By Since many years ago, slot machines have become an important part of the global gambling industry, tempting players crazy with their easy to understand game rules and generous bonuses. The popularity of slot machines is rapidly spreading, and nowadays, their presence can be found on almost all online gambling platforms.
Classification of slot machines
In both the online and real world of gambling, you often see two main types of slot machines: video slot machines and classic slot machines.
Video slot machine games
Video slot machines are one of the most popular gambling devices in online and offline casinos. They have a rich variety of themes, allowing developers to add various dynamic effects without relying on mechanical devices.
Classic slot machine
Classic slot machines have some slight differences from video slot machines; They belong to earlier game genres and usually only have one, three, or five payment lines. The symbols are usually fruits, bells, bars, and the number “7”.
The operation mode of slot machines
Whether in a physical casino or online platform, the operation of slot machines relies on various technical support. Although you don’t need to delve into its internal mechanisms, understanding the underlying principles may be helpful to you. Next, let’s unveil the mystery of slot machines!
Random number generator
The randomness of each rotation is controlled by a random number generator (RNG). This is a sophisticated computer program that can quickly generate numerical sequences. Its design purpose is to ensure that every result is random, thereby preventing game developers from exploiting this vulnerability to cheat. Therefore, RNG needs to be certified by authoritative testing institutions before it can be used.
Payment line
The payment line is a pre-set line on the slot machine turntable. When the corresponding symbol falls on this line, you can win the corresponding bonus; If three consecutive lines with the same symbol appear on inactive payment lines, the prize cannot be won. Most video slot machines have multiple payment lines, while classic slot machines usually only have three.
Symbol
The turntable of the slot machine displays various symbols. Each symbol has a specific value, and based on the number and position of symbols you receive, you will receive corresponding rewards according to the game’s odds table. The common symbols in classic slot machines include fruits, numbers, and letters, while the common symbols in video slot machines are mostly theme related symbols. Some slot machines are also equipped with special symbols, such as versatile symbols and scatter symbols, which can trigger reward functions and increase your chances of winning in basic games.
RTP and Volatility
The player return rate (RTP) is a percentage used to measure the proportion of money expected to be paid to players in a slot machine over the long term. Generally speaking, it is recommended that you avoid slot machines with RTP below 90% as much as possible.
Volatility represents the level of risk associated with slot machines. For example, high variance slot machines may bring generous bonuses, but this situation is relatively rare. On the contrary, low variance slot machines often offer bonuses, but the amount is relatively small.
Slot machines and the gambling industry
The popularity of slot machines has had a profound impact on the entire gambling industry. Slot machines are not only the main source of income for many casinos, but also play a positive role in economic development.
The economic contribution of slot machines to the gambling industry
Slot machines have provided a huge driving force for the economic development of the gambling industry, both online and offline. However, the profits created by slot machines are far more than just casino profits. The existence of taxation enables the revenue from slot machines to be used to support local economies, such as healthcare, education, and public infrastructure construction.
