The house edge is derived from the gap between the true odds of an outcome and the payout odds offered by the casino. If a casino paid out $1 for every $1 bet on a correct guess, it would have no edge.

Several platforms are already pioneering this space, offering detailed environments and interactive game mechanics that go far beyond point-and-click. The potential for social interaction is a key differentiator. You could meet up with friends in a virtual poker lounge, celebrate a big win at a virtual bar, or simply enjoy the ambient sounds and casino sights of a bustling casino floor—all from your living room.
