One basic difference is accessibility in that online casinos may be enjoyed from your computer, phone, or tablet, while playing at a brick and mortar gaming room involves traveling to the casino and often spending money on food and lodging. In addition, the vast majority or games at online casinos are software-driven, although most Internet casinos do offer some live dealer games, while a vast majority of the table and card games at land-based casinos are run by real dealers. Another major difference involves the return to player (RTP) on slots, which ranges from 89% to 99% online and from 75% to 88% at a land-based casino.
