Wild Herd Stampede Stacks

Wild Herd Stampede Stacks Review

Wild Herd Stampede Stacks is an adventurous online slot by Infinity Dragon Studios that takes us to the wild frontier. Buffalo charge and stampede up to a massive win potential and unlock various features on the way. Several progression mechanics are active on every base game spin, building up the gameplay for the bonus or triggering a prize hunt with 4 awesome jackpots.

Infinity Dragon Studios is one of the top slot developers building content exclusively for Games Global. It was established in 2018 and it’s part of the GG’s Australian division. Infinity Dragon Studios has released about 40 online slots so far, and some of them made waves in the industry. It is no coincidence that in 2023 the provider was nominated for the “SlotCatalog's Rookie of the Year” award.

Wild Herd Stampede Stacks follows the lead of several other titles released by the studio in 2025: Wild Rhino Stampede Stacks, Wild Stacks Super Spins, and Black Sails Wild Seas. They all come with 5x4 playing boards and 30 fixed paylines, just like the game in the spotlight. You can use the Wild Herd Stampede Stacks demo to test all the features, including Totem Collection, Sticky Wilds, Free Spins: regular and boosted mode, Bonus Game, and more.

Wild Herd Stampede Stacks Slot - Reels Screen

Wild Herd Stampede Stacks pays for 3, 4, or 5 regular symbols of a kind on the active lines, which start from the leftmost reel and continue to the right. Buffalo is a wild symbol, and it substitutes for all the regulars. Wilds land frequently on the grid, as you will quickly notice, and they pay the highest cash rewards if lined up. Buffalo, Mustangs, and Eagles fall in the category, and they are the only symbols to pay for 2 of a kind as well: award 0.10x, 1x, 2.50x, and 10x the bet.

Wolves award from 0.60x to 4x, Rattlesnakes - 0.40x to 2.50x, while the low-value card royalties, As, Ks, Qs, Js, and 10s pay between 0.20x and 2x the bet. Several bonus symbols are also in play and are linked to several special features, but they do not deliver instant cash. The betting range is not particularly wide and strategy-friendly, but you can still use 12 stake tiers between €0.20 and €25 per spin.

The Wild Herd Stampede Stacks RTP rate is the highest compared to the other online slots I already mentioned - 96.31%. And it is not far from the highest payout rate I’ve seen in the provider’s collection - Gods & Pyramids Power Combo (96.86%). The online slot is characterized by high levels of volatility and boasts a Hit Frequency rate of above 30%. The Wild Herd Stampede Stacks max win is a rumbling 10,000x the bet.

Wild Herd Stampede Stacks Features

Wild Herd Stampede Stacks offers feature-rich gameplay with several genre lines running at the same time. It is crucial to remember that the progress on the Totem Collection Meter and Super Free Spins Meter is saved per bet level. It won’t be lost, but that will surely affect any progressive betting strategies. The other special features are Stampede Stacks, Frontier Fortune Bonus Game, and Free Spins. Find out all the details in the following paragraphs:

Golden Buffalo Totem Collection

Golden Buffalo Totem is a special symbol that can land on any position and will be collected in the respective reel’s meter beneath the grid. These figures can appear only during the base game and are linked to the core Stampede Stacks feature. You will need 4 collected symbols to start it, and Golden Buffalo Totems do not follow on Stampede Stacks reels.

Stampede Stacks Feature

Stampede Stacks is only active in the base game and activates on every reel separately, as I explained above. On activation, a Wild Buffalo is added to the respective reel on every spin until a full stack is in view. Until then, all placed Wild Buffalo are sticky and remain in position. If Stampede Stacks is activated on 1 or more reels, the progress is also saved per bet level. Once a full stack is in view, it will be removed during the following spin and the Golden Buffalo Totem Meter for that column will be reset.

Free Spins & Super Free Spins

Land 3, 4, or 5 scatter symbols at the same time to trigger the Wild Herd Stampede Stacks bonus round with 5, 7, or 10 free spins. The minigame starts with a multiplier of x1 displayed above the reels and applicable to all wins. On every free spin, a Wild Buffalo will be added to a random position, and it will become sticky. Moreover, the win multiplier will be increased by +1 up to x10.

