Stake Keno Calculator: Odds, Payout, RTP and Expected Value
Choose a saved difficulty table, set the target matches and stake, and calculate the payout, chance of no payout and full-table expected value. Eight presets cover Classic, Low, Medium and High for 7 or 10 picks. For another selection, enter its complete paytable.
Calculate odds and payout
The selected hit count looks up its multiplier directly from the table. To test another payout, edit that table row. A multiplier is the total return: 1× returns the stake, and a return below 1× is a net loss even though it pays something.
Classic · 7 picks · saved multipliers dated 6 July 2026.

Calculator results
Results use the selected table and stake.
No payout limit is modeled unless entered.
EV is an average net result under the entered rules. It does not predict a session balance. Amounts exclude fees, taxes and bonuses.
One-outcome EV illustration
This separate model sets every payout except the selected hit count to zero. It is not the full-game EV shown above, unless all other outcomes actually pay zero.
Using a different pick count or difficulty? Match the complete paytable to that selection before comparing payouts.

Paytable RTP and payout frequency
Any payout includes partial returns and stake returns. Net profit requires a return greater than the stake. Total wagered is stake × rounds, not an initial deposit.
Compare with the published 99% RTP
A benchmark is separate from the entered paytable.
Why calculated RTP can differ from 99%
The public Originals page states 99% RTP. This tool calculates return from the individual multipliers entered in the table. Those are different inputs: a headline percentage cannot replace a missing or different payout line.
The eight saved tables yield 98.7597%–99.0374% before limits. That range is close to 99%, but does not reproduce it exactly. The displayed values alone do not establish whether rounding, a table change or another rule accounts for the difference.
Use full-table EV for the configuration entered here. The optional 99% comparison answers a separate question: what would the expected result be if return were exactly 99%? For 1,000 units wagered, that benchmark gives 10 units of expected net loss.
Saved paytables: Classic, Low, Medium and High
These eight tables carry the snapshot date . They remain available for reproducible calculations and comparison; their multipliers are not labeled as current live values. Each return below uses a 40/10 draw with no modeled payout limit.
| Difficulty | RTP — 7 picks | Edge — 7 picks | RTP — 10 picks | Edge — 10 picks |
|---|---|---|---|---|
| Classic | 98.9815% | 1.0185% | 99.0374% | 0.9626% |
| Low | 98.9388% | 1.0612% | 98.7597% | 1.2403% |
| Medium | 98.9618% | 1.0382% | 98.9743% | 1.0257% |
| High | 98.9618% | 1.0382% | 99.0083% | 0.9917% |
A difficulty label describes the payout structure, not a promise of lower expected loss. In this saved set, Low with 10 picks has a higher calculated house edge than High with 10 picks. This comparison does not establish which table is available in a current game session.
For a fixed pick count, changing difficulty leaves exact-hit probabilities unchanged. It changes which outcomes pay and how much they return. For example, the saved seven-pick Low table pays from two hits, while High pays from four. The calculator sums the actual paying rows, including zero-hit prizes or gaps if entered in a custom table.
Match the game to the calculator
The presets on this page model Stake Originals Keno. A provider game needs its own number pool, draw size and paytable, even when its title includes Keno.
Inputs that affect the result
- Original or provider version.
- Current RTP and house edge notice.
- Risk mode or paytable variant.
- Maximum payout and bet limits.
- Whether the limit applies to gross return or net profit.
Worked payout examples
Each example uses the saved seven-pick table, a 40/10 draw and a stake of 10 units with no payout limit. Payouts refer to exactly the listed matches.
| Saved table / result | Exact probability | Multiplier | Gross return | Net profit / loss |
|---|---|---|---|---|
| Classic · 2 of 7 | 34.3967% | 0.47× | 4.70 | -5.30 |
| Classic · 3 of 7 | 17.6393% | 3× | 30.00 | +20.00 |
| High · 4 of 7 | 4.5732% | 7× | 70.00 | +60.00 |
Two matches on Classic return 4.70 from a 10-unit stake, leaving a 5.30 loss. That outcome counts as a payout, but not as net profit. Across the full Classic seven-pick table, the no-payout probability is 42.7684% and the chance of net profit is 22.8349%.
The same full table calculates to 98.9815% RTP. Over 100 rounds at 10 units each, expected net loss is approximately 10.18 units. A session can finish far above or below that expectation; the figure is not a loss limit.
RTP contribution by hit count
Each row is a mutually exclusive exact-hit outcome. Its RTP contribution is probability × effective total-return multiplier, expressed in percentage points. Where an entered limit reduces a payout, both nominal and effective multipliers are shown.
| Hits | Exact probability | Odds | Multiplier | Gross payout | RTP contribution |

