Slot Machine With Cows And Aliens

Posted : admin On 17.02.2021

Invaders from the Planet Moolah slot machine from WMS has a totally unique theme. The premise of the game is that a herd of alien cows have jumped into spaceships – and come as a group to cause havoc on a farm. Flying saucer style ships, each captained by a cow, hover above the reels. Aliens™ is a video slot based on the famous science-fiction movie directed by James Cameron in 1986. It was created by the world’s leading provider of high-quality online casino games Net Entertainment in cooperation with 20th Century Fox. Among standout NetEnt games there are such as the Black Lagoon™, South Park™, Scarface™ and Frankenstein™ etc.

Introduction

Alien Attack Keno is a keno variant by Action Gaming. It features a bonus and another bonus within a bonus themed with a battle between cows and aliens. At the time of this writing, the game can be found at VideoPoker.com, where a Gold level membership is required to play that game. I imagine it will be seen on casino floors beginning in early 2021.

Rules

  1. The base game is the same as conventional keno, which I assume the reader is familiar with.
  2. The player may choose 3 to 10 spots for the base game.
  3. The player will choose two Bonus Spots from among the numbers he didn't already pick for the base game.
  4. The game will draw 20 random numbers, as in conventional keno.
  5. If less than two of the Bonus Spots are hit, then the game is scored as in conventional keno.
  6. If both Bonus Spots are hit, then the player will play the Pick-a-Prize Bonus.
  7. In the Pick-a-Prize Bonus there is a grid of 19 icons, with the following distribution. Prizes are relative to the bet amount.

  8. If the player picks an Alien Attack, then he will play the Alien Attack bonus (a bonus within a bonus).
  9. In the Alien Attack bonus, the Bonus Spots the player should pick three numbers to mark with cows and three to mark with aliens. The player choose the numbers previously marked as Bonus Spots.
  10. The game shall pick 20 numbers, as in conventional keno.
  11. The player will always get paid on his base game picks in the Alien Attack bonus, as usual.
  12. If no cows or aliens are marked, then the free spin shall act like an initial spin.
  13. If the ball draw matches at least one alien and no cows, then the aliens will abduct one of the cows.
  14. If the ball draw matches at least one cow and no aliens, then the player will win a multiplier to be applied to the base game win. This multiplier is 2x for one cow hit, 3x for two cows hit, and 5x for three cows hit.
  15. If the ball draw matches at least one cow and one alien, then what I will call a 'milk battle' will ensue. This is displayed as the cows hurling milk and cheese at the aliens. The number of shots fired by the cows will equal the product of the number of cows and number of aliens spots marked in the ball draw. Each shot fired shall award a random prize. The prize weightings depend on the number of cows remaining, as follows.

    Total2020

    In addition, if the player has one or two cows, then with each shot fired there is a 60% chance at a cow rescue. The probability of a cow rescue is 12/13 if the Milk Battle prize was 1, otherwise it is 0. At most, one cow may be rescued per bonus game. Although the game presentation may show otherwise, the cow is not rescued until the end of the bonus game. In other words, the number of cows is taken as the total at the beginning of the bonus game.

  16. The bonus shall keep playing until the player has no cows left.

The overall game return, for the 2-8-60-230-1500 pick-8 pay table can be broken down as follows:

  • Base game = 0.494839
  • Pick a Prize bonus = 0.145576
  • Alien Attack bonus = 0.253692
  • Total = 0.894107

It should be noted that the makers of this game claim a return for the same pay table of 89.467%. The reason for the 0.056% difference I attribute to random variance in the simulation. Winamax free rolling.
