Mobile-Friendly slotsOne of the ways most gambling enthusiasts choose to spend their time is by spinning the reels, and there are good reasons for this. Slots are visually appealing, offer enthralling gameplay, and include lots of extras that boost players’ chances of securing handsome wins.

The changes in the slot-making technology have led to the creation of a wide variety of titles that can suit every taste, and mobile slots are undoubtedly the ones making the greatest impact. Games of this type are so sought-after simply because, thanks to them, players can shake off all shackles regarding when and where to enjoy their favourite titles.

Currently, the lion’s share of software providers are focused on designing mobile-first slots, which is only natural, considering that an ever-increasing number of players choose to ditch their computers in favour of portable devices. There is much more to mobile slots, and they are not popular merely because of the greater convenience of play they provide.

In this article, we will leave no stone unturned regarding mobile slots and will provide brief descriptions of some worthwhile games.

Where Is the Difference Between Mobile and Desktop Slots

Players who are still not sure whether to make the leap to mobile slots should consider the differences between the experience offered when spinning the reels on their computer and on their handheld device. Something essential to point out is that while some slots work equally well on computers and portable devices, there are also titles that are designed exclusively with mobile or desktop users in mind. For this reason, players are advised to check the compatibility of their preferred game in advance to ensure they do not end up disappointed.

First and foremost, the greatest difference between desktop and mobile slots is that with the latter, players can enjoy the spinning action at any time and in any place. This is not the case with desktop slots, and gambling enthusiasts will be chained to their computer each time they wish to engage in their favourite games. In fact, opting for mobile-optimised games is also players’ best option if they are eager to take part in slots tournaments anytime and anywhere.

The ultimate freedom reel spinners enjoy when they opt for mobile slots is not the only advantage: such games are also a cut above their desktop counterparts in terms of bonus features, load times and visuals—something that would not have been possible without the great leap in technology.

One of the reasons why some players tend to frown upon mobile slots is that, on some occasions, the data signal can be patchy, which can negatively affect their overall experience. The chances of this happening while playing on a computer are significantly smaller, which makes many players prefer desktops over their mobile counterparts. Still, this occurs rather rarely and slot buffs should not lose sleep over it.

Reel spinners place great importance on usability, and for this reason, the difference in the screen sizes of desktop and portable devices should also be taken into account. For some slot buffs, the smaller screen size of tablets and smartphones is a shortcoming because they think they will struggle with their bets or the gameplay, which cannot be further from the truth. The animations are just as fluid and the graphics retain the same crystal-clear quality when players load their preferred games on a tablet or smartphone; therefore, the quality of the visuals or the smoothness of the gameplay is certainly not something to worry about.

Finally, slot fans should remember to keep their charger close at hand, as their tablet or phone battery will drain faster than normal.

Mobile Friendly slots vs desktop slots

Features Mobile Slots Have

Mobile slots are all the rage not only because they are convenient to play but also because they offer an array of features designed to make players’ betting sessions on the move trouble-free and enjoyable. Something players should be mindful of when they are up against a slot that works equally well on desktop and portable devices is that loading the game on a handheld device might sometimes mean seeing a slightly simplified interface.

Normally, mobile slots do not disappoint when it comes to their user-friendliness, as the lack of it can easily become a deal-breaker. Most software developers focused on the creation of mobile-optimised slots do their utmost to ensure that players can place their bets and enjoy the gameplay without any hassle.

To this end, the game controls should be conveniently positioned and large enough to ensure that reel spinners can open the paytable, select autoplay if such a mode is available, or adjust the game settings without any hassle.

While choosing a mobile slot to enjoy, players are advised to check whether the game supports landscape and portrait modes or just one of them. Presently, most game-making studios equip their slots with both modes in order to ensure it is easier for players to enjoy the titles that tickle their fancy most.

OS Mobile Slots Work Best On

Mobile slots are without doubt the best bet for gambling enthusiasts who are heavily into such games but hardly ever have enough time to place their bets at home. It is likely that some players might ask themselves whether they will be able to get the most out of their reel adventures on their tablet or smartphone.

Fortunately for players, most software developers these days seek to provide the best of both worlds and, to this end, base their games on the HTML5 platform. In essence, its introduction has had a major impact on cross-compatibility simply because this technology made it possible for a number of features to be carried over to portable devices.

This innovative technology has turned the casino industry upside down and led to the gradual demise of flash slots. Thanks to it, present-day slots work like a charm across tablets and smartphones that run Android and iOS, thus guaranteeing that players will not miss out on the features, visuals or gameplay, irrespective of the chosen device.

Thanks to this novel technology, players might easily feel that the characters in the playing area are about to jump out of the screen. The same technology is also used in fruit-inspired slots, which means that reel spinners will not miss the experience or the authenticity of such games when they access them on the move.

While revelling in slots on your computer is indeed enjoyable, spinning the reels on your portable device is a far more immersive and engaging experience. Play is effortless, and the best thing is that customising your gameplay normally takes just a few taps, no matter the device’s operating system.

The quality of the gaming experience remains the same across all devices, and the only distinction stems from the difference in screen sizes. What reel spinners should bear in mind is that present-day slots are built to adjust to all screen sizes right off, without affecting the quality of their experience.

Of course, gambling enthusiasts should not be left under the impression that the age of their device is of no importance to the quality of gameplay. One issue players might encounter if they have a rather ancient phone is lag in the gameplay caused by the device’s lower processing power.

