From publisher's website:
Competing to build the most famous casino-hotel is thrilling, but doing so on a flimsy paper playmat isn't. This neoprene mat with a rubber backing provides a stable surface to construct the slot machines, lounges, restaurants, and other casino rooms you build while facing off against your opponents.
This "Nevada City Casino Clash" playmat is designed to be compatible with games in which casinos in cities like Las Vegas have showdowns. If you know of a game like that which uses thin, flimsy paper mats for each player's casino, then this neoprene mat is a luxurious alternative.
