Introduction to Extra Gems

Extra Gems is a gem-themed online slot from Platipus with a tribal twist and a very unusual layout. You get six vertical reels, three rows high, plus a horizontal reel running across the top. That setup creates a variable number of ways to win, from 2,304 right up to 21,609 on a good spin. On top of that sit cascades, split symbols, multipliers and free spins, so the grid hardly ever feels static.

As a player, I like that Extra Gems keeps things simple on the surface while hiding a lot of depth in the mechanics. It is a high-volatility slot with a stated maximum win of around 5,005 times your stake, so the game can feel swingy. When the win multiplier climbs and the split symbols open up thousands of extra ways, though, the whole thing comes alive in a very satisfying way.

Extra Gems Theme, Graphics & Soundtrack

Extra Gems uses a colourful tribal gems theme that feels inspired by Aztec or Mayan temples. Stonework frames the reels, while every symbol is a polished jewel or bright card suit, and the animations give the slot a vivid, almost arcade feel. A slow, rhythmic soundtrack sits in the background, then ramps up whenever cascades and multipliers start to chain together, which suits the high-energy gameplay rather nicely.

Extra Gems RTP and Variance

On the numbers side, Extra Gems runs with a theoretical return to player of about 95 percent, which is a touch below the current 96 percent benchmark I see on many modern slots. That does stand out if you care about long-term odds. Combined with high variance, it means the game tends to hold onto your bankroll for stretches before paying out bigger hits in short, sharp bursts.

In practice, my Extra Gems sessions have swung quite hard. With stakes starting from around twenty pence a spin and going up to about twenty pounds, there is room for cautious play as well as more aggressive staking. I have had runs where the balance dripped away for ten minutes, then a single free spins round, helped by a chunky multiplier, wiped out most of the damage.

How to Play Extra Gems

Getting started with Extra Gems is straightforward. I set my bet with the coin stack control, then open the paytable through the menu button in the corner to check what each gem can do. Sound settings sit right there as well, which I like. From there you can choose manual spins with the main button or switch on autoplay if you prefer to let the game run.

Because Extra Gems is high variance, I always set a clear budget and session length before I start. The game flows fast once cascades and split symbols begin to land, so it helps to pause now and then, especially after a big win or a draining spell. If your casino offers timeouts or self-exclusion tools, it is worth using them when you feel the need.

Extra Gems Bet Sizes & Paytable Wins

The paytable in Extra Gems carries twelve symbols in total, ten regular and two special. Low pays are the classic card suits, while the premiums are differently coloured gems, topped by a rich green stone that can pay from only two of a kind. The special symbols are the golden mask wild, which appears only on the horizontal reel, and the blue diamond scatter that triggers free spins.

In terms of raw numbers, that green gem sits at the top of the table and can reach payoffs around 500 times your line stake when stacked across the reels. The yellow gem follows with prizes up to about 80, then the pink diamond with up to 50. All wins pay left to right on adjacent reels, and the official maximum win across the grid is around 5,000 times your total bet.

From a player’s point of view, the paytable in Extra Gems feels well balanced for a high-variance slot. Small cascades of suit symbols keep the balance ticking over between the bigger gem hits. What really matters, though, is seeing wild masks land on the top reel at the right time, or lining up those premium greens with split symbols to push the number of winning ways as high as possible.

Extra Gems Bonus Features

Extra Gems comes alive through its bonus mechanics rather than a separate side game. Every winning combination triggers a cascade, removing the winning symbols and dropping new ones in from above. Each successful cascade also increases a global win multiplier by one. That multiplier resets between paid spins in the base game, but during free spins it carries over, which is where the serious potential lies.

Free spins themselves are triggered by landing three to six blue diamond scatters anywhere on the main reels in one sequence, awarding between nine and twenty-seven spins. Extra scatters during the round add two more spins each. Alongside that, the split symbol feature can double matching icons when they line up with the symbol on the horizontal reel, so it is possible to rack up tens of thousands of ways on a hot bonus.

Overall Extra Gems Review

Overall, Extra Gems feels like an enjoyable online slot with a couple of clear strengths and a few quirks you need to accept. The visuals and audio are high quality, the split symbols and multipliers create a satisfying gameplay loop, and the flexible number of ways keeps spins varied. On the flip side, the subpar RTP and sometimes slow-to-trigger free spins mean it will suit patient players more than bonus hunters.
