Casino Online Slots Themes

No matter which casino games that are free online the theme plays an integral part. Everything about the free online slots from its special features, its rules to its visual fidelity pivots around the theme. It can be a fantasy, horror, racing, or Western theme. On the whole, a slot machine’s theme is the sugar that helps the medicine go down.

Consequently, it’s easier to represent real, or otherworldly new slot machine game topics with HD visuals. Themes in video slots also apply to mainstream appeal. So, if the Soccer World Cup is on the go. Online slots studios for real money release slot machine’s with soccer themes before the World Cup starts. There are slots online gamblers who think themes in slot games are not important.

We beg to differ though. Slots developers like Betsoft take the psychological effects; the mechanics and wrap them into something familiar. In other words, something online slot machine gamblers can relate to.

 

Casino Slot Machine Symbols

The symbols in free online slots go hand in hand with their theme. Take an online slot machine game like RealTime Gaming’s Cash Bandits 3 for example. We know that it is a heist theme.

What about the slots symbols that appear on the reels? You’ll see bags of cash, a wad of dollar bills, the bandit, and the police car. The bottom line is the slot symbols on the reels complement the casino online slot’s theme.

Moreover, the symbols in the Cash Bandit 3 slot machine are low and high-value symbols. In addition to the online casino slot symbols, you’ll see the robber Wild, and the Scatters. When 5 high-value symbols pitch on the reels in slot games. Their payouts range from 5x up to 500x your stake.

Important Slots Symbols

Wilds: The wild symbol is the Robber. The wild’s sole duty is to form a winning combination when it substitutes symbols adjacent to it. It can be low or symbols of high-value. There are different types of wilds in online slot machines. There are Walking or Shifting Wilds, Expanding Wilds, and Sticky Wilds.

Walking Wild: Walking Wilds move from left to right or vice versa across the reels. As they move, they form winning new combinations in slots until they drop off the reels.

Expanding Wild: When an expanding wild appears it covers an entire reel for the big wins. The size of the expanding wild can be 2×2 or 3×3.

Sticky Wild: When a sticky wild pops up, and as it names implies. It sticks to the reels of the slot machine game for the duration of one or more spins.

Scatters: In online slot machines the scatter symbol is often the ‘unsung’ hero. Because it seldom offers a payout. Slots players tend to ignore scatters to a degree. However, there are games slots machines that offer scatter pays for 3 or more scatters. Moreover, 3, 4, 5, or 6 scatter symbols trigger the Free Spins feature.

The free spins slot machine players receive are proportionate to the scatters. For example, 3 scatters award 10 free spins. Four scatters give 15 free spins and 5 scatters 20 free spins. The nice thing about the scatters in slot machine games; they re-trigger the free spins feature for extra free spins.

The problem is players seldom follow the instructions in the slots online’s paytable. As a result, people play the slots ‘blindly’, please don’t do that! You’ll find all the info about the slots in its Paytable.

 

Top Online Slot Machine Jackpots

Slot machine designers like RealTime Gaming, Microgaming, and Net Entertainment. Divide their free online slots to play into non-progressive and progressive slots. A non-progressive slot machine’s jackpot never grows.

Online casinos offer sign-on bonuses to play the best slots online with real money. If you accept the bonus please read the bonus terms carefully.

 

Which Jackpot Slots To Play Real Money?

It belongs to Microgaming’s ever-popular progressive jackpots slot network. Furthermore, hundreds of Microgaming Casinos offer Mega Moolah. At that, the size of Mega Moolah’s slot jackpot reaches epic proportions. Mega Moolah paid out millions of dollars recently.

In 2019, Mega Moolah slot players won an incredible sum of $79 million. And, in 2020 a lucky Canadian online casino slots player won CAD$16 million.

Low, Medium and High Variance Slots

Win real money slot machine vendors like Yggdrasil and Red Tiger Gaming divide their slots into low, medium, and high variance.

Thus, each online slots caters to bankrolls of different sizes. Casual slot machine players will play low or medium variance slots because they want to take things easy. While high roller casino VIPs will dive straight into slot machines that are high variance. High variance slot machines have bigger jackpots to the tune of tens of thousands or millions of dollars.

Another characteristic of low variance slot games is that they offer frequent winning spins. They have high hit ratios of up to 40 percent. So, low variance online slot players will receive a winning spin on every 2nd or 3rd spin. The payouts range from 0.2x to 0.5x your stake. As you can see they’re small. Furthermore, low variance slot games offer jackpots of up to $50,000.

Medium variance slot games on the other hand are in between. They offer a winning spin on every 3 to 4 spins and their jackpot sizes aren’t too shabby.

 

Mobile Slot Machine Compatibility

The online casino slots industry continues to move towards the mobile phone direction. Mobile casino slots providers update their software to incorporate the Z-generation. Millennials no longer see the need for gambling from their desktop. As such, they want to play slots online on their phones! Sadly, gaming from desktop computers could very well be a thing of the past.

