It all started with mechanical slot machines developed by Charles Frey back in the 1800s. The first electrically powered slot machines were released after the advent of electricity. These specimens now seem like prehistoric dinosaurs. In addition, they were new less than a hundred years ago. In addition, with the advent of computers and the internet, slot machines as well as casinos immediately infiltrated the industry. Just register to get a no deposit bonus and start playing.
It would be impossible to explain this phenomenon if the part of the brain responsible for gambling was not very close to the part of the brain responsible for basic instincts. Gambling moves to a new level of popularity as soon as there is a new round in the development of mankind.
Thus, if scientists invent a new source of energy or a new way of communication that becomes very popular, casinos will appear immediately. Nevertheless, let’s get back to slot machines. All slots fall into two main categories: classic slots and video slots.
Classic slots – “Back to the Past” and other classic slots look like real mechanical machines of the past generation. Such models have the usual three reel system. The standard number of reels and standard symbols (cherries, sevens, strawberries, etc.) distinguish this slot machine from others.
Such machines rarely have more than five paylines. In most cases, only with the maximum bet you can get the biggest winnings.
If you compare it to regular slot machines, video slots are much more like computer games. They basically have the same theme and plot. Many of them are based on famous movies, TV series or holidays. For example, there are many Halloween-oriented video slots. Some of them have a progressive jackpot.

Most video slots have five reels, but there are also slots with seven reels and even nine reels. Many video slots pay out winnings for winning combinations rather than the number of lines collected. The number of such combinations in one game can exceed a hundred.
You can categorize i-slots and GPPs into separate screens with exciting bonus games. These feature bonuses such as winnings that you can get if you can open one of three chests of gold. Or win an extra prize for guessing where the criminal is hiding.
