About Buffalo Stack’n’Sync

This 5×4 slot is built around stacked symbols, synchronised reels and two bonus modes, with a theme centred on the American Great Plains and premium animals like buffalo, eagles, wolves and cougars. Landing SNS symbols fills a reel with 15, 30, 45 or 60 matching symbols and awards a respin, while additional SNS symbols sync reels and copy the stacked layout across the grid. Stampede Reels create full stacks of buffalo with multipliers from 1× to 100× that add together when several connect to the same win. Both bonus rounds — Free Spins and Stampede Spins — award 10 spins and boost the odds of high-value stacked symbols. The max win reaches 10,000× your bet, with RTP values of 96.46% for Free Spins buys, 96.5% for Stampede Spins buys and 96.4% for FeatureSpins™.

Wild Symbol

Wild Symbol. The Wild symbol substitutes for all regular high- and low-paying symbols to help complete winning combinations. It does not replace bonus symbols or feature-triggering icons such as SNS symbols. Its purpose is to improve line wins and keep the base game more consistent.

Bonus Symbol

Bonus Symbol. The Bonus symbol appears only in the base game and is required to trigger the Free Spins feature. Landing three Bonus symbols awards 10 Free Spins with increased odds of stacked symbols during the round.

Stack’n’Sync™ Symbol (SNS)

Stack’n’Sync Symbol (SNS). The Stack’n’Sync symbol appears in both the base game and the Free Spins feature. When it lands, it fills a reel with a tall stack of identical symbols and awards a respin. Additional SNS symbols during respins synchronize the reels, copying the stacked layout across them for expanded win potential.

Stack Symbol (Stampede Spins Only)

Stack Symbol (Stampede Spins Only). The Stack symbol appears exclusively during the Stampede Spins feature. When it lands, it adds 5–60 buffalo symbols to its reel and awards an additional free spin. Multiple Stack symbols can expand several reels with buffalo, greatly increasing the potential for buffalo-line wins.

How to Play Buffalo Stack’n’Sync

Gameplay begins by selecting a bet size between €0.10 and €100. Wins pay along 10 fixed paylines from left to right. The core mechanic is Stack’n’Sync, a feature that fills reels with 15 to 60 matching symbols. When an SNS symbol lands, one respin is awarded and the stacked symbols remain locked. If more SNS symbols appear during a respin, all reels sync to match the stacked reel, copying its layout across the grid. Stampede Reels form when an entire reel fills with buffalo symbols, receiving multipliers ranging from 1× to 100×. If several Stampede Reels connect to the same winning payline, their multipliers add together before being applied. Free Spins are triggered by 3 bonus symbols and offer increased odds of stacked symbols during the feature. Landing 4 bonus symbols triggers Stampede Spins, a mode that focuses on buffalo, skulls and SNS symbols. Each SNS symbol that lands in this feature adds 5–60 buffalo to its reel and awards one extra spin. Bonus Buy options allow players to enter these modes directly, with RTP values shown inside the feature menu. Autoplay and turbo options are available, along with clear information on wins, balances and remaining spins. The maximum win is capped at 10,000×, after which the game immediately ends the round and awards the winnings.

Took a free spins bonus and Buffalo Stack’n’Sync went wild on me

I grabbed a no-deposit 100 FS offer and decided to try Buffalo Stack’n’Sync — and wow, this slot wakes up fast. The whole vibe is Great Plains with bright accents and stone-style symbols, and the animals feel like they’re ready to jump off the reels. The first thing that hooked me was the Stack’n’Sync feature. One SNS symbol dropped, filled an entire reel, and boom — respin. Then another SNS landed and suddenly the reels synced. That moment felt wild, like the whole game flipped into overdrive. My Free Spins round triggered from 3 flaming skulls, and my heart legit jumped. Inside the bonus, stacked symbols show up more often, and it really changes the pace. I had one spin where wolves covered a huge part of the screen but missed the full connection — painful. But in the final spins I landed a Stampede Reel with a 20× multiplier, buffalo lined up on a payline, and it paid around 60×. Not huge, but for free spins it felt amazing. The game is definitely spiky, but in that addictive “one more spin” kind of way. I’d absolutely play again, especially with bonuses — this slot shines when the reels sync and the buffalo start charging.
