Live Dealer Casinos are casinos which mainly use the live host approach for their table games. Many casinos offer at least a few live dealer casino games, but use single-player software for most of their selection.
The reverse is also true. Live casinos may give punters the chance to play some software-based games, but there are heaps of live dealer games to enjoy.
The main difference is in the real money experience. When you play a table game powered by casino software, you can play for free or for real money. Since live casinos involve play with other people, they can only be played for real money.
The rest of the experience is the same. There will still be more real money pokies than anything else, banking will be done the same way, and both will still offer the same kinds of casino bonuses and promotions.
