Keno
Banco Special Odds and Prizes Explained
Banco spécial is a Loto-Québec keno game where one selection plays twenty numbers at once. The table above shows every catch with its odds and prize, with and without Turbo.
You play all 20 spots of a 70-number board and 20 numbers are drawn. The most likely catch is 6; catches of 4 to 7 pay nothing, while catching very few pays, like catching many.
Loto-Québec prints the chance of any prize as 1 in 4.12; the exact figure is 1 in 4.12.
Catching none of the 20 pays $500: it happens about once in 3,435 draws.
$10,000,000 is the most paid per prize category in one draw, shared by all winners of that category. A sole winner is never cut at this bet, so the return assumes one winner.

How the return is counted
Return per $1 = sum over every catch of (chance of that catch times prize) / price.
Expected prize = $2.51; price = $5; 50.17%
Every chance is an exact fraction (whole-number counts of tickets), rounded only for display.
Show the formula
Chance of catching exactly 0 of your 20 spots when 20 numbers are drawn from 70:
P(0) = C(20,0) × C(50,20) / C(70,20)
= 1 × 47,129,212,243,960 / 161,884,603,662,657,900 = 1 in 3,435
C(n,k) is the number of ways to choose k numbers out of n. The first factor picks which drawn numbers are yours, the second picks your other spots among the numbers not drawn.

Questions
How does Banco spécial work?
One selection is twenty numbers from one to seventy and costs $5. Loto-Québec draws twenty numbers every evening. Catching 0 to 3 of 20, or 8 of 20 or more, pays a prize.
What are the odds of winning a prize in Banco spécial?
The odds of any prize are 1 in 4.12. The top prize, for 15 to 20 of 20, has odds of 1 in 4,763,044. On average 50.2% of the price comes back as prizes.
Does the Turbo option change the odds in Banco spécial?
No. Turbo doubles the cost and multiplies the prize by a multiplier from a separate draw. The chance of each catch stays the same; only the prize and the average return change.
Where can I see Banco spécial results?
Draw results are published by Loto-Québec, the organiser. This page shows odds and prizes, not results. Past results do not change the odds of the next draw.
How is Banco spécial different from Banco?
In Banco you play fewer numbers and choose your wager. Banco spécial always plays twenty numbers at a fixed price of $5.
