Buffalo Stack ‘n’ Sync Slot Review

It seems that the theme is everything as usual: prairies, bison, the familiar atmosphere of "Buffalo" slots. But Hacksaw Gaming took a different path — instead of a simple copy of the classics, they focused on their signature feature Stack 'N' Sync. This mechanic allows you to completely "catch" an entire reel with the same symbols and then synchronize it with others, which sometimes leads to truly epic combos. I was especially pleased that the bonuses here fall out not only through the usual Free Spins, but also thanks to random synchronizations that can happen at any time.

The slot was released in the summer of 2022 and immediately became popular among those who appreciate a combination of non-standard solutions and familiar themes. By the way, against the background of other Hacksaw releases, this game looks more "family-friendly": there is a little less aggression and more chances for a long series of winning spins even in the main game. But at the same time, the potential is still very high - the slot does not turn into a "light" version of the classics.

The base game is built on a standard 5×4 grid with 10 fixed paylines. The symbols move as usual, but the whole point is in the Stack 'N' Sync function. At any time, a special S'N'S symbol can appear on the reels, which completely fills the entire reel with one symbol. After that, synchronization starts - other reels can also become completely identical, which significantly increases the chances of a big win. Sometimes this leads to repeated respins, and sometimes to random large combinations even before the bonus game is activated. Everything happens dynamically, so the usual spins do not let you get bored: you never know when the next "stack" will fall out.

The main bonus is Free Spins, which are triggered if you collect three or more Scatter symbols. In the bonus mode, Stack 'N' Sync works even more often, increasing the chances of a "full screen" of identical symbols. Every time the S'N'S symbol appears, you can expect several reels to synchronize in a row — and this is where the maximum big wins are most often caught.

An important feature: there is a Bonus Buy function, which allows you to buy an entry to the bonus round. Moreover, there are options with different chances of getting top symbols (the more expensive the bonus, the higher the probability of catching a large combination). In addition to free spins, sometimes there are random respins with cup reels right in the base game - which adds excitement even to those who do not like to wait for the bonus.

The paytable is built around wildlife: the top symbol is Buffalo, it brings the biggest wins, followed by Eagle, Wolf, and Deer. The special S'N'S (Stack 'N' Sync) symbol is responsible for synchronizing the reels and landing large combos. Scatter triggers the bonus game, Wild helps to collect paylines by substituting standard symbols. Small payouts are the letters of the cards that simply maintain a balance between big wins. If several Buffalos with synchronized reels enter the respins or bonus, you can really catch a solid x.

The maximum win is declared at x10,000 of the bet. Theoretically, this is achieved if you manage to catch a full Buffalo screen with synchronized reels and a good multiplier in the bonus game or during a respin. In practice, such situations are rare, but the chance of a serious payout here is felt in almost every bonus round or even in a regular game. Volatility is high — there are both empty sessions and moments when the slot "pours" several good combinations in a row at once.

The graphics in Buffalo Stack 'N' Sync are nice and colourful, without overloading with details. The symbols are clear, the animations are smooth, visually everything resembles a high-quality cartoon. The sounds are a mix of nature, drums and light music, which is not annoying or distracting. The effects of big wins are bright, but not too much: the win is felt, but does not turn the slot into acid fireworks. The optimisation is excellent — everything spins quickly on a phone, tablet, and PC.

Buffalo Stack 'N' Sync is perfect for those who love the classics with wild animals, but are tired of banal "Buffalo" slots. It will especially appeal to those who appreciate unexpected bonuses, chips with respins and the opportunity to catch several top symbols at once at one moment. The slot is dynamic, reckless, but not oppressive - even with a long series of empty spins, the game does not get boring.

The volatility of Buffalo Stack 'N' Sync is high, so it is better to choose your bets wisely — 2-3% of the bankroll per spin is optimal. If you want to try Bonus Buy, take it only in the "long run", since bonuses do not always pay off. The default RTP in the slot is 96.36%, but there are versions with a reduced RTP (up to 94.32% or even lower) - be sure to look at this figure before starting the game. For auto-spins, set limits, otherwise you can quickly be left without balance on a series of unlucky spins.
