Online Slots Mechanics Explained - Reels, Paylines, Wilds, Scatters and Bonus Features
Playing a slot sounds like an easy task. Just open a game, click on spin, and get the outcome. Either the round will pay you, or you move to the next spin. But things under the hood are not that simple.
What happens on your screen is actually the final step of a much bigger system. A reel or grid structure, symbols with various values, rules for determining which combinations win, and unique elements that may change the outcome of a spin or bonus round, all these are parts of the game.
This is where the popular terms like paylines, ways to win, wilds, scatters, free spins, multipliers, and cascading reels come into the picture.
To get the best slot gaming experience, you won't have to know the inner mechanics of the game. But it's important to have a basic understanding of these terms.
Once you know these, the options on the game screen won’t be that confusing for you. Moreover, you will have a clear picture of which features are there just to make the game look good and which ones can actually twist your winnings.
How Do Online Slots Work?
Popular online slots try to replicate the behaviour and entertainment factor of slots in real casinos. However, they are engineered a bit differently. When you play on platforms like Raja567, online slots use a programmed set of rules to determine the outcome of each spin.
These slot machines use a regulated system powered by a random number generator. RNGs produce random outcomes, and the results are then mapped to the relevant game outcome. So, the reels or the combinations you see on screen are not independently deciding what to display when you press the spin button. It's all managed by certified RNGs.
If you pick a basic slot available after your Raja567 Login, there might be three reels and a couple of symbols. On the other hand, a modern video slot will have five or six reels, several rows, hundreds or thousands of potential ways to form a win, plus free spins, wilds, multipliers, and changing reel configurations.
No doubt the rules around every game on Raja567 can be different, but the basic building blocks remain surprisingly consistent.
What Are Reels in an Online Slot?
When you open an online slot game after completing your Raja567 login guide, you will definitely notice some vertical columns on the machine that spin and stop to display slot symbols. These are reels in an online slot machine.
For traditional slot games, including Mega Joker, Irish Gold, and more, you can expect a three-reel setup. However, for modern slot games such as Starburst and Gonzo’s Quest, and more, there are usually five reels used.
One fact is that the number of rows in a slot machine is not constant. The developers can play with the number to build different types of winning systems and level up the fun.
What Are Paylines in Online Slots?
If you play online slot games, it becomes necessary to know that paylines form the framework of the game. Paylines are simply the lines where the symbols drop on the reels of a slot machine. Paylines can be horizontal, vertical, and even diagonal.
Classic slots usually have one payline. But to increase the fun and the possibility of bigger prizes, video slots have many, even thousands, of paylines.
The fixed payline is the oldest and still the most popular one. It is a predetermined path across the reels that the game checks for matching symbols along, typically from left to right.
One payline may pass across the centre row of a traditional three-reel machine. A modern video slot machine can include 20, 25, or 40 paylines, some of which can be zigzagging instead of straight, all active at once and checked each spin separately.
Wild Symbols
Wild symbols are substitutes for other symbols. They come into the reels to help finish a combination. Suppose two matching fruit symbols land on the reels alongside a wild. The wild symbol will take up the place of the third fruit symbol to complete the combination.
The simple job of wild symbols is substitution. You can consider them the same as jokers in cards.
Types of Wilds In Online Slots
In online slots, wild symbols come in different types, which are as follows:
Standard Wilds
A standard wild is a symbol that substitutes for one or more regular symbols. This mainly depends on the game rules.
It's the same as the previous example we gave you. Suppose there are two symbols and a wild. The wild will substitute to form the combination.
Expanding Wilds
A standard wild substitutes only one position. However, an expanding wild can grow beyond its original position. Sometimes expanding wilds can cover an entire reel.
The trigger for expanding wilds depends on the game. Some activate expanding wilds during free spins, while you may be able to use others in the base game.
Sticky Wilds
In standard or expanding wilds, the wild symbol disappears after a spin. But that's not the case with sticky wild symbols. As the name says, these wild symbols remain in place for additional spins instead of disappearing immediately. Typically, you get sticky wild symbols during free spin rounds.
Walking or Moving Wilds
A walking wild symbol moves across the reels. However, this depends on the rules of the game, and these symbols can sometimes remain active for several spins before leaving the playing spot.
Multiplier Wilds
Some wild symbols come with multipliers. When these wilds contribute to the winning combination, the math changes. Depending on the game rules, the relevant payout can be multiplied.
What Are Scatter Symbols?
Scatters do a different job than wild symbols. Wild symbols create a winning payline combination. However, scatter symbols operate independently of paylines.
Normally, scatter symbols trigger a special feature based on how many there are on the payline, irrespective of reels, rows, or paylines. Mostly, slots make use of scatter symbols to start bonus games.
