Low value symbols come in the form of the high end of a deck of cards with 10 through to Ace. If the right amount of matching combinations land on a single spn then these symbols can offer between x1.5 and x15 the player’s stake. 

Next up, medium value symbols are represented by planes, purple fox-like creatures and colourful birds. These symbols can offer between x3 and x30 the player’s stake, depending on the amount of matching combinations that land in one go. 

Tigers and explorers depict the high value symbols, offering between x1 and x50 the player’s preferred bet. 

Dinosaur wilds can also appear on reels two, three and four, substituting for all symbols other than the bonus scatter. These wilds can appear in the bonus game with x2 and x3 multipliers to increase the win potential. 

Finally, bonus diamond scatters are available on all reels in the base game, triggering the free spins bonus game when three or more land on the reels at once. These scatters can also provide a payout between x0.2 and x4 the player’s bet. 


Landing three, four or five scatters will trigger eight free spins. In these respins, any two scatters that land on the reels at once will reset the number of free spins to eight and unlock the second reel screen. During the bonus rounds these scatters can only land on reels two and four of the first reel screen.

Unlocking the second reel screen will allow x2 wilds to appear on the reels. If another two scatters are collected on this board then the final reel screen will be unlocked with x3 multiplying wilds. 

All screens stay in play, meaning reaching the third screen allows players to spin on three reel-sets at once with x2 and x3 multiplying wilds appearing on every reel. 

These multiplying wilds can appear multiple times on the same spin, allowing a multiplier of x27 to become achievable. 


Michael Maokhamphiou, Operations Manager at Lightning Box, said: “The desert island theme present in Crystal Vault allowed us to experiment with mechanics and features that equally play into the overall narrative of the slot.

“This focus on scatters unlocking the vault and providing additional reels and multiplier wilds for players, allows the action to directly mirror the story within the title and is something we are sure players will adore.”
