Space Stacks Online Slot

Space Stacks Slot Game Review

Space Stacks by Push Gaming is a slot machine inspired by space. Such a theme has been selected because users love it. The background music is a simple polyphonic tune; there are no songs.

The base game has no lines and reels on the main field. After loading, the screen shows a 10×10 matrix. The minimum bet per spin is 0.1 USD (or equivalent in other currencies). The maximum one is 100. The highest combination brings a big win, but the actual size of it depends on the cash investment.

Be sure to try the presented online casino game and express your opinion. If you want to play for fun, the credits are deducted from the additional balance (no need to spend real money).

RTP Rate and Paytable of Space Stacks

The manufacturer does not specify the hit frequency (volatility), so studying it yourself while running a demo version is better. The variance is considered to be average. Players will be interested in the theoretical return of the Space Stacks slot machine, as the RTP parameter depends on the choice of a particular prize block. There are five options:

• 88.47%;
• 90.22%;
• 94.29%;
• 95.25%;
• 96.23%.

The highest theoretical return the manufacturer promises when activating the bonus block. It is recommended to open the paytable beforehand to get acquainted with the main symbols. These chips are green, blue, and yellow. There are images of the crescent moon, triangle, and planets. When the max win is credited, the amount is multiplied by the coefficient of x5,000.

Bonus Options of Space Stacks Slot

Having tested the Space Stacks free slot, users can check out additional features at no cost. There are such bonuses as described below:

• Apex. The prize round resembles the main game, but the rules differ (the instant prize draw is provided). Six reels are shown on the screen. The initial values applied to them are 2, 3, 5, 7, 10, and 20. When the enhancement feature is triggered, the winnings are multiplied by a factor of x2 to x20 (one of the options is set entirely randomly). Once the column is filled, players receive a cash reward.
• Flip. A 6×6 grid is shown on the monitor, where users need to select three tiles (they are flipped upside down). In addition to multiplying by a factor of x1 to x1,000, a rocket symbol may appear with each subsequent roll the multiplier grows. Four possible multipliers exist – x2, x5, x10, and x100.
• Astro. The wheel of instant prizes starts after the corresponding symbols appear. You know which one you’ll get after the wheel stops. For example, it can be a cash gift from 2 to 1000 credits or multipliers from x2 to x100. The wheel is allowed to spin until it stops on the collection segment.
• Enhancement Feature. Six instant prizes are randomly distributed. Blocking tiles appear in each round; it ends after the reel is filled with similar images. If that happens, users get a win.

There are no bonus symbols like Wild and Scatter, so replacing the no-win images to get a paying combination is impossible. The Apex, Flip, and Astro icons trigger the bonus round. When two reels are filled, three different lives are activated, which are spent on the appearance of empty squares.

If you play the Space Stacks slot for free, you can estimate the chances of activating the bonus options. The percentage return does not increase thanks to them, but the game becomes more dynamic.

First 100 Spins in Demo Mode

I decided to start with the free version to get my first experience. When I launched the Space Stacks slot free play, I made 100 spins. While loading, I looked at the image of an unexplored planet in the space background shown on display. After a minute, it was possible to perform all the actions with the keys on the control panel. I decided to play without sound to perform the analysis without distraction.

I was provided 1,000 credits (the equivalent of the same amount in U.S. dollars), so I decided to bet 1 to simplify the calculations. Playing without downloading or registration, I first clicked the two on the blue background. After that, the playing field began filling, like real magic. The three reels were filled with images of a crescent moon on a blue background, a triangle on a purple one, and a planet on a green one. As a result, I got my first win of two USD.

I performed ten more spins without changing the bet. I watched as new combinations of green, pink, orange, and red images appeared. I decided to finish the game, keeping the same bet size. Bonus options were not activated, but the balance increased by several dollars. The conclusion is that the slot is suitable for real bets, and you can even do ten spins a day. It is enough to watch the movement of symbols on the reels to relax after a hard day’s work.

Brief Instructions on How to Start the Game

There are three extra keys in the upper right corner. Getting acquainted with them before launching free online Space Stacks is better for understanding the possibilities without additional costs. For example, clicking on the speaker’s image turns off the background sound. After clicking the button with three horizontal bars, a paytable with symbols, odds, and rules opens. Functions are duplicated by clicking “I” under the playing field.

The number of lines cannot be adjusted, so the game starts with a choice of rates. It is enough to click on a chip with a suitable value; the options include 0.01, 0.05, 0.10, 0.5, 1, 5, 10, and 100 USD. It remains to launch the reels with the essential manual or automatic spin. In the first case, a double arrow is used. In the second case, a single hand is used (it selects the optimal number of spins in advance). The result is known after stopping; it depends only on the work of the random number generator.

Players get winnings if the reel is filled with ten identical pictures. Several combinations can be formed in one spin, in which their values are added. Money (or renewable credits) are immediately transferred to the main account.
