The side bet that changes the paytable
Keno Super Bonus is not a separate game. It is a side bet you add to a standard keno round, and it changes what certain winning combinations pay. When you place the Super Bonus wager, the game uses a different paytable for that round, usually one that multiplies the payout on specific hit counts or on a particular number that the game draws as a bonus number.
The core keno mechanics stay the same: you pick a set of numbers from a larger board, the game draws a fixed quantity of numbers, and you are paid according to how many of your picks match the draw. The Super Bonus bet sits alongside that base wager. If you do not place it, the standard paytable applies. If you do place it, the machine or game client checks the bonus condition after the draw and pays the bonus amount if the condition is met.
What varies between implementations is the trigger. On some versions the Super Bonus activates when a designated bonus number is among the drawn numbers. On others it activates when you hit a certain count of your chosen spots, such as a high-count match, and then applies a multiplier to that win. The multiplier itself is not a universal figure. It is printed on the paytable for the specific game version you are playing, and it can differ between a video keno machine, an online keno game, and a live keno draw.
How a round plays with the bonus active
A Super Bonus round follows the same sequence as any keno round, with one extra decision before the draw. You choose how many numbers to play, pick those numbers, decide your base stake, and then decide whether to add the Super Bonus side bet. The side bet usually has its own cost, often a fixed amount or a fixed multiple of the base stake, and it is collected whether or not the bonus condition hits.
After the draw, the game settles the base wager first using the standard paytable. Then it checks the bonus condition. If the condition is met, the game adds the bonus payout on top of the base win. If the condition is not met, the side bet is lost and the base wager settles as it normally would. The two settlements are independent in the sense that a losing base round can still produce a bonus payout on some versions, while on other versions the bonus only pays when the base round has already produced a win of a certain size.
Because the bonus is a side bet, it carries its own expected return. The house edge on the Super Bonus wager is not necessarily the same as the house edge on the base keno wager. A paytable that looks generous on the bonus line may be balanced by a lower return on the base paytable, or by a bonus trigger that is rare enough that the side bet loses far more often than it wins.
What the paytable tells you
The single most useful document for any Super Bonus game is the paytable. It lists every possible hit count, the base payout for that count, and the bonus payout or multiplier that applies when the Super Bonus is active. Read it before you place the side bet, because the word "bonus" does not tell you whether the side bet is a good use of your stake. It only tells you that an extra payout exists under some condition.
Look for three things on the paytable. First, the trigger: what exactly must happen for the Super Bonus to pay. Second, the multiplier or fixed amount: how much the bonus adds, and whether it replaces the base payout or sits on top of it. Third, the cost of the side bet: whether it is a flat amount, a multiple of the base stake, or a separate stake you set yourself.
| Element | What it tells you | Where to find it |
|---|---|---|
| Trigger condition | The exact event that activates the bonus payout | Paytable or game rules screen |
| Bonus payout | The multiplier or fixed amount added to qualifying wins | Paytable, usually a separate column or line |
| Side bet cost | How much the Super Bonus wager costs per round | Bet selector or stake panel |
| Base paytable | Payouts when the bonus is not active | Paytable, standard column |
| Bonus paytable | Payouts when the bonus is active | Paytable, bonus column or separate table |
Some games show the two paytables side by side, which makes the comparison easy. Others only show the bonus paytable when you have the side bet selected. If you cannot see both at once, toggle the side bet on and off and watch how the displayed payouts change. That difference is what you are paying for.
Where the Super Bonus number comes from
Many Super Bonus versions designate one of the drawn numbers as the bonus number. The draw itself is produced by the same random number generator that produces the main keno draw. The bonus number is not a separate draw; it is one of the numbers already drawn, singled out by the game's rules as the one that activates the bonus.
This matters because it means the bonus condition is not an independent event you can influence. Your choice of spots does not change the probability that a particular number is drawn as the bonus number. If the bonus number is drawn from the same pool as the main numbers, every number on the board has the same chance of being the bonus number on any given round, regardless of which numbers you picked.
On games where the bonus activates on a high hit count instead of a specific number, the probability is driven by how many spots you chose and how many numbers the game draws. A high hit count is rarer than a low one, which is why the bonus payouts on those versions tend to be larger. The paytable reflects that rarity, but the rarity itself is fixed by the game's draw structure.
How to compare Super Bonus versions
Because the term "Super Bonus" is used by different game makers for different structures, two machines with the same name on the cabinet can play differently. The only reliable way to compare them is to read the rules screen and the paytable on each one. The name tells you a bonus exists. The paytable tells you what it does.
When you compare, treat the Super Bonus as a separate wager with its own expected return, not as an upgrade to the base game. A version where the side bet costs a small amount and pays a large multiplier on a rare event is a different proposition from one where the side bet costs a larger amount and pays a modest multiplier on a more common event. Neither is inherently better; they are different distributions of the same underlying mathematics.
Volatility also shifts. A Super Bonus that pays a large multiplier on a rare trigger increases the variance of the round. You will lose the side bet more often, but the occasional bonus win will be larger. A version with a smaller multiplier on a more common trigger produces more frequent but smaller bonus payouts. The long-run expected return is set by the paytable and the probabilities, not by how the bonus feels in a short session.
What Super Bonus does not change
The Super Bonus side bet does not change the probability of any keno number being drawn. It does not change the number of spots you pick or the number of balls in the draw. It does not make any number more likely to appear, and it does not make the base game return more than its paytable says it returns.
It also does not convert a losing base round into a winning one on most versions. The side bet settles on its own condition. If the bonus condition is tied to a hit count, a round with too few hits loses both the base wager and the side bet. If the bonus condition is tied to a specific number, the side bet can win even when the base wager loses, but that is a property of the specific version's rules, not a general feature of the name.
For a player deciding whether to add the side bet, the question is whether the extra cost is worth the changed payout distribution. The base keno game already has a house edge built into its paytable. The Super Bonus adds a second wager with its own edge. Playing both means your total expected loss per round is the sum of the expected loss on the base wager and the expected loss on the side bet, each calculated from its own paytable and probabilities.
FAQ
Is Keno Super Bonus a separate game or a side bet?
It is a side bet added to a standard keno round. The base game plays exactly as it would without the bonus, and the Super Bonus wager settles separately according to its own trigger condition and paytable.
Does the Super Bonus improve my chances of winning at keno?
No. The side bet does not change the probability of any number being drawn or any hit count occurring. It adds a second wager with its own house edge, so it changes the distribution of payouts and the total amount wagered per round, but it does not make the underlying keno game more favourable.
How do I find out what the Super Bonus pays on the game I am playing?
Open the paytable or rules screen on the machine or game client. Look for the bonus trigger condition, the bonus payout or multiplier, and the cost of the side bet. If the game shows separate base and bonus paytables, compare them directly to see what the side bet adds.
