Boulder Bucks

Boulder Bucks Slot Game

This interesting game from Barcrest combines a prehistoric theme with a couple of bonus features that set it apart from other games. Boulder Bucks features 5 reels and 10 fixed paylines along with some special symbols.

How to Play

The interface for this game is unusual: controls are along the left and right sides rather than along the bottom. To the left, you'll see the 'Stake/Line' window that allows you to adjust how much you want to bet per line. Use the + and - symbols to determine your wager. Whatever you bet will be multiplied by 10.

On the right side of the screen, you will find the 'Spin', 'BB', and 'Info' buttons. The green button at the bottom of the stack is the Spin button. Press it to start the reels in motion. The pink button above it is the Boulder Bucks button. At the bottom of the screen are windows displaying your balance and your wins.


There is no true Scatter symbol in this game. However, there is a Wild and several different Bonus symbols. The Wild appears only on reels 2-4 and can combine with other symbols to generate wins. It does not substitute for any of the Bonus symbols.

Free Spins Bonus

Landing three Boulder Bucks bonus symbols on reels 1, 3, and 5 triggers the Free Spins bonus. The symbol landing on the fifth reel determines which free spins game you'll get, from among the following choices:

Mammoth Spins – 20 free spins with expanding Wilds on reels 2-4
Pterodactyl Spins – 10 free spins with left-expanding Wilds on reels 2-4
Sabre-Toothed Tiger Spins – 6 free spins with expanding/sticky Wilds on reels 2-4

Egg Hunt Bonus

The Egg Hunt bonus is a picking game triggered by landing Dinosaur Egg bonus symbols during standard play. Choose from among a selection of eggs to win a multiplier or Free Spins.

Big Bet Bonus

This bonus offers you the opportunity to wager coins. Wager 20 coins and you'll get five spins. If the Boulder Bucks symbol appears on reels 1 and 3, you will have an opportunity to pick a dinosaur egg to see if you can get additional free spins. Wager 30 coins and you could get up to two Boulder Bucks symbols that work the same as the 20-coins wager.

To activate the big bet bonus, just click the pink button on the right side of your screen prior to any spin. The wager you decide on will apply to that spin, and that spin only.
