Boulder Bucks from Barcrest is a prehistoric-themed, five-reel slot with 10 paylines and far more control than meets the eye.
With a variable RTP that can swing from 77.91% up to a headline 98% (with the right Big Bet strategy), medium variance, and a max payout of 250,000 credits, it’s a compelling choice for players who like to fine-tune risk and reward.
You’ll find wilds, scatters, pick bonuses, and a rare choice of three free spins modes, plus Barcrest’s signature Big Bet side-bet. Explore it at our favourite Barcrest slots sites.
Note the paytable shifts with stake: under 2 credits per spin you’ll see one prize ladder (e.g., up to 500× line bet); over 2 credits per spin or with Big Bet, the pays restructure (e.g., 5–250× line bet) and feature odds/RTP improve. Check the in-game Help/Paytable for exact values at your chosen stake.
Barcrest’s Big Bet buys you 5 linked “super” spins with elevated feature odds and higher RTP:
With optimal play, the overall RTP can climb as high as 98%. (Feature availability can vary by region—always verify in your casino’s game info.)
Boulder Bucks stands out by letting you shape the experience: standard spins or Big Bet, three distinct free-spins styles, and the accept/retry wrinkle if you’ve banked multiple picks. If you enjoy classic Barcrest pacing with modern control levers—and serious top-end RTP potential—this one’s a smart pick among the best online slots.
Ready to dig for wins? Spin it for real at top online slot sites, or try the demo first. Prefer a different Big Bet flavour? Check Hercules High & Mighty (up to 10 rows/100 lines) or Soldier of Rome for a meatier medium/high-variance ride.
Pro tip: If you use Big Bet, consult the paytable and feature notes at your stake to understand how assistance and RTP change—small strategic tweaks can materially boost long-run value.
