From America the popularity of the game rapidly spread to other parts of the world, most notably Europe, Africa, South America, and Australasia. The nickel and quarter machines attract the vast majority of slots players, but throughout the evolution of slot machines from 3-reel to video and progressive slots, there are now many machines that accept dollar bills in several denominations.

At many casinos around the world today, there still are some classic three-reeled slot machines, but you can also find five, seven, and nine-reeled machines with huge variations of symbols, pay-lines, the amount of the jackpot including progressives, and the wager amounts.

And then when the internet came along, it was only a matter of time before virtual slot machines were developed so that the game could be played online which meant players were no longer require to use buttons or pull levers to spin the reels. The arrival of many internet gaming companies has seen hundreds of modern online slot games developed for online consumption, and due to the fierce competition in this industry, they all offer some very lucrative sign up bonuses to get new customers to sign up and make a deposit. One of the great things about playing slots at online casinos is that free to play slots became a possibility.

When looking at the history of slot machines, if it wasn’t for Charles Fey’s original slot machine concept that became a reality in the 1880s the casino industry wouldn’t have thrived to become what it has today. Now, slot machine manufacturers have moved into the online casino space and with social gaming’s tremendous growth, things are looking good for progressive gaming companies looking into the 21st-century and beyond.
