Why Slot Machine Development Is Quite Challenging?

The first slot machine was invented in the far year 1894. They are still fun to play, though — now in digital. According to Technavio's Slot Machine Market Industry Analysis, this fast-growing market is set to skyrocket by $8.91 Billion by 2025! This article will review what modern slot game development looks like and what you need to build a slot game.  

Learn Key Elements of Slot Machine Development

Any game design process can be divided into steps from coming up with an idea to post-production. How does slot development differ from the development of other games? Let’s review the details. 

Slot Machine Art

First, digital artists create concept art — sketches of the future slot game. The process typically looks something like this:

• Concepts inspired by other artworks, slot games, genres, movies, books, or any other inspiring things.

• Primitive sketches.

• “Middle version” or a basic artwork.

• 3D mockup or a 3D model with lighting and perspective (if it’s a 3D slot game). 

• Final render. 

Because slot machines have very simple mechanics in real-time casinos and digital versions of the game, the distinguishing feature of a slot game are often its art and story behind it. 

People create slot machines with fantasy, steampunk, sci-fi art, and use fandoms — movies, TV shows, games — gamblers know and love to attract a new audience (the latter requires IPs, though.) That’s why slot machines based on stories and concepts from the ancient Greek and Roman mythologies are so popular in Europe and the USA: for many, they have instantly recognizable characters and narratives. 

Mechanic

 

Mechanics describe how your slot game interacts with a gamer — and how a gamer can interact with it. 

Every game uses behavior people are prone to at some point (that’s why people love achievement hunting so much), and slots mechanics aren’t different. Casino slots are intended for a specific target audience – gamblers. They want to escape the real world — as most other gamers do — and they’re often super competitive. 

Slot machines often employ impressions of near-win to keep gamblers on edge: it’s never a failure, it’s just not enough of a win. The slot game interacts with users, encouraging them not to give up and rewarding them for it (with bonuses, boosts, and boons). 

Interestingly (and dangerously, if used maliciously), if in other games mechanics reward players for remembering the patterns and learning how to master the game, slot machines reward players for continuing to play. 

In a feedback loop, where only gambler, slot rows, figures of money won/lost, and a tiny menu exist — a user-friendly interface like this, devoid of distractions or references to anything other than slots is a feature of almost any slot machine. A gamblers’ brain, at some point, gives up on searching for patterns, because there are none due to randomization, and gives into a simple virtual world where all that matters is the process of trying to get lucky. 

Software

The next component of slot machine development is choosing the game engine/framework you’ll use to create a future game. 

Are you interested in how to make a slot machine game in Unity? We’ll explore this further — but keep in mind that Unity and Unreal Engine are needed mostly for innovative slots development. Flying cars from slot games, if you will. 

Building slots is simple in comparison to multilevel plot-rich titles — so companies often use web platforms to build them. Web constructors typically offer libraries with learning materials that guide people through the development; coding knowledge is useful, but frequently what’s needed is basics. This option is perfect for beginners in slots development. 

Languages

Once you choose the platforms that your game will run on, you must look for game engines that support the languages of that platform.

• Web games. HTML5 and JavaScript.

• Mobile games. Java, Kotlin, and Swift. 

• Desktop games. C#, C++, Java, and Lua.

• Console games. C++ only. 

So, your game engine of choice must either offer development in that language or an option to port to the language of the platform. For instance, Unity uses C#, but there are options to port C# to Android and iOS — tools that “translate” the game for a device under the hood. 

Cross-platform game engines like Unity, UE, Cocos2d, GameMaker Studio 2, etc. offer the opportunity to ship to multiple platforms at once which is why they’re often used by slot games developers. 

Engines

Game engines or frameworks are your slot software development tools intended specifically for game designing. 

High-end desktop slot games are often built using Unity or Unreal Engine software solutions — they’re very popular among gamedev as a whole, too. For mobile games, you may prefer Corona and Fusion. Phaser and Construct 3 do the work for web-based slots.

Stages of the Slot Game Development Process Explained

Now, let’s get into more details of the process and focus on what to do to make your game and your brand recognizable. 

Brainstorming Ideas

This stage is perhaps, the most straightforward and creativity-demanding one. Currently, there are thousands of slots. You need to make up something innovative enough to stand out from the crowd. 

Additionally, you need to brainstorm a design idea, i.e., what is the concept of a game itself. This will define the style of your game. Look for inspiration in history, popular art, themes of books, films, technologies, nature, animals, etc. 

Because slot games are designed to be infinitely replayed, there’s often no opportunity to sustain a coherent plot. But, stories can emerge everywhere — in the character's dialogue with the player, encouragement, on “timing-out breaks”, and so on. That can be a distinguishing feature of your slot game. 

Creating a Prototype

This integral step suits the only goal – find out if your idea performs well. For this purpose, you take your basic artworks, use software or a web platform to make a game layout work or MVP, and see if people enjoy it as you’ve thought they would. 

