landed, the meter fills up by one, and players receive Free Spins when the meter reaches 99. Bets in Book of 99 vary between $/£0.10 and $/£100. I love this slot machine game, with the record high RTP of 99%! and a bonus round similar to the one on the famous Book of Dead online slot, Book of 99 will surely be a player’s favourite.

A high RTP 

One of the best ways to compare online slots is by looking at its Return to Player (RTP) percentage. This value describes the amount the game pays back to players over a larger number of spins, and it’s often expressed as a percentage. Most online slots available in US casinos boast an RTP ranging from 92% to 98%.

For example, an online slot that’s advertised with a 96% RTP will theoretically give $96 for every $100 wagered in the game. The general rule is that a higher RTP for slots is good for the player is it pays more. The best online slots payout percentage will create a better overall experience for the players.

I call BS! - Why I Believe Slot Machine Games are Not Random

Slots are not random, and I will never be convinced otherwise; I have been playing slots for many years and seen so many examples of them being NOT random, making it incredibly difficult to believe that slot machines are random, here's why:

• If slot machine games are designed to fit into a math model, which they are said to be, then they cannot be TRULY unpredictable.
• I have played certain online slot machines where the "Payout" or money won amount is displayed BEFORE the bonus game spins end.
• How is it possible for a slot machine to be a random device and for a machine to also have to pay back a certain percentage of the money played through it?
• Anyone who's played certain slot machines, for example, could not fail to notice how you don't see ANY certain symbols on the reels for ages, then suddenly they are everywhere!
• It often feels like some algorithm is at play, preventing a certain feature from happening too soon after starting a slot game and only happening once you've lost enough money to cover the feature's payout.
• Have you ever been steadily winning playing a certain amount, e.g., $1, so you decide to bet more to win more and increase your bet per spin to $2. What happens? The machine "instantly" stops paying and becomes deader than a Dodo bird! Strange, isn't it, considering slots are supposed to be so-called "random" (sarcasm).

On some progressive jackpots linked to a bank of slot machines, the jackpot has to be won before a certain amount of money is reached. Now, if this is the case, how are they REALLY random if they have to hit before the jackpot reaches a certain amount? Completely random means they can hit at ANY time. They must be programmed to do that if they have to hit by a certain amount.

I was once asked in an "anonymous" online casino survey, "If I felt like I received enough playing time for the amount of money fed to the slot machine!" Why ask something like that if it is beyond their control to "adjust the settings"? Was it because if a player were losing their money too quickly - resulting in a shorter machine play time - the machine would "compensate" by paying out more before the end of the playing time? This time of play adjustment would then allow casino patrons, both on and offline, to "feel" they had value for money due to the adjusted extension of playing time on the machine.

Good Girl Bad Girl

We all have an angel on one shoulder and a devil on the other. Betsoft knows this, and it incorporates the idea in this terrific 3D game, where an angel character floats on one side of the screen, and the devil one on the other.

However, it is not its visual beauty, complete with 3D models, that make this 2014 slot stand out. It is its RTP of 97.79% and progressive jackpot within its Money Wheel Bonus feature that makes it one of the best paying online slot games.

The Most Popular Video Slots

Video slots are the main category of games you will find today. They are an absolute blast to experience and worth your while. These games are the backbone of any casino, and they run in the hundreds. New players usually head for these gems as soon as they pick up their welcome bonus. Now, it’s true that there is some overlap in the terms. Put this way; a video slot can have both classic slot and 3D slot elements incorporated in its visuals or gameplay.

It may even have a fixed jackpot. Take Pragmatic Play’s Wolf Gold, for example. It’s a video slot, but it still offers jackpots. But let’s just give a brief and reliable definition of video slots. These online games are the main type of slot you can play today.

They feature many exciting features, such as wild, scatter, and bonus features. You can benefit from free spins, bonus games, and other particular features developed for each individual game exclusively. Video slots offer you 100% towards your wagering requirements, making them one of the best games you can enjoy at an online casino.

NetEnt has one of the largest collections of such games, with hundreds of games just waiting for you to try them. Yet, there are many more awesome games you can play today. Some of our favourites include Book of Dead by Play’n Go, Gonzo’s Quest by NetEnt, Thunderstruck II by Microgaming, or Book of Ra by Novomatic.

These slots aren’t nearly all. And how could they be when there are close to 20,000 online slot games you can try these days? Video slots are awesome for another reason, too. They have a flexible bet limit. You can bet between €0.10 per single spin all the way up to €125.

None of these betting limits is set in stone, of course. Some slots might ask for a little more – as in €0.20 and then keep the maximum bet no greater than €20. This usually depends on the particular game. You will generally notice that if a game offers a huge multiplier, as in 5,000x your bet, the maximum bet will be lower.

SLOT TIP 8: LOOK FOR NEAR MISSES

Scouting near misses means looking for games with jackpot symbols on the reels or screen, but just short of a winning combination.If you’re in the right frame of mind, the scouting can add a little intrigue to choosing a game, but near misses aren’t really any indication of what’s to come.Near misses give no indication of future outcomes.So it goes with slot systems. They can add a little interest to the games, but they can’t change your outcomes or lead you to a winning machine.

