What does a slot machine consist of?

The slot machines included in the Wizardo casino catalog are characterized by many innovative features, but let's start with the basics. In addition to special symbols, these games are composed of common elements that are found in all types of slots, such as:

• Reels:these are the vertical cylinders that rotate with each spin. The most common configurations include 5 reels, but there are also more innovative schemes with variable or expanded reels.
• Game buttons:include the "+" and "–" buttons to adjust the bet, the start button for the reels and, in many slots, the Autoplay button to start multiple consecutive automatic spins.
• Paylines:they are the lines on which you get a win when the symbols align correctly. Some slots have fixed lines, others allow you to choose how many to activate, while modern "ways to win" slots offer thousands of possible combinations.
• Paytable (paytable): shows the value of the symbols and explains the winning combinations, essential to understanding the dynamics of the game.
• RTP (Return to Player): indicates the theoretical percentage of return to the player. It is an important data to assess how potentially favorable a slot is in the long run.
• Volatility: measures the frequency and amplitude of wins. Low volatility slots pay more often but less; those with high volatility offer higher prizes but less frequently.

The paytable in video slots

The slot machines that can be found online all provide players with a paytable, easily accessible via a dedicated button, usually called "Paytable" or "Help", visible on the display. The presence of the paytable is not at all random: it is a mandatory element by law, designed to offer transparency and clarity in the gaming session. It includes fundamental information, such as the number of active pay lines in the slot, the winning combinations and the direction of the winnings, i.e., the pay lines. Generally, the reading of lucky combinations starts from left to right, but in the most modern games there are certainly exceptions: some slots also have vertical, diagonal, zig-zag lines, or with even more innovative patterns.

Those who want to delve into how the slot works can therefore rely on the paytable for a complete overview of the rules and potential of the game. In addition to lines and traditional symbols, descriptions of special features, such as Wild symbols, Scatter symbols, and any bonuses, are always present. Moreover, the functioning of the jackpot is also specified, which can be either fixed or progressive, depending on the slot.

RTP in slot machines: what is it and why is it important?

The acronym RTP refers to Return to Player, which is the percentage of wagered bets that is returned to users who continue to play in the long term. The value of this return is calculated on thousands and thousands of slot spins, but does not reflect the actual specific return one gets from playing. In simpler terms, the RTP is based on an algorithm that allows the slot machine to dispense a sum of money every certain number of spins made, in order to grant the player wins that are high or low.

Obviously, it is a value that influences the choice of the slot to play with, but let's remember that these games, like many others in the casino category, are mainly based on luck. It can happen to play a slot with low RTP and receive a stroke of luck with a big win, or choose one with high RTP and lose the same sum wagered.

It is important to understand the difference between volatility and RTP, so as not to confuse the two terminologies and choose the wrong slot to play. Volatility is the value that indicates the average frequency of wins: a slot with low volatility generally has a high win rate but with smaller winnings. Conversely, a slot with high volatility grants fewer wins to the player but much larger amounts.

Top game slot bonuses: what are they?

Free slots and paid slots share the same game mechanics and offer all players numerous types of advantageous bonuses. These bonuses are designed to always ensure the best possible pay out, that is the percentage of money wagered that is returned over the course of the game. By doing so, the games are even more exciting and stimulating, and ensure a compelling gaming experience for all.

What are the bonuses of slot machines

Slot machines offer many varieties of slot bonuses to enhance the gaming experience. Among the most common are free spins, like those you can accumulate during special promotions or the welcome bonuses, which often double or triple the first deposit. There are also cashback bonuses or loyalty bonuses reserved for regular players that provide special benefits and exclusive offers.

Each online slot features its own bonuses, as well as its own Scatter and Wild symbols, for constantly renewed fun. Study the slot you are about to play carefully, so as to fully exploit its many winning possibilities. Bonuses consist of additional points, extra free spins, or various systems of prize multiplication, making the gaming experience even more exciting and advantageous.

