Slot Summary

In 2016, Boulder Bucks turned a 5x3 Barcrest slot into a choice between three Free Spins packages rather than a single fixed bonus. The prehistoric cast separates the options: more spins with an Expanding wild, fewer spins with stronger wild behavior, or a short round where Sticky Wilds remain. Medium volatility and a 94.09% RTP leave the main distinction in that risk-and-duration choice.
MechanicsChoose spin volume against stronger Expanding Wilds

How It Plays

Base play runs across 5 reels and 10 paylines, with Wild Symbols substituting on the 3 middle reels. Scatter Symbols provide the route toward Free Spins.

When 2 Boulder Bucks symbols appear on the required outer reels, a Pick Me option can appear on the final reel. Revealing the third symbol activates the bonus choice.

Theme & Atmosphere

A Cartoon prehistoric cast carries Boulder Bucks through Forest and Jungle scenery, with a mammoth, pterodactyl, and saber-toothed tiger assigned to separate bonus modes.

The Nature setting is not detached decoration. Each Jurassic park creature signals a different Free Spins package, helping the player read the choice before selecting it.

Bonus & Free Spins

The mammoth option awards 20 Free Spins and places an Expanding Wild on the middle reels, favoring the longest round among the three choices.

The pterodactyl option supplies 10 Free Spins. Its Expanding Wild can convert symbols to its left into additional Wild Symbols during the selected round.

The saber-toothed tiger option gives 6 Free Spins, but its Expanding Wilds become Sticky Wilds and remain in place until the bonus concludes.

Bankroll survival simulator

How long could a bankroll last on Boulder Bucks? We simulate thousands of sessions from this game's published RTP and volatility — the long-run math, not a prediction of your next spin.

Volatility tier: Medium

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (Medium). The model is calibrated so the average return equals this slot's published RTP (94.09%), with wins capped at its top multiplier (1,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
