Where to Find the Best Online Slot Games 2020

In the ever-changing world of online casino gaming, it is not always easy in 2020 to find the best online slot games, new slot games are being brought to the market every day. It is possible to find slot titles named after many of the latest movies, TV game shows and even famous rock bands. Competition to deliver the best online slot games to avid players is also growing more intense. Top games producers such as Microgaming, NetEnt and Yggdrasil are having to compete against newer players such as Tom Horn, Red Tiger and Fantasma Gaming.

Ultimately, this means that the bar is being pushed ever higher in terms of quality. Graphically, many of today’s best online slot games have an almost ‘Disneyesque’ feel about them. Indeed slot players are now able to play games based on Marvel and DC characters such as Wolverine or The Dark Knight Rises. Together with bigger and bolder bonus options and much better RTP than their land-based equivalent, the overall slot playing experience is currently at an unimaginable level.

Ken’s Slot Club is committed to bringing you the best online slot games from the world’s biggest games producers, and steering you in the right direction as to where to play them.

Online Slot Games are so Much Fun

Slot machines have been around now for well over a century. Ever since 1887 in fact, when the Liberty Bell slot machine (the original one-armed bandit), was invented by an American named Charles Fey. Featuring just three reels and five symbols: a Liberty Bell (hence the name) along with a horseshoe, a heart, a diamond, and a spade it was a relatively simple device. Fast forward 130 years or so and the mind-blowing selection of online video slots available for you and I to play would leave Charles Fey speechless.

This is What Your Great Great Grandmother Played – Liberty Bell Slot Machine

Today’s best online slot games have incredible graphical detail, together with video and audio technology that Charles Fey could only dream about. The technology that modern slot game manufacturers have at their disposal make it possible to create a total sensory experience. Something that Charles Fey never could.

This is the key to the popularity of modern online video slots. All of the original elements are still there. The spinning reels, the heightened risk and of course the opportunity to win bundles of cash at the best online slot games. Only now game providers have added fully immersive gameplay, storytelling and pulsating soundtracks into the mix.

Online Slot Game Reviews

Who doesn’t love to play the very best online slot games packed with amazing features and super-high jackpots? We know you do! That’s why Ken Slots delights in sourcing great slot games for you to try. The site is updated regularly with the best online slot games bought to you by the best casinos in the land. When we find ’em we review ’em, and this is what we look for…

  • Playability. The best online slot games have to be fun, they also need to be easy to learn.
  • Graphics. Best online slot games not only have to play good, but they also have to look.
  • Features. What good is a slot game without plenty of free spins and wilds?
  • Longevity. Will they pass the test of time or are they just a flash in the proverbial pan?
  • Coin-in Coin-out. Volatility isn’t the most important factor in the best online slot games, but it helps.

Understanding Slot Volatility

If you enjoy playing the best online slot games there are a few things that you should know. One of the most important of these is the volatility of any given slot game. What is volatility I hear you ask? Well, simply put, the volatility of a slot game (alternately referred to as variance) refers to the frequency in which the best online slot games can reasonably be expected to payout. Games with low volatility pay out much more frequently than those with high volatility.

Essentially there are 3 basic volatility types…

Low Volatility Slots Produce Consistent Returns

Slot games with low volatility generally tend to produce more frequent wins, though for smaller amounts. They can be recognised by the lower variance between the minimum and maximum win amounts.

Lower Volatility Slots

  • Less variance between min/max win amounts
  • Lower payouts but far more often
  • Much lower risk to the player

Medium Volatility Slots – More Features Better Potential

As you may have guessed, medium volatility slot games fall somewhere in the middle in terms of variance. Players on medium volatility slots will experience plenty of features and good returns with the possibility to capture quite significant jackpots. These type of slot games tend to be the most popular amongst regular slot players for precisely these reasons.

Medium Volatility Slots

  • Mid-range variance in min/max win amounts
  • Payout reasonable amounts fairly frequently
  • Lots of feature games
  • Potential for sizeable jackpot payouts

High Volatility Slots For Those With More Time on Their Hands

Slot games with high volatility will often have a greater variance between the minimum and maximum bets. These slots tend to pay out infrequently, but will payout larger amounts. High volatility slot games come with a higher degree of risk.

High Volatility Slots

  • A greater variance between min/max win amounts
  • Payouts are less frequent
  • Higher paying jackpot games
  • Players of these slots take on more risk

Determining the Volatility of a Slot Game

Before playing any slot game try to acquaint yourself with the pay table (look for the information icon in the bottom right corner). From here you should be able to gauge the difference between some of the payouts on any given line. For example, try looking at the difference in payout between 4 and 5 symbols on a single line. If the difference in the amount of the payout is low (3-5x) then this is a low variance slot. Should the difference be in the 5-10x range then this would be a medium variance slot. Once you start getting in the 10-15x difference in payout size then that will surely be a high variance slot game.

The big jackpot games are nearly always high volatility. This is because slot manufacturers are not going to make it easy for you to win the mega moolah. If you are going to be chasing after the sky high jackpots then you need to have patience.

Another reliable way of determining a slot game’s volatility is by actually playing it. You can play any of the best online slot games below for free (demo mode) before committing your cash. If you are getting frequent returns then you are playing a low volatility slot game.

