RTG has launched Buffalo Mania: Thunder Springs on Online Casino Games. This latest release gives fans a new high-energy Buffalo slot. The title also strengthens RTG’s presence in both US crypto casinos and every major US online casino platform.
Players now have access to a dynamic game that blends expanding reels, strong multipliers, and modern hold-and-spin mechanics. As a result, the title enters the market with strong momentum. It also reflects RTG’s continued push for feature-rich premium slots.
Buffalo Mania: Thunder Springs Main Features

Buffalo Mania: Thunder Springs uses a 5×4 layout with 1,024 ways to win. The ways can grow during special features. Therefore, players may experience sudden spikes in win potential during expanded spins.
The game supports cascading combinations, which allow new symbols to drop after each win. This mechanic increases excitement and extends win sequences.
Buffalo Mania: Thunder Spring runs on high volatility, creating bigger but less frequent hits. Because of this, the experience suits players who enjoy high-risk gameplay. In terms of theme, the game centers on wild American landscapes with strong visual effects and smooth animations.
Additionally, the maximum payout reaches impressive levels when features combine with multipliers. This gives the game a competitive position among Buffalo-themed releases across US crypto casinos.
Special Features
Geyser Eruption Expansion

A Scatter Geyser symbol on reels 2, 3, or 4 triggers the Geyser Eruption Expansion. All wins are paid on the standard 5×4 grid first. Then the reel with the Scatter expands upward by three rows, while adjacent reels expand by two rows each.
Players receive three Free Respins using the expanded layout. After the Respins finish, the gameboard returns to its normal size.
However, only one geyser can activate per spin, and this feature appears only in the Base Game.
Free Games

Landing 3 or more Scatters awards 8 Free Games. During Free Games, if one or more Scatter Buffalo symbols appear, each will trigger a Bonus Reveal animation that results in one of two possible outcomes:
- Awards 3 additional Free Games
- Expand the gameboard by adding one new row (up to a maximum of 3 additional rows)
Moreover, every Scatter Buffalo symbol that appears during Free Games will trigger its own independent Bonus Reveal. Once the maximum expansion level is reached (+3 rows total), any subsequent Scatter Buffalo symbol will only award additional Free Games.
Additionally, the expanded wheelbox remains active for the remainder of the Free Games session. Lastly, Free Games end when no more Free Games remain or when the maximum payout is achieved.
Hold & Spin with Wild Stampede

Three or more Coin symbols trigger Hold & Spin. The feature begins with a 5×4 wheelbox and three locked rows above it. Triggering Coins lock in place and award three respins.
New Coins lock and reset respins to three. Coin values represent bet multipliers. Rows unlock at 8, 16, and 20 Coins. If all positions are filled, the Grand Jackpot of 1,000× bet is awarded.
Verdict

Buffalo Mania: Thunder Springs delivers strong mechanics, high volatility, and modern bonus play. Its mix of expanding reels and high multipliers makes it ideal for both US crypto casino and US online casino aficionados.
If you haven’t experienced running with the wild buffalo, you need to play this game. Buffalo Mania: Thunder Springs provides amazing spins, and huge potential wins.
