5 of the best online casino games to play in 2021

As you begin to play online slots, you’ll notice there are so many types of themes and styles of game to choose from at our mobile casino.

We’ve aimed to cater for a wide variety of tastes in this selection, so we’ve included games with diverse themes, from falling gems and “luck of the Irish” landscapes, to Ancient Egypt and blazing volcanoes – we’ve covered a broad selection that we hope you’ll enjoy reading about (and playing).

1. Gems Bonanza by Pragmatic Play

Shiny, colourful gems are, of course, one of the classic slot themes, and Gems Bonanza is one of the most popular titles in this genre.

At first glance, you’ll notice all the differently shaped gems on the game’s 8×8-reel interface, which contrast with the dark, cavernous background: it might make you feel a bit like Indiana Jones on a quest for hidden treasure!

Features to look out for in Gems Bonanza include the Trigger Spin modifiers, which will help you land more winning combinations on the reels, and the Gold Fever Feature, which is activated once you win 114 points (by landing the right amount of exploding winning symbols). After this, you can keep progressing to higher levels by winning more points.

If you love your retro-feel slots, this one’s certainly worth a few spins.

2. Rainbow Riches Midnight Magic by Barcrest

The luck of the Irish is another popular theme in online gaming, and Rainbow Riches is a well-known game franchise that offers all of the leprechauns and pots of gold at the end of the rainbow that you might be looking for on the reels.

In Rainbow Riches Midnight Magic, however, instead of sunshine and green fields, you’ll be transported to a moonlit scene, and can experience all of the magic that comes with it.

If you thought that chasing rainbows by moonlight in this 5×3 reel game couldn’t be more magical, you can also choose to turn on the Super Dial, which will allow you to get some free spins when you land only 2 scatter symbols on the reels (instead of the usual 3). Also look out for the fairy on the reels during this bonus, as she’ll upgrade all picture symbols to the highest-paying one!

For those looking for even more instant-win entertainment with this theme, you can also try playing online scratch cards, such as Rainbow Wilds or Irish Eyes, on our site.

3. Power Strike Egyptian Riches by SG Digital

Ancient Egypt was full of abundant riches and extravagant treasures. You don’t have to excavate a pyramid to get your hands on some of the prizes in Power Strike Egyptian Riches, though!

On the 5×4 reels, you’ll find sacred animal symbols, as well as an ankh (an ancient symbol of life that looks like a cross but with a loop at the top), and a blue urn. As the name of this slot game suggests, one of its most important features is the Power Strike Bonus, which is activated when you land one or more scatter symbols on reels 1-4, and a Power Strike Bonus scatter symbol on reel 5.

Scatters in this game include the Prize scatter, which is a glowing blue orb, and the Free Spins scatter (which has the number of free spins you’ve won on it). You can’t mistake the Power Strike symbol, with its glowing orb background and text, but you won’t know whether you’ve won free spins, credits or one of the 4 fixed jackpot prizes until you’ve played the round! There’s nothing like a bit of the unknown to keep you guessing, right?

4. Roco Loco by Live 5 Gaming

Mexico’s Day of the Dead, or Día de Los Muertos, is an important annual occasion on which to honour your ancestors, and one that makes skulls look so much less scary!

If you’re fascinated by the macabre, but also enjoy a little lightheartedness, you can enjoy spinning the reels with games such as Roco Loco, which includes colourful skull faces (similar to the ones you might see in the 2017 movie Coco, with a similar upbeat soundtrack).

The key features in this 5×3 game include Stepping Wilds and Progressive Multiplier Free Spins. The Stepping Wilds will move down one position on the next paid spin, to help you land additional winning combinations, and a skull symbol with a pirate hat will award you some free spins when you land 3 or more on the reels, with all wins multiplied by the relevant progressive multiplier.

Stacked wilds and wild reels also keep things interesting, and players will find they enjoy the spectacular visuals in this imaginative slot game!

5. Queen of Embers by 1×2 Gaming

We said we’d provide a list of the hottest casino games, right? Well, you can’t get more “scorchio” than Queen of Embers, a 5×3 reel slot from 1×2 Gaming. All the fiery symbols on the reels add to the inferno, including crystals, fossils, flaming torches and volcanoes. The highest-paying symbol is the night sky symbol, which pays out 10x your stake if you land a combination of 5. There is also a roaring tiger wild symbol, and the Queen of Embers herself as the scatter.

Other highlights of this game include the 243 ways-to-win mechanic, which gives you so many different ways to win from left to right.

Bonus features include a free-spins round, which you can activate by landing 3, 4 or 5 of the scatter symbols, which will give you 8, 12 or 16 spins respectively. In this round, you can land even more goes if you get 3 or more of the scatter symbols, which will give you another 4, 6 or 8 extra moves. This bonus feature also allows for stacked wilds on reels 2, 3, 4 and 5.

Let’s hope the blazing queen and all of the other symbols bring red-hot qualities to your gameplay when you try this great new slot!
