Due to the random nature of Keno, many people simply play the numbers that they feel some sort of connection with. Others tend to play all 8 corners of the Keno slip, or find some other pattern that they feel is good.
One of the things that most people agree on, is the fact that you should learn about bankroll management. This can be considered the most important strategy concept in Keno, as you will be able to follow a simple set of rules and know how to play and when to take profits and leave for the day.
First you will need to set your daily budget. To do this, determine the amount of money you are willing to spend on Keno play, and make sure it is an amount you can afford to lose without impacting your daily expenses or financial situation.
