A 10-spot keno ticket is the headline bet in the game: you pick 10 numbers and hope they land among the 20 numbers drawn. It offers the biggest advertised prizes, but it also carries the longest odds on the board. This guide gives you the exact chances of matching all 10, 9 or 8 of your numbers, explains why those odds differ between an 80-number casino game and Ontario’s 70-number Daily Keno, and shows what the top prize — such as OLG’s $250,000 on a $1 bet — really costs you in probability. Every figure here is checked against official and mathematical sources.
Key Points
- A 10-spot (10-Pick) keno ticket means you choose 10 numbers; the game draws 20 and pays on how many you match.
- Odds of matching all 10: about 1 in 8.9 million in an 80-number game, about 1 in 2.1 million in a 70-number game like OLG Daily Keno.
- Odds of matching 9: roughly 1 in 163,000 (80-ball) or 1 in 47,238 (OLG). Matching 8: roughly 1 in 7,384 (80-ball) or 1 in 2,571 (OLG).
- OLG Daily Keno 10-Pick top prize: $250,000 on a $1 bet, up to $2,500,000 on a $10 bet.
- A 10-Pick pays only on matching 10, 9, 8, 7 or 0 numbers — nothing for 1 through 6 matches.
- Overall chance of winning any prize on a 10-Pick: about 1 in 33, mostly from the $2 “match 0” tier.
What does “10-spot keno” mean?
A 10-spot (also written “10 Pick” or “10-spot keno”) is a keno ticket on which you choose exactly 10 numbers. The game then draws a fixed set of winning numbers — 20 of them in almost every modern version — and you are paid according to how many of your 10 picks appear in that draw.
The number of “spots” you play is simply how many numbers you mark. You can usually play anywhere from 1 to 10 spots (some casino versions go higher), and each spot count has its own prize ladder and its own odds. The 10-spot sits at the top of that range: the hardest to hit in full, but the one that carries the game’s largest jackpots. If you are still deciding how many numbers to mark, our guide to how to play keno walks through the full set of choices.
Two details decide your odds on a 10-spot: how many numbers are in the pool (70 or 80), and how many are drawn (almost always 20). Everything below follows from those two numbers.
What are the odds of matching all 10 numbers?
The odds of matching all 10 numbers on a 10-spot ticket are about 1 in 8.9 million in an 80-number game, and about 1 in 2.1 million in a 70-number game like Ontario’s Daily Keno. Catching all ten is by far the rarest outcome in keno, which is why it pays the jackpot.
The exact figures come from straightforward probability. In a classic 80-ball game where 20 numbers are drawn, the chance that all 10 of your picks are among those 20 is 1 in 8,911,711. In OLG’s Daily Keno, where the pool is only 70 numbers but 20 are still drawn, each of your picks is more likely to be caught, so the top-tier odds shorten to 1 in 2,147,181.
That gap matters. A smaller pool (70 versus 80) makes every match easier, so the same “match 10” result is more than four times more likely in Daily Keno than in a standard 80-ball game — which is also why the Daily Keno jackpot on a $1 ticket is smaller than some casino 10-spot top prizes.
What are the odds of matching 9 of 10?
Matching 9 of your 10 numbers happens roughly 1 in 163,000 times in an 80-ball game and about 1 in 47,000 times in a 70-ball game. It is the second-hardest result and usually the second-biggest prize on a 10-spot ticket.
In OLG Daily Keno, a 9-of-10 catch on a $1 ticket pays $5,000, at published odds of 1 in 47,238. In an 80-number game the same 9-catch is rarer, at 1 in 163,381, because the extra ten numbers in the pool make it harder for nine of your picks to all land.
What are the odds of matching 8 of 10?
Matching 8 of 10 is the first “realistic” big result on a 10-spot ticket: about 1 in 7,400 in an 80-ball game and roughly 1 in 2,600 in Ontario’s 70-ball Daily Keno. It is still uncommon, but you are far more likely to see it than a 9- or 10-catch.
On a $1 Daily Keno 10-Pick, catching 8 pays $200 at odds of 1 in 2,571. In an 80-number game, an 8-catch runs at 1 in 7,384. Notice the pattern: every time you drop one required match (from 10 to 9 to 8), the odds get dramatically shorter, which is exactly why mid-table prizes are smaller but win far more often.
Full 10-spot odds at a glance
The table below compares the odds of each catch on a 10-spot ticket in the two common formats: the classic 80-number game used in many casinos and online versions, and the 70-number format used by OLG Daily Keno. “Catch” means how many of your 10 numbers appear in the 20 drawn.
| Numbers caught (of 10) | 80-ball keno (odds) | 70-ball keno / OLG Daily Keno (odds) |
|---|---|---|
| 10 | 1 in 8,911,711 | 1 in 2,147,181 |
| 9 | 1 in 163,381 | 1 in 47,238 |
| 8 | 1 in 7,384 | 1 in 2,571 |
| 7 | 1 in 621 | 1 in 261 |
| 6 | 1 in 87 | 1 in 44 |
| 5 | 1 in 19 | 1 in 12 |
| 0 | 1 in 22 | 1 in 39 |
These are mathematical odds for the standard “20 drawn” format. Not every tier pays a prize — that depends on the operator’s prize table, which we cover next. For the broader picture across every spot count, see our full breakdown of keno odds and payouts.
OLG Daily Keno 10-Pick prizes and the $250,000 top prize
On OLG Daily Keno, a 10-Pick ticket pays prizes on only five outcomes: matching 10, 9, 8, 7, or 0 of your numbers. A $1 wager that matches all 10 wins the $250,000 top prize; the same ticket matching none of the 20 drawn numbers still returns $2.
