Review of the slot game Stampede Bonanza by Booming Games: a wild hunt for multipliers
Introduction
Stampede Bonanza is the latest slot from provider Booming Games, dedicated to the wild nature of North America. The game departs from classic payout lines in favor of the innovative model 'Scatter Pays', where wins are formed by the appearance of eight or more identical symbols in any position on the 6×5 grid.
Key Features
- The payout mechanics are 'anywhere' (Scatter Pays).
- Cascading wins (Cascading Reels).
- Random Wilds.
- Free spins mode with progressive multipliers.
- Feature Buy option.
Design and atmosphere
Stampede Bonanza immerses the player in a prehistoric atmosphere, populated by large predators. The graphics are rendered in rich, realistic tones: wolves, cougars, bears, and bison are depicted with stunning detail. The soundtrack enhances the dynamic: the roar of wildlife, the rumble of hooves, and the thunderous sounds of big wins. The overall impression is powerful, energetic, and contemporary.

Payouts for combinations (5 symbols on the screen)
Although the slot uses the 'Scatter Pays' model, for orientation, here are examples of payouts for five symbols, based on available information:
- Bison (the most expensive symbol): 100x the bet.
- Bear: 20x the bet.
- Cougar (cat): 10x the bet.
- Wolf: 5x the bet.
- Card symbols (A, K, Q, J, 10): from 1.5x to 3x the bet.
The actual payout depends on the total number of symbols on the screen (minimum 8).
Bonus functions and unique mechanics
- Cascading Reels: after each winning combination, symbols disappear, and new ones fall into their place, creating potential for a chain of wins within a single spin.
- Random Wilds: during cascades, random wild symbols may appear, replacing any base symbol to create new winning combinations.
- Free spins: activated when 4 or more Scatter symbols (depicted at sunset) land in any position on the field. For 4, 5, or 6 scatters, the player receives an immediate payout of 2x, 5x, or 20x the total bet respectively, as well as 10 free spins.
- Progressive multipliers in free spins: in this mode, a unique multiplier system is active. For every 22 winning symbols, accumulated in cascades, one multiplier (from 2x to 100x) is unlocked. A total of up to 10 multipliers can be unlocked, which are applied to the overall win at the end of the cascade chain.
- Bonus buy (Feature Buy): the player can immediately switch to the mode of free spins, paying 100x the current bet.
Expert opinions and recommendations
Stampede Bonanza is a slot for gamblers aiming for a big win. Its high volatility means that the base game can be expensive to win, but in free spins mode, the full potential is unlocked.
Strategy
Due to the low frequency of winning (28.9%), it is recommended to start with the minimum bet to stay in the game longer and wait for the bonus round. If your bankroll allows, the option to buy a bonus can be justified, as it is there that the most powerful multipliers are unlocked, capable of leading to a maximum win of 7500x.
Mathematical model
With an RTP of 95.30%, the slot is below the industry average (where the standard is 96%+). This is compensated by high volatility and enormous win potential. The low frequency of winning (28.9%) suggests that wins will be rare, but possibly very large.
Compared to analogs
- Sweet Bonanza (Pragmatic Play): higher RTP (96.48%), similar mechanics of Scatter Pays and cascades, but the theme and mechanics are less aggressive.
- Bonanza Megaways (Big Time Gaming): uses the Megaways mechanic instead of a fixed grid, but also offers high volatility and multipliers in free spins.
Mobile version

Stampede Bonanza is fully adapted for mobile devices. Thanks to the use of HTML5 technology, the game displays correctly and works without lags on smartphones and tablets under iOS and Android management.
