Bonus Spot Keno

On this page

Introduction

I first encountered Bonus Spot Keno, a unique version of Keno, at the Rampart casino in Las Vegas on January 15, 2016. This variant operates similarly to conventional keno , with the key difference being that players can earn a higher payout if their initial number selection matches one of the drawn balls.

Rules

  1. Players select between 2 to 10 numbers from 1 to 80.
  2. The initial number selected will be identified as the 'Bonus Spot', though players have the option to swap one of their other selections for the Bonus Spot simply by tapping the screen.
  3. The game will randomly select 20 numbers from the total pool of 1 to 80.
  4. The player's earnings will partially depend on how many of the selected numbers correspond with the 20 drawn by the game.
  5. Should the Bonus Spot correspond with one of the drawn numbers, payouts will be made according to the Bonus Spot pay table. If not, players will receive payouts based on the Standard pay table, which offers equal or lower payouts for winning combinations.
