INTRODUCTION
This video keno survey was done by testing randomly selected 25-cent video keno machines at each casino with a hotel component. Keno games included in the survey were standard keno, Cleopatra keno, Caveman Keno, Caveman Keno Plus, Extra Draw Keno, Power Keno, Top Bottom Keno, Triple Power, and Super Keno. In all cases except Top Bottom keno, the 10-spot pay tables were used to calculate the return. The average return shown is the average of all games found in that casino.
On a different site,the 4 spot was very good.5-7 is a better play.
Look for payout for 5 out of 5. 800 to 1 pay out is OK,838 is great.810+? Play it.
