Diamond Mystery 50 Extreme Hot - Review, Demo Play, Payout, Free Spins & Bonuses

Introduction 

Get involved with a digital version of a classic format in this Greentube free slot that takes its inspiration from traditional fruit machines. This 5x4 online slot with 50 paylines comes with all the bonus features you would expect from a contemporary slot game such as wilds, scatters and a free spins bonus. The live progressive jackpot is what makes this online slot appealing, with continuous sounds ringing to let you know that other live players are winning the jackpots.

For this reason, it is rare to find it available as a free slot, so make the most of your opportunity here at Slots Temple! For a full breakdown of the game, read on for our full Diamond Mystery 50 Extreme Hot slot review.

Theme, Graphics & Soundtrack 

Taking all of its inspiration from classic fruit machines, there’s plenty of recognisable symbols here, from fruits and diamonds to 7s and bells. There’s no attempt to style this like a land-based slot, however: instead there's a digital and quite practical-looking screen layout that makes it easy to follow along but does little to add visual interest. The lady joker wild goes some way to adding some character, but otherwise this is an online slot for purists looking to focus on the game at hand.

If you’re looking for something a little more thematically playful, check out the Money Train 2 slot from Relax Gaming. But if a distraction-free focus on jackpots is your game, read on for all the details on this digital fruit machine.

Diamond Mystery 50 Extreme Hot RTP and Variance

We estimate an RTP of 96%, meaning it sits at about average for contemporary online slot games. Be warned this appears in ranges, so check the RTP of any online casino offering the game. The variance in play testing appeared to be high, with long waits between wins but the chance for jackpots when they do randomly appear.

How to Play Diamond Mystery 50 Extreme Hot

If this is your first time or you need a refresher, our slot review can show you how to get started with a free slot like this:

1. All game controls as well as remaining balance info and current bet level are along the bottom of the screen.
2. The menu button to the left will give you paytable and game rule information. 
3. Use the + and - buttons to adjust the bet level according to your budget. 
4. Autoplay and turbo mode are both on/off toggles. Be warned, this means autoplay starts immediately once clicked and offers no win or loss limits, so you’ll need to monitor these yourself.
5. The start button will spin once and can make it easier to monitor your own play.
6. Enjoy free slot games responsibly by creating a budget, even when using virtual money, and sticking to it. Slots Temple offers time-out and self-exclusion functions to help keep gaming fun.

Diamond Mystery 50 Extreme Hot Bonus Features 

While nothing revolutionary, this is still a good selection of bonuses that adds to the base game:

Wilds 

The lady joker wild can appear anywhere on the reels and will substitute for other paying symbols to help create winning combinations. These often appear stacked and can cover a whole reel for extra chances. The wild is also the highest-paying symbol when it forms win lines with itself. 

Scatters and Free Spins

The star scatter symbol doesn’t pay out but does offer free spins. Land them anywhere on the reels and match the following numbers for free games:

3 scatters = 10 free spins
4 scatters = 20 free spins
5 scatters = 30 free spins

Progressive Jackpots

These are triggered randomly during gameplay and involve picking face-down cards to get matching pictures. Find three matches to trigger one of the four progressive jackpots above the main reels. These are continuously adjusting in line with other live players, making this an interesting feature to find in a free slot. 

Diamond Mystery 50 Extreme Hot Review: Our Verdict 

Our slot review found nothing especially new or different about this choice of online slot games from Greentube. The graphic design is a little dated compared to many recently released slots, and the high volatility may put off newer or more cautious players. That being said, it ticks all the boxes in terms of core mechanics and may appeal to players looking for a no-frills experience.
