How to Win at Keno: Odds, Pay Tables and Smart Choices That Actually Matter

There’s no system that guarantees a win at keno. Every draw is random, and the numbers you pick make no difference to your chances. What you can control is where you play, which pay table you choose, how many spots you pick and how much you stake. Those choices can change the house edge from more than 30% to under 10%, so they decide how long your money lasts and how often you leave with a profit.

This guide covers how to win keno games as often as the maths allows. You’ll find the real odds of hitting every number for 1 to 10 spots, a worked example that compares two pay tables, the myths worth ignoring and a short checklist to use before you play. If you’re still learning the basic rules, start with our beginner’s guide to playing keno and then come back here.

Keno draws 20 numbers from a pool of 80. You pick between 1 and 10 numbers, sometimes up to 15 or 20, and you’re paid according to how many of them come up. Those hits are called “catches”. The amount you get for each result is set by the game’s pay table, and the pay table always pays less than the true odds. That gap is the house edge.

That means nobody wins at keno over the long run. You can win individual sessions, and some players do land large prizes. Over many games, though, every player is expected to lose a percentage of the total amount they stake. To win at keno in any practical sense, you need to:

• Choose games that take the smallest possible share of each bet.
• Pick a spot count whose risk matches what you want, whether that’s frequent small wins or a rare large one.
• Control your stake and speed so a session lasts as long as you planned.
• Stop at sensible points, whether you’re ahead or behind.

The chance of catching all your numbers depends only on how many you pick. We calculated the probabilities below using the standard hypergeometric formula (20 balls drawn from 80). They’re the same at every fair keno game, whether it’s online or in a land-based venue.

Each extra spot makes the full catch roughly five or six times harder. The top prize grows to make up for that, but it usually doesn’t grow enough to give you better value. Many pay tables also pay for partial catches, such as 5 out of 8, and those smaller wins keep your balance going between bigger hits.

The biggest decision is the type of keno you play. Published surveys of land-based casinos show a large gap:

Online keno works like video keno. A random number generator (RNG) draws the numbers, and the RTP should be listed in the game’s help or info screen. Many online keno games use a single RTP for every spot count, while others set a different return for each one. Always check the figure for the version and spot count you actually plan to play.

Video and online keno have one catch: they’re fast. You can play hundreds of rounds an hour, compared with only a few at a live keno lounge. A lower house edge applied to many more games can still cost you more per hour. We cover this in the bankroll section below.

Only play at sites with a recognised gambling licence, because that’s your main assurance that the RNG and the published RTP have been tested.

Two 4-spot keno games can have the same odds and pay very different amounts. Here are the probabilities for a 4-spot ticket:

• Catch 4: 0.306%
• Catch 3: 4.32%
• Catch 2: 21.26%
• Catch 1 or 0: 74.1% (no payout on either table below)

Now compare two illustrative pay tables for a £1 bet. The amounts are total returns, including your stake.

Here’s how the numbers work out. Table A returns (0.2126 × £1) + (0.0432 × £4) + (0.00306 × £100) = about £0.69 per £1. Table B returns (0.2126 × £2) + (0.0432 × £6) + (0.00306 × £80) = about £0.93 per £1.

Table A has the bigger headline prize, but it’s the worse game by a long way. Over 200 £1 games, the expected loss is about £61.60 on Table A and £14.00 on Table B. Look past the top prize and check the RTP, or work it out from the pay table as shown above.

A quick test for 1-spot games: you catch your number 25% of the time, so a fair payout would be 4× your stake. A game paying 3.92× returns 98%, while one paying 3× returns only 75%.

The number of spots you pick doesn’t change the odds of any single ball. It does change your volatility, meaning how your results are spread out over time.

• 1–3 spots: you win often, but the prizes are small. Your balance moves slowly and steadily. This suits longer sessions on a small budget.
• 4–6 spots: a middle ground. Partial catches pay regularly, and a full catch gives a solid multiplier.
• 7–10 spots: you’ll have long losing runs, and most of the game’s value sits in rare large prizes. Plenty of sessions end without a meaningful win.

Pick the spot count with the best RTP on that particular game. If several have similar RTPs, choose the risk level that suits your budget. You shouldn’t need to top up your balance to keep chasing a 1-in-230,000 catch.

• Hot and cold numbers. Every draw is independent. A number that came up five times in a row is no more and no less likely to appear next time.
• Patterns on the board. Picking a row, a column, your birthday or a diagonal has no effect on the odds. All combinations of the same size are equally likely.
• Sticking with the same numbers. Keeping your numbers doesn’t make a hit “due”. Changing them doesn’t help either.
• Betting systems. Raising your stake after losses (Martingale-style progressions) doesn’t change the house edge. It only makes your losses bigger and faster. Our look at roulette betting systems tested in practice explains why, and the same maths applies to keno.
• Quick Pick vs your own picks. Random picks and chosen picks have exactly the same odds.

You can estimate your expected cost per hour with a simple formula: stake × games per hour × house edge.

For example, if you play 300 rounds an hour at £1 on a game with a 7% edge, you can expect to lose about £21 an hour on average. At 50p a round, that falls to about £10.50. Turning off auto-play or slowing down cuts the cost in the same way. Real results will swing well above or below these averages in any single session.

Practical rules that help:

• Set a session budget before you start and keep it separate from everyday money.
• Pick a stake that gives you at least 100–200 rounds from that budget.
• Decide on a win point, for example stopping if you double your budget, and a loss limit. Stick to both.
• Use auto-play sparingly. It makes playing faster and easier, which raises your hourly cost.

A casino bonus can give you extra play, but keno is often excluded from wagering or counts only partly towards it. A £10 bet might only clear £1 or £2 of the requirement, and some casinos don’t count keno at all. Bonus terms may also cap your stake or your winnings, and breaking those rules can void any wins.

Before you use bonus funds on keno, check the game weighting table and the maximum bet rule. Our plain-English guide to casino bonus terms explains what to look for.

Even the better online keno games usually have a higher house edge than the main table games. If what you mainly want is to make your money last, the games in our guide to casino games with the best odds are worth a look. Video poker with full-pay tables is one example.

Keno appeals to players for other reasons. It’s simple and relaxed, and a small stake gives you a shot at a big multiplier. If you like that lottery-style format, our guide on how to win at bingo uses a similar approach to choosing the best rooms.

• No strategy beats keno over time. The numbers you choose have no effect on the result.
• The choices that matter are the game type, the pay table, the spot count, your stake and your speed.
• Online and video keno usually return far more than live lounge keno. Always check the RTP.
• Compare pay tables by expected return, not by the size of the top prize.
• Fewer spots give steadier results, while more spots mean long losing runs between rare big wins.
• Set a budget and time limits, and never chase losses.

Keno is entertainment, not a way to make money. It’s for players aged 18 and over only. If gambling stops being fun, use the deposit limits, time-outs and self-exclusion tools at your casino, and get free, confidential support from a gambling support service.
