Theme and Graphics
The protagonist of the slot machine is Kenny, a tin can. The character looks simple and concise. The curious and adventurous tin can has already been featured in one of the manufacturer's games on the menu, like Stack 'em casino. Together with his friend, gray mouse Mona, cheerful Kenny travels through the forest.
It is worth noting the bright visualization of the background of the Stack 'em machine. Gamers expect realistic pictures of nature, endless fields, forests, and mountains. These images contrast with the minimalistic depictions of the main characters.
Stack 'em starts with a cutscene where the title's original font scheme draws in the most. This is followed by a short video tutorial, focusing on the main points of the gameplay.
The background of the Stack 'em slot is presented as a forest location, where there is a lot of free space, and tall trees reach the sky with their branches. Distant mountains are visible in the foggy haze.
In the foreground, the gamer will see the playing field, on both sides of which are the main characters. The top of the Stack 'em interfaces features a logo emblazoned with Kenny's black bowler hat.
During gameplay, the background of Stack 'em can change to a field of golden ears of wheat. A pleasant melody and light animation brighten up the online session: the gambler will enjoy play Stack 'em for fun. The game grid is divided into cells. Under each reel there is a scale with five locks - the player will learn about their purpose later.
How to Play Casino Stack 'em Slot?
The functional panel of the Stack 'em slot machine looks concise. Before starting the gameplay, it is recommended to use the settings system designed to adjust the audio track volume and screen size. The button with three lines opens the paytable, the rules of the machine, and the schemes for constructing combinations. The indicators display the size of the current bet and the balance on the balance.

The online session starts with bidding. To do this, use the "up" and "down" buttons. You can start the rotation of the reels in manual or automatic modes. In the first case, a button with a semicircular arrow will help, in the second - the same small button with two arrows.
In Stack 'em game, there is an opportunity to purchase best slots bonus game round without waiting for it to randomly open. To use it, just click on the corresponding blue button located to the left of the navigation bar.
The goal of the player is to form winning combinations of identical symbols. The combination is created according to the principle of clusters. You will need at least 5 identical characters connected horizontally or vertically.
On the positions of the Stack 'em machine, the following, sometimes somewhat unusual symbols are replaced: a raised finger, an image of a snake, a skull, a dead bird, a monstera leaf, and a set of English letters.
If the gambler does not understand the rules, it is recommended to play Stack 'em demo first.
Stack 'em RTP, volatility, max win
The degree of volatility of the slot machine is high. This indicates the possibility of getting big prizes, even though combinations are rarely formed. The maximum payout of the slot machine reaches x10000 credits.
Stack 'em free spins no deposit and bonus features
The joker of the Stack 'em slot machine traditionally replaces ordinary game elements. Let's also consider the bonus features of the slot and the rules of how to play Stack 'em.
As soon as the player makes a cluster of 5 or more identical characters, all elements will disappear from the field. They will be replaced by new icons that drop down from above. When forming prize combinations, this process is constantly extended.
If a gamer managed to create a stack of certain symbols on any reel, then instead of a lock, a multiplier value will appear under it. It corresponds to the number of symbols that have accumulated (maximum - x6). It is easy to guess that the summation of the maximum multiplier values on all five reels of the Stack 'em slot machine will allow you to reach the maximum multiplier - x30.
The algorithms of the Stack 'em free play have a bonus mode with free spins. Its activation occurs when 3 scatters appear during one cascade. The gamer is given 5 free spins, their number will be shown in the form of hearts above the game grid. During this period, the value of the common multiplier increases. The number of icons in the winning clusters is added to it.
During the bonus mode, two new special signs become relevant. One of them is "x" (multiply). If the winning clusters are located next to it, then the prize amount is multiplied by the total coefficient.
When a character with a question mark appears, you can get:
- from 2 to 5 additional free spins;
- from 1 to 50 to the total multiplication factor;
- multipliers from x2 to x5.
It is possible to purchase the bonus mode of the Stack 'em slot without waiting for it to randomly open. To do this, you need to increase the bet by 129 times.
