If you like to play casino online slots on your smartphone, you’ll have experienced the definite pluses of playing on mobile casino sites. You don’t have to sit at a desk or balance a laptop on your knees, and you can play while waiting in a queue or during your lunch break. You’ll also know that it’s more comfortable handling your smartphone in portrait mode.

While most mobile casino slots still present in landscape format, we’ve put together a pick of what we consider to be the best online slots in the UK which have been optimised for play in portrait mode. Take a look!

Ecuador Gold

ELK Studios is the developer of Ecuador Gold, a thrilling 6-reel slot with a return to player (RTP) ratio of 96.1% which has been designed specifically for you to enjoy in both portrait and landscape modes. Set in a Mayan temple, you are an adventurer who’s searching for treasure. As you’d expect from a game set in a South American temple, players are presented with such symbols as suns, temples, masks and exotic animals. The intrepid explorer also features as the highest-value symbol in the game.

When it comes to gameplay, you have more than 4,096 ways to win with each spin! But where this slot shines is with its thrilling Avalanche feature. When this game mode triggers and you land a win, the symbols explode and new symbols appear, giving you an even greater chance to match symbols and claim a prize. But that’s not all – as you win, additional rows are added to the reels, peaking at an incredible 262,144 ways to win!

If you’re in the mood for a beautifully animated slot adventure through an ancient part of history with a mysterious soundtrack to match, you need to look no further than this mobile slot.

Jurassic Giants

In Jurassic Giants, the creatures that roamed the prehistoric jungles of the Jurassic era make an impressive showing in portrait mode in this exciting slot from developer Pragmatic Play.This 6-reel, 4-payline slot gives you 4,096 ways to win as the formidable T-Rex battles the mighty mammoth and fearless sabre-tooth tiger.  

The 6 reels are larger than many other slots and, because the traditional paylines have been replaced by an all-ways-to-win set-up, it’s easier to spot matching symbols right away. Any winning combinations simply have to appear in neighbouring columns, so you don’t have to consider where specific symbols have to land.

The game is suited to both larger and smaller bankrolls, with a minimum bet of 50p, a maximum bet of €250 and a RTP of 96%. If you’re a fan of the Jurassic Park film series, you’ll undoubtedly enjoy the thrills of this mobile slot at our no deposit casino. 

Chi

Next on our list of portrait slot games is Chi, developed by Elk Studios. This beautifully designed title centres around the characters of two fox-like creatures called Chi (representing “fire”) and Mow (“wind”). Artistically rendered Himalayan mountains and natural scenery form the backdrop against which Chi and Mow set out to find a lost city of treasures. This title’s reel set-up of cylindrical wheels that spin laterally presents particularly well in portrait mode.

This is a 5×3 slot with 27 paylines paying both from left to right and right to left, which gives you 54 paylines in total. Chi has a high-volatility RTP of 96%, which means that wins may not happen as often as in other slots but when they do happen, they’re fairly generous! And since you can play across devices from 20p, this is undoubtedly a slot to keep an eye on.

Sweet Bonanza

The game Sweet Bonanza presents an explosion of colourful sweet treats, and plays just as well in portrait as in landscape mode. The 6-reel mobile casino slot from Pragmatic Play uses a tumbling-reels game engine for extra action. During bonus rounds which reward lucky players with 10 free spins, multipliers can increase payouts by up to 100x their stake, potentially leading to some big wins. Bets range from 20p–€125 a spin. 

Indulge yourself in a world of fruit, cakes, and candies and hope you land some winning combinations. Each time you do, the Tumble feature is activated: the reels tumble, the winning combos are removed from play and new symbols replace them. Sweet Bonanza is a medium- to high-volatility slot with an RTP of 96%.

Esqueleto Explosivo

The last of our featured portrait slot games is Esqueleto Explosivo. The graphics in this video slot, powered by Thunderkick, draw inspiration from the Mexican Day of the Dead, and the soundtrack plays along with a snippet of a Mexican song whenever you land a winning combination.

All five of the title’s symbols are skulls, each representing a member of a musical band. Features include the Explosivo Wild (the yellow skull can substitute all the other symbols and, once hit, explodes the eight surrounding symbols, which increases a multiplier by one level); the Mucho multiplier (which is triggered if you hit a win or land at least one Explosivo Wild – levels increase x1, x2, x4, x8, x16 and x32), and Dropping symbols (similar to cascading symbols but which explode if you land a winning combination, after which they are replaced by symbols that drop down).

The 5×3 slot has an available betting range from €0.01 to €100 and 17 paylines. A low- to medium-volatility slot with an RTP of 97.6%, it is likely to offer small but fairly frequent wins.
