Enjoy an expanding grid as you explore the great outdoors in this video slot brimming with beasts and natural beauty. Land combinations of winning symbols to spark cascades and cause the grid to randomly expand with an extra row on the bottom. The grid can continue to expand until you have ten rows and a massive 100,000 ways to win.

How to play Timber Stacks

Take a break from games such as the Cops N Robbers Big Money slot and start your encounter with nature with the help of the following top tips:

  1. Just like many other paid-for and demo slots, one of your first moves is to set your stake by pressing the coin tab. The minimum bet is 0.20 a spin.
  2. The ‘i’ tab opens the paytable, which updates dynamically according to how much you choose to stake.
  3. Always bet sensibly and make use of responsible gaming features if you need them. These include voluntary timeouts and self-exclusions.
  4. The three-bar tab opens the main menu, where you will find settings to allow you to personalize your playing experience.

How to win at Timber Stacks

  • You need to land three to five winning symbols for a prize. 
  • The wolf is the highest-paying standard symbol, adding 10x your stake for a five-of-a-kind combination.
  • The bear will reward you with 4x for five, followed by the 2x win multiplier owl and the 1.5x big cat and fish symbols. 
  • There are also playing card symbols offering up to 1x your stake.

Timber Stacks bonuses

Let's take a look at the Timber Stacks bonus features available to unlock:

Wild symbol

This symbol can substitute for other icons except for the scatter symbol and can land on the central three reels.

Expanding grid

As mentioned at the start of this Timber Stacks slot review, the grid can expand randomly after no more winning combinations form. This gives another row for cascading symbols to fall into and can continue until you are playing on a 10x5 grid with 100,000 ways to win.

Different reels can fall, allowing new symbols and the potential for more winning icons to land. The way the symbols fall into the empty grid positions is dependent on which reels are randomly selected.

Scatter symbol

Like many slots in online casinos, this game has a scatter symbol that can trigger a free spins bonus. Many slots demand that you land at least three scatters to trigger this feature, but Timber Stacks wants you to have at least four anywhere on your grid.

Free spins bonus

You will start with at least eight free spins and you can benefit from the cascades and the randomly expanding grid, just as you can in the base game. You are awarded eight free spins for four scatters and ten free spins for five. 

Max-win 10,000x

Timber Stacks combines colourful and vibrant graphics with the popular tumbling mechanic that allows for more payout potential if new winning symbols fall into place.

FAQs

Is there a free spins bonus in the Timber Stacks slot?

Yes, players must land four or five scatter symbols during the base game to trigger eight or ten bonus spins. During the free spins bonus, there are cascades after wins that could see more winning symbols fall into place. You can also experience a randomly expanding grid onto which different reels can fall and include up to five more symbol positions each.

How many ways to win are there in the Timber Stacks slot?

The standard grid starts with five reels and five rows with 3,125 ways to win; however, this grid can expand and lead you to have the payout potential offered by 100,000 ways to win. The expanding grid feature can trigger randomly after any spin or tumble when there are no more combinations of winning symbols on the reels.

How does the expanding grid feature work in the Timber Stacks slot?

When this feature is triggered, an empty row is added to the bottom of your grid. A random reel is also chosen to fall. If the first or second reels are chosen, symbols will fall from them to the right and fill any empty positions. If the third reel falls, symbols can fall to the left or the right. If the fourth or fifth reels fall, the symbols will fall to the left. After the tumbles end, the grid will return to its standard 5x5 size.
