How to Play Interstellar Attack

The grid layout of Interstellar Attack seems a bit complicated yet remains pretty easy to play. Kickstart your interstellar adventure using the "+" and "-" buttons to place bets.

There are four distinct types of spaceships appearing on reel 1, firing vertically on the symbols above. Payouts differ according to the number of symbols lying in front of the spaceship and the type of spaceship you are using. At times, multiple spaceships can land on reel 1, increasing your chances of bigger payouts. Symbols shot down either contribute to the Spin-crease metre on the grid's left or the Power-up metre on the right side.

Striking down green crystals gives the corresponding payouts. You can also win by filling the Spin-crease or Power-up metre. High 5 Games has specified Interstellar Attack's RTP starts at 90% but can increase up to 97.2% as symbols get upgraded using the Spin-crease feature. Although the maximum win amount is not mentioned, the sixth bonus level of Interstellar Attack offers a staggering 25000x the total bet amount.

Interstellar Attack Bonus Features

Interstellar Attack comes with its own set of bonus features and rules. The slot's primary highlight is the free game feature but keep an eye on Spin-crease and Power-up metre to enhance your winning chances.

• Spin-crease Metre: The Spin-crease metre is constituted of spaceships. Green crystals keep increasing the tally of this metre. All the crystal symbols are upgraded once there are enough spaceships in the Spin-crease metre. A spaceship is upgraded if the metre is full, or a new one is added to reel 1.
• Power-up Metre: As asteroids are shot down by your spaceships, the red crystals get accumulated in the Power-up feature. Once the Power-up meter is full, new symbols are added to the reels, and you also get a row bomb shooting down all symbols in a particular row.
• Free Games: Shooting down the alien ship hovering above the top reel triggers the free games feature. Initially, 10 free spins are awarded where you can move up to six levels. The first level starts with 10x the total bet amount, but as you move up, the multiplier value increases, giving you a whopping 25000x the total bet amount on level 6. Spin-crease is not active during the free games feature.

Free Games also offer random multipliers from 2x to 10x along with special feature symbols providing an additional free game.
