While the exterior of a slot machine appears as a simple animated object, filled with flashing lights and fun sounds when the button is pressed, it is actually governed by complex mathematics and an intricate game design. This guide provides the reader with a clear understanding of how slot machines work (from the player's perspective) by explaining the concept of Random Numbers Generators (RNGs) without using technical terms or convoluted theories.
Modern slot machines all use RNGs, which are programs that generate thousands of random number combinations every second, even when no players are using the machine. When you press the Spin button, the slot machine will capture the most recently generated number and use it to calculate the outcome (symbol placement, and either a winning or losing result).
Since the RNG generates its numbers randomly, there can be no pattern or predictable timeframe, making it impossible to develop any kind of strategy to play. The idea that some machines are "Hot" or "Cold" is a myth; the outcome of every spin is determined based purely on randomness.
All slot machines have pay tables that outline the requirements of winning combinations and the amount that each winning combination pays. They provide the player with both the requirements for forming winning combinations and the payout amounts associated with those combinations. There are three general categories of symbols in a slot machine:
All the symbols and payouts for the specific combination of symbols are predetermined prior to the release of the game. Therefore, there is no advantage for any one player over another, other than chance.
The RTP of the game represents the theoretical amount of money that you can expect to win back from the game, in the long run, i.e. the amount of money you can expect to win back from betting in the game. For example, an RTP of 96% means that, over time, for every $100 wagered on the game, you would expect to be returned $96.
A player's results will greatly differ based on the randomness of the game.
The volatility of a slot indicates the level of risk associated with the game.
The decision on which type of slot to play is based on what a player wants from the machine. Do they want to play steadily? Or do they want to gamble for more excitement with a higher level of risk?
There are multiple types of slots available, and the type you play will depend on what your intention is for playing: casual play or larger payouts.
Classic slots are the original slot machines. They continue to be straightforward in design and include a few traditional features. Classic slots include: 1-5 payout lines; simple and uncomplicated odds; very few (if any) other bonus features; these types of machines offer quick & easy play.
Video Slots are now more entertaining than ever before with their advanced graphics, animations, and soundtracks. Many of these Video Slot Games also have:
All Video Slot games aim for immersive experiences and interactive storytelling.
Progressive Jackpot Slots donate part of every bet made by players into a central pool of funds. The Progressive Jackpot will keep growing until it is won by a player who meets the requirements to win (randomly or by hitting a specific combination). There are many stories of players hitting Mega Moolah for enormous sums (over $13 million), and while the potential payout is high, the likelihood of hitting the Progressive Jackpot is low.
Megaways Slots have a dynamic reel structure that constantly alters how many symbols can appear per spin, allowing for tens of thousands (most start out at 117,649) of different winning combinations. Instead of using fixed paylines, players can win by matching symbols directly on adjacent reels from left to right.
Cluster payouts slots reward players for matching groups of adjacent symbols, rather than matching symbols in lines. Winning clusters typically trigger Aeration effects (new symbols falling in) during that same spin and possibly lead to additional wins. The icons of many of these games feature vibrant imagery and character themes that are very popular.
Slot machines are now built using advanced technology that's revolutionizing how the way we play slots with technology that can create cross-device compatibility (HTML5), immersive 3D gaming experiences (Unity) and proprietary engines developed by companies like NetEnt and Microgaming.
The use of cloud computing has allowed for fast, real-time processing of game play so that players can have an uninterrupted gaming experience. JavaScript and WebGL are used to create an engaging visual environment and interactive graphics.
Slots have transitioned from mechanical devices to fully functional digital gaming systems that are designed to provide reliability and performance.
There is a great deal of regulation about the way that slots operate and how players are treated. In addition to meeting specific requirements set forth by the Malta Gaming Authority and the UK Gambling Commission, licensed developers of slot machines must conduct independent testing of the RNG systems used to determine the results of a player's gaming session and provide verification that the RTP to players is accurate. Additionally, licensed developers of slot machines must have programs in place to protect players from gambling and self-exclusion tools.
Since regulations regarding gambling vary from one country to another, players should research their local laws to ensure compliance prior to participating in online gaming.
Slots are designed to create a high level of player engagement with multi-sensory stimulation, including lights and sounds, in addition to the use of near-miss outcomes to invoke the brain's reward system. Many small wins may create a perception that there is progress and that the player is getting better, despite losses overall.
In addition, because the current design gives players the ability to play at an accelerated rate - i.e., by playing hundreds of spins in an hour using autoplay - there is an increased risk of developing problem gambling behaviour associated with faster-paced games when compared to other types of gaming (e.g., table games).
To ensure that players do not lose sight of their limits, it is important for them to treat slots as a form of entertainment only.
Although slot outcomes are random, using responsible habits when playing slots can help to enhance the player's overall enjoyment of their experience:
In the U.S., casinos receive a large percentage of their revenues from slot machines, due to the high amount of play per machine, and the relatively small average amounts wagered on each machine. Globally, the online slot machine industry is expanding due to the ongoing introduction of new games and the availability of gaming via mobile devices.
Despite increased revenues, concerns exist regarding the potential for gambling addiction and the financial harm that may occur to vulnerable populations. To achieve long-term sustainable growth for the casino industry, we must maintain an appropriate balance between profitability and responsible gaming.
Continued innovation is constantly changing the slot machine gaming industry.
With the advancement of technology, new game formats will continue to be added to the slot machine industry as digital entertainment continues to increase.
Slot machines are games of chance based on probability and regulation. Understanding how a slot machine works allows the player to view it as a source of entertainment, rather than an expectation of they will win money.
