Interviews
Q&A – Quality control w/ Yordan Petkov, Product Owner at Silverback Gaming
Online slot developers make a lot of noise about the quality of their games and how crucial it is to the player experience they deliver. Given the sheer quantity of slots in the market, quality can be a real differentiator so it’s vital that developers get this right.
But quality assurance is no easy task and requires planning and a seamless process capable of detecting any issues within a game.
Once issues have been detected, the studio must have mechanisms in place to resolve them effectively and efficiently so that development remains on schedule while ensuring the game is actually ready for release.
To learn more about how studios approach quality assurance, we spoke to Yordan Petkov, Product Owner at Silverback Gaming.
How do studios ensure quality across game design, audio, play, etc?
The commitment to quality must cover all areas of game development, from design to build to delivery. The foundation of quality is the early detection of issues and ultimately this requires meticulous planning. By spotting issues early, they can be ironed out in the most efficient and cost-effective way and that’s why at Silverback we focus on anticipating potential problems from the outset. This proactive approach helps to mitigate risks and lays the groundwork for smooth and seamless game development and deployment.
Can you share more insight into how Silverback approaches quality assurance?
We have mapped out a step-by-step approach that encompasses everything from concept and design through to final execution. Each aspect of game creation, including graphics, audio, math, mechanics, game engine as well as front end, is done with careful consideration and planning. By establishing robust processes and incorporating thorough checks, our teams can concentrate on refining and enhancing the game experience instead of firefighting preventable issues and this is what allows us to take the player experience to the next level.
What does the testing phase actually look like at Silverback Gaming?
Our testing is structured and spans multiple stages.
Stage one is the pre-development phase. During this part of the process, the QA teams ensure all required information is provided and they also scrutinise game specifications. This is a super important point in the process as anticipating issues and addressing them at the concept stage is more effective than having them crop up later on.
Stage two is proof of concept. The first build of a game marks the second stage of testing and the QA team rigorously examines critical aspects of the slot, such as engine performance, functionality, stability and of course regulatory compliance. This phase ensures the core components of the game are sound before we move on to the next stage of development and testing.
The final testing stage focuses on the audio and visual elements. Here, we delve into the finer details and make sure the game aligns with best practices and upholds the standards of quality that we have built the Silverback Gaming name on.
How does quality carry over into the delivery of games, which can be an issue for both studios and their operator partners.
In terms of delivering games to operators, this comes down to having a cutting-edge remote game server that can handle integrations into the different platforms that operators are running on. There’s always the chance of encountering issues with integration and that’s why it’s important to have a dedicated team for this. In terms of the quality of the games that then land in the operator’s lobby, the studio must have put the necessary steps and processes in place to ensure these have been identified and address long before integration. Nobody likes to play a buggy game and a studio ultimately lives and dies on the experience its slots provide to players.
Are there any common issues that occur when developing slots?
Yes, but part of quality assurance is ensuring that issues are not recurring. When an issue occurs, it’s important to approach it in a way that addresses it there and then, but also prevents it from occurring again in the future. This is key to making quality assurance as effective and efficient as it can be – if not, you are simply wasting valuable resources on fixing problems that you are already aware of and have addressed in the past.
What sets apart your approach to QA and how do you ensure nothing slips through the net?
Our approach to QA is underpinned by our quality-focused culture which we apply to everything we do. Having top talent in every team ensures that each part of the game has unrivalled expertise working on it. Additionally, we have open communication across all design and development phases, which is pivotal to the overall quality of our slots. Collaborative discussions help iron out potential pitfalls and provide valuable insights that contribute to the highest quality end product.
What are the upsides to investing in quality assurance and making it a top priority?
QA teams not only identify bugs but also contribute to the overall quality of the game. Their valuable suggestions and insights lead to continued improvement. While having the right processes in place for testing is important, experience often reveals unforeseen issues and that’s why having a talented and experienced QA team is crucial. Our influence spans all stages of game production, minimising the risk of potential problems and ensuring that when issues do arise, they are quickly resolved.
