Who We Are
SlotsCalendar is an iGaming affiliate platform founded in 2018. It specializes in listing tens of thousands of free-version slots, casino reviews, bonuses, and other informational content on online gambling.
The brand is under the ownership of GSH Online Media, a group that operates several affiliate platforms across iGaming. SlotsCalendar is one of the company’s flagship products, and the primary one focusing on online casino gaming.
Where You’ll Find SlotsCalendar
The platform you’re currently on, SlotsCalendar.com, is our international version, available to all markets that have no specific locale-driven version.
We recognize the need for jurisdiction-specific analysis that requires advanced adaptation to account for local legislation, player behavior, and even cultural norms.
By providing a bespoke website for each of our current sub-brands, we ensure that we speak directly to the player and their specific wants and needs.
On a forward-thinking note, we also recognize the emergence and importance of numerous markets. SlotsCalendar aims to expand its horizons as we continue to amass more knowledge, observe more trends, and understand you, our audience, to an even deeper degree.
SlotsCalendar US
SlotsCalendar’s US-driven version is the American-facing platform we created to meet the needs of American players seeking information about their home markets.
Our dedicated platform aggregates and showcases offers and casino bonuses (among other services) exclusively from casinos licensed to operate in states where such products are permitted.
As such, you’ll only find brands licensed by the New Jersey Division of Gaming Enforcement, the Michigan Gaming Control Board, the Pennsylvania Gaming Control Board, or any regulator from markets that may open due to changing legislation.
SlotsCalendar UK
Things are slightly more straightforward with our bespoke UK-facing SlotsCalendar. This version lists online casinos, free slots, and other gambling products that are specifically sanctioned by the United Kingdom’s Gambling Commission.
Given the British regulator’s stringent requirements, the conditions are very demanding for operators seeking to operate in the UK market.
These sky-high standards align with our own desire to see you, the user, safe when gambling at online casinos. As such, you’ll only find casinos, games, and bonuses that operate with a UKGC license.
SlotsCalendar Brazil
Recognizing Brazil’s appetite for digital gambling products and the need for clarity and player education, we decided to launch a version dedicated to this market: SlotsCalendar Brazil.
A noteworthy aspect of this sub-brand is that it’s one of our non-English language platforms. Brazilian players can easily access a wide range of casino gaming products, guidance, and other valuable content in their native Brazilian Portuguese!
SlotsCalendar Canada
Our team joined the effort by launching and operating SlotsCalendar Canada – a place where Canadians can understand how operators try to garner their attention.
Canada is another outstanding market that has seen a significant rise in interest in online gambling, garnering legislative attention from the provinces.
As such, the emergence of province-backed administrative bodies such as iGaming Ontario and Alberta iGaming Corporation has made it clear that a comprehensive approach is essential.
We’ve studied the market through both formal and informal channels to ensure we understand its variety and requirements. For this exact reason, we believe that our work on this platform can be exceedingly valuable.
SlotsCalendar Romania
The Romanian version of the SlotsCalendar platform is the sub-brand that explores and lists all new products and developments in Romania’s iGaming space.
Given that the country has well-defined legislation, its own regulatory body, and numerous operational requirements, this platform is how the SlotsCalendar team seeks to uncover the market's inner workings.
SlotsCalendar New Zealand
New Zealand’s distinctive player base preferences and the burgeoning regulatory system have attracted our attention to the point where setting a SlotsCalendar NZ version became a natural choice.
It allows Kiwi users to browse options that are specifically marketed or exclusive to them, creating a curated experience that quickens their time for finding the right casino and offer.
SlotsCalendar in Spanish
This specialized variation of our website sets up the platform in Spanish as SlotsCalendar ES and is directly configured and curated for the Latin American markets, except for Brazil, which we’ve already mentioned.
These markets share Spanish as their primary language, so our platform assists players in this language. User sensibilities and market highlights apply specifically to these GEOs.
SlotsCalendar in Russian
SlotsCalendar RU aims to provide a helpful space for CIS states where Russian is either the vernacular or one of the official languages. All content and website features use Cyrillic script for this version of our platform.
