Set For Life prize-tier and jackpot odds calculator
Choose Prize-tier odds for one line per draw, or Jackpot: multiple lines for different complete lines. Both modes calculate the chance across your chosen number of draws and the total ticket cost.
How many Set For Life combinations are possible?
Number selection
5 numbers from 1 to 47 + 1 Life Ball from 1 to 10.
Combination formula
C(47,5) × 10
Total full combinations
15,339,390
Set For Life uses 5 main numbers from 1 to 47 and 1 Life Ball from 1 to 10. The bonus part is selected separately from the Life Ball range. The total number of full top-prize combinations is 15,339,390.
Set For Life top-prize chance by unique lines
The table assumes every line is different in the same draw. Repeating a line does not cover another possible combination.
| Lines covered | Estimated ticket cost | Approximate chance | Equivalent odds |
|---|---|---|---|
| 1 unique line | £1.50 | 0.000006519% | 1 in 15,339,390 |
| 7 unique lines | £10.50 | 0.000045634% | 1 in 2,191,341 |
| 14 unique lines | £21.00 | 0.000091268% | 1 in 1,095,671 |
| 21 unique lines | £31.50 | 0.000136902% | 1 in 730,447 |
How the calculation works
For one unique line, the chance is:
1 ÷ 15,339,390 × 100
For several unique lines, the chance is:
number of unique lines ÷ 15,339,390 × 100
Example: with 7 unique Set For Life lines, the top-prize chance is 7 ÷ 15,339,390 × 100 = 0.000045634%.
Why unique Set For Life lines matter
If 14 Set For Life lines are planned but 3 of them repeat combinations already chosen by someone else, only 11 different top-prize combinations are covered.
Lottery-Checker cannot improve the official odds of any individual line. The practical benefit is organisation: if a line is already marked as used here, another player can choose a different line and cover a different combination instead of repeating the same one.
Check Set For Life results and plan new lines
The Set For Life results checker compares lines associated with this browser, or 1-7 lines you send for a one-off check that is not retained, with the latest published draw. After checking the result, use the shared board to plan new 5-number + 1 Life Ball combinations and avoid lines already marked here.

Frequently asked questions
Are these the chances of winning any prize?
Yes. Select Prize-tier odds, then choose Any prize for one line per draw. You can also select an individual prize tier. The separate jackpot mode and unique-line examples cover only the full top-prize match.
What do exactly and at least once mean?
An exact match outcome fixes the number of main matches and the stated special-ball condition in one round. For example, exactly 3 main matches does not include 4 or 5 main matches.
At least once across 10 draws means that the selected exact outcome occurs one or more times during those draws. It does not include outcomes with more matching numbers. The calculator does not calculate a separate chance of matching at least a chosen number of balls.
Any prize combines all paying match outcomes instead of selecting one exact outcome.
Why are lower-prize odds limited to one line per draw?
The chance of any prize across several lines depends on which numbers those lines share. A line count alone cannot determine that probability. The calculator therefore uses one line per draw for prize tiers and any-prize odds, and allows multiple different lines only for jackpot odds.
Does avoiding duplicate lines improve my odds?
It does not improve the odds of one individual line. It can help a group avoid repeating the same planned combination and cover more unique combinations.
Does marking a line buy a ticket?
No. Marking a line on Lottery-Checker is only a planning action. It does not buy a ticket or enter anyone into a draw.
Set For Life rules and a checking example
Choose 5 different main numbers from 1-47, plus 1 Life Ball from 1-10. Main-number order does not matter. The Life Ball comes from a separate pool and may equal one of the main numbers. Annuity payment terms, prize caps and eligibility are separate from the probability of matching the numbers.
Illustrative numbers, not an actual draw: Suppose the example result is 4, 13, 22, 31, 40 with Life Ball 7, and your line is 4, 13, 22, 31, 41 with Life Ball 7. The comparison is 4 main matches plus the Life Ball. Changing the Life Ball to 8 gives 4 main matches only.
Use the Set For Life checker for the latest comparison, or open the Set For Life results archive and select the date on your ticket. Compare each line separately.
Prize-tier probabilities for one line
For one line, the chance of exactly m main matches is C(k, m) × C(n - k, k - m) ÷ C(n, k), where n is the main-ball pool size and k is the number of main balls selected. Multiply by the independent special-ball match probability where applicable. Any-prize odds add the mutually exclusive winning match outcomes within one round.
The chance of any prize across several lines depends on which numbers those lines share. A line count alone cannot determine that probability. The calculator therefore uses one line per draw for prize tiers and any-prize odds, and allows multiple different lines only for jackpot odds.
Jackpot formulas and assumptions
C(n, k) = n! / (k! × (n - k)!)
N = C(47, 5) × 10 = 15,339,390
P(top-prize match in one draw) = u / N
Here n is the pool size, k is the number selected, and u is the number of distinct complete lines for one draw, from 0 to N. C(n, k) counts unordered selections without replacement. Multiplication assumes independent main and special-ball pools, with every valid outcome equally likely. Multiply a probability by 100 to obtain a percentage.
Across d independent draws with the same number u of different lines each time, the chance of at least one top-prize match is 1 - (1 - u/N)d. Repeating a line within one draw does not increase u.
For a selected prize tier or any-prize outcome with probability p in one draw, the chance of that outcome at least once across d independent draws is 1 - (1 - p)d. Prize-tier mode uses one line in every draw. Ticket cost is the price per line multiplied by lines per draw and number of draws.
Probabilities are calculated from the game structure, with displayed odds rounded. Prize labels describe the relevant match tier, not expected profit. Raffles, optional extras, jackpot sharing, tax and the present value of annuity payments are outside these calculations. Past results and marks on the shared board do not change the odds.
