Slots are one of the main revenue-generators in casinos, but they can be very addictive and there are many people who find it difficult to quit playing them. This article explores how casinos try to encourage players to play for longer by changing their game design.
The first slot machines were introduced in the 1800s and were a hit with saloon patrons, but soon forces of morality and the law began to restrict their operation. In the 1970s, video slots were developed that replaced the mechanical reels with computer hardware and allowed them to be updated without replacing the whole unit.
This is a great example of how casinos can improve their products by using data analytics to understand how players respond to new features. By introducing features that lower the house edge and increase the odds of hitting the higher paying symbols, casinos can reduce player defection rates and increase revenues. This is a win-win for everybody involved, but it requires that casino management is willing to change long-held operating and marketing strategies.