How SlotsCalendar Started
You’ve definitely heard, used, or relied on information aggregators throughout your internet experience. We’ve done it too. We’ve always enjoyed the ability to hop on IMDb, Wikipedia, Fandom, and many other similar platforms.
We’re also gambling enthusiasts. And when we realized that the gambling industry lacked such a platform to store so much information, we decided to take matters into our own hands. Such was the birth of the SlotsCalendar idea, which is why we consider it the IMDb of Slots.
However, we also needed a concept to make it worth the effort of traversing so much information. Here’s how we thought things out:
The Calendar
We came up with the Calendar. You can track the newest occurrences in online gambling by checking the Calendar to see what’s new or upcoming. You can also receive notifications about every newly launched game and keep up with the industry’s main events.
If the idea was to provide endless information, we needed to give users the tools to access all that data. We understood that new slots launch every day, that casinos open and close consistently, and that various players have different needs.
As this idea took shape, so did the surrounding platform. We had an idea and a plan, and we decided to enrich this structure with features that benefit you, the player.
What We Publish
We decided that naming the games was far from enough. Our objective was to provide a complete experience that goes beyond plain information.
SlotsCalendar provides you with over 35,000 free-to-play slot versions. You can test them out, enjoy them, and learn all about them. However, we thought that our experience as both players and online gambling specialists could be put to good use. This was when we decided to create slot reviews as well.
We strive to paint a complete picture for as many games as possible. We imagined that understanding a slot’s features and knowing how to actually play can be of great service to any player. Moreover, we add between 100 and 300 slots monthly, depending on when producers release them.
Furthermore, we understand that you may actually want to play these games for real money. Our information (and review) collection has started to add online casinos where you can play slots, as we currently list over 2,100 brands.
We took things even further and added bonuses to the mix. You should always be ready for gameplay and armed with as much help as possible. Our site has over 25,000 offers in its database.
SlotsCalendar also conducts interviews with iGaming industry figures discussing the state of the industry, present in our News section, while our Blog provides various informative articles.
How We Review and Test
SlotsCalendar’s entire reviewing process follows the system established by our reviewing methodology. It sets up all the steps that we follow and all the details that we check in the verification process.
For slots, our reviews investigate basic and bonus features, key metrics like the RTP, and then test the free versions listed on our site. Stress-testing allows us to see if the game is stable, while user experience evaluation is the overarching objective.
In the case of casinos and bonuses, we check the terms and conditions carefully, create real player accounts, and conduct testing by redeeming offers. We try to go through each promo’s wagering and, if we clear it, we request a cashout to verify if the casino pays.
If we have actual proof that a casino does not pay, we flag it accordingly as untrustworthy through labeling, rating, and a statement in its review.
The People Behind SlotsCalendar
We are a collective of industry experts with specialized knowledge of the iGaming sector. Our effort is spearheaded by GSH Online Media CEO and SlotsCalendar Chief Editorial Officer, Viorel Stan, whose leadership sets our standards with his hands-on approach in both our commercial and editorial operations.
Each member of the SlotsCalendar editorial team is a seasoned professional with years of experience under their belt, both as grassroots gamblers and advanced experts.
The Strengths of Our Team
We know how to test, research, and manage information to compile everything into a cohesive product.
Our editorial staff members, such as Valentyna Stoilovscaia (slot reviews), Andrei Vlaicu (responsible gambling), Steff Ryan (bonus analysis), and Alvin Harrell (casino reviewing), are highly knowledgeable in their respective specializations. Moreover, the entire team is versatile enough to provide guidance beyond their main specialty.
Our commercial and technical personnel work alongside them to provide you with relevant information on a functional platform. We are players who work in the service of fellow players. Our objective is to enhance your gaming enjoyment and encourage savvy decisions.
As such, we always put ourselves in your shoes and think as a casual player would think. We understand that relaxation and entertainment are the key purposes of playing games of luck, and that’s what we’re trying to focus on.
Editorial Independence and How We Make Money
SlotsCalendar’s revenue model comes from commissions we receive when you sign up and deposit with the operators we list through our affiliate links or bonus codes. Some of these offers are exclusive and carry a tag; we negotiate with casino operators before listing them.
