Why Do Casinos Partner with IGT?
As one of the most popular online casino software providers, IGT has been leading in slot machine performance. A prime example is the Wheel of Fortune slot series, which has generated over $3.5 billion in jackpot payouts (Source: IGT Jackpots) and continues to be one of the most profitable slot franchises in history. Casinos invest in IGT because its games retain players longer and generate higher bets per session.
Furthermore, IGT’s Floor Manager Analytics helps casinos analyze which slot machines perform best. For example, when a Buffalo-themed slot machine is outperforming a poker-based slot in a high-traffic area, the casino uses IGT’s data insights to swap underperforming games out for more profitable ones.
IGT games also combine modern mechanics, bonus features, and familiar branded themes that keep players coming back. Below, we explore the most popular slot games that continue to dominate IGT online casino floors.