QA-driven quality results in polished, engaging games that players love. In turn, operators appreciate the reliability and appeal of the games, allowing the studio to build a long and successful relationship with the casino. At Silverback, our product owners are fully committed to fostering collaboration and translating vision into reality while upholding a customer-centric approach. This shapes games that resonate deeply with players and operators alike.
By building a culture of quality, anticipating potential pitfalls and executing a well-structured testing process, we ensure that our games deliver exceptional player experiences. Quality is not just about finding defects; it’s about delivering excellence and making lasting connections with players and operators.
For those that might not know, can you give us a brief overview of Pick’Em Player Props?
In simple terms, the new Pick’Em Player Props product from WA.Technology is almost like a hybrid between fantasy sports and sports betting. In the same vein as traditional player props products that you see in traditional sports, players can select markets on individual players – we have just taken that model and elevated it.
During the game, players can make between two and six bet selections. For example, will Erling Haaland score more or less than 2.5 shots? The number of bet selections the player makes then determines their multiplier. By allowing bettors to unleash their sporting knowledge and provide engaging games for them to play, we are helping our operator partners to not only engage with a wider player base but also to fuel long-term retention. It really is a one-of-a-kind product and one we’re incredibly excited about. It’s already proving to be a top performer in LatAm.
Why has now been the right time to unveil Pick’Em Player Props?
Over the last few years, we’ve seen significant growth in the number of player proposition products. There are several reasons for that. Sports fans have shown a growing affinity for individual players rather than a team. They follow players on social media and engage with content featuring that player.
This reflects the wider trend we’re seeing: the new generation of fans is more in love with the players than the team itself. A great example of this is both Lionel Messi and Cristiano Ronaldo. Bettors worldwide would wager on either of those players and engage with their content regardless of which team they played for or what club they supported.
The appetite for player-driven betting is increasing dramatically, resulting in a greater demand for products specifically tailored to individual athletes.
With more traditional sportsbooks, however, we’ve found that there isn’t as much depth of product regarding player propositions – aside from goal scorer markets. We wanted to change that – we wanted to deliver a fun, engaging product that helps build a sense of community among players.
Since Pick’Em Player Props is also a hybrid of fantasy and sports, it can act as an attractive tool to facilitate new market entries, as fantasy sports are not regulated like sportsbooks or iGaming. Take the US for example. In most states, operators do not need a licence to offer a fantasy sports product. This is the case for many markets around the world, too. I believe this will be an attractive proposition for operators looking to expand their international footprint, and as a truly global provider, we’re here to make that happen.
In your view, what differentiates WA.Technology’s Pick’Em Player Props from other player props products on the market?
Currently, we are the only B2B provider to offer a player propositions product that combines sports and fantasy. A handful of companies in the US offer something similar, but they are all B2C companies – we are bringing something totally unique to the B2B space.
Fantasy Sports have always been popular in the US. But over the last 18 months, we’ve seen a meteoric rise in the demand for player proposition markets; we wanted to develop a product that caters to that growth in demand and delivers something unique for our partners.
For other player props products on the market, something that is worth noting is that the design and UX are doing little to engage Millennial/Gen Z bettors. This audience demands a streamlined UX that is easy to use. Our Pick’Em version has been specifically designed with this demographic in mind, although we have been careful not to disenfranchise other age groups. We have kept the design sleek, streamlined and easy to use to deliver that. It’s extremely well-designed compared to what you might see in a more traditional sportsbook.
The game is straightforward to understand because we have fixed multipliers. This decision differentiates us from more traditional products, where the multipliers vary depending on how many bets you place. It also makes the product much more accessible for players who might otherwise not be familiar with fantasy or player props.
Another major defining factor is that we have ensured players can add multiple bets from different markets together. On most sports betting sites out there, you cannot combine player props markets. You couldn’t, for example, have a bet slip combining Erling Haaland’s Over/Under Shots and Kevin De Bruyne’s Shots on Target. We know this is frustrating for many bettors. We wanted to eliminate that barrier and elevate sports fans’ experience.
How does the level of data granularity influence the design and effectiveness of player proposition betting products, particularly in terms of player engagement and personalised betting options?
