St Patrick’s Day – Irish Themed Casino Games
Why So Many Irish Games?
In the period leading up to St. Patrick’s Day, Irish-themed games feature prominently on casino websites worldwide. Each March, casino platforms are inundated with slots showcasing lucky leprechauns, pots of gold at the end of the rainbow, and Celtic charms. However, in recent years, other themes have emerged to challenge the dominance of traditional Irish slots.
Irish themes are strongly associated with luck, a core appeal in gambling, thanks to symbols like four-leaf clovers, leprechauns, pots of gold, and horseshoes. These elements, along with bright colours, cheerful music, and lively characters, create an engaging and enjoyable experience for players.
Back in 2016, the dominant online slot game was Rainbow Riches by Barcrest (now Light & Wonder). Over the years, the trend has been clear: when a slot game achieves significant success, a wave of similar games inevitably follows. These games often mimic not just the mechanics but also the overarching theme. This trend, combined with the annual St. Patrick’s Day celebration, has ensured the continued popularity of Irish-themed games.

Top 20 Irish Game Launches 2025
The consistent success of Irish-themed slots has led to multiple new releases each year. The table below presents the top 20 Irish-themed games launched in 2025. Luck’s Wild Pub, which debuted in mid-February, has enjoyed the most global exposure, proving that players continue to resonate with Irish themes, particularly around St. Patrick’s Day.

Popularity By Country
Regional variations in slot game preferences exist, with themes like Buffalo games popular in the U.S. and Greek mythology-based games performing well across Europe. Despite these differences, Irish-themed games remain universally popular. A look at content share data from March 2025 indicates that the UK has a particular affinity for Irish-themed slots.

Other Themes Now Compete
While Irish-themed games remain a staple, other popular themes have developed. The graph below illustrates the percentage share of Irish-themed content each February compared to the rising popularity of fishing-themed games. The data shows a significant surge in fishing-themed slots, surpassing Irish-themed slots in exposure over recent years.

The rise of fishing-themed games can largely be attributed to the success of Fishin’ Frenzy by Blueprint Gaming, launched in 2017. The game’s popularity led to a series of sequels, inspiring other studios to create their own fishing-themed slots. A notable example is Pragmatic Play’s Big Bass Bonanza series, which has significantly contributed to the growing preference for fishing-themed games among players.
This trend demonstrates how slot game themes evolve over time, with successful titles often giving rise to entire subgenres. As Irish-themed slots continue to hold a strong seasonal appeal, their long-term dominance may depend on innovative reinventions and fresh gameplay mechanics to keep players engaged.
