Online Slots Guide: How We Review Online Slots

The world of online slots is massive, and new games are launched every week… So much so that it’s increasingly difficult to make a selection and decide what games are worth a try. Is there really such a thing as a “bad” game? Essentially, yes, although casinos are filled with all sorts of slot machines – some of them developed by lacklustre and lazy game studios – our goal here isn’t to analyze the entire industry but rather to share the qualities we study to establish a list of premium quality slots.


Casino operators and game developers have their lethal weapon to hook slot machine players: a permanent catalogue of anti-routine news. Winnings alone are no longer enough for online gamblers, especially for younger generations. You need sexier and slicker slots that pull the player in and allow him to enjoy an immersive experience. To boost the attractiveness of their slots, casino game studios spend considerable amounts of time and money on developing concepts that will appeal to generations of gamblers who are used to a constant stream of innovation. Although an import feature, the innovative aspect of any slot isn’t the first thing that players look for, one could wage that the rapid developments in online capacities and the growth of increasingly powerful devices will allow for the birth of groundbreaking online slots to take place. Artificial intelligence and virtual reality combined with 5G will pave the way to levels of casino gaming yet to be experienced in the world of casinos.

Fun Factor

Fun should always be your number one priority when playing casino games. Certainly, money and the potential to earn staggering sums or even jaw-dropping jackpots is part of the deal. But it should be viewed as a “possibility” and not the ultimate aim of the game. This is why top slot studios such as Microgaming and Net Ent hire teams of talented and innovative game creators to design slots that appeal to the senses and are entertaining and sometimes require a bit of intelligence and the ability to strategize.


Creativity is an important factor in term slot quality and increasingly appears as a factor for online gamers when choosing which slot to play. With today’s technology and fast internet connections, slot creators try to outperform each other to deliver games that are fun and innovative but also beautiful.


A slot’s success is usually measurable by its longevity. Titles that we see appear in the most popular lists of online casinos comprise such names. They often answer to a series of criteria: great user experience, attractive design, good bonus features, fun gameplay, and an uncanny way to appear personable… In other words, online slots that age well have character. Often, we can just tell what games are equipped for a long ride. This is the case with Immortal Romance, Jurassic Park, and Mega Moolah. At times, game providers realize that a game is on a roll but needs a bit of a redesign and thus release an updated game. This was the case with the much-loved Slot Father Part 2 by Betsoft. As you’ve probably guessed, a second version is always a dead giveaway in terms of longevity.

Variance x Volatility

The word “variance” is used more often in poker, but it is also sometimes heard in the world of slots. Volatility, on the contrary, is a term often found in the world of finance. In this industry, it’s a term employed as a statistical measure of the change in the price of a stock on the stock market. Basically, volatility and variance slot machine are essentially the same thing. Slot machines are all linked to a volatility index, which indicates how volatile the game is. Traditionally, this was not really information that game software developers liked to make public. But with the growing interest in online gambling and the ability to share information across the web, everyone is doing it nowadays. The volatility index is calculated by the sum of all possible combinations, winning or losing, which indicates the chances of winning and how much.


The term playability is often used to summarize the crucial aspects of a slot game. It refers to anything under the player’s control and explains the pleasure experienced while playing the game. From this simplified definition, several aspects of the gameplay can be clarified. The first, “gameplay,” refers to the range of actions offered to the player in the game interface. The greater is the number of options, the greater their combination can be. The playability of a game is not just about how you play the game itself but also about the overall feel, which has everything to do with the visual and musical qualities of the game. Today, slot sound effects, designed with care and attention to match onscreen graphics, are just as important as the overall experience.


The capability of the free online slots casinos is also a highly essential factor to consider. Free online slots casinos that have massive potential usually have more customers. This is because all players want a higher chance of winning slot games. So they will always choose online casinos with massive win potential over those with low win potentials. Slot games that have high wins are usually more volatile than those with low win potential. You need to check out the capability of the casino by considering its volatility and maximum win potential. You should check out how many slot games it features, which ones are free online slots, and which ones are not free. This will help you determine the quality and efficiency of the casino you want to play your games.

Know The Difference Between Low vs. High Volatile Slots

When playing an online slot machine, one of the things that will influence your winnings or losses will be the game’s volatility. Should we favour a volatile slot or not, and how to choose?

Understanding volatility

First and foremost, it is important to define volatility in the context of a slot. In this kind of casino game, volatility is the extent of variation in winnings. The more volatile a slot is, the less often players could enjoy prizes, BUT they also provide higher rewards, as this is where the big jackpots are won. Conversely, the less volatile a machine, the more regular but less important the gains will be. The principle of volatility is close to the concept of variance. Players who bet for the thrill of the game will often prefer volatile slots. Those who want to bet with a more regular return on investment will choose low volatilities. Therefore, it is up to you to choose the type of games you prefer according to your gaming priorities.

Low Volatile Slots

Low volatility slots allow you to play longer sessions without winning big, but without losing too much money either. Players keep enjoying small wins, which encourages them to keep playing. It is ideal for players who fulfill their contract with online casinos, welcome bonus wagering requirements, and other reload bonuses. Low volatility slots include Immortal Romance, Megadeth, Rage to Riches, and South Park.

High Volatile Slots

Slot machines with high volatility are the ones that provide the most adrenaline and excitement in online casino games. This type of volatility allows play to play dozens of times without winning anything. A word of advice: keep playing if a big win is your priority. What are great high volatility slot titles? To name a few, highly volatile slots include Gonzo’s Quest, Merlin’s Millions, Creature From the Black Lagoon, Mega Moolah, 300 Shields, and Dead or Alive.