How to use slot machine bonuses

Using slot machine bonuses is simple and can significantly increase your chances of winning. First of all, read the terms and conditions carefully to understand how to activate and use each bonus. Use free spins, like those offered during special promotions, to try new slots without risking your own money. Take advantage of welcome bonuses to increase your initial budget, use cashback bonuses to recover some of your losses, and keep an eye on loyalty bonuses to gain additional long-term benefits.

To be sure of taking advantage of bonuses that are actually active during your gaming session, it is advisable to visit the Promo page of Wizardo casino. This way you will also have the opportunity to redeem additional prizes available to you, often with an expiration and time limit to use them.

It starts by playing "For Fun", that is free and for fun, but when the prizes become real, the fun grows even more!

Slot Cash Collect: what they are and how to play them on Wizardo casino

Among the most innovative slots available at Wizardo casino are the Cash Collect, a series of titles by Playtech that combine the classic gaming experience with the mechanics of symbol collection featuring immediate prizes. The operation is simple: when the "Collect" symbol appears on the reels, all the cash values and bonuses on the screen are collected by the player, adding adrenaline and extra winning opportunities with every spin. At Wizardo casino, you can enjoy various versions of this type, such as Lucky Gift Cash Collect, featuring cascading modes and in-game jackpots, Football: Cash Collect, which brings the excitement of soccer to the reels with free spins and special prizes, or Atlantis Cash Collect, set in the mythical sunken kingdom and enriched by free spins and bonus games.

How to choose the slot

The catalog of online slot machines at Wizardo casino consistently enriches with novel proposals, always offering you the chance to try new games. Starting from the most recent categories, such as slots with jackpots, the most played, and finally the new bar slots section (which recreates the atmosphere of the most popular slots found in any bar), you can start selecting your favorite games. To make navigating through the myriad of slots available in this section of the portal easier, Wizardo casino provides you with practical filters, located on the left column, allowing you to freely select games characterized by features you desire. With a simple click, for example, you select all slots that include bonuses, free spins, cascading modes, twin reels, bidirectional winnings, or other mechanisms capable of making the game even more engaging. Thanks to the specific filter, instead, you can specify a precise range for the number of winning lines (ranging from 1 to as many as 10,000!), thus obtaining a selection of slot machines equipped with the features that interest you most.

For a fun and comprehensive gaming experience, choosing the right slot that matches your style and interests is the main step. If you don't want to spend too much time scrolling through the hundreds of slot machines in the Wizardo casino catalog, you can already get an idea based on the characteristics that many games in the same category share. Here is a first overview of the alternatives to classic slot machines:

• Megaways Slots: contain a greater number of symbols on the reels (from 2 to 7) that increase the chance of obtaining winning combinations with every spin. An example from this category is NetEnt’s Gonzo's Quest Megaways.
• Chicken Slots: one of the most popular categories and virtually a must in virtual casino catalogs. What sets them apart from others are the presence of 2 variants: the Play & Hold reels (double spins) and the rich henhouse bonus full of multipliers. Notable mentions are WMG's Fowl Play Gold, Skywind's Win the Hen, and Pragmatic Play's Chicken Drop.
• Book Slots: distinguished by the uniqueness of the symbols and the bonuses that award free spins. In this case, Wild and Scatter combine into a single symbol, the "sacred book," which before the free spins opens and chooses a symbol to expand on the reels during the bonus turn. The most widespread slot of this type is undoubtedly Greentube's timeless Book of Ra, and all the additional slots that are part of this saga.
• Cluster Pay Slots: these do not rely on paylines but rather on the number of connected symbols within a spin, often with a cascading mechanism as seen in Play'N GO's Reactoonz.

Apart from these categories of slots, another type includes jackpot slot machines. There are two different types of jackpots in these casino games: progressive or fixed. In the first case, they are won randomly when they appear on the reels of a spin, while the latter offer pre-determined prizes based on bet multipliers.

What does "jackpot" mean in slot machines?

