Buffalo Stack’n’Sync Slot RTP, Details & Wager Limits

Reels/Paylines: 5 reels + 10 paylines

Stakes Range: 10p to £100 per spin

RTP: 96.36%

Max Win: 10,000 x bet per spin

The Buffalo Stack’n’Sync slot is played on 5 reels, 4 rows, and has 10 fixed paylines. Wins are paid if the same symbol or wild appears along 1 of the 10 fixed paylines from left to right, beginning from the leftmost reel.

Stakes range from just 10p up to £100 per spin, thus catering to all players from low to high stakes. To change your total bet, simply use the arrows to the left of the spin button below the reels. Autoplay is also possible in most territories outside the UK, and you can set loss and win limits here with the autospins.

The Buffalo Stack’n’Sync RTP is a healthy 96.36%, which is above the 96% average for an online slot and typical of a lot of Hacksaw slots. This percentage was calculated by simulating 10,000,000,000 rounds. The hit frequency is set at 20.20%, which means that just over a 5th of all spins on average will result in a winner.

The maximum win is 10,000 x your stake, which is a typical figure you’ll come across with a lot of Hacksaw games. The Stampede Spins feature is your best chance of landing this as you can get up to 60 Buffalo symbols on the reels for potentially huge wins.

Theme – a buffalo bonanza

Theme: Wildlife

High Value Symbol: Cactus

Compatibility: Mobile, Tablet, Desktop

buffalo-stack-n-sync-slot-base-game

This slot is set in the Great Plains of North America on a mountain top alongside a bunch of cacti, which is in fact the Wild symbol in this game. The graphics are sharp and the colourful symbols make the reels appealing to the eye on both desktop and mobile devices.

One thing Hacksaw always does really well is to attach good sound effects and a good soundtrack to its slots. The Buffalo Stack’n’Sync is no different. It takes a feature to get going as it’s initially just a guitar playing a few strings in anticipation. But the bonus features bring out the best in this game with superb sound effects and visuals as the reels spin.

On the reels, the lower-paying symbols are your A-10 royals. The higher-paying symbols are made up of horses, cougars, wolves, eagles and buffalos. The Buffalo is the highest paying symbol, giving you 3, 6 or 20 x your stake for 3, 4 or 5 in combination.

The Wild in the game is a cactus, which substitutes for all standard symbols and can pay 20 x your stake for 5 on a payline. Here’s a list of the symbols in the game:

Buffalo Stack’n’Sync Mobile

buffalo-stack-n-sync-mobile-slot

With Hacksaw Gaming creating all slots using HTML5 technology, the Buffalo Stack’n’Sync mobile slot is available to play on all iOS and Android devices. The 5×4 layout works really well on smaller screens, especially in portrait mode.

Buffalo Stack’n’Sync Bonus Features

There are 5 bonus features to enjoy in the Buffalo Stack’n’Sync slot game. The Stack’n’Sync symbol does exactly what it says on the tin – stacks paying symbols on the reels for potentially big wins. You’ve also got Stampede Reels, Free Spins and a Stampede Spins feature. Let’s explain how they all work for you.

Stack’n’Sync feature

Landing Stack’n’Sync symbols will stack any paying symbol on the reels. A stack of 60 symbols will fill the entire reel. If you fill the whole reel with the same symbol and sync all reels, it can lead to big wins.

The reels where Stack’n’Sync land will be filled randomly with 15, 30, 45 or 60 symbols of 1 kind. 1 respins is awarded for each Stack’n’Sync symbol that lands too, with additional symbols landing during the respin syncing to the already stacked reels.

Only 1 Stack’n’Sync symbol can land on each reel in a round

Stampede Reels

When a full reel of buffalo symbols land and at least 1 is part of a winning combination, the Stampede reel is activated with a multiplier of up to 100x. This multiplier will apply to any winning payline with Buffalo symbols that connect to the Stampede reel.

If more than 1 of the symbols on the Stampede Reels is part of a winning payline, the multiplier values will be added together. The possible multiplier values are 1x, 2x, 3x, 4x, 5x, 10x, 15x, 20x, 25x, 50x, 75x and 100x.

Free Spins feature

buffalo-stack-n-sync-slot-free-spins-feature

Land 3 Bonus symbols in the base game of the Buffalo Stack’n’Sync slot to trigger this Free Spins feature. You will receive 10 free spins and the odds of landing the Stack’n’Sync symbol increase.

Statistically, higher-paying symbols are more likely to land here than lower-paying ones, which increases the chance of triggering a large stack of Buffalo symbols for potentially big wins.

Stampede Spins feature

buffalo-stack-n-sync-slot-stampede-spins-feature

4 Bonus symbols in the base game will trigger the Stampede Spins feature with 10 free spins. This bonus round will replace the normal reels with reels that only have non-paying skulls and Buffalos.

Every time a Stack symbol lands on 1 of the reels, 5-60 Buffalo symbols are randomly added to that reel to replace the Skull symbols.

1 extra free spin is awarded for every Stack symbol that lands in the bonus feature

Bonus Buy feature

In most territories outside the UK, you can buy the Bonus features for a certain price:

Option Cost RTP
Stack’n’Sync symbol + 1 respin 15 x bet 96.4%
Free Spins feature 100 x bet 96.46%
Stampede Spins feature 100 x bet 96.5%

Originality








The Buffalo Stack’n’Sync slot is another solid release from Hacksaw Gaming, and all of the action comes in the bonus features. You don’t need to trigger anything special initially either as you can enjoy a few features in the base game, which is great to see. Not all slots offer base game fun, so Hacksaw gets some brownie points here.

The 100x multipliers with the Stampede Reels feature is generous. You can even get multipliers added together for even bigger wins if more than 1 of the Stampede Reels is part of the same winning payline, which all adds to the overall appeal of the slot. Some players want ample opportunities to land big wins and this slot dishes out those opportunities in abundance.

Overall, the variety in the gameplay and the sophistication of the Buffalo Stack’n’Sync slot as a whole will attract many players. I enjoyed the Stampede Spins feature, which is where the largest wins will probably be, but be aware of the 20.20% hit frequency and don’t expect huge wins too often in this highly volatile game.

If you’re a fan of the theme, check out a couple of other Buffalo-related slots with huge win potential. Buffalo Rising Megaways from Blueprint Gaming has up to 117,649 ways to win and max wins of 50,000 x your stake. Alternatively, Buffalo king from Pragmatic Play could see you land max wins of a whopping 93,750 x your stake!

With multipliers being a major part of a lot of Hacksaw slots, check out Chaos Crew. This game is loaded with numerous multipliers on a 5×5 grid.

Pros
  • 10,000 x bet max wins
  • Multipliers up to 100x
  • Above average RTP
Cons
  • Highly volatile (4/5)
