I've spent a lot of time poking around Hacksaw Gaming's catalog. Buffalo Stack 'N' Sync marks the studio's first real dive into the North American wildlife genre, following Wanted Dead or a Wild.
This online slot brings a fresh perspective where a lone wolf or a soaring eagle can trigger big wins.
This buffalo stack’n’sync video slot goes for visuals that feel more cartoonish than Hacksaw's usual vibe. But don't let the art fool you—the mechanics pack a punch.
The action plays out on a 5-reel, 4-row grid with 10 paylines. Everything here is built around syncing reels with stacked symbols.
The max win sits at 10,000x the stake, and that mostly comes from the Stampede Reels multiplier system. If you're patient, these mechanics really reward you.
This buffalo stack'n'sync demo is absolutely worth testing before tossing in real cash, since volatility runs high and the swings can get wild.
Key Takeaways
-
This is a high volatility slot built around a respin mechanic that can snowball into full-reel wins.
-
The buffalo symbol carries the real prize potential, with a multiplier up to 100x boosting stampede wins.
-
A 10,000x max win and two distinct bonus rounds make this a title for players who accept longer losing stretches in exchange for bigger swings.
At-a-Glance Verdict And Core Specifications
Let’s dive in: with turbo mode on, the pace feels brisk. I noticed the s'n's symbol shows up often enough to keep things lively even when big hits are rare.
Landing the stack’n’sync symbol is how you trigger the respin sequence in the base game. It’s the heartbeat of the slot, honestly.

RTP Versions, Volatility, And Hit Frequency
Hacksaw Gaming usually ships slots with several RTP configurations, and this one sticks to that tradition. The base game RTP tops out at 96.36%, while the three bonus buy options have their own RTPs, ranging from 96.4% to 96.5%.
I’d definitely check which RTP version you’re playing, since a lower config can quietly chip away at your returns if you’re not careful.
Independent Reputation Context
No major community aggregator has published a specific community rating, trust score, or big-win tracker record for this title at the time of writing. That's pretty common for fresh Hacksaw releases before enough tracked spin data rolls in across the industry.
Great Plains Theme, Reels, And Paytable
The setting drops you into the Great Plains of North America, with a wild west vibe and roaming animal symbols filling the base game. If you’ve played buffalo slots before, you’ll recognize the setup—though here, the look is clean and simple instead of super cinematic.
Winning Combinations And Base Game Symbols
Wins pay left to right on the 10 paylines. Match up animal or low-paying symbols to score a payout.
Premium symbols like the horse, eagle, and cougar channel the rugged spirit of the American wilderness. You can almost feel the prairie wind in your hair.
High-paying Animal Symbols and Premium Symbols
The bison and buffalo symbols rule the paytable as premium icons. Horse, cougar, and wolf symbols also bring in solid returns.
The eagle and extra wolf symbols round out the high-paying lineup, with five of a kind paying up to 20x your stake. If you land a full line of premiums during a bonus, that’s where things can get spicy.
Wild, Scatter, And Special Symbols
A cactus wild symbol can show up on any reel and might carry a wild multiplier. These multipliers boost any win that includes the wild, which substitutes for any standard pay symbol.
The scatter is a flaming icon that unlocks the main bonus features. Land enough of them and you’re in the bonus game. Flaming scatters are your ticket to the big stuff, while skull symbols just hang out as placeholders.
Stack 'N' Sync And Stampede Reel Mechanics
This is where it gets interesting—the mechanic that gives the game its name. It’s actually pretty inventive compared to the usual stacked-reel stuff out there.
How Stack 'n' Sync Symbols Create Stacked Reels And Respins
When a stack 'n' sync symbol lands, it throws 15, 30, 45, or 60 extra symbols onto that reel. If the eagle gets picked, you can rack up big wins through this feature.
Each stack’n’sync symbol (or SNS symbol) triggers a respin, stacking the reels with more synced symbols as you go. It keeps you on your toes.
When Buffalo Stacks Become Stampede Reels
If you fill a reel with buffalo symbols, it merges into a giant symbol and triggers the Stampede Reels feature. Multiple stacked buffalo reels can connect and combine their multipliers, giving your win a serious boost.
Those stacked symbols are your ticket to the top prizes.
Multiplier Values And Big-Win Paths
Stampede Reel multipliers range from x1 up to x100, and you add them together instead of multiplying. Hitting the 10,000x ceiling from a full buffalo screen usually takes a combined multiplier around x50.
Free Spins, Stampede Spins, And Bonus Buy Options
Let's dive in! Two separate bonus games hide behind the scatter bonus symbol, and each one dials up the intensity in its own way.
If you're chasing that eye-popping 10,000x max win, entering a bonus round is the big goal. The free spins and stampede spins features both give you a shot at the game's wildest payouts, but they each take a different route.

