While the mechanical aspects of reel spinning have advanced, the concepts of betting, spinning, and winning remain the same. Game creators use their imagination to blend different ideas when coming up with a unique theme for slots. While some creators stick to traditional reels, others have moved away from reels and developed Tetris-like slots.
Although changes are apparent, the main objective is to give players an opportunity to win. To understand various slot games, it is important to decipher their various features. Traditionally, players are required to match the symbols on an active payline. Sometimes, the game provides a choice to play on multiple paylines. Different slots have different rules for how symbols line up to form winning combinations.
How Online Slot Games Work
The random number generator (RNG) determines the outcome of every spin. The RNG selects a random number, and the slot game receives that number. The game then displays the corresponding outcome on the virtual reels. It is then the responsibility of the game to check whether the outcome of the spin results in a winning combination.
Paytables provide information on special features in online slot games, the symbols, what winning combinations look like, and how payouts are determined. The variety of ways in which combinations are formed and payouts are calculated makes it necessary to consult the paytable before playing a new game.
Different Types of Reel Layouts
Slots use reels and paylines in many different ways. Traditional machines often feature vertical reels, with symbols lined up to form winning combinations along paylines. These paylines can be straight or follow different patterns.
Some modern machines also feature alternative pay structures. For example, some may pay for groups of matching symbols that are next to each other, regardless of paylines.
There are also variations in how symbols are removed from the reels during a game. Cascading reels feature symbols that are removed from the reels when they form a winning combination and are replaced with new symbols. New symbols can then also form winning combinations. Depending on the game, this can continue for several stages.
Understanding Slot Symbols
Each symbol in a slot game has a specific job, and special symbols can add features to the game that are not available through standard combinations.
Wild symbols can replace certain standard symbols to help make winning combinations. There are many variations of wild symbols; some cover the entire reel, some appear as stacked wilds, others come with multipliers, and some wilds can even have additional features.
Scatter symbols usually do not have to appear on a specific payline to win. In fact, many games have bonus features that are activated by scatter symbols. Free spins are the most common example of a bonus feature triggered by scatters. Other symbols can also be used to activate bonus features, such as a wheel of fortune.
Special symbols can even lead to expanding reels or add multipliers to symbols. There are many differences in how special symbols work, even in games that look similar. It is always best to check the paytable to see what a symbol does, as well as which features a game offers.
Paylines, RTP and Volatility
Paylines are the lines used to identify winning combinations of symbols in slot games. A slot game can have multiple paylines, a single payline, or no paylines whatsoever (e.g., ways-to-win or cluster systems).
Another term commonly used in slot games is return to player (RTP) percentage. This percentage indicates the amount that a game is designed to return from wagers in the long run.
Using the example above, a slot game with an RTP of 96% is designed to return 96 units from every 100 units wagered, on average, over the long term. The return in any given session, however, can be very different from the long-term expectation.
The final term is volatility. This term defines the frequency and size of payouts in a game. Games with lower volatility usually have more, smaller payouts. Games with higher volatility generally have bigger, less frequent payouts.
Themes and Mobile Gaming
With the rise of mobile gaming, different configuration options have become available to slot developers to make their games compatible with smaller devices. Because of this, some slot features may vary between devices.
FUN88 is one of the online gaming operators where the games offered depend on the available content and the rules of the relevant jurisdiction. Therefore, players should check which games are available on their chosen devices and verify whether these offerings are permitted where they are located.
Understanding Random Outcomes
Some people believe that a slot game is due for a payout after a series of losing spins. While this is a common belief, slot games essentially produce random outcomes. Previous results do not influence future results in games with independent RNG-determined outcomes.
Likewise, the concept of a “hot” or “cold” machine does not hold water either. A series of winning spins does not affect future results, and a machine does not “go cold” after a series of wins. The same can be said for the belief that a win is “due” after a series of losing spins.
Summary
While online slots all share the idea of spinning reels, there is a lot of variety beyond that. Some games use paylines, while others use cluster wins. Special symbols are common, as are bonus rounds that change how wins are calculated.
There are a couple of key details that help explain how a particular game works. Knowing the rules and strategy, along with setting a clear spending limit, helps players make informed choices about their money and time.
