Boulder Bucks Online Slot Review

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% 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, a rare choice of three free spins modes, and Barcrest’s signature Big Bet side-bet. Explore it at our favorite Barcrest slots sites.

How to Play Boulder Bucks

• Grid & lines: 5 reels, 10 paylines (left-to-right wins).
• Stakes: Choose a bet from 0.10 to 500 credits per spin via the bet control, then hit Spin.
• Mobile: Fully compatible with iOS/Android; clean on-screen controls for stake and spins.
• Pays & symbols: 3+ consecutive matches on a payline trigger line wins. Wilds substitute; scatters/bonus icons unlock features.

Note the paytable shifts with stake: under two credits per spin, you’ll see one prize ladder (e.g., up to 500× line bet); over two 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 five linked “super” spins with elevated feature odds and higher RTP:

• 20-credit Big Bet: Bonus symbol assistance on Reels 1 & 3.
• 30-credit Big Bet: Assistance on Reels 1, 3 & 5 (easier feature entry).

The overall RTP can climb as high as 98% with optimal play. (Feature availability can vary by region—always verify in your casino’s game info.)

Our Boulder Bucks Verdict

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 flavor? 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 your stake's paytable and feature notes to understand how assistance and RTP change—minor strategic tweaks can materially boost long-run value.
