Slot Machine Themes

Slot machine games are the most popular attractions in any online casino.

This is partly due to how easy they are to play and to the vast range of game types and themes available for players to choose from.

For example, players can enjoy playing 3-reel classic games with just one or a small number of paylines.

Then there are 5-reel and more video slots that offer much more in the way of in-game bonus features, game mechanics, and ways to win.

Finally, there are jackpot slots offering the chance to win life-changing sums.

But that’s not all. Each of these game types comes in different variations and themes.

So, no matter where your interests lie, there’s bound to be a theme and games that you will enjoy.

But with so much to choose from, it can be hard to get started.

Here at bestslotsites.co.uk, we have taken a look at some of the most popular themes that you will come across for slots.

We’ve also picked out what we think are the best online slots for these themes.

So read on to find some great slots that you can play and enjoy.

Gem Slots

Gem-Themed Online Slot Game

Finding a gem-themed slot game to play is not a hard thing to do. A quick search will bring you an endless list of such games.

These cover the full range of game types from 3-reel classics to jackpot slots.

Many developers have created games that use diamonds, other gems, and jewels as the main icons.

Others feature a mix of stones such as diamonds, sapphires, rubies, and more.

Some games stick to one gem and have icons in different colours. Either way, players can enjoy the feeling of playing with opulent wealth.

Amidst the many gems slots available, we think Starburst is one of the best gem-themed slot games for gamblers to play.

Starburst Slot

This popular online slot game was created in 2012 by NetEnt.

The graphics hold up well today even though the game is relatively old.

This is a testament to how the game developers took their time in getting things right.

Set on a background of deep space, this game has a simple 5-reels and 3-row layout.

There are 10 fixed pay lines with a win both ways mechanic for players to win from.

The game offers a wide betting range, and wagers can be set by adjusting the bet levels and coin values.

The only bonus feature is an expanding wild that shows up on reels 2 to 4.

This feature becomes active if a player lands at least one wild symbol on those reels. The wild expands to turn the entire reel wild, and it locks in position.

A re-spin is also awarded. Should another wild symbol land during that re-spin, the whole process repeats to lock that new wild reel in place and award another re-spin.

Up to 3 re-spins are possible thereby filling the three central reels with wilds and increasing the player’s chance of landing some big wins.

Starburst also has an impressive Return to Player (RTP) rate of 96.09%.

This means that players can expect to win reasonably frequently and the game can be enjoyed like the true classic it is.

There really is not a lot to dislike about this classic that can be played and enjoyed today. More information can be found here.

Animal Slots

Animal-Themed Online Slot Game

For most people, animals are amazing creatures that tend to have our interest or at the very least our curiosity.

It should then come as no surprise that one of the most popular slot machine themes used by developers as the blueprint for their games is Animals.

The range of animals that can be used in a slot game is truly amazing, letting game developers create new and exciting slot games with this theme.

There is more than enough content to create a good animal-themed slot game from wild animals that can easily tear through bones to the cute furry ones we keep as pets at home.

One game that easily stands out in this theme is Wolf Gold.

Wolf Gold

From the creative minds at Pragmatic Play, Wolf Gold was launched in 2017 and brings with it a Native American theme for players to sink their teeth into.

The game takes animal slots to another level with hard to resist bonuses that range from Free Spins to Money Re-spin features as well as wilds, giant symbols, and scatters.

The reels are set on the backdrop of the grand canyon. There are royal symbols, wolves, mountain cats, stallions, buffaloes, and eagles.

The wolf is the wild and it can replace all other symbols except the moon and the scatter. It pays 1x, 10x, or 20x for 3, 4, or 5 in combination.

The game mechanics are straightforward and easy to grasp making this quality game a ton of fun to play.

Another cool feature is the full moon symbol, which will act as the money symbol.

If a player lands 6 of these symbols, it will then activate the Money Re-spin bonus feature. Users are then awarded 3 re-spins.

This feature continues until the reels are filled up with moons or if the player’s re-spins run out. Should all15 positions be filled up, lucky players will win the Jackpot.

The game has an RTP of 96.01% which is just above the industry average for an online slot.

Players can bet from as little as 25p to £125 per spin, thus catering to a range of players. For all the Wolf Gold information you want, click here.

Wild West Slots

Wild Wild West -Themed Online Slot Game

The great thing about Wild West-themed slots is how fun and easy to play they can be.

Throw in some outlaws here and there and even some Native American themes and soundtracks and players can easily get lost in that time.

Nothing beats playing as a gunslinger with no rules to hold you back, or you can explore the theme of being a lawman in a lawless land. Maybe it’s the Gold Rush that has your interest.

One thing’s for sure, there’s gold to be had if the luck is with you.

Game developers have used these different Wild West slot machine themes to great effect and created some stunning Wild West-themed slot games. One of the best is Mustang Gold.

During this round, the player also gains access to the Money Collect feature which adds extra Money and Collect Symbols onto the reels.

With 3 extra Scatter Symbols being hit and activated, players can then get 8 more free spins. This repeat triggering can go on for as long as possible.

Any player can trigger the Mini jackpot game by landing the Jackpot Money Symbol as well as the Collect Symbol. As a result, a new screen opens up to reveal 12 metallic horseshoes.

Once a player matches 3 or more similar symbols, the prize is revealed – 50x (Mini), 100x (Minor), 200x (Major), or 1000x (Grand).
