In terms of gameplay, you have the Spin-Crease and the Free Spins bonus games, as well as Power-Ups, to add to the excitement. Ready to go through our Interstellar Attack review? Let’s do it!

How to Play Interstellar Attack Slot

If you’ve ever played a game by High 5 Games, you know that in the past, these games were Flash titles, but today, they are all HTML5 titles, playable across all casinos online on various devices. The moment you load the slot, you will see the Spin-Crease meter on the left of the grid, the grid in the center of the screen, and the Power-Up meter and the control buttons on the right.

First, you see the + button. Clicking or tapping on it, a pop-up appears giving you the Homepage, Speaker button where you can adjust the sounds of the game, and the “i” button, where the paytable is. Go to the paytable, and you’ll see that it is not your usual paytable, displaying the symbols and their payouts. Here, you learn more about the symbol upgrades, and the symbols necessary to accumulate to trigger the bonus features. These symbols are multicolored asteroids and aliens, which give you payouts of 0.5x to 100x the stake, depending on where they land. The telescope is the Scatter.

Next, you see the Play and Autoplay button, and below the reels, you see the Balance and Win displays, followed by the Bet Configuration field. You can place wagers from 0.20 to 40 credits at the best Pennsylvania and the best New Jersey slots sites.

Interstellar Attack Bonus Features and Free Spins

High 5 Games slots are all but simple to play, as you may have noticed, and Interstellar Attack is no exception. The game is packed with features and rules, so we’ll try to lead you through them all.

We said that the grid is 5x5, but there’s one extra special reel added as well. This is the last reel, where the spaceships appear. When a spaceship lands on the reel, it shoots for asteroids. These asteroids are accumulated in the Power-Up meter. When enough spaceships appear in the Spin-Crease meter, they upgrade the crystal symbols on the grid and give you a corresponding payout. When the Power-Up meter is full, you shoot the row bomb to explode every symbol on that row, you get a diverter or a 10x Multiplier.

In the meantime, the Scatter may appear floating above the five reels. If you manage to shoot it during the base game, you’ll trigger the Interstellar Attack bonus game. You will get 10 free spins no deposit, during which you won’t be collecting green crystals in the Spin-Crease meter, but Power-Up symbols will be placed at random on the reels. The Free Spins arrive in six levels, each arriving with its special payout.

Interstellar Attack Volatility, RTP & Max Win

Interstellar Attack is a medium volatile game, with a rather low default RTP of 94.00%, which can increase up to 97.20%, as stated by the developer.
