Timber Stacks Slot Review

Timber Stacks Slot Overview

Timber Stacks sees top online developer Pragmatic Play take a walk on the wild side in the beautiful American mountains. A cast of local wildlife joins in the action in a game which offers a thoroughly soothing experience. The shout of “Timber” is no doubt dreaded by all trees. However, the falling oaks of the reels represent the most distinctive feature of a game offering an expanding grid mechanic and a rewarding Free Spins Bonus. Get on the right sight of this animal kingdom, and you may emerge with a 10,000x max win!

Pragmatic Play can be relied upon to produce a good-looking slot and have delivered another visual beauty. The theme may not be particularly action-packed, but it’s sometimes nice to settle down into the slot's scenery, and this game does it better than many similar titles. It’s also refreshing to see a developer introduce something a little different in the gameplay, and the falling reels and expanding grid do a great job of keeping things interesting in the base game, before really being given their chance to shine in the tumble-tastic feature. For a chilled-out and potentially rewarding session, this is well worth a look.

Timber Stacks Slot Features

Tumble Wins

Following any win, all winning symbols will disappear, with the remaining icons falling to the bottom of the reels and new symbols dropping in to fill the gaps. This process repeats for every winning combination – leading to exciting chain-reaction wins!

Mountain Wilds

May appear only on reels two, three, and four and substitute for all standard symbols to help create winning combinations.

Expanding Grid

This feature may kick in at the end of any spin or tumble which does not produce a win. A new row of blank symbols will appear below the grid, with one of the reels randomly selected to topple over and fill the empty spaces with its symbols. New Symbols drop in to fill the vacated reel. The reels topple over in different directions, as follows:

  • Reels one and two: Always fall to the right
  • Reels four and five: Always fall to the left
  • Reel three: Falls to the right or left at random

This feature may activate up to five times during a tumble sequence, leading to a possible 5x10 grid and a bumper 100,000 winning ways!

Ante Bet

Selecting this option from the left of the reels will increase the cost per spin by 25% but boosts your chance of triggering free spins.

Free Spins Bonus

Green Pawprint icons act as the Scatters of the game.

  • 4x Scatters = eight free spins
  • 5x Scatters = 10 free spins

Whilst not stated in the rules, we found that the collapsing reels occurred on every spin during the feature. At the very least, you can expect to be hollering “Timber!” far more frequently during the Free Spins Bonus.

Bonus Buy Feature

If you can’t wait for those Green Paw Prints to plod into view, Bonus Buy is available in eligible jurisdictions (not available to UK players). Priced at 120x the total bet, selecting this option will take you straight into a randomly activated four or five-scatter Free Spins Bonus.

Our Verdict The expanding grid and falling reels are easily the most engaging aspects of this release. As such, it is satisfying to see the mechanic take centre stage in the bonus round. An ever-increasing layout, in combination with the tumble wins system, can lead to impressive winning sequences, which make the round well worth the wait!

Timber Stacks Slot RTP & Volatility

Variable RTP

The top-end 96.50% Return to Player (RTP) percentage is the tip of a Cougar’s tail above the industry average RTP of 96%.

Despite the tranquil vibe, the math model takes this game firmly into the high volatility category. As such, you should expect your fair share of ups and downs. On the plus side, games of this rating offer a better chance of hitting a big win in a short session than low-medium-volatility releases.

Our Verdict An RTP of 96.50% compares favourably with the industry average and represents solid value for money. However, you should be aware that alternative, lower settings of 95.60% and 94.50% are also available. Both are still reasonable, but it is worth consulting the information section of the game to discover the setting in use at your online casino of choice. With the fish appearing to be the most fearsome animal on show, the theme doesn’t scream high volatility. Nevertheless, given the decent win potential and turbulence on offer, the setting feels about right.

Timber Stacks Slot Graphics & Audio


Top marks to the visual team for creating a beautiful, naturalistic backdrop. Grass sways in the breeze, leaves blow by, birds swoop, and critters gallop through the reeds. All of which lend an engrossing, dynamic element to the scenery. The animals on offer are classically illustrated and bring further life to the reels with their win-celebrating animations.

The ambient theme provides the perfect accompaniment to a stroll through the woods and meadows. Serene strings slowly swoop in the background, pipes dance in and out of focus, whilst a strummed guitar and gentle drums provide the beat which drives the action. The reel effects are all nicely done, with splashing fish, hooting owls, and roaring bears joining in with the electronic chirps and twinkles.

Our Verdict If a traditional take on the wildlife theme is your thing, you will likely love what you find here. The backdrop and symbols are all impressively illustrated and combine to a relaxing effect with the soothing soundtrack.
