Timber Stacks Review

The invisible grid suits the theme of this game well, and it also gives you more complete glimpses of the pristine alpine landscape in the background. Each symbol lands with a wooden backdrop, meaning that each reel is literally a stack of timber. The title Timber Stacks therefore fits the bill, and the big innovation is that these timber reels can collapse to fill added bottom rows with symbols in different ways. This is how the grid gets expanded, and it can happen up to 5 times per tumble sequence.

This means that 5 extra rows can be added, and the collapsed reel is filled with new symbols dropping from above. This happens on a somewhat regular basis in the base game, but we got it far more frequently in the bonus round. The number of win ways increases to 100,000 on a maxed-out grid, and you can win up to 10,000x your stake. Nothing much else is going on, however, and the base game can drag on for a long time if you, for whatever reason, are unable to activate the ante bet.

Pragmatic Play - Slot Developer

Pragmatic Play is one of the most productive developers in the industry, and they have been around since 2015.

With over 420 video slots to their name, it’s safe to say that this is a veteran developer. Wolf Gold is one of their most popular releases, and the wolf plays a central part in Timbre Stacks slot as well.

Slot Theme And Storyline

Lumberjacks scream “Timber!” to warn each other about falling trees, and in this game you get collapsing timber with no warning. The alpine setting could hardly be more idyllic, and the more symbols that are removed via the tumble mechanic, the more of the stunning backdrop becomes visible. Animated wildlife can be spotted in the background as well, but the animals move in repetitive loops that trigger a bit too often.

Timber Stacks RTP, Volatility, And Max Win

The top-tier Timber Stacks RTP of 96.5 % is well above the industry average. Be aware, however, that operators can adjust the RTP down to 95.6 or 94.5 % as they see fit.

This game scores 5 out of 5 on the in-game volatility scale, which is typical for Pragmatic Play, and you can therefore expect fluctuations on your bankroll. The Timber Stacks max win of 10,000x is above average, and it comes with a 1 in 14,326,648 spins hit frequency.

Timber Stacks Rules And Gameplay

Timber Stacks slot pays out on a 5x5 grid with 3,125 default win ways. You win by landing matching symbols anywhere on 3 to 5 adjacent reels starting from the leftmost reel, and the grid can expand to 5x10 with 100,000 win ways. You can play with bet levels between £0.2 and £240 per spin, which is a solid range that should suit most player types. Wilds substitute for any pay symbol to help complete and/or improve wins, and scatters trigger the bonus round.

Timber Stacks Bonuses And Special Features

Timber Stacks game revolves around the innovative Increasing Grid Size feature, and it can prolong tumble-winning streaks at random times. It will expand the grid to give you up to 5 extra rows, but you only get one added row per trigger.

Ante Bet (not UK)

Eligible players will find the Ante Bet option on the left-hand side, and keeping it on means you pay 25 % extra per spin. The benefit is that your bonus round chances are doubled, from 1 in 439 spins to 1 in 219.5 spins on average. The RTP is not affected either way.

Tumble Wins

All winning symbols are removed from the grid each time via the Tumble mechanic, and the gaps are filled by new and existing symbols dropping down.

This process repeats as long as you keep winning, which means your winning streak can go on indefinitely per winning round.

Increasing Grid Size

The Increasing Grid Size feature can trigger at random times when you land a non-winning spin in a tumble sequence. An empty row is then placed at the bottom, and a reel is chosen randomly to collapse and fill this bottom row. The positions of the symbols filling the bottom row depend on which reel is chosen to collapse, and new symbols will drop from above to fill all remaining empty positions. It’s possible to add as many as 5 extra rows this way, which gives you 100,000 win ways. Everything resets when the tumble sequence ends.

Timber Stacks Free Spins

You need 4 or 5 footprint scatters in view to trigger the Timber Stacks Bonus Round, and this gives you 8 or 10 free spins, respectively. The feature plays out like the base game with nothing extra added.

That being said, the Increasing Grid Size feature did seem to trigger more often than in the base game. This is not explicitly stated anywhere, but rather based on our experience with the game.

Timber Stacks Bonus Buy (not UK)

Eligible players will find the Bonus Buy option on the left-hand side, right above the Ante Bet sign. Purchasing the main attraction will set you back 120x the stake, and this gives you 4 or 5 triggering scatters on the spin that follows. The RTP remains the same as for regular play.

The 200 Spins Timber Stacks Online Slot Experience

You get to see the Increasing Grid Size feature in the base game, before we purchase and trigger the Bonus Round at 0:22 into the 2:42-minute highlights video. The feature gave us plenty of increasing grid size action, and you can see for yourself how we fared by hitting the play button below.

Review Summary And Verdict

The snowcapped alpine mountains scenery is certainly breathtaking enough, and we like that you get to enjoy glimpses of it as symbols are removed from the otherwise invisible grid. The wildlife animations become repetitive pretty soon though, and some more randomness to the movements of the animals would’ve been appreciated. These are minor details, of course, and overall Timber Stacks slot is another playable game from one of the most prolific developers in the industry.

The animal symbols come with cool winning animations, and day shifts to snow-covered night in the bonus round.

The Increasing Grid Size feature will many times not amount to much in the base game, but it’s a satisfying feature to behold nonetheless. It seems to trigger far more often in the bonus round, and this is where you’re most likely to experience a maxed-out grid. The 10,000x potential is solid, but it can take a while between bonus rounds without the ante bet. We don’t see an instant classic here, and we hope follow-up releases come with more features built around this innovative mechanic.