To determine the volatility of a slot game…

  • Study the paytable carefully before play
  • High paying jackpots generally mean high volatility slots
  • Similarly, a high maximum bet is usually a good indication of high volatility
  • Play all the best online slot games in demo mode before committing funds

Adjust Your Gameplan to Account For Slot Volatility

It isn’t possible to say with any degree of accuracy what the definite volatility of a slot game is. This information the game manufacturers keep to themselves. However, they do make public what sort of gameplay you as a player might expect from one of their games. Volatility can be a good guide as to the sort of experience you will have playing any given slot game but it is not an accurate determiner of success.

What sort of experience you are looking to get from playing the best online slot games is up to you. If chasing down a massive jackpot is your thing, then be prepared to sit it out for long periods just feeding the machine. To win a 6 or 7 figure jackpot, it is likely that you will need a large enough bankroll and be capable of playing at high enough limits to make this happen.

Conversely, if you are happier playing at more affordable limits and appreciate more consistent returns, then a low to medium volatility game is going to be better for you. You need to know your limits.

Return to Player – 3 Little Words That Mean So Much

RTP is one of those terms that is frequently misunderstood by online slot players. Return to player is the percentage of ‘the drop’ (money played at any given machine) that should theoretically be returned to the players as winnings over time. The keyword here is ‘theoretically’. The average RTP for an online video slot is around 95-97%. Which means that for every €100 deposited in the machine (we will call them machines even though they are in fact online) €0.95-0.97 should be returned back to the players in payouts, Unfortunately, this does not mean that if YOU play €100 in a machine you will end up losing only €3-5.

Best online slot games have no memory (cognitive memory not Random Access Memory!) They are incapable of doling out money on a case by case basis. Over time they will pay out the advertised RTP, but that period of time is over the lifetime of the machine not during the time that you spend playing. It is for this reason that you will experience both highs and lows when playing online slots.

How Random is a Random Number Generator

A random number generator or RNG is the software that effectively dictates how the best online slot games that you are playing behave. Each game that you play online will have a unique RNG. Its purpose is to spit out code in a totally random way that the machine then interprets in order to dictate the result. For example, the winning number at roulette or symbols on a slot machine’s win line.

There are basically two types of RNG, a hardware random number generator and a pseudorandom number generator. A PRNG is what we are concerned with, as these are what power the best online slot games. Each game manufacturer will have its own base code that they use to power their games. This code is a complicated algorithm that determines the outcomes of a spin.

This algorithm is continuously calculating the next result. It does this by processing billions of numbers every millisecond. By pressing the start button on your desktop or mobile a sequence is activated and the RNG does its thing. It is important to note that the combination of symbols that will appear on your screen is already predetermined even before the reels have been launched.

Best Online Slots Games 2020
Each spin of the reels is part of a 3 step process with you, the player, as the trigger.

RNG’s Process Unbelievable Amounts of Data

These algorithms process unbelievable amounts of data at incredible speed. The numbers that are formulated to determine the outcome once you hit the start button are made up of thousands of digits. As an example, the infinite number π (which has a sequence of more than 5 trillion digits) is commonly used. Further calculations using standard mathematical functions such as addition, multiplication, division, subtraction and rounding, etc are also required. Therefore we can clearly see that for an RNG to process a sequence of numbers and use that sequence to determine an outcome with any kind of consistency is virtually impossible.

The Importance of the Seed Number

OK, so this is going to get rather technical now. So technical in fact that I am not sure that I understand it myself. Essentially for any RNG’s algorithm to output a series of random numbers, it must first be triggered by an un-random number. This number is known as the seed number. Or as Wikipedia puts it…

A random seed is a number used to initialize a pseudorandom number generator. For a seed to be used in a pseudorandom number generator, it does not need to be random.

It is the existence of this ‘seed’ number that leads some slot players to believe in conspiracy theories surrounding the randomness of the best online slot games that they play. If the seed number could be discovered then it is possible, technically, to manipulate the outcome. However, there are a couple of flaws in this argument.

The first is that the manufacturers do not have a vested interest in doing this. There are literally hundreds of security protocols in place designed to safeguard the seed number. Secondly, the casinos themselves could gain no tangible benefit from manipulating the results as they are audited every month. Thirdly, and most importantly the casinos already have an edge that they openly disclose. They don’t actually need another.

RNG Casino Certification

Casinos licensed by a recognised gaming jurisdiction are required by law to have their RNG certified. Licensing authorities check the certification of every online casino. There are 3 principal testing agencies around the world. They are…

  • eCOGRA which is located in London, UK
  • iTech Labs – Melbourne, Australia
  • Gaming Laboratories International (GLI) – New Jersey, USA

Certification by any one of these approved independent laboratories is your guarantee of protection. You will find their logo listed at the foot of the casino homepage. All online casinos listed on Ken’s Slot Club possess an RNG certificate.

Testing of RNG’s is not just a ‘one-time’ thing. The process of running verification tests is ongoing, using data taken from the casino game servers. The testing agency will run regular audits approximately once per month. These same agencies or laboratories also test the best online slot games RTP for accuracy. This rigorous testing process helps to ensure customer confidence. Testing laboratories will seek to verify the following criteria…

  • Statistical randomness
  • The internal state of the RNG
  • Seeding, re-seeding and cycling
  • Unpredictability and non-repeatability
  • Usage of random numbers including scaling and shuffling
