Variety is key to anything in life, and online slotting is no different, which is why there are so many different themes to choose from. We all have our personal favourites, but amongst the most popular genres of online slots are those that feature jewels and gems. This could be because you may class it as a fairly generic theme that’s easy to understand or that we all tend to associate those colourful and sparkling stones as being incredibly expensive and valuable. Whichever camp you happen to fall into, you can get better acquainted with the games in this niche here on our dedicated page, where you’ll find the highest paying RTP slots it has to offer, slot demos, reviews, and the titles that provide the biggest jackpots.

Our Conclusion: As someone who has spent much time happily spinning away on Sweet Bonanza in the past, it was immediately clear to me that Bonanza Gold was essentially the same game but with a different skin on. However, I think that the designers have done really well here. The graphics are impressive, the music is complementary, and the theme is well delivered. This is a solid game, and I have minimal complaints. My main suggestion for improvement is the addition of a persistent multiplier during the free spins bonus, as that would elevate player excitement levels and the game itself to the next level.

Our Conclusion: The Gems Bonanza slot can seem quite a complex game when you first look at it, but once you've had a few spins, you will soon realise that it's easy to follow and understand. In some ways, it reminds me of the grid slot Reactoonz, but I think that is due to the number of base game modifiers that can eventually lead to a bonus trigger.As for the main feature, I bought several bonuses in testing and sometimes struggled to get past level 2. Ultimately, in this slot, you will need to progress to level 3 or more to see the full potential of this game. Overall, I found the game fun to play, and it's an excellent addition to the grid slot niche, so make sure you take our Gems Bonanza free play version for a good few spins to see what it has to offer.

Our Conclusion:
Gemix is great fun and is bound to appeal to fans of mobile puzzle games such as Candy Crush. If you don’t like the theme, perhaps take a look at Viking Runecraft instead – that is a virtual clone of Gemix, using all of the same mechanics, but with a theme that is likely to be much more appealing to male players. If it wasn’t for games such as Gemix, grid slots may never have become a subgenre of online slots in their own right – and if you like these games as much as I do, that would certainly be a bad thing. Recommended!

Our Conclusion:
The Da Vinci Diamonds online slot has been around for several years now, and it remains a firm favourite with many players. Despite its lower-than-average RTP rate when compared with other slots, it has high-quality graphics to offer, as well as an intriguing free spins round to trigger. Tumbling reels will also always be appreciated in any online slot, and IGT has done a great job incorporating them into this release. This one will surely be enjoyed by many players in the years to come.

Our Conclusion:
Bonanza Megaways is quite possibly the best online slot ever to be created. Not only was it the first of its kind in the Megaways series, but it would go on to inspire hundreds of new games that featured the combo of an unlimited win multiplier and cascading reels. Such was the success of Bonanza that Big Time Gaming even added their Megapays Jackpot Engine to it, so players could enjoy all the thrills they had experienced before, but with Bonanza Megapays, they now had the chance to win a life-changing amount of money, too. To conclude, Bonanza Megaways is rated so highly at Demoslot that it is currently the only slot ever to receive the MAX WIN rating and a perfect score of 10. Simply put, this is a sensational slot that every player must try at least once.
If you have fallen in love with this game like so many players in the past, BTG has added more games to the series, although not as good as the original, in our opinion. Intrigued to find out more? Then try out Bonaza Megapays and the unique Bonanza Falls.
FAQ's
Not at all. You’ll find many variations of these games offering different in-game mechanics and modifiers that mix in with other themes, such as mining slots and classic slots.
Jewels and Gems are among the most used themes by game providers, and across all iGaming providers, you can expect to see ten or more new slots with this theme released each week.
Although each player will differ, we think that jewels and gems games that include the Megaways mechanic or are part of a grid slot provide the most entertainment.
