Crystal Vault

Produced by the well-established developer Lightning Box, Crystal Vault represents an exciting jump in quality and playing experience compared to many of their other more mediocre products. Indeed, this game delivers a comprehensively exciting and rewarding online slot from high-end graphic design to well-thought-out and engaging feature content. Mechanically this game has a pretty traditional format with five reels, three rows and 25 pay lines. The RTP is frustratingly just under the industry average sitting at 95.99%. That being said, the top payout here should have most gamers overlooking this previous stat as it comes in at an enormous 81,885x the stake. This game is available across mobile, tablet and desktop platforms.

Crystal Vault Overview

The features of this game begin with the dinosaur wild. This icon substitutes other symbols in the game to help players find more wins. However, this special symbol only falls onto the middle three reels. Next are the multiplier wilds, these icons operate the same way as the dinosaur wilds, but the displayed multiplier value boosts any win that uses them. However, these only appear in the bonus re-spin game, which is the main bonus feature. To trigger it, the player must land between three and five scatters on the board simultaneously. All features will be explained in more detail later in the review.

Crystal Vault Theme and Symbols

This game has an interesting fantasy theme that has the player explore a strange and magical new world using the red-headed adventurer as their avatar. From what we can piece together from some of the clues on the screen, this explorer has landed via seaplane on a mysterious and vibrant island full of amazing otherworldly flora and fauna in search of the Crystal Vault and its precious contents. Whether this intrepid adventurer succeeds in here mission is up to you and the luck of your spins. Although not entirely unique, this theme does show plenty of originality and is certainly exciting and enthralling.

The background is a depiction of this fantastic new place in which the explorer has found herself. To the left of the playing board is a temple covered in vegetation that looks like it could be a sacred place where this incredible Vault may be sequestered.

Right at the back right-hand corner of the screen is a steaming volcano, which from the looks of the recent lava flows, looks very active.
