How Lucky 15 Works
Lucky 15 is a lottery game where players select 15 numbers from a pool of 30 numbers (1-30). The game draws 15 winning numbers each week. Players can match 0 to 15 numbers to win prizes.
The odds of winning depend on how many numbers you match:
| Numbers Matched | Odds | Payout |
|---|---|---|
| 15 | 1 in 15,503,775 | Jackpot |
| 14 | 1 in 1,086,328 | £10,000 |
| 13 | 1 in 59,549 | £1,000 |
| 12 | 1 in 2,740 | £100 |
| 11 | 1 in 105 | £10 |
| 10 | 1 in 12 | £5 |
Players can choose to play with a single line or multiple lines. Each line costs £1, and the jackpot grows with each unclaimed week.
Calculator Formula
The calculator uses the following formulas to determine your odds and potential winnings:
Odds Calculation
The probability of matching exactly k numbers is calculated using the hypergeometric distribution:
P(k) = [C(15,k) × C(15,k)] / C(30,k)
Where C(n,k) is the combination of n items taken k at a time.
Payout Calculation
Potential winnings are calculated as:
Winnings = Bet Amount × Payout Multiplier
The payout multipliers are based on William Hill's current prize structure.
Example Calculation
Let's say you bet £5 and match exactly 12 numbers:
Example Scenario
Bet Amount: £5
Numbers Matched: 12
Odds: 1 in 2,740 (≈0.0364%)
Payout: £100
Potential Winnings: £5 × 20 = £100
This means you have a 0.0364% chance of winning £100 for each £5 bet when matching exactly 12 numbers.
