Las Vegas casinos are struggling to understand and implement three important new products. For one reason or another, skill-based games, esports and Bitcoin have yet to meet expectations of experts in Nevada. That admission comes from a couple of top Las Vegas authorities, as reported by the Las Vegas Review-Journal.

Skill-based games started finding their way onto casino floors in just the past few years, but customers haven’t taken to them yet, disappointing gambling observers. Chris Grove, managing director for Eilers & Krejcik Gaming, said, “The hype around skills-based gaming was so significant that I think it created a proportionate backlash.”

The new Nevada Gaming Control Board (NGCB) Chairwoman Sandra Morgan isn’t giving up on the trend just yet. “Skill-based slot machines have not gained significant popularity on the casino floor but there are still innovators developing these types of games to gain better traction with a younger demographic,” she said, according to the report.

Grove also noted that new games rarely become a hit within just a few months. And as Morgan notes, these types of games might only become more popular as Generation X and millennial gamblers become more common on xasino floors.
