Slot machines have been around since the late 1800s, when the first slot machine was introduced. This machine was simple, and featured three wheels that used hearts, spades, clubs and diamonds. These machines were immediately popular, and their use spread rapidly. The slot machine was considered to be revolutionary for the time, with the first actual machines weighing over 100 pounds and were made from cast iron.
As the slot machine evolved, fruit symbols began to be used in place of the hearts and other symbols normally associated with poker. Other symbols began to appear in other slot machines as more were produced. Horseshoes and stars were among the most popular choices for slots symbols. Over time, slot machines would use other symbols to create a unique and fun slot machine experience but the most frequently seen symbols are fruit or card suites.
The first slot machines offered a small payout for those who matched the symbols accordingly, with later machines offering larger payouts. Different amounts began to be offered for slots, such as penny, nickle and dollar slots, each with their own pay out amounts. Many casinos offer slot machines in various amounts, making it possible for all levels of gambling.
Slot machines came in two sizes, allowing casino and bar owners to find a machine that suits their needs. Table top slot machines could be easily placed on a bar counter or pedestal where it could be easily reached. Many modern slot machines are standalone machines that do not require additional support stands.
Electronic slot machines were introduced in the 1960s, and brought about a new level of entertainment for slots. Music, lights and other sounds were then able to be used as the electronic slot machines continued to evolve. From there, video slot machines were born, and made their first appearances in the 1980s. Video slot machines are often seen in casinos as opposed to the more traditional styles.
After video slot machines secured their place in casinos, the next evolution was to come. With the widespread use of the internet and video gaming came online slot machines. These online slot machines are most often available in online casinos and may pay out real money, similar to physical slot machines.
