As far as pure strategy goes, keno isn't the same as games like blackjack or poker. You can't bluff, and in reality the only real choices that you get are which numbers that you choose and how much you want to bet on that game. This may seem like there's not much that you can do to improve your odds, but that's far from the truth.
These strategies won't work for every player every time,but they area great guide for where to start with playing keno. The best thing to do is to try some, and see what works for you at the time. Some may be better then others for you and your games keep on at it!
Chasing The Pack involves playing the numbers that have come up recently. When you see numbers being drawn over and over again, you should use those numbers as they are looking to be great at that time
Chasing The Strays involves taking the numbers that haven't come up. This works because overall, each number will be drawn the same number of times, so the less often they show up now, the more often they should show up later on.
Play It Again involves playing the same numbers that you played on the last loosing game. This works on the same idea that Chasing The Strays does with numbers being more likely to be drawn if they haven't been drawn yet.
How often do you look at the keno board and see numbers together? It's a very regular thing in keno, so taking numbers that are side-by-side on the forms, and consecutive numbers can give you a good advantage.