Play’n GO

Play'n GOSpeaking about the heavy-hitters among the creators of gaming content that pay special attention to mobile slots, we should certainly mention Play’n GO. In fact, this is one of the very first software developers to get mobile play right, and its slots work without a glitch on iOS- and Android-based devices. To achieve this, the tight-knit team relies on the HTML5 platform, which makes it possible to transfer the thrill and excitement their games offer from desktop to portable devices seamlessly.

Accessing their creations on the go does not mean that reel spinners will lose out on the available features, which explains why their slots are among the most well-liked.

Yggdrasil

YggdrasilAlthough Yggdrasil is yet to gain the experience of the above-mentioned creators of gaming content, its mobile-friendly slots are indeed its claim to fame. The team has given its best to ensure that all games they roll out will work smoothly, no matter whether players decide to spin the reels on the move or via their computer. The company is dedicated to releasing at least one new slot each month, and the best thing is that all its creations are mobile-first.

Betsoft

Mobile Slots to Look out for in 2021

Narcos

NarcosOffering action-packed gameplay, Narcos is a NetEnt-powered slot that looks and feels just as good on desktop and portable devices. Obviously, the game-making studio has drawn inspiration from the Colombian TV series of the same name and has used comic-book visuals to enhance its appeal.

Narcos spreads across five reels and three rows, and wins can be achieved in 243 ways. While placing their bets on the move, players can choose stake levels that range between $0.20 and $200, which turns this mafia-inspired slot into a perfect fit for all types of players.

As you power up the game on your tablet or smartphone, you will find yourself on the Colombian streets where you will meet members of the drug cartel. NetEnt is indeed one of the software developers that have a flair for the creation of slots, and this is easily seen in Narcos and its special features in particular. When players want to enjoy some spinning action on the move, their betting session will be spiced up by four bonus games that can help their balance soar.

The free spins feature is one of the extras players may look forward to, as it awards ten bonus rounds in a row. Triggering the free spins feature means that players can collect handsome wins thanks to the walking wilds. The locked-up feature is no less attention-grabbing, as it gives three re-spins, and players will receive prizes that range between 1x and 10x the staked amount. Besides, players should always look for the appearance of the golden locked-up symbol because, along with the cash prizes it awards, reel spinners will also benefit from multipliers, upgrade symbols and the big starting value.

The walking wild feature might give mobile players better chances of scoring winning combos, as this symbol moves across the play area until it reaches the first reel. Lastly, there is the drive-by feature, which can begin at random; when this happens, a gunman appears and starts firing. If a bullet strikes any of the premium-paying icons that have landed on the reels, it will turn into a wild one.

Reel spinners can start enjoying the action after they adjust their bets between $0.10 and $500, and, once they are ready, they just need to tap the spin button to see what rewards the game has in store. Kingdoms Rise: Chasm of Fear is certainly not a middle-of-the-road slot, as its reel set expands from 1,024 in the main game to 3,456 in bonus rounds, thus giving players significantly more opportunities to land a win.

As they load the game, players will find themselves on a pirate ship that floats on crystal-clear waters. The detailed graphics and fluid animations are indeed appealing, but the real charm of this slot stems from the bounty of rewarding special features it is equipped with.

The Kingdoms Rise jackpot feature is undoubtedly the highlight of this video slot because, thanks to it, reel spinners can grab the Epic, Power Strike or Daily Strike jackpots. The free spins feature might be rather straightforward, but it should not be overlooked, as while it lasts, the ways to win are boosted to their maximum. At the onset of the bonus game, players are awarded six bonus rounds, but the best thing is that their number can grow infinitely.

Slot buffs can also take advantage of a re-spin feature, which starts when a scatter symbol pops up on the fifth reel. When this happens, the reel set expands and a re-spin is awarded.

As players engage with this mobile-friendly slot, the most substantial prize they can grab is 25,000x the chosen bet level.

The rousing soundtrack, meanwhile, will enhance the experience and make the betting session more immersive. The symbols that appear on the reels are anything but ordinary, and so are the extras of this adventure-based slot.

The Temple Free Spin Feature begins when players see three to five scatter icons, and getting enough of them will bring between eight and 12 free rounds. These bonus rounds are played using a special machine that has six reels and three rows, and thanks to it, slot buffs will get between eight and 15 re-spins. Collecting seven lamp wilds during the bonus spins gives players access to the Secret Treasure Bonus feature, during which they can collect a cash prize or receive a multiplier.

The Oasis Free Spins feature launches when reel spinners manage to collect 25 oasis icons. Activating this bonus feature means that players will receive ten free rounds in a row, during which the appearance of waterfall wilds awards wild reels.

Its paylines are fixed at ten, while its play area comprises three rows and five reels. Players do not need a big bankroll to engage with this video slot, as the stake limits range between $0.10 and $100. As for its RTP, it is above the average, standing at 96.14%, which applies to most Thunderkick-powered slots.

This video slot is nicely designed, and the visuals retain their high quality when players give it a shot on their tablet or smartphone. Not to mention that the clean and crisp game interface is just as effective on portable devices as it is on computers.

When players head over to this star-filled galaxy, they should always look out for the bonus features that might come their way on every spin. The top payout a betting session can produce is 2,500x the staked amount, which is certainly not among the most whopping prizes available.

The special features of Cosmic Voyager are not as plentiful as players might wish, as the expanding symbol feature and the bonus game are the only ones to take centre stage. The expanding symbol feature starts when three stacked symbols land together on the left-most reel. When winning combos are formed with these symbols, the rest of the winning icons turn into expanding ones, thus offering more handsome wins. The golden mask is the icon that can deliver the most substantial prizes.

Mobile users are offered a bundle of ten free rounds when three wild or scatter icons land together, thus activating the other bonus feature of this video slot.
