The virtual gambling industry has been growing at an unprecedented rate in recent years, offering an incredible amount of entertainment, and among them, slots take the first place. New slot machines are added to studio portfolios almost every day, putting considerable effort into diversifying the gameplay. However, the sound accompaniment is equally important, as it should be as appropriate, qualitative, and interesting as possible. 
The soundtrack should perfectly complement what is happening on the screen, otherwise, users have an obsessive desire to close, forget, and prefer truly qualitative options. History of sound accompaniment for slot machines
Many perceive pleasant music and even the most banal sounds of slot machine reels spinning, such as on the website https://onlinecasinos.com.ua/igrovyie-avtomatyi-777.htm as something quite ordinary, without delving into the process that preceded such a breakthrough.
The first truly impressive achievements came in this field when in regular slot machines like Space Invaders, background music began to play in 1978. Before this moment, slot machine sounds played only in the opening and closing screens. The gameplay itself was occasionally accompanied by some short signals, as it required using a whole chain of transistors, resistors, and capacitors with a very complex tuning process. Slot machines simply did not have the necessary power to entertain with multiple processes simultaneously. Only after 1980, systems with special chips responsible solely for sounds and not affecting the performance of central processors came into use.
One-armed bandits
Naturally, this technology reached the slots we are all familiar with a little later. Various, so-called, one-armed bandits pleased with a bit more serious abundance of motifs – the potential was growing, but the developers often used recognizable samples as the main set for spinning, winning designation, and so on. Only in the last years of the legal existence of gaming pavilions could one enjoy the most technologically advanced solutions, which already had their own plots, melodies, and sound schemes, but even this lasted quite briefly. Modern slots
This is where modern virtual slot machines come into play. The beauty is that by the time casinos were banned, design in this field was quite developed, and a lot more skilled people appeared than in the ’80s.
As a result, the world quickly saw virtual modifications of familiar games, which initially perfectly imitated familiar sounds, as well as the sound of coins and much more. Naturally, the development moved primarily towards individuality rather than imitation and nostalgia for the bygone era. It was here that there were more solutions with unique plots told through the backdrop, symbols, and melodies – no more cherries, bananas, bars, and such. Right now, there are a vast number of slots with a wide range of quality, but among them, there are definite leaders. For example, the company NetEnt strives to surprise gamblers not only with beautiful effects but also with the most thoughtful approach to sound.
Each element of their developments sounds as harmonious as possible, conveys the overall mood, creates an unusual atmosphere, and attracts. These slot machines are something you want to open every day again and again not only because there is a high payout or you like the design. When you start spinning the reels, real magic is created here from the combination of sound and effects, which may also lead to a significant win.