How this calculator works
The calculator models a uniform draw of distinct numbers without replacement. For Stake Originals, the pool has 40 numbers and the draw contains 10. Matching exactly h of your picks follows the hypergeometric distribution.
P(h hits) = C(picks, h) × C(pool − picks, drawn − h) / C(pool, drawn)
C(a, b) counts combinations. “At least h” sums the exact probabilities from h upward. Full RTP uses exact probabilities only; using overlapping at-least probabilities would count some outcomes more than once.
For each hit count, gross return is stake × multiplier, reduced by any entered limit. A net-profit limit L corresponds to a gross ceiling of stake + L. RTP sums probability × gross return / stake across the complete table; net EV per round is stake × (RTP − 1).
Hit probabilities
Odds are controlled by number pool, draw size, pick count and target hits. They do not change because the payout table changes.
Payout multipliers
The paytable controls how much each hit count returns. This is where risk modes and operator versions matter.
Complete-table return
RTP includes all paying outcomes. A single line gives the complete return only when every other outcome pays zero.
Stake Originals and other Keno games
The 40/10 presets apply to the saved Originals tables. The illustrative 80/20 option is a separate mathematical example, not another Stake Originals difficulty. Likewise, a provider’s Keno title needs its own format, prizes and additional rules.
A standard hit-count table cannot fully describe a game where payout also depends on draw order, a bonus ball or a progressive jackpot. Those features require their own probability model. For another basic draw format, use the crypto Keno calculator or the general odds calculator.
Can a calculator predict Stake Keno numbers?
No. Under the uniform-draw model, every set with the same number of picks has the same hit distribution. Changing the chosen numbers or using a “hot numbers” list does not change those probabilities. The calculator evaluates payout rules and expected value; it does not reveal future draws.
Changing difficulty affects payouts, not the probability of matching a fixed number of picks. A higher top multiplier alone says nothing about full RTP or the chance of finishing a session in profit.

Sources and table dates
Stake’s public Keno page was checked on for the 40/10 format, pick range and stated 99% RTP. The eight saved paytables carry a separate date of 6 July 2026. They have not been reverified against the live game for this update.
All table RTP, payout probabilities and EV examples on this page are calculated from the displayed inputs using the hypergeometric model. They are not operator-certified returns for the saved tables. No fixed maximum bet, maximum profit or current promotional return is assumed.

Frequently asked questions
What does the Stake Keno calculator calculate?
It calculates exact-hit and at-least-hit probabilities, payouts, full-paytable RTP, house edge and expected net results. Eight saved tables cover Classic, Low, Medium and High for 7 or 10 picks; other selections require their own complete table.
Is this an official Stake calculator?
No. KenoCalc.com is independent and is not operated by Stake. The saved presets are dated 6 July 2026 and are not a live feed of current multipliers.
What RTP does Stake Keno state?
The public Stake Originals Keno page states 99% RTP and 1% house edge. The calculator separately computes return from the entered multipliers, which may differ from that headline percentage.
Does a payout always mean a profit?
No. A total-return multiplier below 1× returns less than the stake. In the saved Classic seven-pick table, two hits pay 0.47×, so a 10-unit stake returns 4.70 and loses 5.30 net.
Do Low and High difficulty change the hit odds?
For the same number pool, draw size and picks, exact-hit probabilities stay the same. Difficulty changes which hit counts pay and the multipliers assigned to them.
Can I calculate another pick count?
Yes. Enter the pick count and its complete paytable, including zero-paying outcomes. The 40/10 model accepts 1–10 picks, but the saved presets cover only 7 and 10. Do not reuse a different pick count’s table.
How are maximum payouts handled?
The optional limit can apply to gross return or net profit. A gross limit includes the returned stake; a net-profit limit does not. The entered limit is applied to each outcome. Leaving it blank models no limit and does not verify the game’s maximum award.
Can this calculator predict future Keno numbers?
No. It evaluates probabilities and payout rules. Under a uniform independent draw model, previous results do not give a same-sized selection of numbers better odds in the next round.
