Which Crypto Casino Is Actually the Biggest?

Crypto casinos went from being the slightly weird cousin of online gambling to quietly becoming a huge part of the market. Internally, nobody treats them as a side project anymore – they are right in the middle of the conversation.

Earlier this year, we ranked the biggest casino operators in streaming based on their visibility across Kick, Twitch and YouTube, and we also took a closer look at the largest casino streamers themselves. Many of the same names show up again when we stop looking only at who dominates the streams and instead ask a simpler question: who is actually the biggest crypto casino overall?

In this article, we are not ranking “best bonuses” or “nicest design”. We look at traffic, deposit volumes and growth trends for the main crypto brands and try to answer who sits on top right now, and how far ahead they really are. The short version is that Stake is in a league of its own, with Rainbet, Shuffle and Roobet making up the next layer.

Stake – The Benchmark Everyone Else Is Chasing

Stake started in 2017, which is not that long ago in the bigger picture, but the way they’ve grown since then is anything but normal. When we look back at our own tracking spreadsheets from the last few years, the one constant is that Stake sits on top – and usually by a wider margin than the year before.

Let’s start with the traffic, because that’s what most people look at first:

• Ahrefs estimates around 2.3 million organic visitors per month to stake.com.

• Semrush puts total monthly visits at over 50 million.

• Similarweb, which we generally find to be closest to reality with around a 20% error margin either way, shows roughly 80 million monthly visits.

Even if you apply a generous error band, Stake is miles ahead of the other crypto casinos in terms of visibility and reach. But traffic doesn’t always equal volume, so it’s worth looking at deposits as well.

One of the more interesting datasets we’ve looked at is a breakdown of annual deposit volume for the largest crypto casinos. Stake sits at an estimated 21.8 billion in deposits, which is more than four times the second‑placed brand in that table. Once you see those numbers, it becomes very hard to argue that anyone else is close overall.

On the surface, people see streamers, big sports sponsorships, celebrities and a barrage of content. Under the hood, Stake has built a machine that most of the newer crypto casinos are now trying to copy in their own way. They also behave more and more like a traditional, mature operator – including M&A moves and expansions into regulated markets – while still keeping crypto at the core.

If you’re just looking for the biggest crypto casino by almost any reasonable metric, it’s Stake. The rest of the article is basically about who’s lining up behind them.

Rainbet – The Fastest‑Growing Challenger

When Rainbet first started to show up in our data, it looked like yet another Stake‑inspired project. A few years later, it’s very clearly much more than that. If you talk to affiliates and content creators who work a lot in crypto, Rainbet has gone from “who?” to “we send quite a bit there” surprisingly quickly.

On the traffic side, the numbers roughly look like this:

• Ahrefs: around 1.1 million organic visitors per month.

• Similarweb: just over 20 million total monthly visits.

That’s a strong profile for an operator that is still relatively young, and one of the cleaner SEO growth curves we’ve seen on the operator side in this space. They’ve lifted Stake’s playbook, but they’ve also executed well on it – especially around search and content.

On the deposit side, the same dataset that showed Stake at 21.8 billion puts Rainbet at around 1.57 billion in annual deposits. That’s obviously a different weight class than Stake, but it’s enough to put Rainbet in the top cluster of crypto casinos by volume.

You sometimes hear the argument that as Stake focuses more on regulated markets, a brand like Rainbet can keep hoovering up the pure crypto crowd. If they continue on the same trajectory with product and marketing, it’s not a crazy prediction.

Shuffle – Smaller Numbers, Strong Reputation

Shuffle is an interesting case because their reputation in the industry is stronger than their raw traffic numbers suggest. When we talk with C‑level people and high‑value players about where they actually like to play, Shuffle comes up a lot more often than you’d expect if you only looked at Similarweb.

The data we’ve looked at is roughly:

• Similarweb: around 5 million visits per month.

• Ahrefs: about 40,000 monthly organic visitors.

So, in terms of search and overall traffic, Shuffle is clearly smaller than both Stake and Rainbet. Where they seem to compensate is on product and player quality. Industry reports that look at deposits suggest that Shuffle processes about 2.32 billion in annual deposits – ahead of BC.Game and Rainbet in that particular table, even though they have less traffic.

