When slot machines where first invented they majorly used the symbols present in a pack of cards, namely, heart, diamond, spade in addition to horseshoe and a liberty bell. Just as slots themselves have gone through several upgrades since they were first invented and along with improved mechanics, the symbols have also evolved with time. Today one can see a wide variety of symbols used in slot games like fruits such as cherries, orange, apple and even images of gemstones in various shapes and colors, along with other common symbols such as star, crown, clover etc. We love pokies! The spirit of slots remain the same but the look and feel of them have indeed changed down the line thanks to the many iterations to the slot symbols.
