Keno Rules

Playing Keno online is much like picking numbers from a lottery ticket. You simply choose your numbers and watch the balls being drawn. The more of your chosen numbers that come up the more you win. It’s as simple as that. In fact, Keno is probably the most straightforward game you’ll find in an online casino.

How to Play Keno

To play a game of Keno online, follow these three steps:

  1. In regular Keno games you pick numbers between 1 and 80. You must choose at least three numbers and no more than ten.

  2. Choose how much money you want to play per bet. At online Keno sites the betting range is quite wide and you can choose to play for a few cents per game up to maybe $100.

  3. Choose how many rounds you want to play. You can play as many rounds as you want using the same numbers.

Once those steps are completed, click the play button and the game will begin.

At the end of each online Keno round, the results of the numbers will be shown and if you've won, money will be added to your account.

How to Win at Keno

Since Keno is a game of chance, there isn't much strategy you can use. Once the game has started, there’s nothing you can do to change the outcome of the game.

Of course, general strategy tips – such as finding the site with the best payouts, managing your bankroll wisely, and finding the best bonus before signing up – also applies to Keno.

Understand Keno Odds

Everyone knows the odds against winning the lottery are pretty long. Although Keno is a lottery-style game, the odds are a bit different.

Keno games allow you to choose how many numbers you want, and unlike lottery games, you can win by correctly guessing as few as one or two numbers.

The Numbers in Keno

Your odds in Keno are dependent on how many numbers you pick. The more numbers you pick, the more you have to catch to get paid off.

Getting a payout on all 15 or 20 numbers is very difficult relative to the odds, and the odds against correctly selecting all 15 are 20 are astronomical, even though the payout is huge.

The odds for catching 20 out of 20 are actually 1 in 3,535,316,142,212,180,000, which means that it’s almost impossible to do so.


Sample Keno Odds

In Keno, a popular strategy is to pick 8, 9 or 10 spots.

Compared to playing the full 20 numbers, this obviously increases the chance of getting all correct. But still the odds are quite long.

This is an example of a nine-spot game. Here you can compare the true odds (the actual chance that it will happen) with what you’re getting paid.

Analysis of Keno Odds

As you can see, the odds in keno are not particularly favorable to the player.

However, the possibility of winning thousands for a bet of only $2 is what draws people to the game-

If you are only for fun, and not with a winning expectation, this prospect of winning big for a minimal investment may make keno an enjoyable play.