We can say the main use of these symbols is triggering free spins. In games like Book of Dead, when three scatters land anywhere on the screen, the bonus round kicks off. Some slot games also pay a small amount for the scatters themselves once two or more land, separate from whatever they go on to trigger.
First of all, it should be noted that 'scatter symbol' and 'scatter pay' are two different definitions with common names. They cannot be considered identical because 'scatter pay' refers to a particular icon, while 'scatter symbol' denotes rules for placing matching icons.
What Are Bonus Features in Online Slots?
Bonus features are the extras of slot games. They make the games much more exciting and rewarding. Generally, bonuses sit on top of the base spin. In most slot games, these features are triggered by landing scatter symbols or any special type of symbol or by satisfying a pre-defined condition in the game.
Here are the bonus features you can expect in most slot machines online:
- Free spins: In online slot machines, this kind of bonus is the most common. In addition to locked-in symbols, multipliers, and extra wilds, you are granted a predetermined amount of free spins with special perks not present in the base game. In most games, you earn free spins through the use of scatters.
- Multipliers: You can get multipliers as bonus features. They sometimes come attached to a wild or printed on a token that drops in randomly. You can use a multiplier to multiply your payouts.
- Pick and Click Rounds: For pick-and-click games, you must unlock the reward by finding it in a hidden spot such as a box, a tomb, a card, or any other object within the game’s setting.
- Hold and Win: This bonus feature is a bit different. Apart from the locked symbols, multipliers, and additional wild symbols, you get a fixed number of free spins that have unique advantages different from those of the main game. In most cases, you get free spins using scatters.
What is the Bonus Buy Feature in Online Slots?
A bonus buy is just purchasing a bonus feature in a slot machine. Many games offer you a bonus buy button in their interface. By clicking on this button, you directly pay and enter a bonus round. There is no need to wait for triggering symbols to land on the reels and start the bonus round.
The bonus buy price is generally set as a multiple of your current bet, most often somewhere between 50x and 100x.
What Are Cascading or Tumble Reels?
Another popular term you will definitely hear in online slots is 'cascading' or 'tumble reels'. So, what's this? Cascading reels basically change what happens after a winning combination lands.
In the case of cascading reels, when a winning combination hits the reel, the spin does not just end. Rather, the winning symbols are removed, and new symbols drop to fill up those spaces. These new symbols can again create a winning combination.
How Do Wilds, Scatters and Bonus Features Work Together?
Now that you know what wilds, scatters, and bonus features are, it's important to understand how the real mechanics of slots work with these concepts.
Let's take an example of a five-reel slot to clarify.
When you play this type of slot machine, a regular symbol combination creates a base-game win. A wild drops beside those symbols and substitutes for one of them. This completes the combination.
Now let's suppose three scatters also drop during that spin. Here, the scatter won't be replacing the regular combination. Instead, they meet the game's bonus trigger and unlock a free-spin round.
During this free spins round, some wilds will turn sticky. A winning combination can then trigger a cascade. Here, new symbols may drop and form more winning combinations.
One of these wins may include a multiplier wild, and the winnings can be lucrative.
Do More Slot Features Mean Better Odds?
A big no. This is often a misconception among newbies. No doubt more features elevate the entertainment. But it can also increase the risk factor.
A slot can have expanding wilds, ten different bonus mechanics, and a huge ways-to-win number. But in reality, it may significantly fail to give better RTP.
These are just the cherries on top. It's the mechanics that determine how the game produces wins and features. So, to understand a game's actual profile, you should always check its RTP, volatility, paytable, and rules rather than looking into the bonus features list.
Choosing a Slot With This in Mind
Neither the symbols nor the bonus features will tell you the best slot to play. All these are just marketing gimmicks. Suppose you are someone who gets tempted seeing 117,649 ways to win in a Megaways game.
Remember, it's just describing its reel count, not promising how often it will pay.
So, how to choose a slot? The best way is to try the demo mode, if available. Play the game in demo mode to understand how wilds, scatters, and the bonus features work in the game before investing in real-money bets.
FAQs
Q1) Do more paylines mean better odds?
Ans: No, not necessarily. You can get a 40-payline slot and a 10-payline slot offering the same RTP. More lines don’t mean more payout. It just means more chances to register a small win per spin.
Q2) Can a wild land on top of a scatter?
Ans: No. They occupy the same grid positions, so a wild landing where a scatter would have counted as a wild for that spin, not both.
Q3) How is the bonus buy feature different from free spins?
Ans: You can trigger free spins in the base game by landing scatter symbols. You don’t have to pay anything for these. On the other hand, a bonus buy skips that step. There is an upfront price to get a bonus.
