Keno is a popular alternative game offered at numerous online casinos. Like a lottery game, it is one of the easiest games for beginner players to try.

The standard game offers numbers between one and 80. The idea is to choose 15 numbers. The game then randomly produces numbers to see how many you can match. Twenty numbers are drawn by the game to determine the outcome.

There are other variations that sometimes appear. 40-ball keno uses half as many balls, while the player only selects 10.

Another variation involves a bonus ball. If you correctly match it, a bonus prize is granted.

Odds vary for keno depending on how many numbers are matched in a game. While standard keno allows you to choose 15 numbers, you don’t need to choose that many. Doing so extends the odds. The more numbers you pick, the more balls you need to make a successful match for a prize.

That means better odds are available if you select between six and eight numbers. Odds can range from one in four when a single number is correctly chosen to one in 20 if you choose 10 numbers and need five to secure a prize.
