Fast forward to 1976 and the very first video slot was launched. This paved the way for slots to become more advanced, not just in their graphics, but also in their features. Video slot machines became hugely popular at land-based casinos and still are today. Then in the late 90s the first online casino slots were launched, with mobile friendly slots coming out in 2004. If you deposit real money on a slot game, it’s possible to win a cash prize.

Originally made famous in Las Vegas and other land-based casinos, this popularity has now been moved online.
