If you’re in the mood for a digital detox now is your opportunity to rewind time and transport yourself back to the Stone Age when tools and weapons were hand crafted out of stone, creatures like dinosaurs and sabre-toothed tigers that are now extinct made their presence known, and there were no televisions or fancy gadgets that we now take for granted.
Crown Jewels is a 5 reels and 3 rows slot with 10 fixed paylines. The coin value starts with 0.01 $ and goes up to 40 $. So the top wager possible is 400 $ per spin.
In this prehistoric adventure you’ll be joining a local couple who are providing you with accommodation at their cave in exchange for assisting them in searching for elusive dinosaur eggs – and they’ve got a heap of cash hidden under boulders to reward you with!
Betting Big Bucks
Crown Gems Demon
The Boulder Bucks slot machine has been developed by Barcrest and consists of 5 reels and 10 paylines, with you able to jump in a time machine back to the stone age period from 10p up to £500 each time. While there is no technology to keep you up-to-date with the latest gossip, there is a free spins feature that offers three different modes and a pick ‘em feature where dinosaur eggs hatch to reveal big wins.
The return to player percentage varies based on bet size due to the Big Bet mode that we have also seen in other Barcrest slots like the Monopoly Big Event slot machine and the Barkin’ Mad slot machine being included. This sees a series of five spins play out one after another for a one-off fee of either £20 (which enables you to trigger the pick ‘em feature from the first and third reels only) or £30 (which sees only two Boulder Bucks symbols required across the first, third or fifth reels) – and you’ll even be cheered on by the chirpy caveman who pops onto the reels crossing his fingers in the hope of you triggering a feature or landing a huge win!

Back to the Stone Age
The Wild symbol in this Stone Age encounter has been carved out of stone and while it only appears on the second, third and fourth reels, it has the power to substitute for all but the bonus symbols (dinosaur eggs and Boulder Bucks logo). Our bearded caveman friend is the most valuable symbol of all so keep in his good books or he’ll smash you with his club, his wife takes care of the eggs you collect, their pet dinosaur appears very cute and friendly, plus there are Ace to 10 icons designed in the style of boulders.

Free Spins Hide Under the Rocks
Free spins are hidden under boulders in this slot with the Boulder Bucks logo being key to spinning the reels for free. You’ll need one to land on the first, third and fifth spin at the same time with the symbol that lands on the fifth reel containing a number between one and three to determine the number of choices you get to make. Why’s this? Well, there are three different free spins modes and if you’re lucky enough you could get to experience them all one after another!
Mammoth Spins: Distinct for their long-curved tusks, the beastly mammoth sees you receive 20 free spins with Expanding Wild symbols appearing on the second, third and fourth reels.
Pterodactyl Spins: Enjoy high-flying wins whenever you choose Pterodactyl free spins as you receive 10 free spins with Side Expanding Wilds that turn all symbols to the left of them into additional Wilds.
Sabre-Toothed Tiger Spins: My favourite of the three modes has to be the Sabre-Toothed Tiger, and not just because I’m scared of its razor-sharp teeth. This ferocious creature sees you receive 6 free spins with Sticky Wilds that expand and remain in place until the rest of your spins have been played.
If you’re not overly impressed with your winnings from the free spins feature that you selected and you received more than one choice when triggering the feature, you could actually choose to reject your winnings before selecting one of the other modes instead, in the hope that they bring the colossal wins that you’ve longed for!
