One can name Keno a game of chance. There is almost no strategy which can help the player to win. The drawn numbers have no relation to those drawn previously as numbers are chosen randomly. All numbers have the same opportunity of being drawn.
Play the numbers that you haven't seen come up in recent games. Theoretically the long-term results for each number will be made even out by the coming up of these numbers. The "random" nature of the game helps to prevents this from being a certainty.
However many keno players will bet on the numbers, which have come up instead of betting on the numbers that haven't come up. And still there are interesting trends and patterns which can be very profitable.
Pick successive numbers. The players consider pairs such as 12 and 13 or perhaps 43 and 44 to be successive. This is a very popular belief among many Keno players.
The same set of numbers should be used consecutively. The simplest and the most common strategy is to play the same selection of numbers for a few rounds.
These strategies are a bit of fun and they won't harm your chances of winning anyway.
