Online Keno and All About It

Keno is a lottery-type game that originated in China during the Han dynasty around 205-187 BC. The ancient game’s origin lies with Cheung Leung, a government functionary who saw state-sanctioned gambling as a better method than additional taxation to raise funds for public works.

Modern lotteries and keno games were only legally allowed in China from 1847, but these games grew in popularity and were exported to Australia and the USA with Chinese migrants. Gamblers exchanged the Chinese characters for Arabic numerals to make the game more appealing to English-speaking players. Technology advances allowed software developers to offer keno online and on-demand to punters.

Online Keno Main Rules Explained

keno main rules

When you play online keno, you’ll find the same rules apply as in a live casino. The game is easy to understand and is based entirely on luck. You can have the convenience of playing a lottery on demand any time of the day.

You select the numbers you want to bet on, wait for the draw, and collect your winnings according to the paytable. Here’s a more detailed breakdown of the gameplay:

  • You have a grid with 80 numbers to choose from
  • Select the numbers you want to play on the grid
  • Most games will offer the choice to make a random selection on your behalf
  • Select the amount you want to bet on each combination
  • Select the number of games to play
  • Click on the Play button

You win if you’ve guessed some of the numbers correctly. The game paytable tells you what the game pays for winning number combinations. Winnings reflect on your balance immediately.

Understanding Types of Bets at Keno Game

When you play keno online, you’ll find that some games offer you different betting options. Although the names make them seem complicated, these variations on the way you place a stake are easy to understand. We’ve explained a few of the terms to help you know what to expect and the different bet types available in keno.

Online keno - straight ticket

Straight tickets

A straight or regular ticket is the most straightforward keno ticket there is. You select the numbers to bet on and add them to your card. The card is valid for one game, and your payout depends on how many numbers you guessed correctly.
online keno - way ticket

Way tickets

Way tickets allow you to choose and wager on number groupings, increasing your chances of a win. You can add several groups of five or ten numbers on your ticket and place your bet.
Online keno - king number ticket

King Number Tickets

You can designate a king number which will combine with other numbers on your card and as a stand-alone option, giving you an additional way to win. You can play a king number on any of the different ticket types.
Online keno - split ticket

Split tickets

A split ticket is a ticket with several number selections. You can play two games at once or split a card multiple times when you play keno game online. There’s no real advantage to a split ticket except convenience.

Combination Tickets

The combination ticket is the most versatile but also the most confusing of the keno tickets. A combination ticket allows you to combine way and straight bets on the same card and is most popular with online keno players.

Progressive Jackpot Games

The progressive jackpots in keno work the same way as slots progressive jackpots. The game has an initial seed amount, and a portion of each ticket bought contributes to the jackpot prize until somebody wins the grand prize. To claim 100% of the jackpot, you need to bet the maximum amount.

All About Odds, RTP & House Edge

Online keno odds and payouts

Keno has a very high house edge at 30%. A house edge of 30% means that 30% of all money contributed towards keno tickets is retained by the keno, and 70% is paid out as winnings. If you have 80 numbers to choose from, there is a 1 in 80 chance for each number to come up in each draw.

The chances of catching all three numbers on a three-spot ticket are 1%. The chances of having three numbers drawn off a four-spot ticket increase to 4%, and the odds of catching all 20 selected numbers on a full draw come to 1:3, 535, 316, 142, 212, 174, 320.

Most experienced keno players agree that you find the best odds on a ticket with between six and eight spots. You have a 0.01% certainty of catching all six numbers but a 13% chance of three numbers being drawn on a six-spot ticket. The best way to appreciate these odds is to try free keno before playing online keno for real money. We’ve provided a table below with payouts and odds of winning.

Keno Strategies That Might Help You

Keno strategiesAlthough keno is based purely on luck, it’s always helpful to have some strategies in place to decide on how you’ll bet. These strategies may even increase your winning chances. The first thing to do is look at the paytables on the game you’re playing and find the best RTP for the number of spots on the ticket. You typically find that choosing six or seven numbers gives you the highest RTP.

Online keno - return to player
Online Keno RTP (Return to Player) %
1 pick 2 picks 3 picks 4 picks 5 picks 6 picks 7 picks 8 picks 9 picks 10 picks
75% 98.10% 90.19% 89.02% 86.08% 93.79% 93.61% 92.94% 93.49% 90.82%
Online keno strategie - look for pattern

Strategy 1 – Looking for Patterns

  • Looking for patterns is also a popular strategy in other games like Lotto or bingo
  • Looking for patterns can be especially helpful in live games that use a ball machine
  • The theory is that some numbers come up more often than others
  • Make a list of the numbers that have come up over the longest possible period
  • Find the numbers that come up more often than others and which numbers the machine seldom catches or not at all
  • Only bet on the numbers that appear frequently

This strategy relies on the idea that some numbers come up more frequently than others. Most online casinos use a random number generator to determine the numbers. Each number should come up on average once every 80 times any number is drawn in an infinite number of draws.

Online keno strategie - play same number

Strategy 2 – Play the Same Numbers All the Time

  • Playing the same numbers all the time is also a popular strategy for Lotto games
  • Choose your favourite numbers and play them every time
  • You can even combine this strategy with looking for patterns to help choose the numbers to pick

The theory is that each number and number combination has the same chance of being drawn. By not changing numbers when you lose, you have a better chance that the numbers or number varieties will come up in the next game. The strategy means that you can be organized and disciplined after choosing the numbers and combinations you feel give you the best chance to win.

    The internet hosts a wide variety of casinos, each one with its features. Some offer incredible welcome bonuses and promise high rates of payouts (RTP). When looking for a casino to play Keno on, choose wisely.

  • Use Free Play Option to Test the Game

    Use Free Play Option to Test the Game

    The worst experience one can have in online Keno for money is placing your deposit and then realising later that you don’t like the game. Always utilise the online free Keno play options before you engage.

  • Select 4 to 8 numbers

    Select 4 to 8 numbers

    When you choose less than four numbers, the probability that you will win is very low. If you select more than eight numbers, you will have to get more than four digits in the draw before you see any profits. The idea is to increase your chances. If the winnings are small, it’s okay, just as long as they’re consistent.

  • Start Small

    Start Small

    The rule of thumb with playing any new game is to start small. Even if you have familiarised yourself with the Keno games free test versions, online gameplay is influenced by the money riding on the outcome.

  • Manage your bankroll

    Manage your bankroll

    Unlike popular belief, managing your bankroll is not only about knowing when to stop depositing money into a game but also knowing when to cash out. It’s not unheard of that a win translates into a loss.

  • Use Online Keno Bonuses

    Use Online Keno Bonuses

    Use the Keno bonuses awarded to you. The latter is there to bolster your chances of winning. Some allocated prizes have a use-by date. It would be a travesty to allow any bonus to expire without using it.
