In this Diamond Fiesta slot review, I’m going to be giving you an in-depth look at this exciting new RTG slot on mobile.

Today, you’ll learn about the best mobile slots sites to play at, how the game works, how to play (and win), and what to expect when you play Diamond Fiesta for yourself.

You’ll find that Diamond Fiesta looks great, is easy to play and has some fantastic win potential. So let’s dive straight in and take a closer look.

Realtime Gaming is a well-known game developer who tends to focus primarily on the North American market, although in recent years they’ve started to penetrate other markets.

Diamond Fiesta is a 5-reel, 3-row video slot with a total of 50 paylines. Unlike some of Realtime Gaming’s earlier releases, you don’t have the ability to change the number of paylines active on each spin (something that I was quite surprised about), although the game is well-suited for those playing on a variety of budgets as you can spin from between .50 and 250 credits per spin.

I’m actually quite familiar with Realtime Gaming’s slots, and I’ve long been a fan of one of their early releases, Mariachi 5. I found that Diamond Fiesta contains many similarities with The Mariachi 5, and it follows a Mexican/Spanish theme, with funky, upbeat music accompanying every spin.

How To Play

Like all of Realtime Gaming’s slots, Diamond Fiesta is built around a relatively easy-to-use and well-laid-out format and it’s pretty easy to select your bet size and begin spinning! Unlike other game developers (NetEnt and Microgaming being two good examples), Realtime Gaming opt to keep things simple, and there’s a simple “Bet Per Line” adjustment option you can scroll through to find your ideal bet.

This means you don’t need to worry about having to choose a coin value and number of coins – a complication that causes many new players to get confused when it comes to choosing their bet size.

I also like that the vast majority of Realtime Gaming’s slots still offer you the ability to “slam stop” their reels – or quickspin manually, by clicking the Spin button during the spin. This is well-suited to players who’re looking to play a greater number of rounds per minute. Realtime Gaming have actually built in a “quick spin” mode too, and this can be toggled on/off by pressing the lightning bolt icon, found just to the right-hand-side of the main Spin button.

If you want to read the game’s full rules or view the pay table, you simply need to press the hamburger menu on the far right-hand-side of the screen.

There’s also an autoplay button which allows you to set up to 1,000 spins to play-out automatically. This is a great feature and it enables you to pre-set a large number of spins to play out automatically without you needing to manually press the spin button on each spin.

Symbols and Payouts

Before I get into looking at the specific symbols and payouts of Diamond Fiesta I want to point out that the game’s RTP is fixed in place at 96%. However, you should always double check the RTP of any slot you’re playing, as there are occasions where an online casino will be able to offer a lower RTP version of the slot.

Like many game developers, Realtime Gaming tends to use playing card values in their games to depict the lower-paying symbols. This includes the likes of 9, 10, Jack, Queen, King and Ace.

The symbols you’ll really want to be keeping an eye out for are the Mariachi Band Members as these are the higher-paying symbols. It will probably come as no surprise to learn that the playing card value symbols pay very small amounts of money – especially as there’s only five reels – so the real big wins are formed by forming 4-of-a-kind or 5-of-a-kind combos of the top-paying symbols.

The highest-value symbol can even dish out big wins by making a 3-of-a-kind combo, so you’ll want to keep an eye on this!

I should also point out that Diamond Fiesta uses Skeleton Wilds, but these aren’t just wild symbols; they also play a role in triggering the main bonus round, details of which I’ll cover in the following section of this post.

Bonus Features

I was pleased, while playing Diamond Fiesta, to find out that there’s a couple of bonuses around, although the secondary bonus (the jackpot round) is triggered through the first feature.

In the following section of this Diamond Fiesta review I’m going to be taking a look at the two different bonuses you’ll find in the game – and I’ll explain how to trigger the bonuses, and what you can expect when you manage to activate them!

Free Spins

As I mentioned in the “Symbols and Payouts” section of this review, the wild symbols don’t just act as wild symbols; they also are the key to triggering the Free Spins feature.

Landing three or more of these scatter symbols in any position on the reels and you’ll trigger the Free Spins bonus. You will then find yourself awarded with (at least) 6 free-spins, and before the spins play out, additional wilds are added to the reels. You’ll also notice that new special diamond bonus symbols are added to the reels, and it’s these diamonds you’ll want to pay close attention to.

During the free-spins, each time one of the diamonds lands in view you’ll be awarded a free free-spins. The diamond symbols then act as sticky wilds, and lock in place for the re-spin. If, on the re-spin, you land any additional diamonds on the reels they will also lock in place and a further re-spin will be awarded.

This continues until you either fill the screen with diamonds or until you fail to land any new symbols in view on the reels. You will then be paid out the respective win, and the next free spin will then begin. (The re-spins don’t take up your remaining free-spins, so this is something worth bearing in mind.)

Now, if you do manage to land a diamond symbol in all four corners of the screen you’ll actually expand the reels up to a 8×4 reel set. This is where the major money is made, as it’s then possible to make 8-of-a-kind combos, awarding significantly bigger payouts!

Finally, I should also point out that it is possible to re-trigger more free-spins. This is achieved by landing another three or more of the skull wild scatter symbols anywhere in view, and doing so will award you with an extra 6 free-spins. Like many Realtime Gaming slots there is no limit to the number of times you can re-trigger the free-spins feature; there’s a (potentially) unlimited number of free-spins up for grabs!

Jackpot and How To Win

Compared to some of Realtime Gaming’s other slots, Diamond Fiesta may not offer the largest win-potential I’ve ever come across, and it turns out that the maximum win on each individual spin is 800X; not enough to make you rich, for sure, but enough to keep the vast majority of players happy.

However, I should point out that this 800X maximum win is actually the max win per spin during the free-spins feature – so, theoretically, it’s possible to win 800X your stake on more than one occasion during the bonus.

Diamond Fiesta big jackpot win

When it comes to winning, unlike some other Realtime Gaming slots (which have progressive jackpots built in) there’s no impact on the RTP depending on the stake size you’re playing at.

This means that “upping” your stake size doesn’t change the chances of you winning – and if you’re looking for how to win, unfortunately, the only “real” way to improve your chances of hitting a big win is to give the slot a fair try; I’d recommend giving it at least 2-300 spins, as the bonus round can be quite hard to trigger.

However, from my own personal experience playing Diamond Fiesta, the bonus does typically tend to pay quite well, so it’s often well-worth waiting for.


Diamond Fiesta slot logo Realtime Gaming were one of the latest iGaming developers to “adapt” their games for mobile devices – and while, in the past, playing their slots from mobile devices was a bit of a pain, today it’s a much smoother experience.

When I was putting this review of Diamond Fiesta together, I did my best to try playing it from as many mobile devices as possible.

I was pleased to see it rendered great on my Android phone and my Apple tablet, and there’s no extra software required to start playing – simply open the game up from your mobile device’s internet browser and you’re all set! No complaints here.


Diamond Fiesta may not be the most well-known slot on the planet but if you’re a fan of Realtime Gaming’s games – or want to try something new – it’s a game I can definitely recommend. I like the bonus round – it’s fun, and offers up some decent win-potential – and there’s also some fairly decent base-game hits available too, so for me, it ticks all the right boxes!
