Extra Gems - Review, Demo Play, Payout, Free Spins & Bonuses

Introduction 

Extra Gems is a gem-themed online slot game developed by Platipus. It offers a variable number of ways players might win, with up to 21,069 paylines available depending on the feature that might be triggered. In terms of reels, this game has six reels and three rows, with an additional reel across the top. It also offers split symbols, free spins and multipliers that this Extra Gems slot review will explain more about later on.

There are a total of 12 symbols in this slot game: ten of those are regular and two are special. Of the regular ten symbols, we see an assortment of differently coloured gem symbols along with the four classic playing card suits. Our two special symbols include the wild gold mask, which substitutes for all other symbols except for the scatter and appears only on the top horizontal reel. Our scatter symbol is a blue gem, and it can appear anywhere on the reels: it grants access to the free spins round.

Theme, Graphics & Soundtrack 

Extra Gems boasts a colourful tribal gems theme reminiscent of the Inca or Aztecs. We see beautiful tribal stonework in the background of the game, and the reels are adorned with treasures from ancient temples in the form of sparkling gems. In the background, a slow and rhythmic tribal beat thumps softly away in accompaniment, as well as the expected arcade-style sound effects as you spin the reels.

Extra Gems Bonus Features 

This slot review wouldn’t be complete without a look at the bonus features: there are free spins, multipliers and split symbols on offer. Free spins are triggered by landing three, four, five or six of the scatter symbols, which give 9, 15, 21, 27 free spins respectively. During the free spins, any further scatter will award two more free spins.

The multipliers are activated after a first win and begin at one. Any wins that come after this will increase the multiplier total by another one: this continues to build until no more winning combos are possible, at which point it will end and reset to one.

Finally, the split symbol feature. This is the one that can really bump up the number of possible ways to win. What happens is that if any vertical reel symbol matches the symbol above it in the horizontal reel, it will split in two to make more potential ways to win. If it is wild, then its entire row will split to make even more ways. 

Overall Extra Gems Review 

This Extra Gems online slot has been a fun slot review. We particularly liked the split symbols feature and enjoyed the multipliers. The rules were reasonably straightforward to understand and we loved the theme.

That said, we did think that it was a highly volatile game and noticed that the free spins feature required patience in waiting for it to trigger.