Super Free Spins Meter is available in the base game, and you will add one point to it every time 2 scatter symbols land. Every 4th collected point will increase the Meter by +1 to a maximum of x5. Once you complete the trail and on the next bonus trigger, you will get 5, 7, or 10 super free spins for 3 to 5 scatters. The boosted mode will start with a win multiplier of x5, but it’s still limited to x10. Scatters continue to land during both bonus modes, so Free Spins are retriggerable.

Frontier Fortune Bonus Game

Bonus Coins may appear as overlay symbols on any regular during the base game and will be collected in the Money Bag on the right. The animation effects of that action are for fun only and do not actually contribute to the Symbols Collection mechanic. On any collection and 100% randomly, the Frontier Fortune Bonus Game may activate.

Sadly, it seems that if you get it along with Free Spins or Super Free Spins on the same spin, you will get only the wager-free rounds. So, let's keep our fingers crossed to get the bonuses on separate spins. The minigame starts with 12 loot bags on the screen and 3 picks.

Some of the bags hide increments to the jackpot prizes and other cash rewards. If you hit a jackpot piece, you’ll win an extra pick. If you hit a cash prize, you lose a pick. The bonus ends when all picks are used, and you'll get the sum of all cash and jackpots won so far.

• Grand Jackpot - 10,000x the bet
• Major Jackpot - 200x the bet
• Minor Jackpot - 40x the bet
• Mini Jackpot - 15x the bet

Theme & Graphics

Wild Herd Stampede Stacks is the first Buffalo theme in the provider’s slot portfolio, and it brings the action to the North American wilderness. Red rocks, high skies, eagles, rattlesnakes, and buffalo during the day and ferocious wolves during the night. The online slot stands out with premium graphics, smooth animation effects, theme-related sounds, and adjustable voiceover.

Wild Herd Stampede Stacks offers different settings in the bonus modes, like a skeleton propped against a tree. It holds a rifle and guards an abandoned caravan, for eternity. As usual for Infinity Dragon Studios, the game is fully compatible with mobiles, Android and iOS. It is averagely fast even through the Quickspin and Turbo Spin, but leaves a good taste even after a few spins.

Wild Herd Stampede Stacks Free Play

If you feel ready to meet the stampeding beasts, activate the Wild Herd Stampede Stacks free play mode. A link is available above the list of verified casino sites that will lead you to the demo. As always, it comes with no strings attached and no time limits. Here at SlotCatalog, we strive to assist our readers with expert reviews, but also free trials. This might not be the best title for progressive betting strategies, but it is always a good idea to have a few demo spins before switching to real oney play!

Pros And Cons Of Wild Herd Stampede Stacks Slot

Our Verdict

Wild Herd Stampede Stacks offers a power-stacked slot experience with numerous wilds, progressions, jackpots, and free spins. It builds a similar atmosphere to Wild Rhino Stampede Stacks, but copies the mechanics and features from this game and at least 2 others: Wild Stacks Super Spins and Black Sails Wild Seas. Moreover, it copies the loose ends as well!

You will lose the Frontier Fortune bonus if you trigger it along with any Free Spins mode, just like you’ll lose Stampede, Gold Bar, and Cutlass Battle Bonus in the slots mentioned above. Moreover, the win multiplier in FS and SFS is limited to just x10, which combined with a potential retrigger is weaker than expected. Even so, the technical specs of the game are good: 96.31% and a max win of 10,000x.

Wild Herd Stampede Stacks might not offer groundbreaking mechanics, but Infinity Dragon Studios never disappoints regarding quality. The online slot looks, sounds, and feels great, even if the features feel overused and repetitive. Moreover, the combination is worth recycling, given the player's sense of progression on multiple levels. So, if you like the American wilderness as a theme, this slot game could be a good choice for a Sunday afternoon!
