Looking at 2025 through the data published by major regulators, a fairly clear picture emerges. There is still no single global database that measures all regulated online portals in a uniform way, but official statistics from the most mature markets reveal converging trends. Within authorized systems, online casino games — and especially digital slots — continue to dominate in terms of revenue and activity volume. Sports betting remains one of the main entry points in terms of number of users and frequency of use, while poker and bingo maintain a smaller but stable presence.
This is an important distinction because it shifts the discussion from the broad concept of online gaming to a more precise map of preferences within regulated environments, where official classifications, licensing controls, and traceable offerings play a key role.
The digital gambling landscape is evolving rapidly, with many players now seeking the anonymity and speed of blockchain transactions. While traditional platforms continue to dominate, the demand for casinos that accept crypto is reshaping how operators approach payment flexibility. These sites prioritize instant withdrawals and enhanced privacy, catering to a tech-savvy audience. As regulations catch up, the integration of digital currencies is becoming a standard feature for any top-tier gaming destination looking to stay competitive in 2026.
Online slots remained the center of the digital casino ecosystem
The clearest signal comes from European and North American markets where reporting is more detailed. In the United Kingdom, the Gambling Commission reported that the remote gambling sector generated £6.9 billion in 2023–24, with online casino games — particularly slots — accounting for £4.4 billion of that total. The regulator reiterated in 2025 that the online sector is increasingly driven by casino-style games, especially slot titles.
In Spain, the national regulator (DGOJ) reported an online gross gaming revenue (GGR) of €1.45 billion in 2024, with casino products representing 50.23% of the total. Within that segment, online slot-style games accounted for 64.62% of casino revenue. During the first quarter of 2025, the casino segment continued to grow year-on-year, again largely driven by digital slot games.
A similar pattern can be observed in Ontario, one of the most closely monitored regulated markets in the world. According to the 2024–25 iGaming Ontario report, casino games generated CAD 69.6 billion in wagers out of CAD 82.7 billion total — roughly 84% of all activity. In terms of revenue, the casino segment produced CAD 2.4 billion out of CAD 3.2 billion overall. The category includes slots, live tables, and digital table games, but the scale difference compared with betting and poker clearly illustrates how central casino gaming remained in 2025 within regulated portals.
In this context, mentioning regulated online slot platforms such as StarVegas makes sense only as an example of how recognizable licensed environments have become: in mature markets the crucial issue is not the promotion of gaming products, but rather the user’s ability to distinguish between authorized, regulated offerings and unverified ones.
Sports betting continues to have extremely high user penetration
Saying that slots dominate in revenue does not necessarily mean they always rank first in terms of user base. In several regulated markets, sports betting maintains remarkable cross-market popularity.
In Spain, the 2024 annual report by the DGOJ showed that betting accounted for 41.86% of the total online GGR, second only to the casino sector. Interestingly, betting also recorded the largest number of participants, with 1,568,197 users — more than any other gaming category. The first quarter of 2025 confirmed the vitality of the segment, with sports betting growing 11.17% year-on-year, although results varied between traditional bets, live betting, and horse racing.
In the United States, where regulated online gambling is organized state by state, 2025 again highlighted the importance of betting as a major driver of engagement. The American Gaming Association reported that U.S. commercial gaming revenue reached a record $78.72 billion in 2025, with growth across all three main verticals. In Pennsylvania, one of the most developed markets, sports wagering revenue rose to $602.5 million in 2025 with a betting handle of $8.8 billion.
While sports betting is not always the largest segment in terms of revenue, it remains one of the most visible and widely adopted formats, particularly in contexts where users initially access platforms to follow sporting events before exploring other products.
Live tables and non-slot casino games strengthened their position
When discussing online casinos, reducing the entire category to slots would be misleading. Part of the growth observed in 2025 also came from live dealer tables and digital table games.
Spanish data clearly illustrates this point. In 2024, alongside the expansion of slot-style games, live roulette grew by 10.41% and blackjack by 3.80%. In the first quarter of 2025, some table-based formats such as punto banco recorded even stronger quarterly increases.
In New Jersey — a key reference market for regulated online gambling in the United States — official statistics for late 2025 distinguish between peer-to-peer games and “Other Authorized Games” within internet gaming. The latter generated $2.88 billion in revenue compared with only $30.3 million from peer-to-peer games, demonstrating how non-slot casino offerings, including table games and similar formats, remain significantly stronger than poker.
This helps clarify a point that is often overlooked: in modern regulated portals the casino category is not a single block but rather an ecosystem. Slots act as the main revenue driver, while live casino tables and digital table games serve as a second pillar of the offering. The same pattern is visible in Ontario, where the “casino” category — aggregating slots, live tables, digital tables, and bingo — accounts for the overwhelming majority of wagers and revenue.
Poker and bingo remained smaller but stable segments
Looking at the 2025 data objectively, poker and bingo appear more like niche segments within regulated online gaming rather than major growth engines.
In Ontario, peer-to-peer poker generated CAD 1.7 billion in wagers and CAD 66 million in revenue — far behind the casino category’s CAD 69.6 billion in wagers and CAD 2.4 billion in revenue. In Spain, poker represented 6.88% of total online GGR in 2024, while bingo accounted for just 1.06%. During the first quarter of 2025 poker even experienced a slight year-on-year decline, while bingo maintained modest but stable volumes.
In New Jersey, peer-to-peer gaming produced $30.3 million in revenue in 2025, again vastly smaller than the internet casino segment.
This does not mean these games are irrelevant. Rather, it suggests that poker and bingo attract more specific audiences. They perform well within multi-product platforms but rarely drive the entire market on their own.
What the global data actually shows about 2025
The most balanced summary is this: in 2025, across regulated online portals in the most transparent markets, the most widely used and economically dominant category was online casino gaming, with slot titles representing the largest share. Sports betting followed closely, often representing the category with the broadest public reach. Live casino tables and other casino games formed the next tier, while poker and bingo remained smaller complementary segments.
Denmark provides an additional confirmation. According to the national gambling authority, online casino and betting together already accounted for more than half of the country’s gambling market, and monthly figures for 2025–2026 show these two segments as the most dynamic in terms of revenue growth.