If you only think in terms of “who gets the most clicks”, Shuffle is not near Stake. If you ask “where do serious crypto players and insiders actually play and deposit meaningful amounts?”, the picture is a lot closer.

Roobet – The Early Streaming King

If you watched casino streams a few years ago, you watched Roobet whether you realised it or not. For a period, they had something close to a monopoly on many of the early streamers, especially on YouTube, before the rest of the market caught up and more brands got in on the action.

Today, the top‑line numbers look like this:

• Similarweb: almost 2.5 million monthly visits to roobet.com.

• Ahrefs: around 800,000 monthly organic visitors.

That puts Roobet below Rainbet in total visits, but with a solid organic footprint and a brand most stream‑watching players still recognise. On the deposit side, Roobet ranks as the second‑largest crypto casino in the same dataset we mentioned above, with around 5.16 billion in annual deposits – ahead of Shuffle, BC.Game and Rainbet, but well behind Stake.

In other words: if Stake is the current benchmark, Roobet is the older streaming powerhouse that still operates at serious scale, even if newer brands have started to eat into the visibility they used to enjoy alone.

Why BC.Game Is Not in the Ranking (Even Though It’s Big)

BC.Game is one of the names that always comes up when people talk about crypto casinos. It’s absolutely a large operator in this space, both in terms of player base and volume.

The reason we haven’t tried to give BC.Game a specific place in this ranking is simple: data quality. BC.Game operates across several domains and structures, and once you start adding all of those up with external tools, the error margin gets too big to feel comfortable pinning a number on it.

What we can say is that in the deposit‑volume data we’ve seen, BC.Game sits at around 2.08 billion in annual deposits, which puts them in the same cluster as Shuffle and Rainbet, and clearly above most smaller crypto projects. If we ever get a cleaner, consolidated picture of all BC.Game traffic and volume, we’ll revisit this – but for now, we’d rather be honest about what we know and what we don’t.

Is the Biggest Crypto Casino Automatically the Best?

The short answer is no. It depends entirely on what you care about as a player.

There are plenty of players who actively seek out smaller or newer casinos because that’s where you often find stronger upfront bonuses, aggressive VIP deals and operators who are still hungry enough to say yes to custom requests. At the same time, the biggest crypto casinos have something that’s hard to copy: stability, deep liquidity and long‑term loyalty systems that can be extremely valuable if you actually stick with them.

One thing we hear a lot from affiliates is that crypto players are more loyal than “regular” casino players. Once they feel looked after at a brand, they don’t jump around as much just because “the grass looks greener” somewhere else. That dynamic naturally benefits the biggest brands – but it also means that new crypto casinos have to do more than slap on a welcome bonus if they want to pull people away from Stake, Roobet, Shuffle or Rainbet.

And, just like with VIP programs, scale cuts both ways. A very big brand can feel safer and more established, but it can also make it easier to lose track of how much you’re actually playing because everything looks slick and normal.

How We Got to These Numbers (And the Weak Spots)

It’s getting harder and harder to say exactly how big an operator is from the outside, and crypto casinos add a couple of extra layers of noise. For this article, we’ve mainly leaned on:

• Ahrefs for organic search estimates.

• Similarweb for total visits and relative scale.

• Semrush and similar tools as extra checks where relevant.

• Public datasets on estimated annual deposit volume for the largest crypto casinos.

These sources are helpful because they show trends and relative differences, but they are not perfect. They don’t fully capture:

• Traffic and volume from private affiliate deals, invite‑only communities and closed groups.

• The effect of VPNs, mirrors and alternative domains.

• App usage or direct wallet connections that don’t show up clearly in web traffic.

So you should treat all of the numbers above as ranges and indicators, not as exact, audited financial statements. The patterns are clear – especially that Stake is far ahead, and that Rainbet, Roobet and Shuffle are now operating in the same big‑league cluster – but there will always be some uncertainty when we look from the outside.

What Will This List Look Like in a Few Years?

The interesting part will be seeing what this list looks like in three years’ time. This space is constantly evolving, and the level of innovation is much higher than at a typical “.com” casino. It wouldn’t surprise us at all if, in 12 or 24 months, the ranking looks completely different from what you’re seeing here – which is exactly why it’s worth keeping an eye on.
