Crystal Vault Features

Despite having such a huge maximum win, this slot keeps it simple with two main features. Firstly, there are wilds that land on the reels and can substitute all other symbols except scatters and multiplier wilds. Multiplier wilds land on reels 2 to 4 and only appear during the Bonus Respin when reel 2 is unlocked.

The biggest draw to this slot (aside from the huge payout), is the bonus respin round. 3, 4 or 5 scatters trigger the bonus round to gain 8 spins. Any 2 scatter during this feature, resets respins to 8 and unlocks additional reel screens with a maximum of 3 available.

Wild multipliers of x2 unlock on reel screen 2 after the first trigger and remain unlocked for the remainder of the bonus round. A wild multiplier of x3 is unlocked on reel screen 3 upon the second retrigger. Multipliers can reach up to x27 throughout this bonus round.

Crystal Vault Review

The spirit of adventure is alive and kicking with Lightning Box's Crystal Vault. Journey deep into the jungle to find the hidden vault securing fortunes of up to 81,885x the stake.

Published by Light & Wonder, Crystal Vault is an adventure slot that plays on 5-reels with 25 paylines - but has the potential to lead to 3 different sets of reels and bonus rounds leading to epic wins.


As the slot opens up, it's surprisingly quite tasteful for Lightning Box with a colourful and vibrant background that feels quite modern. The visuals are actually stunning in places with the creatures looking marvellous and exotic.

When the slot begins, you'll find yourself at the forefront of a temple surrounded by mountains and a volcano in the distance. It seems that the star of this slot is the female explorer on the reels who acts as one of the highest paying symbols.

Sadly, we were hoping for more of a focus on her but she soon fades into the back with the rest of the symbols. Even during the free spins round, she is sidelined for the wonderful interior visuals of the mysterious Crystal Vault.

The minute the free spins round begins, players will be treated to a marvellous cave surrounded by treasure, running lava and crystals. It's a sight to behold that will certainly leave players gasping.

In terms of the audio, there are ambient sounds throughout such as birds and rustles. However, the best part of the audio is easily the music building up with steel drums, percussion and bells to create something befitting.


When Crystal Vault loads up, do not be put off by the lack of features. There are only two main features with the bonus round and the multiplier wilds - but these both lead to satisfying moments throughout.

However, if you are looking for a feature-heavy slot, then we suggest checking out any of the Nolimit City slots. If you are looking for a simple but entertaining slot, then Crystal Vault will have you covered.

Win Potential

This slot is definitely strange in terms of the win potential. Firstly, the RTP is under the average standard but only just at 95.99% which means it's easy to overlook. In addition to this, there is a massive maximum win of 81,885x the stake which will please players.

However, this slot is a low volatility game meaning that there are smaller, frequent wins rather than big ones. Whilst the maximum amount is huge, it means that the chances of securing this are highly unlikely and a player may never achieve a big win like this. Despite this, there is still a chance players can win this and it gives low volatility players the chance to win something grand.

Our Verdict

There aren't many slots that can boast of a crazy win of up to 81,885x the stake - but Crystal Vault sure can. The odds of getting this maximum amount are slim considering the volatility and the RTP, but this does not mean it isn't still appealing.

Crystal Vault is simple to its core with only one bonus round and the main feature to keep players engaged. This is certainly for a special type of player wanting minimalistic gameplay with frequent wins and the chance of winning big. If you fit this niche, then Crystal Vault is the slot for you.
