Set on a 5×4 grid in the middle of the galaxy, the game diverges from traditional slot games with its spatial theme and interactive features. Players start their adventure by setting a bet between 20 and 4,000 dollars, aiming to shoot and destroy monsters while collecting power-ups and advancing through levels. The game incorporates a Spin-crease meter and a Power-Up meter, enriching the gameplay with strategic elements not commonly found in slots.

Bonus Features

Interstellar Attack is packed with innovative bonus features that elevate the gaming experience. Here’s a breakdown of the key bonus features:

  • Spin-Crease Feature: Players increase their Spin-crease meter by destroying asteroids and monsters, unlocking new symbols and power-ups.
  • Power-Up Meter: Collecting red fuel components from destroyed asteroids fills the Power-Up meter, granting access to two power-up symbols that can significantly boost winnings.
  • Free Games Bonus: Triggered by shooting a grey telescope, this feature awards ten free spins without the collection of fuel components, but includes random power-up symbols on the reels.
  • Spaceship Upgrades: Increasing the Spin-crease meter also upgrades the player’s spaceship, enhancing their ability to clear reels and win more effectively.


The Interstellar Attack slot features a variety of symbols that pay homage to classic video game aesthetics, including different colored monsters and space-themed objects. Here’s a closer look at the symbols and their significance:

  • Monsters: Symbols include Orange, Purple, Green, and Pink monsters, each with different values.
  • Asteroids and Spaceships: These symbols contribute to the game’s space battle theme, interacting with the gameplay mechanics like the Power-Up meter.
