Keno is a simple numbers game that appears on many online casino sites. If you have not tried it before, the rules may look a little different from other games, but the basics are quick to grasp.
This blog post explains how keno works, where it came from, how odds and payouts are set, and what to expect when playing online. You will also find a clear comparison with bingo to help put the game in context.
By the end, you will know how online keno is structured and what affects potential returns. Read on to learn more.
Keno is a numbers draw game. Players choose from a pool, usually 1 to 80, and then a set of numbers is drawn at random. If you choose to play, the aim is to match as many of your selections as possible with the drawn numbers.
How much a player may win is set by the game’s paytable. The paytable shows what is paid for different match counts, based on how many numbers you chose in the first place. Every draw is independent, and each number in the pool has the same chance of being selected.
There is no technique that changes the outcome, since each round stands alone. Once you understand that core idea, the online version follows naturally.
Online keno presents a virtual ticket with numbers 1 to 80. Players typically pick between 1 and 20 numbers, often called spots. After confirming the choices, the game draws a fixed quantity of numbers at random, most commonly 20.
If you’re playing, your results are then checked against the draw. The more of your spots that match, the higher the payout according to that game’s paytable. Paytables vary across titles, and they change depending on how many spots you pick. For example, selecting 4 spots usually produces frequent small returns when 2 or 3 hit, while picking 10 spots can offer larger top payouts, but those higher matches are far less common.
Behind the scenes, certified Random Number Generators (RNGs) ensure each draw is independent. Previous results do not influence future ones, and no pattern can be relied upon to predict the next outcome. Many games also display Return to Player (RTP) information or a help page that summarises the paytable and rules, which might be something you want to review before you start.
Players can set the wager amount per ticket and choose whether to keep the same numbers or try fresh ones each round. If you’re considering playing, you might want to set a spending limit in advance and pace play to suit your budget.
Keno and bingo both revolve around random number draws, but they play quite differently. In keno, you decide which numbers to select before the draw. In bingo, you are given a card with pre-set numbers, and everyone listens for the same calls.
The win conditions are different, too. Bingo pays for patterns such as a line or a full house. Keno pays based on the number of your selections that match the draw, with no pattern requirements. Keno is also more individual in pace and structure, whereas bingo tends to be a shared session with fixed intervals and calls.
If you have played bingo before, you will recognise the entertainment of watching numbers land. Keno simply shifts that focus to your chosen spots and a paytable rather than grid patterns.

Keno traces back to ancient China, where early versions used characters rather than numbers. Over centuries, the game travelled and evolved, taking on local rules and formats as it went.
By the 19th century, Chinese immigrants had introduced versions of the game to other parts of the world. The modern numerical format became common in Western venues, eventually finding a home in both land-based and online casinos.
That journey explains why keno looks familiar yet distinct from other draw games. With the background in place, it helps to look at the odds and payouts that shape what you see on screen.
If you choose to play Keno, it’s beneficial to know how the odds and payouts work. Most versions of the game draw 20 numbers from a total of 80, and your chances vary depending on how many numbers, or “spots”, you select. Picking fewer spots tends to result in more frequent, smaller returns, while selecting more spots can offer larger potential payouts, although full matches become much less common.
Each game includes a paytable that shows what you’d receive for different match counts, based on the number of spots you’ve chosen. Even games that look similar can have quite different paytables; some are structured to offer steady, smaller prizes, while others are designed with the possibility of higher payouts from less frequent outcomes.
To put things into perspective, matching all 10 out of 10 chosen numbers is extremely unlikely. More typical outcomes include partial matches, such as 2 or 3 out of 5, which is why many games include smaller payouts or ticket credits for these lower matches. It’s also worth noting that each round is entirely random, and no pattern or approach can influence which numbers are drawn.
Yes, Keno is still played today, both in casinos and online. Its appeal often comes from the simple format, the flexibility in how quickly or slowly you can play, and the option to choose how many numbers (or “spots”) you want to pick. If you choose to explore online versions, you’ll find games available at any time, including on mobile, so you can dip in and out without needing to wait for scheduled draws.
There are also different versions you might come across. Some introduce bonus features, others change how many numbers are drawn, and a few are presented with live hosts to give the experience a more interactive feel. Even with these variations, the basic idea remains the same: choose your spots, watch the draw, and see how your picks match up against the paytable.
If you decide to give it a go, you might want to set a budget that works for you. Most platforms also offer tools like deposit or session limits, which can help you manage your play.
