Keno Has No Single Winning Number
A keno ticket does not work like a lottery draw where one fixed set of numbers wins. You choose how many numbers to play, and the paytable that applies to your ticket tells you what happens at each level of hits. The question "how many numbers do you have to win" therefore has no single answer: it changes with how many spots you mark, which paytable the game uses, and what you count as a win.
The game itself is simple to describe. A field of numbers, usually 1 through 80, is displayed. You mark a set of them, commonly between 1 and 10 or 1 and 20 depending on the game. The draw then selects 20 numbers from the same field. Your result is how many of the drawn numbers match the ones you marked. Those matches are called hits, or catches. The paytable converts a given number of hits on a given number of spots into a payout.
Because you control the number of spots, the meaningful question is not "how many numbers win" but "how many hits on my chosen number of spots produce a payout, and how large is that payout." A player who marks one number needs that single number to appear. A player who marks ten numbers may receive something for four, five, six or more hits, depending on the table. The same number of hits can pay differently on different spot counts. Five hits on a six-spot ticket is usually a strong result; five hits on a ten-spot ticket is often a modest one or no payout at all.
How a Keno Paytable Works
Every keno game publishes a paytable. It is a grid that lists, for each number of spots you can play, what each possible number of hits pays. The paytable is the only document that answers the question for a specific game. Reading one is straightforward once you know what the columns mean.
The rows are spot counts, the columns are hit counts, and the cells are payout multiples of your stake. A cell might show 0, meaning that combination pays nothing, or a number such as 3, meaning the payout is three times the amount wagered. Some paytables show a range of payouts for the same hit count because the game operator may offer several tables, and the machine or app will display the active one.
No universal standard exists. Two keno games in the same venue can use different paytables, and the same game can offer a choice of tables with different volatility. A table that pays something for fewer hits will generally pay less at the top end. A table that pays nothing until a high hit count will generally offer a larger top payout. The trade-off is built into the arithmetic of the game.
When you open a keno game, the paytable is usually one tap or click away, often behind a button labelled "paytable", "pays", "info" or "help". The game rules screen also states how many numbers are drawn, the maximum spots you may mark, and whether any side bet or progressive jackpot is attached. Read that screen before you mark a ticket, because the same spot count can sit on materially different tables.
What Counts as a Win Depends on the Spot Count
The relationship between spots, hits and payouts is easier to see side by side. The table below shows the shape of a typical paytable, with example payout multiples only. Real games vary, so treat the numbers as illustrations of structure, not as rates that apply anywhere.
| Spots marked | Hits that usually pay | What the payout tends to look like | What to check on the real table |
|---|---|---|---|
| 1 | 1 | A small fixed multiple of the stake | Whether a single hit pays at all |
| 3 | 2 or 3 | 2 hits often return the stake or a little more; 3 hits pay several times the stake | Whether 2 hits pay anything |
| 6 | 3 to 6 | 3 hits may pay a token amount; 4 to 6 pay increasing multiples | The exact multiple at each hit level |
| 10 | 5 to 10 | Lower hit counts may pay nothing; the top end pays a large multiple | Where the first paying level sits |
The pattern is consistent across keno variants: the more numbers you mark, the higher the hit count you generally need before a payout appears, and the larger the top payout can be. Marking fewer numbers gives you a better chance of hitting a high proportion of your spots, but the absolute payout is smaller. Marking more numbers opens the possibility of a large multiple, but most draws will leave you below the first paying level.
This is why the question "how many numbers do you have to win" cannot be answered with a single figure. On a one-spot ticket, one number wins. On a ten-spot ticket, one number is almost always worthless. The same draw can produce a win on one ticket and a loss on another, because the tickets carry different spot counts and therefore different thresholds.
The House Edge in Keno Is Built Into the Paytable
Keno is a game of pure chance. No selection method changes the probability that a given number will be drawn. The operator's mathematical advantage comes from the paytable: the payouts are set so that, over a very large number of tickets, the total returned to players is less than the total wagered. That gap is the house edge, and it is the complement of the game's return to player, or RTP. House edge and RTP sum to 100% for the same game under the same paytable.
