The slot machine entered cyberspace in the mid-1990s. Internet Casino was the first online casino. There you'd find most of the games players still enjoy today, though they've evolved and become more sophisticated.

A wild symbol is distinct from a scatter. It is a wild card icon that can complete any winning payline. There's a lot to keep track of on some slots, so keep your notepad handy.
