One of the reasons why slot machines were introduced before was that some people in the gambling industry wanted a new game that wouldn't be too complicated for people who just want to have fun while gambling. When the slot machine was introduced in the gambling industry people took to it like bees on honey. They loved the noisy box with the colorful lights and they loved it even more because you never need to learn complex strategies or calculations in order to play it. All a player has to do is pull on the lever and hope to the heavens that spinning reel would stop with a winning combination. It's that simple, it's that direct and people loved the contraption because of its simplicity and yet exciting game.
Nowadays, slot machines have evolved and went on to become digital gambling games along with other table and card games when casinos started moving onto the internet. Online slot machines are the new rave for the 21st century gambler and with so many online slot machines emerging almost every week the people who design them are becoming more and more creative.
Back then, slot machines had simple designs. The earliest slot machines only had card numbers or faces on the reels, or some of them had fruits painted on the reels which the player had to match together. But with so many online slot machines emerging the design of each game had to be better than the others, which is why these days slot machines have become like a canvas where artists paint their masterpieces. And there are a lot of online slot machines out there that have very beautiful designs.
One of the most famous designs for an online slot machine is the pirate theme. Even during its earlier days, slot machines were already sporting pirates and their booty on the reels. When slot machines went online pirates often still graced some of the reels but they were also used for other purposes. Some slot machines based the whole layout and their game on pirates naming their bonus rounds or promotions as their “booty” or “buried treasure” and players would have a wonderful time trying to win those pirate treasures.
Another famous theme for online slot machines are films or movies. The Godfather movie is a classic online slot machine theme and some virtual poker machines have these enigmatic characters on their game layout. They would even provide a back story for the game, saying that the player is the Godfather's loyal ally who has to win the bonus round in order to save the Mafia family. This theme is a cool design especially for those who love Coppola's film. Just don't try to emulate the Godfather too much and start shooting your computer if you don't win.
Another often used and wonderful theme that designers use on their slot machines is the jungle theme or Aztec design. A lot of people associate wealth and buried treasure with the Aztecs or ancient South American tribes probably because of the famed El Dorado legend, which some people still believe to be true. That is why some online slot machine designers chose to base their games on the Aztecs to make punters feel that they're actually searching for the legendary city of gold. And if these gamblers win the jackpot they might actually believe that they've found their gold.
