Buffalo Stack 'N' Sync introduces a brand-new and highly innovative Stack 'N' Sync (S'N'S) slot feature. What’s more, it also features two unique bonus games and even a FeatureSpins mode with very volatile action!

Betting Options and Bonus Features

This Hacksaw Gaming release is a wild west animal featuring symbols and artwork of barren countryside and local wildlife. You’ll be spinning a 5x4 reel set up with 10 paylines and a max win potential of 10,000x your stake.

The base gameplay is centered around 10 pay symbols that need to be connected in one of the 10 paylines to form a winning combo. Players need at least three matching symbols on the paylines to form a win and a wild symbol, illustrated by the Cactus icon, can make things run smoother as it can substitute for any regular symbol. In the event that you land 5 Wilds across a payline, they will pay out the same as the top-tier Bison symbol. 

The Stack 'n' Sync feature is triggered whenever you land an S'N'S symbol anywhere on the reels. It will inject 15, 30, 45, or 60 extra symbols of a randomly chosen type onto the reel where the symbol landed. You're guaranteed to get a fully stacked reel when 60 symbols are added to the reel strips. Furthermore, you receive one respin for each S'N'S symbol in view, and any additional S'N'S symbols on a respin will refill your tally. 

If a full stack consists of Buffalo symbols, it triggers the Stampede Reels feature. The whole reel will then be enhanced with a multiplier of up to 100x! This number will then boost any wins that are connected to the Stampede Reel. 

To trigger any of the bonus games, you’ll need flaming scatter symbols which can land anywhere on the reels. The Free Spins bonus round is high volatility and is triggered with 3 Scatters. You’ll obtain 10 free spins and your odds of landing Stack ’N’ Sync symbols are higher. You’ll moreover have a better chance of landing high-tier animal symbols including the iconic buffalo.

The Stampede Spins bonus round is the second bonus game of Buffalo Stack 'N' Sync and it triggers when you land 4 flaming scatters anywhere in view. You’ll again obtain 10 free spins and only be able to land non-paying skulls, the top-tier buffalo symbols as well as the newly unlocked special Stack scatter symbol. 

Each time a Stack symbol lands it will add 1 additional free spin and add 5 to 60 buffalo symbols on said reels. Keep in mind that the Stampeding Reel feature functions as usual so it's much easier to trigger.

Lastly, Hacksaw Gaming also added a bonus buy option. You can purchase both bonus games for 100x and 250x your stake, respectively. You can also activate the guaranteed Stack N Sync mode. It costs 15x your stake and it will guarantee a minimum 1 Stack N Sync symbol and a respin while it's active.

Roshtein’s Take

A super fresh take on slot gameplay that hasn’t really been done before. It definitely needs some polishing here and there but the gameplay is overall exciting. It’s obvious Hacksaw Gaming had streamers and the viewer experience in mind when they created this. 

The game is filled with big numbers and reactions even though the payouts don’t exactly match. Nevertheless, the game does deliver big wins but you might have to be a little more patient and might just have to reach a little deeper in that wallet of yours.
