Extra Gems Game Details & Features
Platipus rolled out Extra Gems on 29.09.2022, and I've put in plenty of spins. It runs on six reels with the ExtraWays mechanic, so winning ways shift from 2,304 up to 21,609 on every spin. The gem theme is clear enough, and the layout is tidy. Stakes range from £1 to £100, which suits testing and serious sessions alike. I like the pace here, with steady drops powering cascades that can open the grid and create longer chains.
RTP sits at 95%, paired with high volatility and a max win of x5005. It's designed for swingy play, where drier spells can flip when features stack. The game uses HTML5, so it runs cleanly on mobile and desktop. I get the best out of it by leaning on the ways expansion, then riding cascades when the screen opens. The numbers are simple, but the synergy between features is what carries the sessions.

Free Spins Bonus in Extra Gems
Free spins land when three to six scatters hit. I've seen 9, 15, 21, or 27 spins awarded, matching the number of scatters. The round keeps the ExtraWays flow, so the grid can breathe and push the ways right up. This is where I've had my better runs, especially when the screen starts splitting and cascades find extra matches. The setup is straightforward, but it can stretch a single trigger into a proper stint.
During free spins, every scatter that drops adds 2 extra spins. That drip feed helps build momentum without changing the maths. I prefer a medium stake here, as the feature can take a while to arrive in a high volatility slot, then pay in clumps when it does. The best outcomes I've had combined retriggers with a growing multiplier, letting the ways, splits, and cascades pile on before the round runs out.
Symbol Split Bonus in Extra Gems
When a symbol on a vertical reel matches the symbol on the horizontal reel above it, the vertical symbol splits into two. In play, that simple rule can spike the number of winning paths, especially across the centre. I watch for early splits in a spin, as they tend to set up longer cascades. It's not a feature you click, it just happens, but it pulls real weight by opening the grid and feeding the ways count.
Win Multiplier in Extra Gems
After any win, symbols drop and a cascade checks for new matches. Each successful cascade lifts the win multiplier by one step, which stacks the totals when a spin keeps paying. When the chain ends without a new hit, the multiplier resets to x1. I've had spins start small, then ramp when two or three extra drops land. It rewards clustered hits rather than single lines, which fits the ways system well.
Extra Gems Symbols and Paytable
The paytable is tiered across gems. The top premium pays x25 for six of a kind, then x15 for five, x5 for four, x3 for three, and x1 for two. That early hit at two is handy on a ways setup, as it keeps more lines live. In my play, that symbol anchors the bigger totals, especially when splits create double landings across the central reels and cascades keep the spin active.
Mid-tier gems follow with six-of-a-kind pays around x4, x2.5, or x2, sliding down to x0.5 on three of a kind depending on the colour. I chart them as fillers that carry value once the multiplier starts stepping up. When ExtraWays expands the grid and a split fires, those mids tend to string together, pushing totals without needing a top symbol every time. They're the backbone of most of my base game hits.
Lowers round it out with six-of-a-kind pays near x1.5, x1, or x0.8, and three-of-a-kind entries around x0.2 to x0.1. The wild helps complete ways as usual, while the scatter is the ticket to free spins and retriggers. I keep an eye on how often those lows chain during cascades, as they drive the multiplier even when the raw pays are small. On a long drop, they matter more than the sticker values suggest.

Player Ratings & Comments on Extra Gems
From my sessions, Extra Gems is a proper high volatility grind with bursts of pace. The changing ways, symbol splits, and the cascade multiplier work together, so I set expectations around longer cycles and aim for that x5005 peak. I've had quieter patches, then a bonus with retriggers pushes totals sharply. Stakes from £1 to £100 give room to manage the swings. For me, it sits well in the rotation when I want ways play with stacking mechanics.
