A Brief History Of Slot Machines
The history of slots goes all the way back to the late 19th century, when the first slot machines were designed and produced by Charles Fey, an American engineer living in San Francisco. His “Liberty Bell” machine contained three reels with five symbols each: diamonds, hearts, spades, horseshoes and a bell. This machine found immediate success and could be seen as the starting point of the slots odyssey. Throughout the first half of the 20th century, they have populated most land-based casinos in the United States and the rest of the world.
The first electromechanical slots saw the light of day in the 1960’s, but players had to wait until the late 1970’s to find what we now call a video slot. These machines grew more and more popular among casinos when it became economically viable to install slots with digital display. This video slot technology was quickly acquired by International Gaming Technology, that is now a leading online slot developer.
The internet revolution transformed the slots universe by liberating game designers from physical constraints. Ambitious developers such as NetEnt or Microgaming started creating some five- or six-reels slots, with crazy bonuses, free spins, and even progressive jackpots. All of these slot features and casino bonuses will be thoroughly analyzed in the following sections.
Physical vs Online Slots
As it has been stated above, online slots have the advantage of doing away with mechanical engineering constraints. But it is also important to remember that the line between online and land-based is not as clear cut. For instance, this liberation process had also started with the creation of video slots in the late 1970’s. Here are the main differences between playing traditional “physical” and online slots:
- Choice: Because online casinos are not limited by real estate or the cost of new machines, a single online casino could provide its users with several hundreds of different slots.
- Variety: In the online casino industry, slots are developed by a growing number of talented developers such as Microgaming, NetEnt, Playtech, or even smaller labels such as Yggdrasil or WMS. Thanks to this large number of creative minds, online slots fans will be able to experience different gameplays and designs.
- Higher RTP: The RTP (or “Return to Player”) describes the percentage of bets that a certain slot will pay back to its players over time. Because land-based casinos must cover a large variety of costs (maintenance, security, real estate…), they tend to propose slots with a lower RTP, and retain a higher percentage of players’ wager. Online slots’ RTP could rise far above 95%, granting the casino a lower edge than American Roulette.
- Higher Progressive Jackpots: As it will be described below, online progressive slots are linked to large scale jackpot networks and pools. This explains why online progressive jackpots could easily reach millions of dollars, something that would be unthinkable in land-based casinos.
- Generous Welcome Bonuses: Because online casinos do not benefit from a physical, geographical presence, they are encouraged to propose large welcome bonuses to attract new players. These bonuses are a great way to start playing with a healthy bankroll.
- Mobile gameplay: One of the main advantages of online slots is that they can be played anywhere, at any time. Be it a desktop computer or a smartphone, you will be able to start rolling in a few clicks.
Fruit machines could be found in land-based and online casinos, but also in bars, pubs and amusement parks. These simple, three reels slots have symbols that have now become famous such as the cherries, the seven or the “BAR”. Fruit Machines are the relics of late 19th century slots and are often chosen for the simplicity of their gameplay. Many nostalgic players will be happy to find these “retro” or “vintage” games on most online casinos today.
Video and 3D Slots
Video slots were created in the 1970’s, but it is only with online casino that they reached their full potential.
In the early 2000’s, game developers even started applying the advances of 3D animation to online slots, giving birth to 3D slots. Because there are no limits to these firms’ innovation spirit, slots players will soon be able to find Virtual Reality slots in all of their favorite online platforms. Video and 3D slots are characterized by a creative gameplay featuring slot bonuses, free spins, wild cards and scatter symbols.
The theme of these video slots is usually inspired from popular culture and famous movies. So, if you want to start playing on Jurassic Park or Indiana Jones slots, video slots are the way to go.
Here are the main differences between video and 3D slots, and fruit machines:
- Creative themes: Video slots moved away from the traditional 7’s, cherries or BAR, to create a new online gaming universe based on famous movies and popular culture.
More reels and paylines: Because video slots developers are free from physical constraints, they can include five or even six reels, with more than 20 symbols. These new designs allow a higher number of possibilities and sky-high jackpots.
- Free spins: Many video slots allow players to win both cash and free spins. Most players will appreciate this exciting way to stay in the game and try again.
- Scatter and Wild Symbols: In traditional fruit machines, symbols had a mechanical relation with one another. The jackpot was only triggered by a predetermined combination of symbols. Because video and 3D slots are ruled by a computer programs, their gameplay can be more sophisticated. For instance, some “Wild” symbols can act as win multipliers.
Progressive jackpots are one of the most exciting innovation brought by internet gaming. Progressive slots preexisted the rise of internet casinos, but it is only thanks to massive online progressive networks that jackpots can reach millions of dollars.
In simple words, a progressive jackpot is a jackpot that increases each time that the progressive slot is played and that the jackpot is not won. The way this works is that a percentage of each player’s wager goes directly to the jackpot pool until a lucky user takes it all. And with networks of several thousands of slot machines, progressive jackpots could quickly reach millions of dollars.
Progressive slots are one of the few games allowing users to win a life-changing amount of money in the click of a button. And every online casino gambler likes a quick hit once in a while.
Free Spins / Free Play
Free play is usually given by online casinos to new players as a part of their welcome bonus. It is also occasionally used to promoted a new game. It allows you to play slots without wagering a cent and still cashing in the wins, in other words, to play slots for free. Of course, these bonuses are tied to specific terms and conditions that must be checked before creating an account.
Free spins – what is better in online gaming than the excitement provided by spinning those reels for free while winning real money? A free spin is, as its name suggest, a spin on a given slot or set of slots where no stake is required. Once again, thanks to these slot bonuses, you could win a jackpot without wagering a cent.
In the online casino industry, online casinos take care of the marketing, customer service, and gaming platform design. However, game development is left to a handful of highly skilled developers that have by now created thousands of exciting slots to choose from. Here is a short description of each member of the online casino games development Trinity: Microgaming, NetEnt and Playtech.
