Crystal Skull Dice Slot Overview
Endorphina took its Aztec temple slot Crystal Skull and turned every symbol into a golden die. That is the whole idea, and it holds up better than a gimmick like this usually does: coloured gem pips take over the job the card ranks used to do, while the masks and idols sit on the faces of the cubes like loot pulled out of a tomb.
The bonus is what makes it worth a look. There are no free spins anywhere in this game. Three Bonus symbols open a multiplier wheel, and that wheel either pays you a slice of your total bet or hands you a ticket into a five-level pick game guarded by snakes. Everything above a modest line win comes from those two rounds, including the 3,000x ceiling.
Theme & Design
The reels sit on a slab of white marble inside a gold Aztec frame, fretwork edges and small green gems set into the corners. Two huge blue-grey stone warrior heads face each other on either side of the grid with braziers burning at their bases, torchlight washing warm orange up the columns while a starry night sky shows above the temple roof. The contrast between that cold pale marble and the fire around it is a bit odd, and the marble panel does read as a plain backdrop rather than temple floor.
The dice themselves are the best part of the art. Chunky gold cubes, glossy, with faceted gemstone pips: rubies on the two, sapphires on the three, amber and citrine on the fours, amethyst on the fives and sixes. Picture cubes break up the run of them, a feathered jade mask, a gold idol face, a twin-headed serpent in green relief, a sun-stone medallion, and a stepped pyramid on a red tile. Top of the pile is a woman explorer in a wide-brimmed hat lit by a gold halo, which is a nicer touch than the generic bearded adventurer these games usually reach for. The Crystal Skull Wild lands as a clear crystal skull glowing green through the whole reel when it expands.

Features & How They Work
Expanding Crystal Skull Wilds
The Wild only lands on reels 2, 3 and 4, and it does not just sit there. When a Wild can complete a paying line, more Wilds appear on that same reel until it fills, which is where the good base-game hits come from. There is one restriction that matters: when a Wild is completing a combination with the Pyramid Scatter it stands in for one Scatter on that reel and will not expand there.
Wheel of Fortune
Three Bonus symbols start the wheel. It spins, stops at random, and lands on either a multiplier of your total bet (x10, x12, x15, x20 or x25) or on a BONUS wedge that opens the Treasure Hunt. You then choose: take what the wheel gave you, or respin for something better. Up to three attempts, and only the last one counts, so respinning a x25 down to a x10 is entirely possible. That decision is the sharpest moment in the game.
Treasure Hunt Bonus
Landing the BONUS wedge and pressing TAKE WIN drops you into a five-level pick game, five carved stone masks per level. On the first three levels the masks hide gemstones, and every one you find pays a slice of your total bet and pushes you up a level. Levels four and five swap in artifacts and snakes, the treasury keepers, and this is where it gets interesting: a snake sometimes turns into an artifact and lets you through, sometimes it strikes and the level is over. All prizes are added up and paid at the end. There is no way back to the wheel once you are in here.
Bonus POP
A round Bonus POP button sits at the lower left, and it buys direct entry to the Treasure Hunt. Price scales with your stake and works out around 109 times the total bet, so a 0.25 spin costs 27.25 to skip the wait. The bought round opens with a base spin that lands the Bonus symbols for you, then goes straight into the pick game. Some operators switch this off, and anything won through it cannot be gambled.
Risk Game
Endorphina puts its usual card gamble on top of any win. Beat the dealer, double up, keep going or bank it. It is the same gamble ladder from the rest of their catalogue and nothing here changes it.

How Crystal Skull Dice Plays
Base spins are quick and thin. Gem dice hits arrive at a steady enough rate to keep the balance ticking, but they are 0.05 and 0.20 sort of wins on a 0.25 bet, and with the Wild boxed into the middle three reels the expansions usually just widen a four-symbol line instead of building something worth watching. Nothing accumulates between spins. No counter, no ladder, no meter creeping toward anything.
So the whole session hangs on the Bonus dice showing up, and then the game becomes a completely different thing for two minutes. The wheel makes you decide something. Treasure Hunt is slow and deliberate in a way modern slots rarely bother with, five choices that each carry weight, and it can end on the second one. Most players will burn all three wheel attempts chasing the BONUS wedge, and honestly that is the right instinct.
The distance between those two states is the problem. Between bonuses this plays like a line slot from a decade ago wearing better clothes, and the wait can feel long enough that the buy button starts looking reasonable.
Pros & Cons
Pros
- Two-stage bonus with an actual decision in it, not just a wheel that pays and closes
- Treasure Hunt runs five levels deep instead of the usual one-pick-and-done
- The dice conceit is worked through properly, with pip colour doing real work as a pay hierarchy
- Direct buy into the top feature if you would rather not grind for it
Cons
- Nothing happens between bonus rounds beyond small line wins
- RTP is operator-configurable and can be set as low as 93.77%, so the same game pays differently depending on the casino
- Wilds never touch reels 1 and 5, which limits what the base game can put together
- Bonus symbols are stubborn, and dry stretches run long
Is Crystal Skull Dice Worth Playing?
The dice re-skin could have been a lazy palette swap and it is not. Pip colour carries the low-pay hierarchy cleanly, the picture cubes still read as temple treasure, and the warrior heads flanking the reels give it more atmosphere than the base version had. Underneath the art, though, this is a 25-line game built on an older template, with a two-stage bonus carrying almost all of the interest.
Endorphina priced the shortcut at roughly 109x the bet, which tells you plainly where the value sits. Spin it straight and you will spend a lot of time on small gem-dice hits waiting for three Bonus symbols to line up. The Treasure Hunt is good enough to justify that wait, right up until the snakes start appearing on level four.
