By the mid 1900’s there were numerous different versions of slot machines on the market and the idea of slots had already developed into a major industry. The first types of slots were known as one armed bandits because of the lever at the side of the machine that set the drums in motion. In time, this was discarded as the slot machine became more and more automated. By 1976 the first video slot could be found in Las Vegas which showed digital pictures and worked on electricity and did away with the original mechanical games. As the slot machines developed so did the industry, slots were placed at the entrances to casinos and in leisure centers across the world. Slot machine games became very popular in the UK at pubs where punters came for a drink and a quick game. There were three reel slot machine games and five reel slot machine games; in the UK the games were known as AWP, award with prizes games.
