Video slots are much like slots except the dials and paylines are all displayed on a video screen. They are the video answer to the slots machine in a box. They can be found at land based casinos as well as online casinos and even at bars, pool halls and restaurants depending on the laws of the state or country they are in. Video slots are a popular variation form some of the other games that can be found at an online casino because they are simple to play and don't require the player to learn a tough playing strategy or to practice a lot. There are many thematic variations of the game at different online casinos on the net.

Slot machines appeared in the USA in the 1890's. The first 3 reel slot machine was invented in San Francisco in 1898/99 by a German immigrant named Charles August Fey. The machine was called Liberty Bell and had symbols of Bells, horseshoes, diamonds, spades, and hearts on its reels. Charles Fey manufactured and rented out his slot machines to gaming palaces for 50% of the profits.

Fey also created the first draw poker machine in 1901 and the first silver dollar slot machine in 1929. Slots were made illegal in San Francisco in 1902 and the ban soon applied to the whole of California and Nevada. This didn't stop the inventor from continuing to manufacture his slot machines.
