How to Play Keno Online

A Draw, Not a Game of Play

Keno asks the player to mark numbers from a field of 80. Twenty numbers are then drawn at random, and the prize depends on how many of the marked numbers appear among them. There is nothing to decide after the ticket is submitted and nothing a player does affects the draw. The Maryland Lottery, which runs keno as a state game, describes the structure in its own words: a field of numbers from one to 80, up to ten chosen, a computer continuously generating random sets of twenty numbers, with a set locked in every three and a half minutes.

The Pay Table Is the Entire Difference Between Two Keno Games

Keno's rules barely vary. Its returns vary enormously, and the reason is that nothing fixes a keno pay table the way a roulette wheel fixes roulette's. Light & Wonder's iGaming catalogue makes the point with the games on it: 87.5% for Neon Keno, 87.55% for one title called Keno, 92.84% for Keno Pop, 94.45% for a second Keno, 95% for Keno 80 and 96.2% for a third Keno. Two further titles carry their own studio names on the same catalogue — Lightning Box Keno, published at 94% and 96% as two configurations of a single game, and Pixiu Gaming's Keno Multiplay at 93.55%. Two more are themed and published lower still: World Cup Keno at 80% and Keno Kick Off at 84.9%. More than sixteen percentage points separate the highest figure on that catalogue from the lowest. The six titles named Keno play the same way as each other, so between those the pay table is the whole of the difference; Lightning Box Keno adds a respin feature of its own and Keno Multiplay plays several tickets at once, so for those two the pay table is the main difference rather than the only one.

How Spots Work

A keno pay table is a grid. Each quantity of numbers marked has its own column, and within a column the prize rises with the number of hits. Marking eight numbers rather than three does not improve the chance of any individual number being drawn; it settles the ticket against a different column with different hit requirements and usually rarer, larger prizes. Some pay tables also pay for matching none of the marked numbers. Choosing a spot count is choosing the shape of the outcome, not the odds of the draw.

What Is Published, and What Is Not

The published figures below belong to named games rather than to keno, because no acceptable source publishes one and there is no such thing to publish. A reader who wants to know what a particular keno game returns has to read that game's own information screen; a reader comparing two of them is comparing pay tables. Beyond the pay table most keno games work the same way, and where one does not it says so: the variants below each name what they add.

Lottery Keno Is a Different Product

Several governments run keno themselves and publish their own prize structures for it. Those games share the 80-number field and the 20-number draw with casino keno and nothing else: not the stakes, not the pay tables, not the returns. Figures from a state lottery's keno do not describe a casino keno game, and the reverse is equally true.

The Object of the Game

Keno is a numbers draw. The player marks a selection from a field of 80 numbers, then 20 numbers are drawn at random, and the prize depends on how many of the marked numbers appear among the drawn ones. There is no hand to play, no dealer to beat and nothing to decide once the ticket is submitted.

How a Game Runs

1. The player chooses how many numbers to mark — commonly anywhere from one to ten — and which numbers those are.
2. A stake is set for the game.
3. Twenty numbers are drawn at random from the 80.
4. The prize is read off the pay table for the number of spots marked and the number of hits achieved.

The Maryland Lottery, which runs a version of keno as a state game, describes exactly this structure: a field of numbers from one to 80, up to ten numbers chosen, and a computer continuously generating random sets of 20 numbers, with a drawing locked in every three and a half minutes. Casino and online keno use the same 80-number field and the same 20-number draw. What they do not share is the pay table.

Spots, Hits and Why Both Matter

A keno pay table is a grid rather than a list. Each quantity of spots marked has its own column, and within that column the prize rises with the number of hits. Marking more numbers does not make a hit more likely on any individual number — it changes which column of the grid the ticket is paid from. In some versions, matching none of the marked numbers also pays.

The Pay Table Is the Game

Keno has no standard pay table, and this is the single most important fact about it. Light & Wonder's iGaming catalogue illustrates the spread: it publishes 87.5% return for Neon Keno, 87.55% for one game called Keno, 92.84% for Keno Pop, 94.45% for another Keno, 95% for Keno 80 and 96.2% for a third Keno. Alongside them, Lightning Box Keno is published at 94% and 96% — two separate configurations of the same game — and Pixiu Gaming's Keno Multiplay at 93.55%, with World Cup Keno at 80% and Keno Kick Off at 84.9% lower again. That is a difference of more than sixteen percentage points on one catalogue. Among the titles simply called Keno it comes entirely from the pay table; Lightning Box Keno and Keno Multiplay each add a feature of their own on top of theirs.

The practical consequence is that a keno player comparing two games is comparing their pay tables, and that a figure quoted for 'keno' describes nothing in particular. Where a game states a return figure in its own information screen, that figure is for that pay table and that configuration.

Casino Keno and Lottery Keno Are Not the Same Product

Several governments run keno as a lottery game, and those versions publish their own prize structures. They share the 80-number field and the 20-number draw with casino keno and they do not share its pay tables, its stakes or its returns. A figure read off one does not apply to the other.

Nothing in the Game Can Be Played

Keno offers no decision that affects the draw. Twenty numbers are generated at random from 80, independently of what is on any ticket. Marking the numbers that came up last time, or the ones that did not, changes nothing — each draw is generated on its own.

The One Choice That Does Change Something

How many numbers to mark decides which column of the pay table the ticket is settled against. A two-spot ticket and an eight-spot ticket are playing different prize structures in the same game: different hit requirements, different prizes, different distributions of outcome. More spots does not mean better odds on each number — it means a different set of possible results, usually with rarer and larger prizes. Picking a spot count is choosing a shape of outcome, not improving the chance of a win.

Compare the Pay Tables, Because Nothing Else Differs

Keno is the clearest case of a game whose cost is entirely a property of its pay table. One catalogue's published figures for its online keno games run from 80% to 96.2%, and one title on it ships in two configurations published at 94% and 96%. Those titles share the 80-number field and the 20-number draw; what differs between them is the pay table, and in two cases a feature the supplier names on top of it. A player choosing between two keno titles is mostly choosing between two pay tables, and a keno game's pay table is published on its own information screen.

What No System Does

Keno's draw is random and independent, so no pattern of numbers, no staking progression and no choice of machine improves the expected result. Every keno title whose return figure is published above keeps a share of the amount staked — the best of them nearly 4% and the worst a fifth of it — and none of them has a positive expectation for the player.
