Aliens and spaceship greet you when you play Outta This World, with its space theme. There is a substitute symbol, an alien that covers all lines on the reel when he appears, and when used in a winning combination he doubles the prize value. Black holes are the scatter symbol, and scatter wins are a multiplier of the triggering bet.

The bonus game is triggered when a black holes shows on both reels two and four. Ten planets are then shown to the player, five of which hide free games and the rest hiding credit prizes. Player continues to select planets until two aliens are instead revealed, at which point the feature is over and any free games that were won, begin. All prizes during free games are doubled and the feature can be re-triggered during free games.
