The Extra Draw That Changes the Payout
Keno is one of the oldest lottery-style games in a casino, and most players already understand the core loop: pick a set of numbers, watch the draw, and get paid based on how many of your picks match. Keno Plus 3 keeps that loop intact but adds a second stage after the main draw. One additional number is drawn from the remaining pool, and that number becomes a multiplier applied to any winning combination from the base draw.
The name tells you the structure. The "Plus 3" refers to the bonus draw that happens after the standard 20-number keno draw. If your ticket has already produced a winner, the bonus number determines whether that win gets multiplied, and by how much. The multiplier value is typically tied to the bonus number itself, so different bonus numbers can produce different multiplier levels.
This is not a separate game running alongside keno. It is a single ticket with two draw stages. You buy the ticket, select your numbers, and the same ticket participates in both the base draw and the bonus draw. The bonus draw only matters if the base draw has already produced a paying combination.
How the Base Game Works First
Before the multiplier means anything, you need a winning keno ticket. Standard keno asks you to pick between a minimum and maximum number of spots, usually somewhere between 1 and 10 or 1 and 15 depending on the operator. The game then draws 20 numbers from a pool of 80. Your payout is determined by how many of your selected spots appear in those 20 drawn numbers.
The paytable is the document that matters here. It lists every possible combination of spots selected and matches hit, with a payout attached to each. A ticket with fewer spots selected pays more per match because the probability of hitting all of them is lower. A ticket with more spots selected has a higher chance of hitting something, but the payouts for partial matches are smaller. The paytable for Keno Plus 3 is usually adjusted downward from standard keno on the base game, because the bonus draw adds expected value that has to come from somewhere.
Always read the paytable before you buy the ticket. The same number of matches can pay differently depending on how many spots you selected, and Keno Plus 3 paytables are not identical across operators. The game information panel or help screen inside the game client is where the operator publishes the exact figures.
What the Bonus Draw Does
After the main 20-number draw settles, the game draws one more number. That number is the multiplier trigger. The relationship between the bonus number and the multiplier is fixed in the game's rules, and it is usually displayed on the same screen as the paytable.
Some versions of Keno Plus 3 assign a single multiplier to every winning ticket when the bonus draw happens. Other versions use a tiered structure where certain bonus numbers produce higher multipliers than others. The key distinction is whether the multiplier applies to all winning combinations on your ticket or only to specific match levels. A game might multiply a 5-of-5 hit but leave a 2-of-5 hit at the base payout. The rules screen is the only place that tells you which structure applies.
What the bonus draw does not do is create a win that was not already there. If your base ticket has zero matches, the bonus number does not turn it into a winner. The multiplier only applies to combinations that the base draw has already paid. This is the most common misunderstanding about the variant, and it changes the math significantly. The bonus draw is a payout enhancer, not a second chance to win.
Where the Multiplier's Expected Value Comes From
Keno already carries one of the higher house edges among casino games, and the variant does not change the fundamental structure of the game. The operator is not giving away extra money. When a multiplier is added to a keno ticket, the base paytable is adjusted to keep the overall return where the operator wants it. The multiplier redistributes some of the payout from the base game into the bonus stage.
This matters for how you read the paytable. A Keno Plus 3 ticket with a 4-spot selection might pay slightly less for a 3-of-4 match than the same ticket on a standard keno game. The difference is the cost of the multiplier feature. Over a very large number of tickets, the expected return includes both the reduced base payouts and the occasional multiplied win. The two together produce the game's overall RTP, which is published in the game's information panel.
Volatility also shifts. Because the multiplier concentrates additional payout into the tickets that already won, the distribution of outcomes becomes wider. Winning tickets can pay significantly more when the bonus draw lands favourably, but the base game pays slightly less on average. The result is a game with more variance than standard keno at the same spot count.
Comparing the Variant to Standard Keno
| Feature | Standard Keno | Keno Plus 3 |
|---|---|---|
| Draw stages | One draw of 20 numbers | Main draw plus one bonus number |
| Payout structure | Fixed paytable based on matches | Base paytable plus multiplier on winning tickets |
| Multiplier trigger | None | Bonus number drawn after the main draw |
| Effect on non-winning tickets | No payout | No payout; multiplier cannot create a win |
| Base paytable | Standard rates for the spot count | Often adjusted downward to fund the multiplier |
| Volatility | Moderate to high depending on spots | Higher, with more payout concentrated in winning tickets |
Reading the Rules Screen Before You Play
Keno Plus 3 is not standardised across the industry. Different game developers and different operators run different versions of the bonus draw, and the only reliable source for the version in front of you is the rules screen inside the game client. Three things on that screen matter more than anything else.
First, find the multiplier table. It tells you which bonus numbers produce which multipliers, and whether the multiplier is flat or tiered. Second, find the base paytable and compare it to the standard keno paytable for the same spot count if the operator offers both. The difference shows you what the multiplier feature costs. Third, check whether the multiplier applies to all match levels or only to certain ones. A multiplier that only applies to 4-of-4 and 5-of-5 hits is a very different feature from one that applies to every winning combination.
The rules screen also carries the game's RTP figure, which is the theoretical return over a very large number of tickets. It is a long-run statistical average, not a prediction of what any single session will return. Use it to compare Keno Plus 3 against other keno variants, not to forecast a result.
What Stays the Same Across Every Keno Variant
The core mechanic of keno does not change when a multiplier is added. You are still selecting numbers from a fixed pool, still hoping to match a subset of a random draw, and still facing a house edge built into the paytable. The draw itself is generated by a random number generator, and in a regulated environment that RNG is tested by independent laboratories to confirm that outcomes are not predictable or manipulated.
What changes in Keno Plus 3 is the shape of the payout distribution. The multiplier moves some of the return from frequent small wins into less frequent larger wins. That is a volatility change, not a return change. The game's RTP is what it is, and the multiplier does not make the game more generous in the long run. It makes the winning tickets more exciting when they happen, and it makes the losing tickets slightly more expensive in expected value terms.
That is the honest way to think about the variant. It is a pacing change. If you enjoy keno and want the occasional bigger payout on a winning ticket, the multiplier structure delivers that. If you prefer the flatter, more predictable payout curve of standard keno, the base game is the better fit. Neither choice changes the fundamental arithmetic of the game.
FAQ
Does the Keno Plus 3 bonus number count as one of my selected numbers?
No. The bonus number is drawn separately after the main draw and is used only to determine the multiplier. It does not add to your match count, and it cannot turn a non-winning ticket into a winning one. Your matches are determined entirely by the 20 numbers in the main draw.
Is Keno Plus 3 a better bet than regular keno?
Not in terms of expected return. The multiplier feature is funded by adjustments to the base paytable, so the long-run return is set by the operator and published in the game's RTP figure. The variant offers a different volatility profile, with bigger payouts on winning tickets and slightly lower base payouts. Which one is "better" depends on what kind of payout pattern you prefer, not on one having a mathematical advantage over the other.
Can I see the multiplier table before I buy a ticket?
Yes. The multiplier table is part of the game rules and is displayed on the same screen as the paytable, usually accessible through a help or information button inside the game client. Read it before you commit to a ticket, because the relationship between the bonus number and the multiplier varies between game versions and operators.