Online slots players want to play casino games that simulate AR and VR environments. As technology becomes less expensive it’s the future of the online slots industry. Moreover, thanks to 5G internet connections it makes gaming more fun and accessible!

Slot games load faster than ever before on iOS, Android, and Tablet devices. Mobile phone slots players can play the slots for free now. Data bundles are cheaper than ever before. As such, it opens up a whole new slot machine world at the tip of their fingers.

 

Is It Safe To Play Slot Games Online?

Yes, absolutely. Independent testing companies such as eCOGRA, TST, and iTech Labs test the RNGs of slot machines online casinos offer you. They offer you random winning spins. And the built-in RTPs to the house ensure continued fair play.

 

Special Features In Online Slots

The more special features an online slot machine has the better. It makes the game more fun to play, and they offer big payouts when you trigger them.

There are exceptions to the rule. But, for the most part, the Free Spins features contain the jackpots of slot machines. This also explains why it is so difficult to trigger the free spin bonus rounds of certain slot games online. Depending on the online slot game’s volatility. You can trigger the Free Spins feature within 25 up to 500 spins.

 

Free Spins With Multipliers

When we play slots at online casinos. We check if the slot game has a Free Spins feature. Preferably a slot machine online with big multipliers because the payouts can be mint! Now, a slot game that is all the rave is Gonzo’s Quest Megaways Slots.

How so? Firstly, it is a Megaways slot with a Cascading system. Secondly, the slot game online has incredible graphics and pin-dropping audio that draws you in right away. Thirdly, it has a Free Spins feature with progressive win multipliers of up to 15x!

 

Re-spins

The next thing to Free Spins are slots with re-spins. You can trigger a slot online machine’s free spins feature on any random spin in the base game. As long as you hit a winning combination. You’ll keep on getting re-spins.

 

Cascades or Avalanche Features

When you land a winning combination of 5 to 6 symbols. The Avalanche features remove the winning symbols from the reels.

Moreover, winning symbols drop in from the top to replaces them. Hence, it is possible to snag a few chain wins on your original spin. The most chain wins we had in a slot machine was 5.
Pick Me Options

When you trigger a slot game with a Pick Me bonus round a new screen opens up with treasure chests. If there are 15 chests you must pick on7 or more of them. Every chest offers you an instant cash prize and their values combine for one big payout. The bonus round ends once you made all your picks and you’ll return to the base game.

 

Bonus Buy Feature

We’re seeing tons of new slot machines with a Buy or Bonus Buy Option. Now, the British Gambling Commission is not a fan of the Buy Options. The Commission believes it encourages problem gamblers to spend more money. We don’t necessarily agree with them but that’s the way they see it and we respect that.

So, what is the Buy Option and how does it work? The Buy Option cuts out the base game. And, it allows you to trigger the Free Spins immediately. There is a slight catch though. If you use the BuyFeature it costs anything from 50x up to 750x your stake. An online slot with a Buy Feature is Nolimit City’s Deadwood.

 

Bonus Wheel

Slot machines also have a Bonus Wheel that you can trigger on a random spin.

The Bonus Wheel contains big multipliers, Free Spins, and cash prizes. As you spin the Bonus Wheel, and wherever the marker lands. You’ll win a cash prize or free spins. Moreover, you can trigger the Bonus Wheel with 3 or more scatters.

 

Megaways Slots

Megaways slots are highly innovative slot machines online with a groundbreaking math model.

So, what makes a Megaways™ slot so special? The fun starts with a six-reel set up along with a horizontal reel that contains 4 symbols. On each spin, 2 to 7 symbols can pitch on the reels. The gist of the Megaways slots is that it gives you a stupendous amount of winning combinations. Interestingly, they change constantly.

But, more importantly, the number of possible Megaways™ can go up to 117,649 win ways on a single spin. The net result is plenty of winning spins.

Slots With Infinity Reels

The online slots machine industry constantly evolves and reinvents itself. As real money slots, developers marry and incorporate new elements into their slot machines.

What are Infinity Reels? When you land new winning combinations you can add an infinite amount of new reels. In other words, the slot game keeps on adding new reels to the right.

If you’re lucky, you can add up to 30 new reels in one round for a massive payout. It’s highly unlikely, but it indicates the possibility. That is the short and sweet end of it at least. Odin Infinity Reels is another top example of such an innovation.

  • Slot games with infinity reels are highly volatile.
  • They offer huge jackpots of up to 25,000x your stake.
  • Offer Cascades, therefore you can score plenty of winning spins from your original spin.

With the newest innovation in online slot machines. It’s evident that they are breaking out of their niche corners. We’re seeing Megaways slots and now lately, slot machines with Infinity Reels for a fully immersive experience.

Low-speed Internet connections kept mobile casino slots players out the loop for a while. Luckily it’s no longer the case, because of the advent of 5G for mobile devices. Smartphones will be much faster and laggy slot games a thing of the past. We’ll see big budgets, big teams, and slot games with increasingly realistic graphics.