In online slot machines, the term jackpot refers to the highest prize obtainable within the game. Slots with a progressive jackpot accumulate a portion of players' bets into a prize pool that grows over time until it is won, while slots with a fixed jackpot offer prizes of a predefined amount, determined based on betting multipliers. In addition to the potential for winnings, these slots also stand out for their special features, which make the gameplay even more dynamic. Among the most common are the Expanded Wild, which covers entire reels increasing the chances of winning combinations, the Respin, which allows repeating a spin to attempt new wins, the Doubling feature, which allows multiplying the amount obtained, and the Free Spins, which are free spins that often activate thanks to bonus or scatter symbols.

Choose from the top-rated online slots at Wizardo casino

Among other options based on which it is possible to filter the Wizardo casino online slot catalog, notable features include the availability of playing in mobile and/or VLT versions, the category of the theme (Adventure, Movies, Sports, Animals, Superheroes, History, Horror, etc.) and the name of the producer (Playtech, Netent, Big Time Gaming, etc.). Here are some of the most popular themes among online slots, which remain an evergreen at any time of the year:

Are movies and TV series among your passions? Wizardo casino also offers a selection of slots inspired by some iconic films or TV shows:

• Jumanji
• Rocky
• The Walking Dead
• The Gladiator
• Breaking Bad

These are just some of the reference titles for online slots on the platform that you will find in the catalog. During major holidays, you can also keep the festive spirit alive while playing by choosing slots with a Christmas or Easter theme, or settings of Halloween.

The most interesting parameter, however, is the one related to volatility that we have already mentioned: you can choose to display only slots that have a specific value, keeping in mind that lower volatility corresponds to more frequent but smaller winnings, while higher volatility results in less frequent but larger prizes. Moreover, the menu at the top of the section allows you to highlight only the latest slots added, those that also include an overall jackpot, or the "Most Played" ones, which are the favorites of Wizardo casino users.

Online slot machines: innovative features

The slot machines at Wizardo casino stand out not only for their engaging themes but also for the innovative features that enrich the gaming experience. Among these, we find:

• expanding reel slots that allow players to increase their chances of winning, offering a wide variety of winning combinations;
• "sticky" symbols that remain fixed for several spins, increasing the chances of activating paylines;

• dynamic or expanding Wilds, i.e., wild symbols that expand on the reel or move between reels (walking wilds), increasing winning combinations;
• the "Gamble" or double-up feature, which allows you to risk the win in a mini game, for example by guessing the color of a card, to try to double it;
• the "Hold and Win" mode, in which special symbols lock on the reels during respins, offering the chance to obtain extra prizes or jackpots by filling the screen.

Online slot machines: the main symbols

Each slot has unique characteristics and specific game modes, but there are some symbols that are consistently repeated in almost all video slots, which are essential for more fun and bigger wins.

Wild

Considered the most powerful symbol, the Wild acts as a joker, allowing any standard winning combination to be completed. There are two particularly interesting types of Wilds: the expanding Wilds, which extend vertically to cover the entire reel, and the Sticky Wilds, which remain fixed in position even in subsequent spins, thus increasing the chances of achieving a winning combination.

Scatter

The Scatter is often linked to Free Spins, one of the most appreciated features by slot players. The appearance of two or three Scatter symbols on the reels (depending on the specific rules of each game) activates a package of Free Spins, during which the player can spin without spending money, maintaining the active line bet from the spin that activated the Free Spins.

Bonus

This symbol activates the bonus game, a specific interactive mini-game for each slot, where the player must perform certain actions, such as choosing an object, to earn additional winnings.

Jackpot

It is a special prize that is put up for grabs and whose value is determined even before the game starts. Such a jackpot can be won when the "rare" winning combinations appear, often composed of bonus symbols, which are defined in the slot's rules.

These symbols not only influence the winning combinations but also introduce elements of surprise and interactivity that make the game more engaging for the player. Understanding how they work and how to best utilize them can make a difference in the ultimate success of the game.

The recent growth of the online slot sector

Over the last year, the trend of slots in Italy has shown a notable increase, thanks to the evolution of technology and the growing popularity of online platforms. Slot machines, both physical and virtual, have attracted more and more players, driven by the desire to experience new forms of entertainment and to try their luck. Digitalization has had a significant impact: online casinos offer a wide range of innovative games, featuring captivating graphics and engaging mechanics. Themed slots, inspired by movies, TV series, and pop culture, have captured the interest of a younger audience. Moreover, interactive features and special bonuses have made the gaming experience even more appealing. For this reason, Italian authorities have intensified efforts to ensure player safety, implementing stricter regulations and awareness campaigns. The challenge for the sector will therefore be to find a balance between innovation and consumer protection, promoting an increasingly safe and responsible gaming environment.

