This Pragmatic Play slot offers a 5x5 grid with the great outdoors in the background. There are two crucial features to check out on the left side of the grid- the Buy Bonus and Ante Bet- which I’ll explain below. Timber Stacks slot machine boasts ten paying symbols, plus the Wild and the Scatter, which appear anywhere on the screen. There are five high-paying symbols, with the Wolf and Bear as the most rewarding, paying up to 10x and 4x the bet. Playing card suits are the game’s low pay, which awards you up to 1x the bet. There’s a Wild that helps create a winning combo and lands on reels 2, 3, or 4 only.

Payouts start by landing a three-of-a-kind, and its random spins become exciting with the use of the Tumble Feature. After each winning combo, the game pays all winning symbols, and they disappear to make way for new ones.

Also, the game’s grid size increases, which triggers randomly after a losing spin. When it happens, the game adds another row at the bottom, and a random reel is picked to fall to the bottom. The ‘increasing grid size’ randomly triggers the base game and the bonus round.

Timber Stacks slot machine offers an interesting grid design and mechanic. Initially, there’s a 5x5 grid with up to 10,000 paylines, and it randomly expands during gameplay to add more win lines.  Bigger wins in this Pragmatic Play slot become possible when unlocking the following features:

• Tumble Feature — in this mechanic, winning symbols are paid out first and removed from the grid to make way for new ones. The tumbling of symbols continues until no more winning combos are on the screen.

• Free Spins — land 4 or 5 Scatters to start the bonus and collect 8 or 10 free games, respectively. Special reels play during the bonus, and the Increasing Grid Size becomes active.

• Ante Bet — players have the option to select their bet multipliers. For example, a 25x bet multiplier increases the chances of landing Scatters and triggering the Free Spins.

• Buy Bonus — use this feature to instantly unlock the bonus round for a cost of 120x the current bet.

I like playing the Timber Stacks demo slot not just for its visuals but its wide betting range. Bets in this slot range from 0.20 USD to 240.00 USD, with an option to play the maximum bet instantly. Big wins may randomly come from one of the five regular symbols- the Wolf, Bear,  Owl, Cougar, and Fish. Landing a five-of-a-kind pays anywhere from 1.5x to 10x the stake. The Mountain Wild helps you collect more winning combos as it replaces other symbols, except for the Scatters.

Timber Stacks by Pragmatic Play is a high-volatility game, and the slot’s hit frequency is 20% in my tests. The game’s maximum payout is at 10,000x the bet, and I think it becomes possible through multiple tumbles with the help of the increasing grid size and Wilds. In my experience, payouts are rare, and collecting a series of big wins is difficult.

Timber Stacks follow the template of many Pragmatic Play casino free play slots with engaging mechanics, solid math, and features.  You’ll find 10 regular symbols, with the Wilds and Scatters randomly falling on the 5x5 grid. For those who’ll play Timber Stacks for free, the wins start by forming at least three matching symbols from the left, which is made exciting by the Tumble feature and Increasing Grid Size mechanic. To start a game, follow these steps:

1. Check out and open Timber Stack’s free demo on our site.

2. Select your stake per spin by clicking the ‘-’ and ‘+’ buttons beside the ‘Spin’ button at the bottom-right part of the screen.

3. Indicate your preferred bet and coin value to set the Total Bet.

4. Click the ‘Spin’ button to start playing this game. If you match at least three symbols from the left, according to the paytable, you collect a payout!

When playing this free Timber Stacks slot, you can also use its ‘Bet Max’ button, and there’s an ‘Autoplay’ option if you want to set several spins in advance. On the left side of the grid are two more crucial buttons: a Buy Option at 120x the current bet and the Ante Bet, which increases your bet by 25%.  Using the Ante Bet increases your chances of landing Scatters, boosting the chances of entering the bonus.

As part of the review, I played the Timber Stacks slot in the demo, with 100 spins and 1 USD as the default bet. On paper, it’s a high volatility slot, with some published reviews saying that its hit rate is 1 in 4, and for the bonus, it's 1 in 439 spins.

The game started slow, and it was only during the 7th spin that I hit the first payout, at 3 USD. Then, small wins trickle during the next two dozen spins and earn up to 4.40 USD during the 31st spin. Also, this was the first time the increasing grid size became active. And on my 39th spin, I managed to land 5 Scatters on the grid to reveal the bonus round with 10 free spins.

I noticed here that the increasing grid size feature is more frequent, thus offering plenty of opportunities to extend the win streak and payouts.

At the end of the round, I earned 57.40 USD, which is not bad for a 1 USD base bet. The rest of the demo spins did not produce significant wins, truly validating that it’s a high-variance game requiring a bigger bankroll.
