Whilst many people decide which slot to play based on the theme, special features or promotional offers, the savvy gamblers steer towards slots with the highest RTP. The house edge of online slot machines can vary widely, and it stands to reason that the lower the house edge, the better your chances of winning.
Top RTP Slots | RTP | Bet Limits | Free Spins | Paylines | Rows | Reels |
---|---|---|---|---|---|---|
Jack Hammer 2 | 97.10% | £0.50 – £250 | 10-20 | 99 | 3 | 15 |
Simsalabim | 97.50% | £0.25 – £125 | Yes | 25 | 3 | 5 |
Retro Reels Extreme Heat | 97.50% | £0.30 – £112.50 | Up to 20 | 30 | 3 | 5 |
Devil’s Delight | 97.60% | £0.20 – £40 | Yes | 20 | 3 | 5 |
Kings of Chicago | 97.80% | £0.05 – £50 | Up to 30 | 5 | 3 | 5 |
Starmania | 97.87% | £0.10 – £20 | 10 | 10 | 3 | 5 |
Blood Suckers | 98.00% | £0.25 – £50 | 10 | 25 | 3 | 5 |
1429 Uncharted Seas | 98.60% | £0.10 – £100 | 25 | 50 | 3 | 5 |
Jackpot 6000 | 95.10 – 98.90% | £1 – £2 | No | 5 | 3 | 3 |
Mega Joker | 99% | £1 – £5 | No | 5 | 3 | 3 |
Your odds of winning are better than this, as you can hit five bells, five whistles or five of any other set of symbols, so on this machine your odds of any set of five are actually 5 x 0.032%, or 0.16%. So once in every 625 spins of this hypothetical machine, you’ll hit your set of five identical symbols for the jackpot. Originally, casinos installed slot machines as a diversion for casual gamers. Unlike traditional table games (such as blackjack or craps), slot machines don't require any gambling knowledge, and anyone can get in the game with a very small bet. This idea proved to be a monstrous success - slot machines.
Of course, you should keep in mind that only the best slot sites to win offer high payout games from which you can take advantage. The return to player percentage of a game is measured over thousands of game rounds, and it stands to reason that the higher the RTP, the better the deal for the player.

#2 Jackpot 6000 (NetEnt) – Up to 98.8% RTP
Jackpot 6000 is a thrilling classic slot machine from NetEnt with a real old-school vibe. You can play with up to 5 paylines active, betting between 1 and 10 coins per spin. It is highly recommended to play with the maximum bet of 10 coins however, as this creates the possibility of triggering Supermeter mode. In this game mode, you can win a mystery prize of between 10 – 6000 coins when just 2 joker symbols land anywhere on the reels. Also, getting 3 jokers on a payline in Supermeter mode guarantees a jackpot payout of 6000 coins. When you play Jackpot 6000 with 1 – 8 coins, the RTP is a paltry 74.9% – 79.2%. Yet with 10 coins in play, the RTP ranges from 95.1% – 98.8%. The variance is because Supermeter mode is skill based, so you can directly impact the outcome.
#1 Mega Joker (NetEnt) – Up to 99% RTP
Whilst Jackpot 6000 boasts an extremely high RTP, it is just beaten to the top spot by another NetEnt classic slot; Mega Joker. Bet with just 1 coin and the RTP is an underwhelming 76.9%. Yet on the other hand, a max bet of 10 coins elevates the RTP to between 89.1% – 99%. Furthermore, it provides bigger payouts and the Supermeter mode. In Supermeter mode, you need to choose the bet level and the optimum level at which to collect your winnings. It is this element of skill which can increase the RTP. The skill component, retro style and engaging gameplay make Mega Joker a firm favourite with players.

View all postsSlots has been a thing for eons. Over the decades, it has simply evolved and changed in form. But at its core, the gambling basics have remained unchanged. In the past decade or two, the industry has experienced many ‘tech upgrades’ that have increased the number of punters in the world. Today, you don’t have to take a trip down to Las Vegas. All you need is a steady internet connection an online casino you trust and you are set.Speaking of casinos, (land-based or online), there are two types of slot machines they feature; Class III and Class II. The two slots machines operate differently. The Class II slot machines are common in slots parlors. They are attached to Native American Casinos or horse racing tracks. Owing to improved tech tools, Class II slot machines have become more sophisticated. So much so that casual punters have a hard time telling them apart from Class III slot machines.
