Diamond Fiesta Slot Review

In 4,900 spins, I spent $2,450 at Diamond Fiesta slot and… lost $248.75. Overall, it’s a 90% return. Sounds bad, right? It’s a lot more complicated than that. I also grabbed a Minor jackpot, em… worth $15. Well, all I want to say about the online casino slot from RealTime Gaming software (RTG for short), including the final verdict, is in my review below.

Diamond Fiesta 2021 💥 $326 Loss vs $500 (Possible) Win in 6.5K Spins

Diamond Fiesta Streams Review

Okay. First thing you’re going to need is a slot description. Diamond Fiesta has the basic structure – 5×3 reels, which in total give 50 (fifty) winning lines. The key difference is in the features, in which, at first reels, then symbols can expand up to 8×4 (see the screen above!).

Expanding Reels feature is a true game changer! You’ll discover more about it in the Jackpot Diamond bonus review. There’s also a chance to get 3 Respins, 6 Free Games along with Mini, Minor, Major & Grand rewards in the Diamond Jackpot Bonus! It seems like a good slot machine.

So, what can go wrong? Let’s look into the numbers. I played this video slot for a month and lost $248.75 overall. My bet on every spin was $0.50. If I bet $12.5, it would result in thousands of dollars in losses ($2,487.5, actually). By my calculations, each spin is negative, and is -$0.05 in fact. Also I had good times and made some money. For better understanding of this game, here are outcomes of 3 different sessions.

How to Play Diamond Fiesta Slot for Real Money

Again, here I lost $248.75. So before trying the online slot for real cash yourself, you might be interested in details of my experience. So, I will just start.

Bet Limits & Jackpots Levels

You get to spend anywhere from $0.50 to $12.50 per spin. My stake was 50 cents, the lowest one here. To go down or up, you simply adjust the coin value from 1 to 25 cents on the left. The amount of paylines (50) is fixed and can’t be changed.

Slot Symbols

Diamond Fiesta Slot Paytable

Bonus – Diamond. It counts at any position. 6 ones open Diamond Jackpot bonus.

Scatter – Skull. 3, 4 and 5 Skull images pay 2x, 5x, and 100x respectively. And scatter symbols provide access to a Free Games round.

Wild – Senor Skeleton that helps create winning lines. The Señor can appear anywhere but the first reel. All wild symbols substitute for regular icons except for the scatters (Skull) and bonus images (Diamond). Regular ones are playing cards from 9 to A, Lady, Chili Paper, Maracas, and Tequila, if you’re interested.

Jackpot Diamond Feature

Diamond Jackpot Respin Feature

I had a lot of fun playing it. It’s my favourite feature. First you need to get 6 or more Diamonds anywhere on the reels. From my experience, it happens quite frequently. Sometimes I got the bonus icons three times in a row during a single set of 100 spins. After you get them, you receive 3 Re-Spins with all Diamonds held in the position. The feature of Diamonds is known as Sticky Wilds. At the very end, each Diamond value is revealed. The payouts differ based on the slot grid:

  • Diamond and 4 Jackpots – 1x-50x your bet ($0.50-$625)
  • Diamonds and Major + Grand Jackpots (8×4 layout only) – 3x-250x your bet ($1.50-$3,125)

Jackpot Diamond Expanding Reels

Diamond Jackpot Feature

Whenever Diamond images (bonus symbols) emerge in 4 corners, the win potential grows. The reels expand and symbols are added. You begin with 5×3, then proceed to 6×3 and 6×4, and end up with 8 reels and 4 rows (8×4). So, in 4,900 spins, I got it to the max size a couple of times. My biggest catch here was $50.50. That includes a Minor jackpot of $15.

Free Spins Feature

Diamond Fiesta Free Spins

The moment the three Skulls skatter on the reels, you get 6 Free Games. In addition, you get extra Skeletons, Skulls and Diamonds. I got here between $3 and $10 on average. Not the best amount. well, I won $27 once. However, on a regular spin, I had $43.75 for 5 of a kind combination of Lady icons.

Design Overview

Diamond Fiesta – a jackpot slot with a Mexican theme from the Realtime Gaming company. The basis for the game was the Day of Dead holiday, originally celebrated in Mexico. So there would be loads of theme symbols and interesting animations. In terms of the graphical display and overall vibe, it’s something similar to The Mariachi 5 online slot, which follows the same theme.

My Verdict

Diamond Jackpot bonus adds a lot of excitement to the slot. 6 Free Spins aren’t hard to get either. But low-medium volatility and wager limits might not provide enough excitement for high rollers and slot streamers. During long playing sessions, I found it a bit boring.

On the other hand, small but frequent payouts make it more approachable for people who don’t like to take much risks. If you don’t know what volatility actually is, you’ll find the explanation here. I guess that’s it. Below I answer 3 most frequent questions about the game. You’re welcome.


  • Can I play it on mobile device?
  • Sure! I launched Diamond Fiesta on iPhone and iPad, but it can be played instantly on any other smartphone. Happy spinning!
  • What are key features of Diamond Fiesta slo machine?
  • Diamond Fiesta – 5 reel 50 line slot that offers 6 Free Spins, 3+ Re-Spins and 4 Diamond Jackpots. Due to Expanding Reels and Sticky Wilds, you can get truly good wins. That’s not my case though.
  • Where can I test it out for free?
  • You can certainly have a few spins at the online slot for free at any RTG casino including Fair Go. Alternatively, you can find a free mode and get a feel of the gameplay on third party websites. But there’s nothing quite like a real play. That’s why, you’re welcome to read my Diamond Fiesta slot review based on real life experience.
