Slots were invented in New York in the year 1891 based on the game of poker. It was nothing like the modern digitalized slot machines where everything happens with the push of the button. This machine gained popularity in bars and other hangout places and worked by pulling a level which would roll the drums. Bars had customized these machines to give out combos or free beverages, for example, a king and a queen will buy you your favourite burger or whiskey. In 1987 an inventor from California had come up with a fascinating slot machine known as the liberty bell. It had three slots with symbols of cards, and the biggest prize could only be won if one gets three bells. This became so popular that in the following year all local businesses like cafes, pizza stations, supermarkets, restaurants and burger stand had a liberty bell placed in the centre. Until today, most casinos have a digitalized version of this game.
