Crystal Quest: Deep Jungle (Thunderkick) – It’s a charming, captivating and easy-to-play slot

Thunderkick loves to stand out. Often, they introduce some bizarre animals, such as in Pink Elephants 2. It’s no different here.

The main characters are not the usual adventurers (like Gonzo in Gonzo’s Quest or Rich Wilde in the many Play’n GO slots) but two remarkable beasts.

The most prevalent one is a Monkey who is a General at the same time (“Monkey General”), and the other one is a Snake who is also a Henchman (“Snake Henchman”). Henchman stands for an unimportant person. I guess we know who the boss is in this jungle!

Crystal Quest: Deep Jungle offers a top win of an astonishing 15,000x the stake

And that’s massive for a Thunderkick slot. Only Riders of the Storm and Carnival Queen have higher maximum wins.

Software: Thunderkick

Number of paylines: 6×4 setup and 4,096 ways to win

RTP and variance: 96.14%, Medium to High variance

Maximum win: 15,000x the bet

Betting range: $€0.10 – $€100

Bonus features: Free Spins (Bonus Game)

Casino Hipster verdict: It’s an enjoyable and hilarious themed slot. The gameplay lacks a bit of originality.

Crystal Quest: Deep Jungle slot – Gameplay and Features

The game has 6 reels with 4 rows of symbols. There are 4,096 ways to win.

I already introduced the two highest paying symbols: the Monkey General and Snake Henchman. The three medium symbols are the three crystals, and the six lower paying symbols are all gems.

Furthermore, you have a Wild symbol (a “W”) that replaces all symbols except the scatter, the purple-gold treasure chest. You also have Mystery symbols.

Avalanche feature

The gameplay has built-in the Avalanche (Cascading or Tumbling) mechanism.

After a winning combo, you get a free respin, and the winning symbols disappear, and new symbols replace these. The respins continue as long as you keep on making winning combos.

There is also a multiplier that increases by +1 with each respin. The multiplier only resets once you fail to make a new winning combo.

How to get the free spins?

3 Scatters gets you 12 free spins. For each scatter you spin during the free spins, you get another 3 free spins, and there are no limits.

The free spins: the Wild Explosion Feature and increasing multipliers

The gameplay of the bonus game (the free spins) is the same as that of the main game, but there are two essential differences.

The Wild Explosion Feature: if you don’t get a winning combo, but do get a Wild, the Wild symbol explodes. All symbols on the same reel and row disappear and are replaced by new symbols. Therefore, you get a second chance to make winning combinations.

Increasing Multipliers: the multiplier continues to rise after each winning combo and does not reset if you fail to make one.

The recipe is to spin as many winning combos as possible at the beginning, to get a multiplier as high as possible. If you land a lucrative combo afterwards, it can go sky-high. Don’t forget that you have 4,096 ways to win!

Payout percentage (RTP)

The payout percentage is 96.14%, and that’s fine, although it’s not resoundingly high.

Crystal Quest: Deep Jungle slot – the variance (volatility) is medium to high

The volatility has a value of 8.41, according to Thunderkick. Freely translated, this means that the variance is medium to high despite the relatively high max win.

I expect that chances of landing the max win of 15.000x must be marginal and that most top wins will be around 500x to 1000x the bet.

Pros en Cons


  • Delightful and eccentric theme.
  • The slot is easy to get into.


  • Not the most complicated slot.
  • The gameplay is not very original, but it doesn’t always have to be.

So, who’ll like the slot? And who won’t?

This Thunderkick slot suits players who don’t want to play an overly complicated slot, but seek entertainment and laughter. And the fact that some wins can be a massive helps!
