How Singapore TOTO Works: A Beginner's Guide

A plain-English introduction to the draw format, the Additional Number, and how prizes are grouped — before you look at a single statistic.

What Is Singapore TOTO?

Singapore TOTO is a numbers lottery operated by Singapore Pools. Draws are held twice a week, on Monday and Thursday, at 6:30pm Singapore Time, with ticket sales closing at 6:00pm on the draw day (draws are occasionally shifted around public holidays, so it is always worth confirming the exact schedule on singaporepools.com.sg).

Each draw uses a pool of numbers from 1 to 49. A ticket entry picks 6 numbers from that pool, and the draw machine selects 6 Winning Numbers plus one further number, the Additional Number, from the remaining 43.

How a TOTO Draw Works

On draw day, 7 numbers are drawn in total from the 1–49 pool: 6 Winning Numbers first, then 1 Additional Number from what is left. Every number in the pool has an equal chance of being drawn — the mechanical process does not favor any number, and nothing about a past draw changes the odds of the next one.

What you see published after a draw — the draw number, the date, the 6 Winning Numbers, the Additional Number, and the prize breakdown — is the complete official record for that draw. This site rebuilds its entire dataset directly from that published record.

The 6 Winning Numbers

The 6 Winning Numbers are the core of every TOTO entry. An entry that matches all 6 in any order wins the top prize group. Matching fewer of the 6 — sometimes combined with the Additional Number — can still win a smaller prize group, which is why TOTO has multiple prize tiers rather than a single winner-take-all outcome.

What Is the Additional Number?

The Additional Number is a single extra number drawn from the same 1–49 pool, after the 6 Winning Numbers. It is not one of your 6 chosen numbers — it exists purely to help sort entries that already matched some Winning Numbers into the correct prize group. We cover this in more depth in a dedicated article: What Is the Additional Number in Singapore TOTO?

Prize Groups at a Glance

TOTO results are organized into prize groups, from Group 1 (the jackpot, for matching all 6 Winning Numbers) down to Group 7 (the smallest prize tier). Each group has its own matching rule, and some groups use the Additional Number as part of that rule. The exact mechanics are explained separately in Singapore TOTO Prize Groups Explained and in this site’s Guide.

How to Check the Results

Every official draw — draw number, date, Winning Numbers, Additional Number, and the full prize table — is available on this site’s Results page, alongside a searchable historical archive. See How to Read Singapore TOTO Results for a walk-through of what each field means.

What This Site Is (and Isn’t)

SG TOTO SmartPick is not a ticket seller and has no affiliation with Singapore Pools. It is a number generator and statistics tool built on official historical draw data. The historical patterns shown across this site — frequency, hot/cold numbers, sums, and so on — describe what has already happened; they are not a prediction of what will happen in the next draw. Every draw is an independent, random event.
