Buffalo Stack ‘n’ Sync (Hacksaw Gaming) – Review & Demo Play

Buffalo Stack 'n' Sync Slot Review

I’ve spent plenty of time on Buffalo Stack 'n' Sync, and it’s classic Hacksaw under a Great Plains skin. The setup is 5x4 with 10 fixed paylines, wins from left to right on 3 to 5 of a kind. Volatility sits high, roughly a 4 of 5 feel, with a variable RTP that peaks at 96.36 percent. Stakes run from 10p to £100, and the cap is 10,000x. It’s a clean, punchy package where features do the heavy lifting.

Base Game and Features in Buffalo Stack 'n' Sync

Base play is straightforward. You connect lines, and the cactus Wild helps by subbing for any pay symbol. Five Wilds pay like the top bison. The pace with turbo is brisk, which suits the game’s hit-and-miss rhythm. Under the hood it’s about building stacks and lining up animals, with wolves, eagles, cougars and horses joining the bison. When lines land, those mid and high symbols do the work, and stacked screens can appear if things go your way.

Stack 'n' Sync symbols kick the engine into life. One SNS loads its reel with 15, 30, 45 or 60 of a chosen symbol and grants a respin. Land more SNS and new reels sync to the existing stack while more respins queue. Full stacks of buffalo merge into Stampede Reels that carry multipliers from x1 up to x100. Buffalo only link to buffalo, and if you land more than one Stampede Reel, those multipliers add together before the payout.

Wilds and Scatter Symbols in Buffalo Stack 'n' Sync

The paytable is clear. Lows are 10 to Ace and pay 2x to 4x your bet for five of a kind. Highs are horse, cougar, wolf, eagle and bison, paying 10x to 20x for a full line, with the cactus Wild matching the bison’s top line value. Flaming scatter symbols are the tickets to bonus play, and you’ll see skull symbols only during Stampede Spins. It’s a tidy animal set that makes stacked reels easy to read when they land.

Free Spins in Buffalo Stack 'n' Sync

Three flaming scatters award 10 free spins. In this mode, the odds of landing Stack 'n' Sync are raised, and the game weights stacks toward the premium animals. That shift helps you set up buffalo stacks and the Stampede Reels that follow. I’ve had sequences where repeated SNS hits chained respins into lines across synced reels, which is where the slot feels at its best. It’s still swingy, but the momentum can build in a way the base rarely does.

Four bonus symbols trigger Stampede Spins. Here, the reels carry only buffalo, Stack symbols and dead skulls. Each Stack symbol drops 5 to 60 buffalo onto its reel, replaces skulls and adds one extra spin. Fill a reel with buffalo and it converts to a Stampede Reel, and those multipliers can climb quickly if several line up. The round can stall if stacks favour the same reel, yet when the spread is kind, it throws out chunky totals.

Bonus Buy in Buffalo Stack 'n' Sync

Where available, the Buy Bonus menu offers three routes. Pay 15x the bet for a round that guarantees an SNS symbol and at least one respin, with RTP around 96.4 percent. Pay 100x for standard free spins at roughly 96.46 percent RTP. Pay 250x for Stampede Spins at roughly 96.5 percent RTP. I’ve found the 15x entry appealing when I want quick shots at stacks without committing to a full feature, while the 250x option is pure high-variance.

Our Verdict on Buffalo Stack 'n' Sync

The visuals sit in that familiar prairie style, more functional than flashy, but the mechanics carry the session. The core loop is simple when you break it down. Land SNS, pack reels with one symbol, sync more reels, then hope those stacks turn into buffalo and multipliers. With only 10 lines, clean connections hit hard when they arrive. The variable RTP is worth checking in the help screen, as some versions run lower than the top setting.

As a player, I rate it a hard-bucking slot that can go cold for spells and then flip in a handful of respins. The ceiling is 10,000x, and the Stampede Reels are the real driver of anything eye-catching. I dip in for that SNS flow, and when it chains, the game feels great. When it doesn’t, it’s a quick lesson in variance. If you like volatility with a clear route to power spins, this one earns a seat.
