History of Slot Games

A company called Stillman and Pitt, based in Brooklyn, New York, invented a 5-reel game in 1891 using 50 playing cards based on Poker.  They marketed this game to bars in the New York City area and it become very popular.  The prizes were determined by the bars themselves, rather than by the game.

The first true slot machine was developed by Charles Fey of San Francisco.   It used three reels, fewer symbols, and paid cash prizes.  Another early slot machine awarded prizes in fruit-flavored chewing gum, launching the long tradition of using fruit symbols on slot machines.

Although the earliest slot machines were mechanical in nature, manufacturers introduced electronic controls in the mid 20th century and made games fully electro-mechanical in the 1960s.  The advent of electronics reduced wear and tear on the machines and discouraged cheating.

In 1975 the first true video slot machine was developed by designers on behalf of the Las Vegas Fortune Coin Co.  The company was later bought out by International Gaming Technology (IGT).

In 1996 WMS Industries Inc. introduced a second screen “bonus” game for a slot machine called Reel ‘Em In.  And by this time online slot games were being developed by companies like Microgaming and Net Entertainment (now NetEnt).

Today there are thousands of different slot machines deployed in casinos around the world, including more than a thousand online slot games.  Game developers release new games every year and every few years advances in the technology make slot games more engaging and exciting.

Slot games can be interactive, feature multiple styles of bonus games, run in many different languages, support many different currencies, and can share jackpots in “progressive” channels that gradually build up value.  Although the latest casino games are still worlds ahead of the online games in some aspects, the most innovative online slot games provide rich user experiences and high payoffs.

3D technologies and fully orchestrated soundtracks are now becoming common with online slot games, allowing players to enjoy a robust casino experience in their own homes.  Some game software vendors also use the same animated characters across multiple games, so that players feel comfortable transitioning from older games to newer variations.

Online slots game designers may be licensed by major movie studios to produce games based on popular movies and movie franchises.  But because so many movies and books are based on popular themes from history and mythology it is relatively common for online slots games to introduce their own branded takes on myths, legends, and romantic fiction.

Some slots games even mimic (or mock) the casino experience itself, virtualizing the virtual world of online casinos in a tightly orchestrated in-game experience.

The world of slots games has progressed well beyond the concept of the “one-armed bandit” where you kept pulling a lever.  Game controls now allow you to adjust the amount of coins you bet per line, the value of the coins you bet, the volume of the game’s soundtrack, the quality of the graphics, and even to set up autospinning.

In fact, autospinning is an innovation that mimics some of the alleged cheats people have engineered.  Whereas gamers might have designed programs to keep the reels spinning for them in the past, now the game vendors do it for you.

The games run on random generated numbers.  Although science has yet to find a way to generate truly random natural numbers, the generator systems produce enough numbers that players cannot reverse-engineer the patterns.  The gaming experience is thus fair but equitable.  And the software is designed to provide a Return To Player (often denoted as RTP) in the range of 85% to 98%, meaning that on average between $0.85 to $0.98 is returned to the player for each $1 wagered.

Overall, it's an exicting time to be a slots players, with companies around the world working to develop innovative and new slot machine games.  We hope you'll enjoy the website and check back often for all the latest content from the Is The Most Comprehensive Slot Guides Online