We are very fortunate that the data feed we use for our player props markets is the best. We have a wide range of insights and data analytics available, giving us an edge over other companies within the space – this is a serious differentiator.
The enhanced data range means we can deliver many more bespoke, personalised betting options to players while also getting more granular with the markets we can offer.
Our Managed Services Team, which oversees all things trading, also closely monitors the markets that are most popular with players. For example, if we see an influx in bets on ‘shots on target’, we know how to create more promotions around this particular market. We can tailor the CMS to engage better with players and create a more personalised experience.
Players can also ‘favourite’ particular players and clubs. Any market featuring that player will automatically appear when the Pick’Em Player Props application loads up.
Are there any markets where you believe Pick’Em Player Props will prove to be particularly popular? If so, why?
In all honesty, I can’t think of a market where this won’t be popular! Regions such as LatAm present an enormous opportunity for the growth of player proposition markets. I believe we can really plug a gap in the products currently offered to bettors.
Across the continent, we’ve seen players show a real passion for player-focused markets, and we’re here to capitalise on that. In Brazil, for example, if we were to create markets on Neymar, I’d anticipate this would gain much traction!
The real selling point for Pick’Em Player Props here is that we offer an extensive range of sports and markets that cater to a broad audience – but within that, we can personalise sports and bet selections not to overwhelm the player. I’d expect that markets on football will perform exceptionally well across Africa and LatAm, while countries such as South Africa may have a stronger preference for Rugby or Cricket.
Ultimately, it’s about understanding the unique preferences of players within each jurisdiction our partners operate in and tailoring the product accordingly. With teams based in various markets worldwide, we can get to grips with the local knowledge and fully understand what resonates with bettors.
In your view, what are some of the factors behind the growth of player props products in the last 12 months?
Most definitely shows how sports media companies are incorporating more player-specific content into their roster. This already has a huge impact, and I can’t see it changing anytime soon.
Whether it’s interviews with specific players, post-match analytics on performance or even the inherent growth of social media, the balance is undoubtedly tipping more towards the player rather than the team.
Personalisation will also have a considerable knock-on effect on the growth of player propositions. Bettors want more bespoke offers, specific bet suggestions and more instant content tailored to their unique playing habits. With a product like Pick’Em Player Props, you can personalise that betting experience to your heart’s content.
It also becomes much easier for sportsbooks to align with a specific user’s interests when we deliver unmatched data analytics and levels of personalisation that are available via WA.Technology’s product suite.
In short, Pick’Em Player Props gives operators the tools they need to create wide-ranging engagement opportunities without sticking to the rigid sporting calendar, where sometimes you might have to wait several days between a game. By incorporating fantasy sports, we can deliver round-the-clock content much faster, therefore meeting the demands of players. If you want to find out more – make sure to stop by Stand 1095 at SiGMA!
Behind every stellar online slot is an equally stellar maths model. These are becoming more experimental as the industry flirts with an increasing array of innovative new mechanics. We spoke to Pablo Martinez, Math/Design Lead and Founder at maverick game studio Peter & Sons to find out more.
Do you have to be a maths genius to build a slot machine?
Nah, you don’t need to be a maths genius. It’s more about having the right mix of skills and loving what you do. You need to play a lot of games, see what’s working out there, and understand what makes them fun. Knowing maths helps, sure, but it’s more about creating something players want to keep coming back to.
Peter & Sons is known for making games that dare to be different, visually and thematically. Is the underlying math equally experimental?
Definitely! We love pushing boundaries, both in how our games look and how they play. Sure, it’s a bit of a gamble to have a bunch of games with unique mechanics, but we’re all about trying new things. Games like Peter Hunter and our upcoming Muddy Waters are great examples — they bring fresh gameplay and new experiences to the table. Each year, we try to put out at least one or two experimental titles, keeping things interesting while mixing them with more familiar styles.
Do you come up with the maths model first and then build the game around that? Take us through the process of building the game from start to finish.