But you are in luck. In this piece, we shall scrape off the confusion by explaining the basics and answering some common questions related to Class II slot machines.
So, let’s get to it.
What Exactly Are Class II Slot Machines?
It’s simple. The Class II slot machines are designed to replicate Class III slot machines while remaining within the confines of the regulatory guidelines. The Class system is clearly stated and defined in the Indian Gaming Regulatory Act by the Federal Government. The Act defines all Class II games as bingo regardless of whether computer, electronic or any other tech gadgets are used with it and if it is played in the same room with bingo or any games similar to bingo.
The immediate consequence of this regulatory Act was that the high stake bingo games were legalized. Yes, the bingo games held in halls were super popular at some point. But with time, as developers sought to upgrade their gaming experience, they leaned towards a casino-like environment and experience. Though they managed to incorporate Class III casinos in some of their gaming options, they were met with a lot of resistance and legal issues.
It was during this time that Class II slot machines were designed. Since their inception, key players in the industry have been working around the clock to replicate Class III machine experience in Class II jurisdictions. Engineers have been contracted to build in-house systems while slot manufacturers were brought on board to create games that would run on the designed systems
How do they Work?
It’s true, aside from the LED bingo card which displays your card patterns for every spin; it’s really hard to differentiate the Class II from the Class III. The big part of the difference lies in how the game operates. So let’s peep under the hood and see how Class II slots machines are designed to meet legal requirements of being a bingo game.
First, there is usually a 20-millisecond window. Any person that presses the ‘Play’ button during this window enters into a common draw. For this draw to run there needs to be a minimum of two players (there is no maximum number). If there are only two players, one of them will get the winning pattern.
So here’s what happens when a video or slot poker is brought into the picture. Designers extrapolate odds of specific bingo games to video or slot games’ results that have similar odds. Usually, there are extra algorithmic processes that are in play which help to determine the outcomes but usually, the end results are similar – you pull the machine handle and the reels spin.
From the moment you pull the handle to the millisecond before they stop, you become one of the participants in a multiplayer bingo game. The results of the bingo game are ‘reported’ by the reels when they halt. If you are lucky, you’ll win some cash. So now if you think about it, you’ll have had a Las Vegas slot machine experience while in the background, the machine meets all the requirements which make it legal in Class II slot machine jurisdictions – areas where bingo is legal but RNG machines are not.
Now, most casinos that run the Class II slot machines claim that their odds are similar to those of Class III machines. This is how they explain it – it’s more like a scratch-off lottery card. But instead of scratching you’ll be pulling a handle.
And though this analogy is close to the real thing, it’s not quite accurate.
What do Class II Slots Look Like?
While they look extremely similar to Class III machines, the main way in determining if it is a Class II machine is to look on the display for a bingo table. It will look quite obvious and will indicate that the machine is using bingo logic rather than the typical RNG of a Class III machine.
Here’s an example below – notice that there is a bingo table located at the bottom right of the display.
Should You Play Class II Slot Games?
This is a really good question. And believe it or not, it’s pretty common. But despite this, its answer is not straight forward. But here’s something that will help you make that decision.
Gambling experts insist that Class II games are similar to lottery scratch tickets than Class II machines. You see, with lottery scratch tickets, the prize is determined before the printing of the tickets. Class II games may have shorter realization times but unfortunately, they aren’t random. The moment you pull the slot handle, the outcome of whether you have won or not and what prize you have won has already been made. The reels are only there to deliver the news.
Why do Casinos Prefer Class II Slot Machines?
Why is it that modern casinos seem to have a mix of Class II and Class III slot machines and games? And why is it that even with the mix, they are skewed towards class II games?
Well, first, the IGRA granted casinos self-regulating powers when it came to Class II games. However, with Class III games, they must be officially undergo rigorous testing through third parties and approved goverment organizations. This is to ensure that the randomness and reliability of the machine is deemed fair.
Second, casinos don’t have to pay taxes on the revenues generated from the Class II games. But on the Class III games, they are obligated to pay taxes.
Thirdly, the odds on winning in a Class II game are worse because you are put against a large pool of players to win instead of relying on RNG.
There you have it. Everything you need to make an informed decision. Hopefully, after reading this Class II and Class III slot machines don’t confuse you anymore. So with that go have a ‘happily ever after’ gambling experience.
