Buffalo Stack 'n' Sync Features

The SNS symbols represent the Stack 'n' Sync symbol and these stacks any paying symbol on the reels. A stack of 60 symbols fills the whole reel for massive wins. The first time that one or more of the Stack 'n' Sync symbols lands, they can fill a stack of 15, 30, 45 or 60 symbols. Only 1 Stack 'n' Sync symbol can land on each reel in each round.

Each of the Stack 'n' Sync symbols triggers a respin. If another Stack 'n' Sync symbol lands during respins, then those reels are synced together and spin.

When a full reel of buffalo symbols lands together, this activates a Stampede Reel with a multiplier of up to x100. If more than one Stampede Reels are part of the same winning payline, then these multipliers are added together.

There are two bonus games in this slot with the Free Spins feature triggered by landing 3 bonus symbols but the Stampede Spins triggered by landing 4 bonus symbols. Free Spins start with 10 free spins and high paying symbols are more likely to stack than in the base game.

The Stampede Spins start with 10 free spins and replace the normal reels with ones that only contain buffalo symbols and non-paying skull symbols. Each time the Stack symbol lands on the reels, 5 to 60 buffalo symbols are added to the reels and each stack awards an additional free spin.

Buffalo Stack 'n' Sync Review

The iGaming world absolutely loves buffalo slots as the market is completely oversaturated. This is why it came as a surprise as to why Hacksaw Gaming decided to release its own with Buffalo Stack 'n' Sync.

Playing on 5-reels with 10 paylines, this animal slot features a unique mechanic in the form of Stack 'n' Sync as well as multiple bonus rounds and stampede reels helping players win mighty wins of up to 10,000x the stake.


There is always a certain expectation when it comes to Hacksaw Gaming slots and sadly this one disappoints a little in terms of design. In the background of the slot, there is a decent static image of the Wild West but no life to it.

Similarly, the symbols on the reels do not look like anything overly special as they look just like any other animal slot with cliche images of eagles, buffalo, wolves and horses.

Thankfully, the slot is saved by the music and the Stampede Bonus game as this really brings the slot to life visually and audibly. The music is a guitar score that fits in with the American frontier and feels like something you'd find in a spaghetti western film.


Buffalo Stack 'n' Sync is bursting with charm and character in the form of gameplay. There is the Stack 'n' Sync feature as well as two bonus games to keep players entertained.

Like most Hacksaw Gaming slots, all the relevant buttons can be found at the bottom of the screen with the spin button and bet level button.

Win Potential

With Hacksaw Gaming, almost all the slots have a respectable win potential with a decent RTP and maximum win. Buffalo Stack 'n' Sync features a high RTP of 96.36% as well as a decent maximum win of 10,000x the stake.

This big win can be achieved through the bonus rounds such as the Stampede Reel with multipliers of up to x100. There is also a high volatility level leading to big wins but less often.

Our Verdict

Whilst this game does not look like anything too special on the surface, there is so much going on in terms of gameplay that players will struggle to be bored.

Buffalo Stack 'n' Sync shows developers how a good buffalo slot can be created. Fans of buffalo slots and Hacksaw Gaming should look no further than Buffalo Stack 'n' Sync.
