Timber Stacks Slot


Sharing is caring!

Our rating:
  • A new Pragmatic Play with a nice Arctic theme
  • Non-winning spins can lead to extra rows
  • Nothing special about the free spins bonus

Timber Stacks is a new slot from Pragmatic Play and it offers a brand new mechanic of sorts, creating additional positions on some non-winning spins and tumbles, but I’ll discuss this all in more detail later. It comes with a frosty arctic theme that looks nice, and the reels are each stacks on timber which makes sense when you understand how the game works. There are 5 reels and 5 rows to start with. You just need a winning combination from left to right using the following base symbols, ranked in ascending order based on their value:

  • 10, Jack or Queen
  • King or Ace
  • Fish or Mountain Lion
  • Owl
  • Bear
  • Wolf

Timber Stacks Slot Bonuses and Features

Wild Symbol. Shown as a mountain, this symbol will substitute for all others in a winning combination apart from the scatter symbol. It can only appear on reels 2, 3 and 4.

Tumble Feature. This is common mechanic found in many slots. Winning symbols are removed from the reels, allowing new ones to fall in from above. If this create more wins, the same will happen and this continues until there are no more wins, all within the same spin.

Grid Size. If there are no more wins after a spin or tumble, the grid size feature can trigger. One or more empty rows are added to the bottom of the grid and a random reel will fall to the bottom. This creates space for more symbols to fall in to the new, empty positions, potentially creating more wins and tumbles.

Free Spins Bonus. To trigger this you need to land 4 or 5 scatter symbols anywhere on the screen at the same time. This will give you 8 or 10 free spins, respectively. During the bonus, the grid size feature is still available, though not guaranteed to trigger on every non-winning spins as we expected.

Bonus Buy. This is available in some regions, where you can buy the bonus for 120x your stake, giving you 4 or 5 scatters and the 8 or 10 free spins, respectively.



Timber Stacks slot from Pragmatic Play attempts to bring a new mechanic to the industry, and I can’t quite decide how I feel about it. It’s a new way of creating additional wins using tumbles, and it’s fairly straightforward but I’m not sure how effective it really is. I do like how it ties in with the theme do as you cut down timber. I think I would have enjoyed this slot more if there was more to the free spins bonus. As far as I can tell, it plays just like the regular game , and given that in some regions it costs 120x your stake, this seems rather odd and surprising. Overall, I like that they’re trying something new here and this new mechanic could have potential, but I don’t think that potential has been fully realised in this game so hopefully they’ll bring out others in the future where it works a bit differently.
