What first comes to mind when you hear the term slot game? For trusted online gambling many it brings images of flashing lights and bells ringing in a Las Vegas or Atlantic City casino. At the start, slot machines were made from heavy cast iron, which made them hard to haul around and install.

By 1907, Charles Fey partnered with Mills Novelty Company and produced a line of new slot machines, including the Liberty Bell, which is known as the granddaddy of all slots. This paved the way for high-tech, sophisticated machines, into which millions of people plunk millions of coins.

Not too long after, several improvements were made to the machines, including lighter materials that made them much easier to transport. Some of the other improvements were replacing the heavy iron with a wood cabinet making the process of transporting and delivering the slot machine game much easier still.