The prototype shows how the game functions. It often includes the music in the background, betting scripts, Random Number Generators (RNG), and the payment gateway if you’re building a slot game that people will pay for with real money. 

Coding

It is the main production stage: you’re creating the code of the game — through the game engine’s graphic user interface (GUI) or without it. 

This stage is usually divided into several phases of development, where each cycle ends with a previously established milestone. 

One of the most important game backend component is the math engine, wielding the power of a Random Number Generator (RNG) to shape the outcomes of every thrilling spin. For example our slot game developers meticulously fine-tunes the RNG and expertly crafts other crucial elements, such as:

• Win frequency.
• Win size.
• Volatility.
• Frequency of bonus prizes. 

As a result, you receive a completely functioning game for one or several platforms. It should be prepared for further integration with various payment systems. 

Testing

Testing is incorporated in development — each development phase is finished after testers and QAs validate a part of a game that has been developed. There are several pre-release testing stages like vertical slice and beta testing — when the slot game is presented to users for them to evaluate if it’s good and if they would pay money for it.  

Players provide developers with feedback, and they react to the reviews that have the most significance and the highest priority before release. 

Ensuring your slot game's appeal to players and maximizing its potential for success involves a crucial phase of meticulous polishing. The game testing process comprises four key stages: Unit Testing, System Testing, Integration Testing, and User Acceptance Testing. Each stage contributes to the overall refinement and seamless functionality of your game, ultimately creating a desirable and engaging experience for players.

After a game is polished – it is released one more time as a final version. Then – only the regular updates are to improve the game. 

Release and Maintenance

It is the end stage of slot machine game development. After months of coding, weeks of testing, and several prior releases – a game is ready to be sold to customers. 

Typically, a slot game does not have in-app purchases or any other features attributed to the regular gaming market. But, the constant maintenance is still due. Developers gather gamblers’ feedback and release updates, curate new events, run giveaways, and so on. 

Technical Challenges in Slot Machine Development

Slot machine development presents a myriad of technical challenges that demand careful consideration. A crucial aspects are:

• Implementation of robust random number generation algorithms, ensuring that outcomes are genuinely unpredictable and not susceptible to manipulation.
• Devising payout mechanics that strike the right balance between enticing players and maintaining the game's profitability is no small feat. Achieving fairness in gameplay is paramount, demanding rigorous testing and calibration to prevent biases or unfair advantages.
• Fortifying the game's security against potential threats like cheating and hacking attempts, safeguarding player data and ensuring a trustworthy gaming environment.
• Developing captivating visual and auditory elements to create an immersive gaming experience requires adept integration of multimedia technologies.

All these technical intricacies collectively demand a highly skilled and knowledgeable team capable of navigating the intricate landscape of slot machine development with finesse and precision.

Player Psychology and Game Mechanics

Crafting a successful experience transcends mere random chance and delves deep into the realm of player psychology and intricate game mechanics. A remarkable slot game is one that thoroughly comprehends the players' psyche and ingeniously incorporates elements to captivate their attention. Key factors such as payout ratios, thoughtfully integrated bonus features, and captivating visual feedback all play pivotal roles in influencing player engagement and fostering long-term retention.

This multifaceted endeavor entails striking a fine balance between visual allure and performance optimization to deliver a captivating user experience.

Implementing flexible and adaptive design principles becomes imperative to ensure that the game adapts flawlessly to varying screen sizes and resolutions. Additionally, developers must grapple with unique input methods, such as touch controls, which necessitate intuitive user interfaces. By leveraging cutting-edge technologies and responsive frameworks, game developers can unlock the true potential of cross-platform slot machines, captivating players and securing a coveted position in the competitive mobile gaming landscape.

Data Analytics and Player Insights

The quest for excellence surpasses mere game creation, as data analytics emerges as the cornerstone to continuously elevate the player experience. Armed with a sophisticated arsenal of analytical tools, slot game developer delve into the intricacies of player behavior, unearthing invaluable insights that drive informed decision-making. By meticulously dissecting player interactions and engagement patterns, casino game developers gain a deep understanding of preferences, pain points, and desires, all while identifying opportunities for enhancement.

Moreover, actively seeking player feedback through various channels allows for the cultivation of a symbiotic relationship, fostering a community-driven development approach.

Summary

As you are fully aware now, the slot development process is complex and simple at the same time. As with most games, slots, too, require creative work and a deep understanding of the player's psychology, even though the mechanics they employ frequently build upon convention and multiply it rather than invent something new. (By the way, you can invent something new. That’s a large market opportunity.)  

Note, that safe gambling practices need you to install mechanisms for players to take breaks and impose limits on the amount of time they spend playing. It’s best to do that even if your game doesn't ask them for real money.