A crucial aspect of this safety is represented by the ADM license (Customs and Monopoly Agency), which ensures that gaming operators comply with strict safety and transparency standards. Only platforms with an ADM license, such as Wizardo casino, can operate legally in Italy, ensuring fair games, protection of player data, and the promotion of responsible gaming. ADM licensees are therefore required to use up-to-date technologies and are subject to checks to ensure users meet the reference standards to maintain the concession.

The experience of playing online slots

Today's slot machines are not the same as they used to be. Over time, they have transformed into increasingly engaging and well-crafted games, where entertainment is almost as important as the chance to win. Why? In addition to the classic dynamics of spinning reels, other elements come into play focused on capturing the player's attention and offering an immersive experience. Graphics play an important role, increasingly detailed and realistic, often accompanied by animations, captivating visual effects, and soundtracks specifically designed to create the right atmosphere. Many slots are built around a narrative theme: there's a story to follow, a context, and characters. This makes each spin something more than just a simple attempt to win. In some cases, the slots also include very enticing extra features, such as small goals to achieve, bonus modes, or missions that unlock thanks to special symbols.

Behind this more "playful" appearance, however, there is solid and rigorous technology that ensures randomness and fairness: the RNG system, acronym for Random Number Generator. This software integrated into the slot has the task of determining, in a totally random manner, the result of each spin. Practically, it decides which symbols will appear on the reels at each spin, independently from previous plays. It is thanks to this mechanism that each player has the same chances, without external influences or predictable patterns. In short, while slots have been enriched from a graphical and narrative point of view, on the other hand, they continue to rely on a precise mathematical system, which ensures fairness and transparency with every play.

From the origins to online slot machines

Slot machines, today an icon of the gambling world, have their roots in the late 19th century. The first mechanical slot machine, known as the Liberty Bell, was created in 1895 by the young Bavarian inventor Charles Fey, who had moved to the United States in search of new opportunities. The Liberty Bell had three rotating reels decorated with symbols of hearts, spades, diamonds, horseshoes, and, of course, the liberty bell, from which it derived its name. This simple machine became an immediate success thanks to its ease of use and the excitement it offered to players, who could win up to 50 cents if they lined up three Liberty Bells.

The operation of the Liberty Bell was entirely mechanical: the reels were spun by pulling a side lever, which triggered a spring mechanism. When the reels stopped, a combination of symbols determined the outcome of the game. Although this mechanism was rudimentary by today's standards, it laid the foundation for modern slot machines. In the following years, the success of the Liberty Bell inspired many other inventors and manufacturers to create their versions of gaming machines, introducing variants with different symbols and cash prizes. However, it was only in the 1960s that the first major technological innovation occurred with the introduction of electromechanical slot machines, which combined electrical components with the traditional mechanism, making the game more reliable and safe.

The technological evolution of slot machines

With the advent of microprocessors in the 1970s, slot machines became fully electronic. These new machines allowed the implementation of more complex and varied functions, such as introducing multiple paylines and bonus games. However, the most significant leap occurred with the advent of the Internet and digital technologies, which led to the creation of online slot machines. Today, these virtual machines are accessible anywhere and at any time, offering an immersive and interactive gaming experience, with advanced graphics, engaging animations, and a myriad of different themes. From the simple lever of the Liberty Bell to the click of a button on a mobile device, the basic principle of the slot machine – the anxious wait for the reels to stop to reveal the result – has remained unchanged. However, technology has transformed a mechanical game into one of the most popular and sophisticated forms of entertainment in the modern world.

At Wizardo casino, you have access to a rich array of attractive, colorful online slot machines full of surprises and special prizes. You can choose to play for free, without any real wager, or try your luck to win cash prizes.