However, we commit to maintaining our editorial independence and applying the same rating formula after testing these offers with the same rigor.
We will always tell you when a game is unimpressive, when a casino is a scam, or when a bonus is a toothless marketing ploy. That’s why you’ll find low ratings on various products that we list and evaluate, but also why we publish casinos and promos with the ‘Not Recommended’ and ‘Blacklisted’ tags, letting you know what to steer clear of.
It’s also possible that some data on our site is wrong. Casinos change their listings and terms without notifying us. If you encounter an issue, please refer to our complaints service.
The SlotsCalendar Community
SlotsCalendar is a place for gaming enthusiasts to gather, learn, and enjoy themselves.
To support this sense of community, we provide specialized avenues for it: our forum, an annual set of awards voted on by players, and an entire system of social slot tournaments.
The Forum
SlotsCalendar’s forum is a hub that our community can use for general discussions, news and Q&As, or threads about specific games, casinos, and offers on our site.
Unlike the split among markets and GEOs that separates the localized versions of SlotsCalendar, the forum is a centralized portal available to users worldwide.
The SlotsCalendar Awards
Unlike many similar initiatives in online gambling, the SlotsCalendar Awards are decided exclusively by user voting rather than by a jury panel. The motto of our awards is ‘iGaming’s best, chosen by players,’ which reflects our commitment to a community-driven process.
The first edition was in 2024, and the ceremony has been held annually since then. Both the categories and the ceremony locations have changed across editions.
SlotsCalendar Social
The SlotsCalendar Social experience is a collection of free slot tournaments. We host such competitions consistently and allow you to socialize and compete with other players. Furthermore, the best-placed competitors win a prize with real money value.
The motivation behind this concept is that we chase new horizons and aim to create new opportunities for our users, whether new or dedicated.
Player preferences, market shifts, and our own trailblazing ideas are the main inspirations for our continuous journey. Since we’re already known for providing slot gameplay at absolutely no cost, why not let you play them competitively?
These tournaments are possible thanks to our partnerships with industry-leading game providers.
Our commercial deals with trusted game provider partners and collaborators enable you to play their games for free, climb our social tournament leaderboards, and win. For our part, we run them on our own infrastructure, integrating providers and handling leaderboards and prize distribution.
The overarching element behind this initiative is our love for the game. What do we mean by game? It’s the phenomenon we’re dealing with. We love interacting with the industry, we love bettering ourselves, and we definitely love helping you improve your experience.
What Our Users Say
SlotsCalendar currently enjoys a 4.8⭐ rating (out of 5) on Trustpilot, aggregating close to 3,500 reviews from users across the various markets from which our community hails. We constantly strive to win and nurture the trust of our users.
Industry Recognition
While the gratification from our users is the primary driver of our brand, we cannot help but be grateful for the recognition we received from our peers in the industry.
SlotsCalendar has won several awards from AffPapa’s iGaming Awards throughout the years, which are the following:
Slots Review of the Year Award (2022 and 2023)
Best Branding Awards (2024 and 2025)
Branding of the Year LATAM (2025)
Slots Review Affiliate of the Year (2026)
Where Our Slot Data Goes
SlotsCalendar is GSH Online Media’s slots-oriented flagship, making it the main collector and aggregator of slot and casino-related data within the company’s structure.
Another one of its roles is to power another GSH flagship product, BetBrain, whose focus is on sports betting. SlotsCalendar’s database carries over to BetBrain’s free slot setup, supplying it with the slots and game-specific information that it lists.
Playing Responsibly
Our service to you, the player, also includes encouraging responsible gambling. Realizing the risks and possible fallout of gambling is our duty to our users. We want to steer you toward playing responsibly and taking care of your mental health and finances.
Responsible and safe gambling are priorities for us, which is why we intend our product for 18+ people or older, depending on the gambling regulations in your applicable jurisdiction.
We formally encourage setting deposit and loss limits when playing at any of our listed casinos, and opting for short sessions and emotional control. Check out our responsible gambling statement for additional pointers.
