Crystal Skull (Endorphina): Slot Review and Free Play Demo

Crystal Skull (Endorphina) Review

Endorphina have a pretty nice track record when it comes to online slots, and we are always on the lookout for their new releases. In this review, we’ll take a look at Crystal Skull, which came out in November 2022 and which takes place across 5 reels, 3 rows and 25 paylines. It’s worth noting that the number of paylines isn’t fixed, so you don’t have to play with all 25 if you don’t want to.

Thematically, Crystal Skull will take you on an adventure, and you’ll get to visit some ancient temples yet again. It’s nothing original, really, but the slot’s presentation is polished enough, and there are even some neat animations to look forward to.

Let’s now take a look at the math model of Crystal Skull. There’s no official word about its volatility, but we estimate it to be medium-high. Similarly, we have no reliable info about the game’s jackpot, though we can tell you that you can enjoy the action for stakes between £0.01 and £75 per spin. The theoretical RTP of Crystal Skull is then always between 93.77% and 96.10%.

Crystal Skull Slot Features

The paytable of Crystal Skull features a set of 9 pay symbols, and it is possible to divide them into 5 low-paying symbols and 4 high-paying symbols. For low-paying symbols, there are your good old classic card ranks from Tens to Aces, and these pay up to 4x your bet per winning combo. For high-paying symbols, there are snakes, masks, statues and adventurers. Adventurer symbols are naturally worth the most, and they even pay out in sets of two. For a set of five, you’ll get a juicy 400x payout!

For special symbols, there are Crystal Skull Wilds, Pyramid Scatters and Bonus symbols. Crystal Skull Wilds can appear only on the three middle reels, but they work as Expanding Wilds, and they can even substitute for Pyramid Scatters.

Crystal Skull Slot – Bonus Wheel Feature

If you manage to land 3 Bonus symbols, you’ll trigger the Wheel of Fortune feature, which will net you a bonus wheel spin that can result in an instant coin win of up to 25x your bet. It can, however, also grant you a trigger of the Treasure Hunt Bonus feature, and that’s where the real fun begins. Note that you can respin the bonus wheel up to 3 times. Only the last spin counts, however, so be careful!

The Treasure Hunt Bonus feature itself is then all about picking items and progressing through up to 5 levels, with instant wins waiting for the luckiest of players. Just don’t reveal any snakes – those can even lead to a game over screen!

Players can then also try to boost their wins with the Gamble feature, which is all about trying to beat the dealer’s card. It’s nothing new under the sun, but at least you don’t have to guess any card colors or suits.

Finally, there’s the Bonus Pop option that allows you to purchase bonus features outright. You can pay 25x your bet to trigger the Wheel of Fortune feature, but you can also pay 109x your bet and get right to the Treasure Hunt Bonus feature!

Review Summary

To sum things up, Crystal Skull is a solid, if not particularly spectacular, online slot that will certainly find its fans. It’s got some nice bonus features, you see, though the absence of free spins is somewhat puzzling. In any case, it’s worth a shot if you’re into adventure-themed games!
