Head out onto the Great Plains with Buffalo Stack’n’Sync, an animal-themed slot from Hacksaw Gaming that combines classic Western scenery with a distinctive reel-stacking mechanic. Featuring mighty buffalo, soaring eagles and other wildlife, this game puts a fresh spin on the familiar buffalo slot formula with synchronized respins, full-reel symbol stacks and multipliers that can reach 100x.
The main attraction is the Stack’n’Sync feature, which can transform entire reels into matching symbols before synchronizing their positions during respins. Add Free Spins, the powerful Stampede Spins bonus and an advertised maximum win of up to 10,000x your stake, and there's plenty to explore.
Here's how Buffalo Stack’n’Sync works and what to know before playing at Jacks Club.
How to Play Buffalo Stack’n’Sync
Buffalo Stack’n’Sync uses a 5-reel, 4-row layout with 10 fixed paylines. Winning combinations are formed by landing matching symbols on adjacent reels, starting from the leftmost reel along a valid payline.
The symbols draw inspiration from the North American wilderness. Card ranks provide the lower-value combinations, while animals such as wolves, eagles and buffalo offer higher-paying possibilities. The cactus acts as the Wild symbol, substituting for regular symbols to help complete winning combinations.
The game's defining feature is its ability to fill reels with stacks of matching symbols. Rather than relying solely on individual symbol positions, Stack’n’Sync can turn a reel into a wall of identical icons, potentially creating several winning combinations at once.

The Stack’n’Sync Feature
Stack’n’Sync is the central mechanic in the base game. When one or more Stack’n’Sync symbols land, the reels where they appear are filled with a stack of one paying symbol. The stack can contain 15, 30, 45 or 60 symbols, with a 60-symbol stack filling an entire reel.
Each Stack’n’Sync symbol awards a respin. If another Stack’n’Sync symbol lands during these respins, its reel synchronizes with a previously stacked reel, copying its symbols and stopping in the same position.
This creates opportunities for matching stacks to line up across multiple reels. When the same paying symbol fills several synchronized reels, the result can be a large number of winning combinations.
Only one Stack’n’Sync symbol can land on each reel during a round, so the feature revolves around building and synchronizing the available stacks. The result depends on which symbols are selected and how the reels align; a full stack does not automatically guarantee a significant payout.
Stampede Reels and Buffalo Multipliers
Buffalo symbols have a special role in the game. When an entire reel lands filled with buffalo symbols, it becomes a Stampede Reel and receives a multiplier.
These multipliers range from 1x to 100x. The multiplier applies to winning paylines featuring buffalo symbols that connect to the Stampede Reel. If multiple Stampede Reels contribute to the same winning payline, their multiplier values are added together before being applied to the win.
For example, if a qualifying payline connects to two Stampede Reels carrying 10x and 15x multipliers, those values combine to produce a 25x multiplier for that win.
This mechanic gives full buffalo reels a particularly important role. A stacked reel is useful in its own right, but a buffalo stack that activates a Stampede Reel can add a multiplier to qualifying payouts as well.
Free Spins Bonus
Landing three Bonus symbols in the base game triggers the Free Spins feature. This bonus begins with 10 free spins and gives you additional opportunities to use the Stack’n’Sync mechanic.
The feature is designed to make stacked symbols more prominent, giving you further chances to fill reels and create synchronized combinations. If additional Stack’n’Sync symbols land during the bonus, they can award respins and help build larger stacks.
The Free Spins round offers a different way to experience the game's main mechanic, with the potential for multiple stacked reels to align across the grid. As always, the number of wins and their value depend on the symbols that appear.
Stampede Spins: The Bigger Bonus
Landing four Bonus symbols in the base game triggers Stampede Spins, a separate bonus feature built around buffalo symbols and stacks.
The feature begins with 10 free spins. During the round, the reels contain buffalo symbols, Stack symbols and non-paying skull symbols. When a Stack symbol lands, it adds a stack of between 5 and 60 buffalo symbols to the relevant reel, replacing skull symbols.
Each Stack symbol also awards an additional free spin. This gives the feature the potential to continue while buffalo symbols fill more of the grid.
The objective is to build large buffalo stacks across the reels, creating opportunities for winning paylines and powerful Stampede multipliers. The feature's combination of extra spins, stacked buffalo and multipliers makes it the game's main high-potential bonus.
RTP, Volatility and Maximum Win
Buffalo Stack’n’Sync is a high-volatility slot. Wins can be unevenly distributed, with quieter stretches between larger payouts. Players should be prepared for fluctuating results rather than expecting frequent substantial wins.
The commonly advertised RTP is 96.36%, but alternative configurations are available, including lower settings. RTP represents a theoretical long-term return across a very large number of spins, not a prediction of what an individual player will win. Check the game's information panel at Jacks Club to confirm the RTP for the version available.
The maximum advertised win is up to 10,000x your stake. This is a theoretical upper limit, not a typical result or a guarantee of winnings.