We usually start with an idea for the mechanics first. We make a quick prototype to see if the concept can work with the maths. Then we bring in the art team to brainstorm themes that will fit well. Once we have a basic prototype, we go through a bunch of tweaks and changes until the art, mechanics, and maths all feel right together. It’s a back-and-forth process where we’re constantly finetuning everything to get the best balance.
Why do you think a mechanic like Megaways was so successful?
Megaways took off because it’s a fun, exciting mechanic that gave players something fresh, but smart brand marketing really helped it catch on.
Is there pressure as a slots developer to come up with the ‘next’ Megaways?
Not really. Coming up with new mechanics is always fun, but it’s not the only way to make a hit. Plenty of top games are just clever twists on classic mechanics. It’s more about creating a great experience that keeps players coming back, whether it’s something brand new or just a fresh spin on something more familiar.
Which slots are more popular, high or low volatility, and why do you think that is?
It depends on the market, but in some unregulated markets — and especially with some operators — high-volatility slots are really popular. A big reason for this is streamers. High-volatility games make for exciting content, so they get a lot of attention and hype online. That thrill factor really draws players in.
Which is your favorite Peter & Sons mechanic and why?
Right now, I’d say the fishing mechanic in our upcoming game Muddy Waters. It’s a new twist on the fishing genre that really brings something fresh to the gameplay. It’s exciting to take a familiar theme and make it feel totally different.
Tell us about the mechanics in your latest release, Barbarossa Revenge.
Barbarossa Revenge is a pirate-themed, high-volatility game with 243 ways to win. It’s a DoubleMax game, meaning the multiplier doubles with each cascade. You’ve also got Multiplier Jumps and a Cashout feature that guarantees wins. During Free Spins, the multipliers don’t reset and can keep growing unlimited. With a max win potential of 30,000x the bet, this game is a real thrill!
We’re only a few months away until the highly-anticipated Brazilian market launches, and it’s safe to say that the industry is on the edge of its seat waiting to see what lies ahead for the South American sleeping giant. But one company that is poised and ready to capitalise on the golden opportunities this market has to offer is Infingame.
Gabriel Pinto, Sales Manager at Infingame, outlines some of the recent developments taking place across Brazil as he discusses how Infingame is catering to the unique demands of players across the market.
Brazil’s regulated market is expected to officially launch on 1 January 2025. Now that we’re only a few months away, what are your overall expectations for the Brazilian gambling market once it is fully regulated? Where will the biggest opportunities be?
I think it’s an excellent move. For a start, the launch of Brazil’s regulated markets means that operators, suppliers and affiliates will be dedicated to protecting players under licensed market conditions. That includes fair play, responsible gaming and security – both in terms of transactions and technology. This, I believe, will help build consumer trust and participation in the market.
The regulation of the gaming sector in Brazil is also going to have hugely positive effects on job creation across Brazil. As we all know, this is an industry which has operated for quite some time – but the new legislation will help formalise various different sectors, including technology, customer service, marketing, commercial sales and much more.
Sportsbook, of course, is going to be massive, but I think many have overlooked just how exciting iGaming can be. So much of the retail-based heritage when it comes slots especially, is part of our culture already and has been for so many years. IGaming is really going to be the one to watch and given we’re one of the fastest-growing aggregation hubs in LatAm, we can’t wait to begin entertaining players in the regulated market.
Data has suggested that players in Brazil tend to prefer higher volatility verticals, such as slots. What motivates players to choose these games over others?
I think it all comes down to culture and history. We have a history of land-based gaming here in Brazil – for more than 100 years, we’ve had games in the street, card rooms, bingo, land-based machines. This is a sector which has become deeply ingrained in our culture.
As a result, I think slots have an air of familiarity among players. Players are aware of what slots involve, the various different games available to them, who the big-name developers are. I think that it is this affinity with the vertical that makes slots much more popular than other types of gambling products.
Players also understand that slots are a great form of entertainment – playing habits suggest that bettors across Brazil prefer low-stake, high volatility products, which reflect the fun nature of gaming when it comes to betting small and win big. They also create a sense of excitement that more traditional games might not manage.
