The Gem Rocks mobile slot looks big and complicated, but it’s actually incredibly simple, with some monster wins smashing right through your screen.
This is not Yggdrassil’s first 4096 ways to win slot machine; that honour lies with the excellent Rainbow Ryan online game.
But, whilst we loved that first rendition, Gem Rocks improves on the concept by removing everything; no bonus features, no mini-games, nothing.
And we use the word ‘just’ lightly, considering that this is a deadly combination with the 4096 ways to win and 6 reels.
Basically, every time you get a win those symbols will disappear and give you more symbols cascading down from above.
You’ll also find 2×2 mega symbols on the reels, which to be honest, are mostly for show as with only 8 symbols, these often show up in clumps.
But it’s a nice show and one that is fun to watch, especially as all you need is a couple of little wins to see a real crushing avalanche of wins.
2 wins in a row will add one massive 2×2 symbol on the reels that guarantees a win as a monster rock smashes on to the screen.
You want those (not just for the obvious reasons) but because 5 wins in a row give you a 3×3 symbol and 9 wins in a row trigger a 4×4 mega symbol.
You can see wins of up to 9,000 times your bet here – that makes Gem Rocks easily one of the most volatile Yggdrasil phone slots.
Its simplicity is part of its rocky charm, but don’t think you are going to in finding 4×4 mega symbol every 100 spins.
In fact, we’ve gone whole play sessions and not seen a single one; they are rare beasts, much like hitting a jackpot.
But you know what we have gotten a few times? 2×2 and 3×3 mega monster symbols, and they are mighty fine to find; we’ve had wins of over 200 times our bet thanks to them.
Beginners should probably head to something a little easier on the wallet; the Incinerator slot, perhaps, which has an equally fun twist on the cascading wins.
Personally, we are sticking to this Gem Rocks video slot and chasing those monster wins whenever we can.

Avalanche Feature: Whenever you get a win, the symbols that create a win will disappear and more symbols will then tumble down from above.
The Gem Rock Feature: The one and only feature of the game, get 2, 5, or 9 wins in a row to get a Monster rock on the reels.
This Monster Rock will match one of the symbols already on show, and land somewhere that guarantees you a win. Depending on how many wins, this Monster will vary in size:
It might not sound like much, but it can be incredibly effective in giving this online mobile slot momentum and give you some real diamond size wins.
We were tempted to give this Gem Rocks slot review only 4 stars as this is far from a perfect game.
We know some people won't like that it doesn't have a lot of bonus game features, or that it's hard to get more than 6 consecutive wins at a time.
But we had such good fun playing it, and some great wins with such a simple concept, that we had to show our appreciation for a job well done by Yggdrasil.
If bonus features are your thing, then the 4096 ways to win Pink Elephants slot might be more for you.
But for us, the deadly combo of the monster wins, great graphics, and easy to understand mechanics makes this a must play.