Free Spins Feature With Enhanced Animal Stacks
Here's what surprised me: the free spins feature throws you 10 spins when you land those scatter symbols. Suddenly, premium animal stacks start showing up more often.
Don't be shocked if you catch a full screen of horses or eagles—it's a real rush. Wolves or cougars can take over the reels too, and that's usually when the big wins roll in.
These 10 spins also ramp up the chance of triggering Stampede Reels compared to the base game. It's a noticeable shift in momentum.
Stampede Spins And Skull Replacement Rules
This is where it gets interesting. Stampede Spins wipes away most symbols, leaving just buffalo, Stack, and skulls.
Now, the stack symbol becomes the star of the show. Land one and it'll add 5 to 60 buffalo symbols to a reel, replacing those dull skulls and tossing in extra spins for good measure.
Buy Bonus Options And Jurisdictional Limits
Thinking about buying a bonus? The menu with featurespins and other options isn't available to UK players, and sometimes it's restricted elsewhere too.
If you get the green light, activating featurespins lets you guarantee certain mechanics on every spin—a tempting way to shake things up. Always double-check if the buy option shows up before you get your hopes up at a particular casino.
Comparable Slots And Player Fit
Who May Enjoy This High-Variance Format
If you love watching a respin chain build and build toward a massive finish, this slot's for you. There's something thrilling about waiting for the eagle or bison to swoop in, and the shot at huge wins stays alive spin after spin.
Fans of Hacksaw's other wild west animal slot, Wanted Dead or a Wild, will feel right at home here.
When A Lower-Volatility Alternative May Fit Better
Not everyone wants that rollercoaster. If you're working with a small bankroll or just like steady, frequent wins, this one might test your patience a bit too much.
Honestly, a medium volatility slot might be a better fit for that kind of play style.

Strengths, Limitations, And Final Assessment
Pros And Cons
Pros
-
10,000x max win ceiling—way above the usual 2,500x–5,000x you see on standard video slots. That's a real head-turner.
-
The Stack 'N' Sync respin engine is honestly pretty wild. It can snowball into streaks of stacked reels you just don't see coming.
-
Two bonus rounds mean you can pick your poison: classic free spins or the higher-octane Stampede Spins.
-
The bonus buy menu gives you three price points, so you can target exactly the feature you want most.
Cons
-
High volatility—there's no published hit frequency, so you might hit a dry spell and not see it coming.
-
Multiple RTP versions exist, and not every casino will give you the top 96.36% number. Always check the fine print.
-
Base game wins outside the buffalo mechanic top out at about 150x stake, so if you're looking for frequent mini-jackpots, it's a bit limited there.
-
Bonus buy options are off-limits for UK players and possibly restricted in other places too.
Responsible Play And Next Steps
High volatility slots like this one need a bankroll built for wild swings, not quick wins. Set a loss limit before you play, and treat that 10,000x max win as a “maybe someday” dream, not a plan.
This buffalo-themed slot isn't for every budget or every mood, but it's just one of many high-volatility options out there. If you want to see how it stacks up, check out the site's full slot reviews collection and find your perfect match.
