Fire Power Keno


On This Page

Introduction



Fire Power is a keno variant I noticed on multi-game machines made by U1. It is the same game as Power Keno, except the multiplier ball is the first drawn, not the last.

The same game is offered by Ace Gaming under the name Shockwave Keno.

Rules



  1. The player chooses 2 to 10 numbers from 1 to 80.
  2. The game will randomly choose 20 numbers from the same range of 1 to 80.
  3. The player is paid to number of his picks that match the numbers drawn by the game.
  4. If the first number drawn is a match then any win will be quadrupled.

The following pay table was observed at the Rampart casino on June 3, 2013, based on a $2 bet.
