When starting to play you make your picks which are choosing the number of spots that you are going to mark on your keno card. With the wager you have placed it doesn’t affect the amount of spots that you pick, only the resulting odds.
Once you have made your picks, then 20 randomly picked numbers are chosen at random and show up on your computer screen. Dependent upon how many spots you had placed and how many of those numbers matched affects your odds on winning.
The keno rules are the same for both online and land based casinos when it comes to the payout schedules that are used to make payouts.
You will find if you had picked only five numbers and three were chosen that the payouts would be better then if you had picked 10 and only three had been drawn. Definitely the more spots that you pick the more stretched out will be the payout scale.
If you understand the keno rules the next thing you should be concerned with are the Keno strategies of which I feel the number one strategy is managing the initial bankroll that you started out with. With keno you will realize that winning is usually in favor of the online casino and that thinking that there is a specific strategy to use will not help you in the long run.
Actually the best strategy you can make is to bet what you can afford and if you loose your bankroll it is time to quit. Remember there is always another day that you can play at your favorite online casino.
