When you walk into the bright lights, soaring ceilings and the clinking sound of slot machines, it’s easy to be drawn in. You stride into the casino brimming with confidence, your wallet filled to the brim with cash and plans for an enjoyable, sensible evening of gaming and maybe two rounds of drinks. But hours later you are staring at your empty wallet wondering what the heck happened to your money. Casinos use every trick in the book to lure you in and keep you gambling. From sounds to the physical design, here are nine tricks casinos use to make it hard to walk away from your money.

1. Encourage Positive Reviews

Casinos rely on word of mouth and social media to attract new players and keep existing ones coming back. Displaying video testimonials of happy guests and winners on your website or social media can go a long way toward building trust with potential visitors.

2. Offer Comps

Casino operators give out free goods and services to “good” players, or people who spend a lot of money playing slots and other games. These are called comps and can include hotel rooms, show tickets, restaurant meals and even limo service and airline tickets. These perks are given to reward high-spending customers and keep them returning.

3. Pursue Events and Group Business

Casinos are also perfect locations for large events like weddings, conventions, corporate retreats and family reunions. To help attract these types of clients, promote your casino’s flexible event spaces and cutting-edge technology on social media and search ads. You can also use Cvent’s Competitive Market Ads to target planners in sister markets or those looking for similar destinations, helping you win group business you might otherwise miss.
