Singapore
Lucky Singapore Sweep ticket number
Three 7-digit numbers built from your own chart: your favourable digits weighted in, the ones your chart works against removed. These are numbers to look for at the vendor, because the ticket already carries its number.
A number is only lucky relative to someone
Any site can add your digits up. Scoring the result against your own Day Master, Life Path and Kua number needs your birth moment.
What Singapore Sweep is
| Game | Numbers drawn | Jackpot odds |
|---|---|---|
| Singapore Sweep | Pre-printed 7-digit ticket | 1 in 10,000,000 |
Also pre-printed, a seven-digit ticket number you choose from what the outlet has, rather than a slip you fill in. A 7-digit ticket is one of exactly 10,000,000 possible numbers, so a given ticket takes the top prize at 1 in 10,000,000, no combinatorics involved, just the count of 7-digit numbers.
Elsewhere in the world
Same birth data, a different pool to fit it to. There is also every lucky-number calculator.
A ticket, not a form
Singapore Sweep sells pre-printed seven-digit tickets, so like the Thai lottery the number is chosen for you and the only decision left is which ticket you take off the counter. The generator above gives you something to look for rather than something to fill in.
Seven digits means ten million possible tickets, which is a cleaner piece of arithmetic than any draw game on this site: no combinations, no ordering, just a count. Whatever ticket you hold is one of ten million, and every other ticket in the country is exactly as likely.
Singapore Pools sells this and TOTO across the same counter, which puts a pick game and a no-pick game in front of the same customer. The only decision left on this one is how many tickets to take, and that scales your chance and your spend by exactly the same factor.
The four-digit version of the same idea, and the game Singapore plays far more of. Lucky 4D number.
This is a ticket game, not a pick game
Singapore Sweep tickets are pre-printed with a seven-digit number, so you are choosing from what the outlet already has rather than filling in a slip. A number here is one to look for, and if it is not on the shelf the closest match is the honest fallback.
The odds follow from that directly. There are ten million 7-digit numbers, so a given ticket taking first prize is 1 in ten million. Most prizes on these games come from matching only the last two or three digits, which is where nearly all realised winnings sit.