Prizes scale with your bet. Because you can wager $1, $2, $5 or $10, the top prize ranges from $250,000 on a $1 play up to $2,500,000 on a $10 play. That $2.5 million figure is the “win up to” number OLG advertises for the game, and it is simply the $250,000 jackpot multiplied by a $10 stake.
The prize chart below shows the full $1 10-Pick ladder with OLG’s published odds for each tier.

Real jackpots do happen: OLG has publicised Daily Keno players collecting the $250,000 top prize on a $1, 10-Pick ticket that matched 10 of 10. But at 1 in 2.1 million per play, a 10-of-10 win is extremely rare, and the design of the prize ladder means most of a 10-Pick player’s returns actually come from the $2 “match 0” tier.
Why 80-ball and 70-ball keno give different odds
The single biggest factor in your 10-spot odds is the size of the number pool, because fewer numbers in the pool make every match easier. Ontario’s Daily Keno draws from 70 numbers, while the keno you find in many casinos, bars and online games draws from 80.
With 20 numbers always drawn, a 70-number pool means 20 of 70 numbers (about 29%) are “hot” each draw, versus 20 of 80 (25%) in the larger pool. That small difference compounds sharply across ten picks: the jackpot odds improve from 1 in 8.9 million to 1 in 2.1 million. Operators balance this by setting prize amounts accordingly, so the easier-to-hit 70-ball jackpot tends to carry a smaller headline figure.
The practical takeaway: never assume a 10-spot odds number you read online applies to your game. Always confirm whether it is an 80-ball or 70-ball format first. Keno is offered in several formats across the country, and you can see which games run where in our overview of keno across Canada.
What are your overall chances of winning anything on a 10-spot?
On an OLG Daily Keno 10-Pick, your chance of winning any prize on a single play is roughly 1 in 33. That overall figure is driven almost entirely by the “match 0” tier, which pays $2 and hits about 1 in 39 times on its own.
This surprises many players: on a 10-Pick you are more likely to win by matching none of your numbers than by matching seven or more. The reason is simple — with only 20 of 70 numbers drawn, avoiding all 20 with your 10 picks is uncommon enough to reward, yet still far more frequent than catching a large share of them.
Across an 80-ball game the “any prize” odds depend entirely on which tiers that operator chooses to pay. There is no single universal answer, which is why the prize table — not just the odds table — decides what a 10-spot ticket is really worth.
Common mistakes players make with 10-spot keno
The most common mistake is assuming a 10-spot gives you a meaningful shot at the jackpot. At 1 in 2.1 million (or 1 in 8.9 million in an 80-ball game), the top prize is a long shot by any measure, and no choice of numbers changes that.
- Treating “hot” or “due” numbers as an edge. Each draw is independent and random. Numbers that appeared recently are no more or less likely next time; past results carry no predictive weight.
- Mixing up 70-ball and 80-ball odds. Quoting a casino’s 1-in-8.9-million jackpot odds for Daily Keno (or vice versa) can be off by more than four times. Check the pool size first.
- Expecting every catch to pay. On a 10-Pick, matching 6, 5, 4, 3, 2 or 1 numbers pays nothing in Daily Keno. Only 10, 9, 8, 7 and 0 win.
- Chasing losses by raising the stake. Moving from a $1 to a $10 bet multiplies the prize but does nothing to improve your odds — and multiplies what you risk.
- Believing more spots always means better value. A 10-spot is not inherently “better” than a lower spot count; it simply trades frequent small wins for a rare large one. We cover this trade-off in our look at keno strategy.
Who is a 10-spot ticket for?
A 10-spot suits a player who is chasing the largest possible prize and accepts a very low chance of hitting it, not someone who wants frequent returns. It is the lottery-jackpot end of keno: big top prize, long odds.
If you prefer to win more often for smaller amounts, a lower spot count lands prizes far more frequently. If the appeal is the dream of a five- or six-figure payout from a small stake, the 10-spot is the ticket built for that — provided you treat the cost as entertainment spending, not an investment.
Responsible gambling
Keno is a game of pure chance with a built-in house edge, and a 10-spot ticket carries some of the longest odds in the game. No system, pattern or “due” number improves your chance of winning, and the odds are identical on every play regardless of past results. Prizes and prize tiers are set by the operator and can change; always confirm the current figures with the official game conditions before you play.

Frequently asked questions (FAQ)
What are the odds of matching all 10 numbers in 10-spot keno?
About 1 in 8.9 million in an 80-number game and about 1 in 2.1 million (1 in 2,147,181) in a 70-number game such as OLG Daily Keno. Catching all ten is the rarest result and pays the top prize.
How much does a 10-spot keno jackpot pay?
It depends on the game and your bet. On OLG Daily Keno a $1 10-Pick matching 10 of 10 pays $250,000, rising to $2,500,000 on a $10 bet. Casino and online 80-ball games set their own top prizes.
Do you win anything for matching 0 numbers?
In OLG Daily Keno, yes: a 10-Pick that matches none of the 20 drawn numbers pays $2 on a $1 bet, at odds of about 1 in 39. Whether a “match 0” pays in other keno games depends on that operator’s prize table.
Why are OLG Daily Keno odds different from casino keno?
Daily Keno draws from 70 numbers while most casino and online keno draws from 80. The smaller pool makes every match easier, so the Daily Keno jackpot odds (1 in 2.1 million) are shorter than an 80-ball game’s (1 in 8.9 million).
Can choosing certain numbers improve my 10-spot odds?
No. Every draw is independent and random, so no number, pattern, or “hot and cold” system changes your odds. The chance of matching 10, 9 or 8 is fixed by the game’s format, not by which numbers you pick.