Slots, in particular Fortune Tiger by PG Soft, have been incredibly popular with players. It really is a truly loved game here, and the title has become the go-to for many bettors – which isn’t necessarily the case in other markets around the world.
How do levels of engagement with high volatility games such as slots differ to that of live casino or table games?
Live casino is hugely popular with bettors across Brazil too! Over the last few years in particular, this vertical has absolutely boomed – and the reason for that is familiarity.
Slots have typically out-performed more traditional table games, but live casino is most certainly experiencing signifcant growth. The live casino suppliers that can effectively tailor their games to the local market – from featuring local, Brazilian croupiers to incorporating culturally-significant icons and designs – will reap the rewards of Brazil’s regulation.
At Infingame, we have a broad portfolio of games that have all been handpicked – our in-depth knowledge of each market means that we know each of the games on our platform will resonate with local players. We have spent a lot of time getting to know players, understanding what they like and what they don’t, what verticals perform well, the game designs that players enjoy – and everything else that comes with it.
With this in mind, are there specific game mechanics or themes that resonate more with Brazilian players? If so, why?
Anything with a local twist! We’ve seen a particular up-tick in football-themed casino games – this was a trend that was certainly prominent throughout the 2022 World Cup and the Copa America this year.
As a result, we’ve noticed that many operators are looking to include Brazilian themes within their slot offering, with many incorporating games that feature samba, football and local icons into their games. Of course, that makes perfect sense.
Another trend that we’ve noticed is that many operators are requesting exclusive, branded content to roll out to their players. They want slot titles and casino games that are developed specifically for their brand – be it joint ventures with game developers, or partnerships with local icons such as sports clubs.
I think that this is a trend that will continue long into 2025, as casinos look to make their mark on the local audience. Not only is it a great way to get your name out there, but it is also a much more cost-effective way to create a unique experience for your player base. Gambling is very much a commoditised industry; there is very little differentiation in the actual products and bonuses out there. Of course, exclusive games help to disrupt that status quo and bring something new to the table. This will definitely be an area to watch.
How do Brazilian players’ session lengths and frequency compare to those in other markets?
Players tend to gamble for longer periods of time, but with lower stakes. They see casino products as a form of entertainment, with many players usually enjoying the occasional bet during an evening or when they have a spare 30 minutes.
However, we should note that this trend differs depending on which device players are using. Those using mobile tend to enjoy shorter playing sessions, showing a preference for more high volatility games such as crash games and slots, while those on desktop tend to enjoy sessions ranging from 1-2 hours.
Those on desktop show similarities to land-based bettors – they tend to gamble in the evening, products tend to include more table games and traditional casino products, although similar to mobile, the stake tends to be lower.
How important is mobile gameplay in Brazil, and how does it impact player engagement and retention? How can brands best optimise their games to better suit mobile-first gaming?
It’s not just important, it’s critical! Everyone has a mobile device, and for many, this is the go-to platform in which to enjoy casino games. To not optimise your games to mobile devices would risk alienating a large portion of your player base.
In Brazil, there has been significant improvement in mobile connectivity and smartphone penetration, meaning that more players are able to access games via their handheld devices. But in order to create the most optimised experience, casinos and game developers must adapt their UI to suit mobile devices. Another consideration is developing games that are tailored to single-handed play – with many players enjoying casino products on the go, ensuring that your games cater to playing habits is essential.
Based on current player habits and preferences, what future trends do you expect to emerge in the Brazilian casino market, particularly in online slots?
As we’ve covered already, and I can’t re-enforce this enough, localised content that is tailor-made to the Brazilian market is going to be key. This will by far be one of the biggest trends. As operators flood into Brazil, there will be fierce competition among brands looking to amass market share and engage with new players – so the key to achieving that will be through providing content that they cannot get anywhere else.
I also think we will see slots and live casino continue to grow in popularity. Their high volatility and social nature will no doubt drive loyalty among players and keep them engaged in the long-term. And I think the final trend will be that we will see verticals such as crash games emerge as a front-runner among bettors – these products are simple to understand and highly engaging, a perfect recipe for players looking for entertainment!
