Crystal Quest: Deep Jungle Review

Look and Feel

Crystal Quest: Deep Jungle in an online slot game from Thunderkick that was released in October 2020. Before we all accuse Thunderkick of jumping on the ‘themed slot’ bandwagon we must point out that this is the first slot from them that has the ‘Crystal Quest’ prefix, and we have no idea whether this series is likely to continue. The ‘Crystal Quest’ logo has been trademarked though, so in all likelihood it will become one. Thunderkick already has its own series though – the rather unfortunately titled ‘Beat the Beast’ series.

This series though is easy to get your head around. Crystal Quest will be – so we are told – the name of a continuing slotting adventure for an intrepid young explorer called Gemma. She will be visiting various environments in order to fulfil her need for crystals, and in Deep Jungle her destination is the Amazon rainforest. Gemma just loves them crystals … although we do not know why or what she does with them. We are sure that all will come clear in time, as will our opinion of this Thunderkick online slot if you keep on reading!


You can hunt for a progressive jackpot while you hunt for crystals during this game. You will find crystals but you won’t find a progressive jackpot as the game does not have one. You could win up to 15,000 times your stake though.

Play for Real Money

Even though this slot takes place in South America, if you play it in the UK it still falls under the jurisdiction of the UKGC. This means you won’t be able to play it in the UK for free or for play money. You can play it at plenty of places for real money though, including the Fruity Casa slots and casino site. Here you will find numerous offers and plenty of gaming fare to keep you entertained.


Your own quest with Crystal Quest: Deep Jungle begins when you select the size of your wager. The lowest accepted bet is £0.10 and the highest is £100. This is an ‘all ways pay’ slot with six reels, four rows and a mammoth 4,096 pay lines. A win is secured by landing consecutive identical symbols on the reels from the left-hand reel onwards. Win are paid as a multiple of your stake in line with the pay table below:

Symbol2 on a payline3 on a payline4 on a payline5 on a payline6 on a payline
Orange Gem-
Green Gem-0.40.711.6
Blue Gem-
Spade Gem-
Heart Gem-
Diamond Gem-
Club Gem-
Triangle Gem-
Hex Gem-

This slot is another cluster pays slot with the avalanche feature. All winning symbols vanish from the reels and new ones tumble in to replace them, potentially triggering new wins. There is the usual win multiplier too which increases by one every time an avalanche occurs. It resets whenever there’s a non-winning spin.

The game also has a mystery feature which will choose a symbol at random (not a wild or scatter symbol). If any mystery symbols land on the reels then they all change to the same, chosen symbol.

As is usual, the Wild symbol in this game substitutes for all other symbols apart from the scatter symbol. During the bonus game when a wild symbol lands on a non-winning spin it will explode and remove all symbols on the same reel and row.

To trigger the bonus game you need to land three treasure chest scatters anywhere on the reels. You will be awarded a dozen free spins. If you land an extra scatter to trigger the bonus game you will be awarded a further three spins.

You can add to your spins during the bonus game. Two scatters award three extra spins and one awards two. During the bonus game the multiplier does not reset on a non-winning spin.

Graphics and Sounds

We’ve become used to the high quality of Thunderkick’s graphics by now and Crystal Quest: Deep Jungle is absolutely no exception. The animation is spot on and there are some nice touches too – such as the way the winning symbols crack and the ape and lizard symbols react when they form a win. All looks good to us.

Sounds-wise, the game is played against the background of a gentle, Aztec-style jungle vibe. It only brings atmosphere though as you can barely hear it. The rest of the sounds are as you would expect – the tumbling and cracking of the reels and symbols. 


Gameplay wise, when it comes to new online slots in 2020, it has to be said … this game is so like another certain quest in the slotting universe it’s almost plagiarism. We’re not going to say which game – we did have it in our heads, but now it’s gone so you will have to work it out for yourself. If you’ve been playing online slots at any time since 2010 you’ll work out which one!

Despite this … similarity … Crystal Quest: Deep Jungle is still an excellent game and more than worth a spin or two. Why not go play it at one of our recommended casinos?