3. JAMMIN’ JARS – 20,000X THE BET

This is one of the favourite games of the team here at SlotsHawk. Jammin’ Jars is a brilliant online slot which comes with a win potential of 20,000x your stake.

With free spins, respins, multipliers and sticky wild symbols, there is no shortage for excitement. The theme is a classic fruity but with so many features, Jammin’ Jars is the best fruity we have ever played!

• Free spins
• Bonus game
• Wild symbols

Our Top 10 Tips for Playing Online Slots

A skilled gambler understands that betting entails more than just laying down big sums of money. We’ve put together a list of 10 simple tips to assist you in mastering the slots and winning big money.

1. Find Out How to Get More Payouts on a Regular BasisThe greatest approach to ensure you have a better chance of winning a progressive jackpot is to play a game with a lower payout. These are the games that are most likely to pay off.
2. Take Care of Your MoneyMake sure you know how much you want to spend playing and how much you can afford to spend before you start.
3. Bonus Rounds Should Be Looked forBonus rounds are essential if you want to win jackpots and get free spins, and they’re also a wonderful way to maximize your winnings. 
4. Consider the PaylinesYou’ll know your odds of winning if you know how many paylines your selected game has. Take the time to learn about the paylines in each game before you begin.
5. Choose Trustworthy CasinosThis is something we can’t emphasize enough! There’s no use in winning if you can’t get your money out. Check that the casino you want to play at is licensed by a reputable organization.
6. Take Your TimeWe understand how simple it is to become hooked on the thrills of fast-paced online slots, but you must resist! Consider your every action, especially in the bonus game.
7. Participate in the ClubMany online casinos feature slots clubs, which are designed specifically for slot players. If you join one, you’ll be eligible for additional benefits such as cashback, special deals, and other freebies.
8. Make a Note of Any Bonus Codes or Special OffersAlmost all online casinos provide bonuses to both existing and new players. Bonus codes and other promotions like free spins and no deposit bonuses will be used to provide these benefits.
9. Simpler Games to PlayTypically, the more complicated a game is, the more time and money the developer has put into it. As a result, they’ll want to collect more from players before making large payments. You may discover that your odds of winning will improve if you stick to simple classic games.
10. Discover Large Progressive JackpotsWhile games with lower progressive jackpots pay out more regularly, if you’re chasing big cash, there’s just one way to go. Look for games that have large progressive jackpots!

The gaming industry is big business in the U.S., contributing an estimated US$240 billion to the economy each year, while generating $38 billion in tax revenues and supporting 17 million jobs.

What people may not realize is that slot machines, video poker machines and other electronic gaming devices make up the bulk of all that economic activity. At casinos in Iowa and South Dakota, for example, such devices have contributed up to 89 percent of annual gaming revenue.

Spinning-reel slots in particular are profit juggernauts for most casinos, outperforming table games like blackjack, video poker machines and other forms of gambling.

What about slot machines makes them such reliable money makers? In part, it has something to do with casinos’ ability to hide their true price from even the savviest of gamblers.

6: Buffalo King – 93,750x

There’s obviously something about 4,096 paylines that can deliver the biggest wins. This one’s from Pragmatic Play and they’ve turbocharged a familiar bonus feature.

Land 3 Bonus symbols to trigger 8 Free Spins. Nothing special there. But land 6 Bonus symbols and you get 100 Free Spins! If that wasn’t enough, there are Wild multipliers of up to 5x during Free Spins, and you can even retrigger up to 100 extra Free Spins. Bonkers. That Free Spins x Multiplier combo is a feature that recurs a lot in this list, and it’s like rocket fuel for max wins.

Are these the best William Hill Slots or the best Betfred Slots?

The answer depends on what you consider as “the best”.

If you are looking for high RTP slots then yes these are the best you can play at these online casinos or any of the casinos we are listing on our site.

However, If you are looking for modern, top notch graphics etc then you might want to have a look at the newest slot games that these casinos have added to their collection.

5. Scroll of the Dead

Scroll of the Dead is an Egyptian-themed 5x3 slot that has a 94.28% RTP with high variance. Its gameplay is straightforward where you have the usual Wild symbol and Scarab Scatter symbol. When you trigger the free spins mode with three or more Scarab Scatter symbols, you open the door to high payouts.

During the free-spins mode, a 6th reel is opened and the reels turn into a 6x3 structure. With the addition of the sixth reel, you can match six symbols that have better payouts. In addition, Scroll of the Dead randomly selects one symbol upon trigging the free-spins mode. This symbol will have an expansion function, allowing it to fill a column when it lands on any reel. By combining the expansive symbol-function and sixth reel, you have the potential for incredible slot machine payouts.

You will find games with different pay lines, enjoy different storylines, play games with low, medium, and high variance, and naturally a different RTP with each title.

There are some baselines, of course, and the most commonly apply to the same type of games across several pre-selected types of online slots. We want to draw your attention to the most popular types of online slot games and see what makes them worth playing in the first place.
