Buffalo Stack ‘n’ Sync Slot Review

Buffalo Stack’n’Sync Slot Review

I have spun plenty of Hacksaw titles, and Buffalo Stack’n’Sync feels like their straight take on the North American prairie theme. The backdrop is all cacti, red rock and an empty sky, with the soundtrack giving it a slightly eerie edge rather than a full on gunslinger vibe. Under the hood you get 5 reels, 4 rows and 10 paylines, with high volatility and a top win of 10,000x your stake.

RTP comes in several settings, so I always check the info panel before committing a balance. The best version sits at 96.36 percent in standard play, nudging higher through the feature buys. Volatility is rated 4 out of 5, and the game can feel very streaky, especially if Stack’n’Sync symbols stay away for a run of spins.

Base Game and Features in Buffalo Stack’n’Sync

Buffalo Stack’n’Sync is a simple 5x4 layout with 10 fixed paylines that pay from left to right. You need three to five matching symbols starting on reel one. Stakes run from 10p up to £100 per spin, so it covers low and high rollers. The pace is excellent with the turbo switched on, and the base game is basically about waiting for Stack’n’Sync or full buffalo reels to land.

Low pays are the standard 10, J, Q, K and A. Five of a kind pays between 2x and 4x your bet. Premium symbols are a horse, cougar, wolf, eagle and the top tier buffalo. Land five premiums and you are looking at 10x to 20x your stake, with the buffalo leading the pack. Values sound modest at first, but they come alive once stacks and multipliers start lining up.

The cactus is the wild symbol and appears on any reel. It substitutes for all regular symbols and pays the same as the buffalo if you land five on a line. Between the stacked high paying animal symbols, wilds and only 10 lines, the game can throw in nice line hits even before the main features turn up, though dry spells are very common on a cold session.

Stack’n’Sync Feature in Buffalo Stack’n’Sync

The Stack’n’Sync symbol, marked SNS, is the engine that drives most of the excitement here. When one lands, its reel is loaded with a stack of 15, 30, 45 or 60 copies of a single symbol. You also receive one respin for each SNS in view. On the respin, any extra SNS symbols sync with the already stacked reels and copy their chosen symbol.

If 60 symbols are added to the strips, that reel becomes fully stacked, which is where screens full of the same animal or card rank can appear. The dream is having buffalo chosen as the stacked symbol, then linking them with multipliers from Stampede Reels. In practice, you will often see SNS symbols building stacks of mid range animals or royals, but the feature still adds some nice momentum to the grind.

Stampede Reels in Buffalo Stack’n’Sync

A full reel of buffalo in Buffalo Stack’n’Sync merges into a Stampede Reel. That giant symbol carries a random multiplier of x1, x2, x3, x4, x5, x10, x15, x20, x25, x50, x75 or x100. It only connects with other buffalo symbols, and if more than one Stampede Reel is part of the win, the multipliers are added together first. When they actually line up, those combined values can be pretty wild.

Free Spins in Buffalo Stack’n’Sync

There are two bonus rounds in Buffalo Stack’n’Sync, both triggered by the flaming scatter symbol. Hitting three scatters awards 10 Free Spins. In this mode the odds of landing Stack’n’Sync symbols are higher, and high paying animals are more likely to appear in stacks. In my sessions the regular Free Spins can be very hit or miss, but a good mix of SNS hits and buffalo stacks can still deliver solid returns.

Landing four scatters triggers Stampede Spins, which is the top feature. Here the reels contain only buffalo, Stack symbols and dead skull symbols. Each time a Stack symbol lands, between 5 and 60 buffalo are added to that reel and skulls are replaced. Fill a reel and it turns into a Stampede Reel as usual. Every Stack symbol also awards one extra spin, so the bonus can stretch out nicely when the symbols co operate.

Bonus Buy in Buffalo Stack’n’Sync

Outside the UK, Buffalo Stack’n’Sync comes with three straightforward bonus buy options. Paying 15x your bet gives one spin with a guaranteed SNS symbol and at least one respin, at around 96.4 percent RTP. Paying 100x buys the regular Free Spins on about 96.46 percent, and 250x buys Stampede Spins on about 96.5 percent. I tend to favour the cheapest buy when I just want a quick few shots at stacked reels.

Our Verdict on Buffalo Stack’n’Sync

I went into Buffalo Stack’n’Sync expecting another standard buffalo clone, and visually that is more or less what you get. The prairie art and animal lineup are very familiar, and it does not have the moody style some other Hacksaw releases carry. Once you get past that, the gameplay combo of Stack’n’Sync respins and Stampede Reel multipliers feels very much like classic Hacksaw design.

This slot is not for anyone chasing gentle, low risk play. The variance is high and the adjustable RTP ranges mean you should always check which version you are sitting on. Sessions where SNS symbols refuse to land can eat a balance fast, and even Stampede Spins can whiff when stacks keep piling onto the same reel without connecting. It can feel quite unforgiving when it behaves like that.

On the other hand, when the game decides to turn up, it can hammer out big hits from nowhere, especially when multiple Stampede Reels drop with total multipliers climbing towards x50 or higher. With max wins of 10,000x your stake and plenty of synergy between the features, Buffalo Stack’n’Sync is a hard bucking, high variance ride that I keep in the rotation when I fancy some wild west animal action.
