Gambling on the Internet has changed a lot since the first online casino appeared in 1994. If initially the developers tried to transfer ground-based devices to the network, preserving their mechanics and features, now providers are creating completely unique games with a huge number of different themes, functions and operation parameters. Meanwhile, despite the variability of choice and the introduction of progressive mechanics, classic slots, the so-called one-armed bandits, continue to enjoy popularity.

How their prototypes came about

The first land-based slot machine , outwardly resembling slots familiar to our eyes, was developed by the American inventor Charles Fey. It received the sonorous name Liberty Bell, that is, the "Liberty Bell". Coming up with a name for his offspring, Charles wanted people to associate the device with the US struggle for independence from Britain. It was based on a mechanism with three drums, which were set in motion by a special lever. The simplest symbols were applied to them: fruits and cards. These images later migrated to other machines, including online slots.

Despite Fey's expectation of a warm reception for his development,slots soon fell into disrepute, because their rate of return was extremely low. Because of this, and also because of the presence of a lever in the mechanism, these devices began to be called one-armed bandits.

Later, when gambling began to be regulated at the legislative level, the percentage of return was increased. The design has also changed: the result was determined not by the mechanism, but by a computer element with a random number generator. However, the appearance of the machines has remained almost the same.

Features of classic slots

The main features that allow the slot machine to occupy a place in the classic category are its simple design and interface. Only standard symbols are used here: cards, fruits, bars. The control panel itself includes only a few buttons. With their help, you can select the cost of the spin, change the number of lines and start the rotation.

Other features of classic slots include:

• Small number of paylines. Usually no more than 10.
• Small field. The symbols are located on three reels, each of which places the same number of symbols . The field itself has a 3x3 format.
• The absence of complex functions. Payouts are mostly calculated in regular spins. Of the additional mechanics, a risk game or simple bonus rounds can be provided. Respins, free spins, stacked symbols and wilds are usually absent.

The main task of the classic slots user is to collect paid combinations. If identical symbols form a line, a payout will be due.

One of the most famous developers of classic slot machines in the CIS is the provider Igrosoft. This company offers more than a dozen slots based on their land-based counterparts.

Due to the small number of lines, the payouts when forming combinations are very noticeable. The prize money almost always covers the bet.
