If the ball draw matches at least one alien and no cows, then the aliens will abduct one of the cows. If no cows or aliens are marked, then the free spin shall act like an initial spin. The player will always get paid on his base game picks in the Alien Attack bonus, as usual. The game shall pick 20 numbers, as in conventional keno. The player choose the numbers previously marked as Bonus Spots. In the Alien Attack bonus, the Bonus Spots the player should pick three numbers to mark with cows and three to mark with aliens. If the player picks an Alien Attack, then he will play the Alien Attack bonus (a bonus within a bonus). In the Pick-a-Prize Bonus there is a grid of 19 icons, with the following distribution. If both Bonus Spots are hit, then the player will play the Pick-a-Prize Bonus. If less than two of the Bonus Spots are hit, then the game is scored as in conventional keno. The game will draw 20 random numbers, as in conventional keno. The player should choose two Bonus Spots from among the numbers he didn't already pick for the base game. The player may choose 2 to 10 spots for the base game. The base game is the same as conventional keno.The rules are rather involved, so bear with me. Sorry, a Gold membership is required for that one. I just came across the game Alien Attack Keno at.