Keno paytables generally carry a higher house edge than many other casino games, but the exact figure varies by table and by spot count. Some spot counts on the same paytable are better for the player than others, meaning the expected rate of loss is lower. The only way to know which spot count that is, for the table in front of you, is to compare the payout multiples against the probabilities of each hit count. The game itself will not tell you this; it is arithmetic you can do with the paytable and a probability chart.
What the paytable does tell you directly is the payout for each outcome. What it does not tell you is the probability of each outcome. A large top payout on a ten-spot ticket is rare, and the paytable is constructed around that rarity. A small payout on a one-spot ticket is common. Neither is a better or worse choice in any absolute sense; they are different distributions of the same underlying edge.
Variations That Change the Answer
Several keno variants alter the relationship between hits and payouts enough that you should check the rules before assuming a familiar table applies. The most common variations are worth knowing by name.
- Way tickets: You split one ticket into multiple groups of spots, called ways. Each way is judged separately against its own paytable, and the ticket pays the sum of the winning ways. A way ticket can therefore pay on a partial match even when no single group hits its top level.
- Combination tickets: Similar to way tickets, but the groups overlap or combine into larger groups. The same marked numbers can form several spot counts at once, each with its own payout line.
- Progressive keno: A jackpot grows from a share of qualifying wagers and resets after a win. The progressive is usually attached to a specific spot count, often the maximum, and may require a side bet or a maximum-stake ticket to qualify.
- Video keno versus live keno: Video keno draws immediately after each ticket and usually offers faster play and a wider range of spot counts. Live keno draws on a fixed schedule, and the paytable may differ from the video version in the same venue.
Each of these variations changes what you need to hit, or what a given hit count pays. The paytable remains the controlling document. In progressive keno, the base paytable applies to all non-jackpot outcomes, while the jackpot line applies only to the qualifying outcome, usually all spots hit.
How to Read the Rules Screen Before You Play
When you sit down at a keno game, whether on a screen or at a live lounge, the answer to "how many numbers do I have to win" is on the rules screen and the paytable. Before you mark a ticket, check four things.
First, confirm how many numbers the draw selects. Most keno games draw 20 from 80, but some variants draw fewer or more, and that changes every probability on the ticket. Second, find the range of spots you may mark. Third, open the paytable for the spot count you intend to play and read the payout for each hit level, including the zero-payout levels. Fourth, check whether a progressive jackpot or side bet applies, and whether it requires a specific stake or spot count to qualify.
If the game offers more than one paytable, the active one is usually shown on the same screen where you choose your stake. Switching tables changes the payout multiples, and therefore changes the house edge on the same ticket. The difference between two tables can be larger than the difference between two spot counts, so the table choice matters as much as the spot choice.
No amount of number selection changes the draw. The numbers you mark are a preference, not a strategy. What you control is the spot count, the paytable you play, the stake per ticket, and how many tickets you buy. Those choices determine the rate at which you lose, on average, and the shape of the outcomes you will see along the way.
FAQ
Does hitting zero numbers ever pay in keno?
Some paytables include a payout for zero hits on certain spot counts, but it is not standard. Check the paytable for the spot count you are playing; if a zero-hit payout exists, it will be listed as a payout line alongside the other hit counts.
Is it better to pick more numbers or fewer numbers in keno?
Neither is better in a way that changes the underlying edge. Fewer spots produce more frequent small payouts, while more spots produce rarer large payouts. The house edge varies by spot count on the same paytable, so the only way to compare is to calculate the expected return for each spot count from the payout multiples and hit probabilities.
Do keno machines show the paytable before you bet?
Yes. Video keno machines and online keno games are required to make the paytable available before play, usually through a help, info or pays button. Live keno lounges print the paytable on the ticket or display it at the writing station. If you cannot find it, ask the staff or check the game's rules screen before marking a ticket.
