Boulder Bucks by Barcrest is a 5-reel, 10-payline slot with a 94.09% RTP and stakes from 0.1 to 500. The game uses a cartoon prehistoric setting with cavemen, mammoths and dinosaur-style symbols, alongside rock-letter icons such as A, K, Q, J and 10.
The paytable shows standard line wins across 3, 4 and 5 matching symbols, with Wild symbols used as substitutes on reels 2, 3 and 4. Free spins are built around two feature variants: Mammoth Spins, offering 20 free spins with expanding wilds, and Pterodactyl Spins, offering 10 free spins with side-expanding wilds that turn symbols to the left into additional wilds.
This demo version lets players play for free and practice before playing for real money. The review format near the launcher highlights the main mechanics, bonus games and symbol rules in a brief, factual summary.
