Boulder Bucks Slot

Boulder Bucks Slots

Yabba Dabba Dooo! The first thing that came to my mind when I started playing this caveman-themed new online slot game from Barcrest was Flintstones vibes. While it’s not officially tied to the cartoon, it’s a clear nod to it.

As for the game itself, it follows the classic 5-reel setup with ten active pay-lines. It’s optimized as a mobile slot, performing well on all devices I tested, including a Windows phone. The game incorporates Barcrest’s variable RTP based on bet size and the ‘big bet’ feature seen in titles like Wild Knights Kings Ransom.

Surprisingly, this Barcrest title boasts modern 3D graphics and includes two free spins rounds along with a separate pick-and-win bonus feature. With prehistoric expanding and sticky wilds, you can play for free or switch to cash mode for a risk-free trial.

Theme and Features

While dinosaur-themed slots are common, caveman games are a rarity. Barcrest’s designers have excelled here, creating a vibrant and entertaining game with up-to-date visuals, music, effects, and characters.

The staggered RTP system is worth noting, offering a 94% RTP for bets under 2.00 credits, and a bump to 96% for higher bets. Playing the 20.00 credit big bet (5 consecutive spins) can unlock the Egg pick-me bonus with the boulder bucks symbol on reels 1 and 3. The game caters to high-stakes players and rewards them with more action.

The pick bonus lets you select one of three dinosaur eggs, each hiding a multiplier. However, the real highlight is the spins round, showing Barcrest’s commitment to enhancing bonus features in this latest title.

The spins bonus is divided into three sections, all triggered by landing three boulder bucks icons anywhere on the reels. The mammoth spins offer 20 spins with expanding wilds, while the Pterodactyl spins transform adjacent symbols into wilds. Lastly, the Sabre-Toothed tiger spins feature sticky wilds that expand to cover reels.

Summary

Barcrest’s games keep improving with each release, maintaining their signature staggered RTP and big bet features while adding more bonus entertainment and player engagement. This game caters to all player levels and is definitely worth a try as a real money slot with its abundance of wild features!
