Types of Games You’ll Find in a Slot Website

As you’ve probably noticed, the amount of slot games you’ll find online is becoming significant. Even though most operators license products from a few providers, their iGaming collections often include hundreds of titles. To make things easy, you can roughly divide virtual slots into four categories.

Classic Slots

These slots have a 3-reel and 3-row outline akin to the traditional machines of the good old days. The well-known fruit, bar, 7, and diamond symbols are also a staple in this category.

While exceptions exist, 3-reelers don’t usually pack fancy features like elaborate bonus mechanics, a large number of paylines, or scatters. This simplicity is perfect if you’re new to slots or just prefer a time-honored experience. Make sure you’re playing games with an RTP rate of 94% or above.

Video Slots

This group is super expansive. It includes every 5-reel, 3-row slot, which is an industry-standard. However, machines with 6 or 7 reels, different rows, and paylines are also considered video slots.

Various wild symbol types, free spins, bonus mini-games, and all the latest bells and whistles you can imagine can be found in such titles. Video slots can be a bit overwhelming to the uninitiated, but most modern players love the novelty and excitement they bring.

Jackpot Slots

Technically, every slot has a jackpot, as that is the word used to describe the highest reward it offers. However, there are different kinds of top prizes:

Cascading Reels and Floating Symbols

Among the tens of thousands of online one-armed bandits, there are a few that dare to break the typical spinning reel paradigm. The most popular slot games of this kind have cascading reels.

The mechanic is similar to Tetris – when you align winning symbols, they disappear and allow new ones to fill the void. This series of events can create a huge combo payout if you’re lucky. Try NetEnt’s “Asgardian Stones” to see just how good that feeling can be. RTG’s “Cubee” is another stereotype-breaker. There, you can form combinations between 3-8 orbiting symbols while fighting with monsters for a reward of up to x50,000 your bet.

The bonuses at the Best Online Slots Sites

If you’re an avid slot player, you should always check out the promo page of your chosen casino. Most gambling sites in the US offer many incentives that you can utilize to your advantage. No deposit deals, welcome packages, deposit matches. There are even perks that add free spins. They can extend your gameplay and give you a better chance of hitting the jackpot!

For example, at 888casino, you can get $20 in promo funds for just registering. Use them to try some of the most popular slot games and see if you can turn them into cash. After that, the house will match your first deposit up to $500.

In 99% of the time, slot machines are the best games to play to fulfill bonus T&Cs. They contribute the entire value of your wagers to the playthrough requirements. Other casino games either provide a fraction of your bets or don’t count at all.

Slot Basics – Know the Fundamentals

Place a bet, spin the reels, and hope for a big payout. The most alluring aspect of these gaming machines is that they are that easy to play. Once you register and deposit at online slot sites, the only thing left to do is to pick a title and press a button to get going.

However, what many new players don’t understand is that there are ways to increase their odds of winning. Below, we will analyze every core element of these games. If you’re not experienced, do yourself a favor and study the paragraphs. Being informed is always beneficial for your bank account.

Payment Symbols

Payment symbols are the core of every slot game. Most often, you have to align at least three of them in a payline (see below/JL to payline) for a chance to win real money. If you line up four or five, the prize increases. Every slot symbol has a different value, and you can always check the help/info section to see how much they pay. Their visual appearance can differ greatly from game to game to fit a particular theme.

Most modern slot games also feature wilds and scatters. These are special symbols that players love to see on the reels. Wilds can take the shape of any regular symbol to aid you in forming a winning combination. Developers love to use different mechanics for wilds. You can see them expanding across the reels, sticking for several spins, and so on.

Scatters don’t need to appear in a particular order. Usually, if you see three or more of them when the reels stop spinning, you’ll enter a bonus round. It could involve free spins, invoke extra features, or even trigger a mini game.

Payouts, Bets, and Paylines

A quick examination of a game’s paytable can tell you what you can expect to win. Hitting 3-5 symbols in a line gives you a reward. It’s a multiple of your bet that changes depending on the winning combination.

Slots give you the option of adjusting the size of your wagers. One important thing to remember is that higher bets can increase your chances of winning something big. For example, some progressive jackpot titles need you to bet a certain amount to qualify for winning the grand prize. However, when you have more skin in the game, the potential to incur a higher net loss per session also increases.

Pay lines is another aspect you have to mind. Some machines have a fixed number that is always active. Others have adjustable ones that you can turn on with your money. If you’re on a budget, a good tip is to activate all pay lines, even with the smallest of bets. They increase your chances of getting a winning combination, which is a better alternative than putting all your eggs in one basket.

Bonus Rounds

At slot machine sites, you’ll find releases that include bonus rounds. These features come in many different shapes and add an extra level of excitement to your experience. More often than not, bonus rounds give gamblers the highest chance of winning big money.

How a bonus round is activated depends on what title you choose to play. In some games, it’s completely random. Others can grant you various perks as you advance through the story. The third (and most common) option is scatters.

Getting an X amount of free spins is what you can usually expect. When you enter that mode, you can benefit from new wild symbols, score higher wager multipliers, and even add more free spins. It all depends on the developer’s imagination. The bonus rounds of some slots include a “match the pictures” game or a wheel with random prizes. You can always get information on them by scrolling through the paytable.

So Many Themes to Choose From

Do you have a favorite movie, musician, superhero, holiday, heck, even a historical period? Chances are that there’s a reel game themed after them. This segment of the market is huge and super competitive.

There are hundreds of developers that are regularly churning out products. The best slot machine websites are the platform where you can find the top offerings. While historical and holiday themes can be enjoyed virtually everywhere, intellectual property is usually exclusively licensed to a certain developer. For example, if you want to play Batman- or Superman-themed slots, you have to find a casino that offers Playtech games.
