iGaming Business Casino Review: An Inside Look at the Top Online Casinos and Casino Games
Produced annually by iGamingBusiness with eGaming Monitor, the Casino Review maps growth and contraction across online gambling. Its 2023 edition drew on information from 3,400 online casinos to identify industry patterns. This account looks at the report’s findings on suppliers, studios, game categories and dealmaking.
Industry at a Glance
The 2023 figures from eGaming Monitor counted 744 studios active in iGaming, an increase of 18% over the year before. The report drew on 40,642 distinct casino games listed across 2,450 unique websites. Compared with 2022, that broader dataset gave analysts more material to assess patterns in online casino content. For readers, it provides a detailed view of the game selection casinos offered in 2023.
Suppliers and Studios
The supplier count climbed by 232 between 2022 and 2023, reaching 1,637. Studios accounted for the largest category at 48.9%; aggregators and other platforms followed with 20.6%. The market also saw almost 129 studios launch in the previous year, alongside 52 entrants among platform providers and aggregators.
Changing Shares
The ten largest studio groups still controlled 55% of game placements worldwide in 2023. Yet the arrival of many providers reduced those leaders’ combined share by 1%. Evolution Gaming remained the most widely represented provider, with a 13% share across global gaming sites, although that was slightly below its 2022 position. Playtech and Light & Wonder also lost share, while Playson and Inspired Entertainment dropped out of the top ten.
Play’n GO and Pragmatic Play expanded their content reach amid greater competition. Pragmatic Play held an 11% market share, and Play’n GO had 5%. Ranked by how many casinos carried their games, Evolution Gaming and Pragmatic Play remained among the leaders. Evolution Gaming content appeared on 83% of global casino sites in 2023, making it one of the most broadly distributed catalogues.
Parent and subsidiary structures also shaped supply. Larger supplier groups provided 68% of the gaming content on casino sites in 2023, down from 70% in 2022. That marked a change from the earlier pattern, when large groups continued to gain share even as the number of studios rose.
The report linked the shift to an 18% year-on-year increase in studios in 2023. New entrants added competition for visibility and space alongside established providers. That can mean familiar studios account for a smaller share, while new releases and ideas broaden the range of content available.
Game Supply
Globally, casino sites recorded a 50% increase in the number of games they offered. The report attributes the expansion to additional casinos and their growing catalogues, while older titles generally remained on the sites rather than being removed. Together, those factors increased the overall volume of listed games over the year.
The growth in studio output added to the range of games carried by casino websites. Among studios that were not dormant, average production reached 2.36 games per month in 2023. More than 10,000 new games entered the market overall, while a casino website featured material from an average of 59 suppliers. The report ranked the ten studio groups with the highest game production in 2023 as follows:
Studio Group Games Launched in 2023 Games Global 329 Pragmatic Play 313 Evolution Gaming 303 Playtech 188 Spinomenal 181
Game Categories
Slots dominated the mix of content recorded across gaming sites. They represented 84.8% of games at online casinos, with online slots well ahead of Live Casino, which made up 6.6%. The study also noted that newer formats, including crash games, were gaining share, though from a much smaller base.
Crash titles accounted for 0.3% of the industry in 2023, compared with 0.1% in 2022. Their presence extended across many gaming websites even though they remained far less common than slots and live games. The report also observed that crash games often appeared in prominent areas such as ‘featured’ and ‘popular’ sections. These placements suggest operators were giving the format visibility as interest in new game types grew.
Studio Groups by Game Placement
The report used top casino games as another way to compare studio groups, counting how many websites featured each title. The top 20 positions were held mostly by Pragmatic Play, Evolution Gaming and Play’n GO. There was also one entry apiece from NetEnt and Red Tiger in the top 20. The three highest-ranked games were all from Pragmatic Play: Gates of Olympus, Sweet Bonanza and Big Bass Bonanza. Slots made up most of the top 20, though live games and roulette versions appeared as well, indicating that those formats remained represented alongside slots.
Below are several notable game titles. Their listings provide a starting point for exploring individual game reviews:
Emerging Themes
Branded games and Megaways titles represented a smaller share of all gaming content in 2023. Action & Adventure, Animals & Nature, and Tales & Legends ranked as the leading themes by player interest. Sports and calendar-related themes recorded some of the largest increases in their share of game content.
Deals and Partnerships
In the aggregator segment, EveryMatrix ranked first, having added agreements with 19 studios during 2023. For distribution partnerships, 7777Gaming and Endorphina led the studio list, each completing nine deals in 2023. Slot naming showed a separate shift: just 11% of new slot machines carried a title already used by an existing game. The comparison figure had been 15%, a difference the review presents as evidence of rising originality in slot names over the year.
Report Takeaways
