Power Keno

Introduction

The rules in Power Keno are the same as regular keno, except if the player catches the 20th ball drawn, then any winnings are quadrupled. There is also a similar game called Fire Power, which is the same except in that game wins are quadrupled if the first ball is a catch, not the last one.

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.
