Theme – Audio and Design Features – venture deep into the jungle

Crystal Queen Deep Jungle slot base game

As usual for a Thunderkick release, the design in the Crystal Quest: Deep Jungle slot is nicely done. It’s a little more understated than some of the developer’s other releases but the visuals do the job just fine.  With a jungle theme, you’ll head to a dense, green jungle. There’s little to grumble about with the design.

On the reels, symbols appear on stone blocks that could come from a jungle pyramid. There you’ll find an assortment of lower value gems and more rewarding crystal symbols.  The top standard symbol is the snake henchman which awards 1, 1.5, 2.5 or 5 x your total stake if you land 3, 4, 5 or 6 in combination. There are also wilds, scatters and mystery symbols which we’ll look at more closely in the bonus features section.

You can play Crystal Quest: Deep Jungle on a variety of devices including desktop, tablet and mobile. Thunderkick slots are usually very easy on the senses and this is no exception, even if you’re playing on a small screen. Combine that with the straightforward gameplay and you have a very playable mobile slot.

Bonus Features in Crystal Quest: Deep Jungle

There are plenty of opportunities for action in the Crystal Quest: Deep Jungle slot, starting with the avalanche reels which come with expanding multipliers. Look out too for expanding wilds, mystery symbols and of course, the free games feature.

Avalanche feature

Crystal Quest: Deep Jungle uses an Avalanche feature. After a winning combination lands, the successful symbols are blasted off the game grid and new symbols replace them. If a new winner is formed, the process is repeated.

Each successive winning avalanche also increases a multiplier by 1. This multiplier is then applied to the following avalanche. If you don’t create a new winner, the set of avalanches is over and the multiplier resets to its original 1x (in the base game).

Mystery feature

The treasure chest is the mystery symbol. All examples of this that appear on the same spin all transform into the same symbol which can be anything apart from the wild or scatter. A new payout calculation is then made with the newly transformed symbols in place.

Bonus Game feature

The monkey general is the scatter symbol. Land 3 monkey general scatters on the same spin and you’ll trigger the Bonus Game feature with 12 free spins. An extra 3 free spins are awarded for each extra scatter on the triggering spin. If you were to trigger with 6 scatters, you’d begin with 21 free spins.

Just like in the base game, the Avalanche feature is in play during the free spins. Each avalanche win increases the multiplier by 1. Unlike in the base game, the multiplier does not reset following a winless avalanche. It can only keep on rising throughout the feature.

The other main difference between the base game and the free spins is the Wild Explosion feature. This triggers if you land a wild during the free spins but it doesn’t result in a winning combination being created.

The wild symbol explodes vertically and horizontally, removing all the symbols in its path. New symbols then drop in. A new payout consideration follows with the new symbols active.

Finally, retriggers are possible too. Landing 2 scatters on the same spin adds 3 more free spins to your total. Any additional scatters on top of that add an extra 2 free spins.

Crystal Quest: Deep Jungle Review Summary – very playable all-rounder from Thunderkick

I liked this rainforest trek. The design is as high end as we’ve become accustomed to from the Thunderkick team. They’ve managed to pack in a very solid range of extras here too. The gameplay isn’t hugely innovative as there are similar features in other slots. The avalanche reels, expanding multipliers, mystery symbols and free spins mean there’s plenty going on here. Boring it ain’t.

The key to big wins is to increase the multiplier via successive avalanches. Your chances of winning big, up to 15,000 x stake per spin, increase in the free spins as the multiplier doesn’t reset. Put all that together and the Crystal Quest: Deep Jungle slot is a solid take on this ever-popular theme.

If you want avalanches and jungle fun, the Gonzo’s Quest Megaways slot by NetEnt ticks both boxes. In fact, it also offers free spins with the multiplier increasing by 3 with each avalanche (up to 15x). You can also win up to 21,00 x your stake per spin.
