4D Singapore

What 4D is

4D is Singapore's four-digit lottery. You pick a number from 0000 to 9999, decide how much to stake, and wait for the draw. Each draw produces 23 winning numbers: the top three prizes, ten Starter Prizes and ten Consolation Prizes. If your number matches one of them, in the right way for your bet type, you win².

Singapore Pools runs 4D, along with TOTO, Singapore Sweep and the country's sports betting. It is one of the most popular forms of betting in Singapore, and it is woven into everyday life: you will see queues at outlets on draw days and people checking results at hawker centers and coffee shops².

The game has a long history. In April 1993 the 4D draw was tied to the Singapore Sweep draw, and every first Wednesday of the month the 4D winning numbers are still drawn this way, as the last four digits of the top 23 winning Singapore Sweep combinations. A Wednesday draw day was added on August 9, 2000, giving the game its current three-draws-a-week rhythm⁵.

4D is a fixed-odds game in the sense that the payout for each prize level is set in advance, so you know what your bet will pay before the draw. The one thing you do not know, of course, is whether your number will come up.

Draw days and closing time: Wednesday, Saturday and Sunday

4D draws are held three times a week, on Wednesday, Saturday and Sunday, at 6.30pm³. So whatever day it is today, the next draw is simply the next of those three days.

Sales for each draw close at 6pm on draw day, both online and at outlets, giving a half-hour gap before the draw itself¹. If you are the kind of bettor who leaves things to the last minute, that 6pm cutoff is the number to remember.

You do not have to bet only for the current draw. At outlets you can bet on any of the current Wednesday, Saturday or Sunday draws, or on six consecutive draws including the current one, all on a single bet slip¹. That means one trip to the outlet can cover two full weeks of draws on the same numbers.

One special case: on the first Wednesday of each month, the 4D draw is tied to the Singapore Sweep draw, and the 4D winning numbers come from the Sweep results rather than a standalone 4D draw⁵. The draw time and the sales closing time are unchanged.

Bet types: Ordinary, iBet, 4D Roll, System Entry and Quick Pick

There are several ways to place a 4D bet, and the type you choose determines both the cost and how your number has to match the draw⁵.

Ordinary. You select four digits in a specific order, for example 3-7-1-8. Your bet wins only if that exact sequence matches a winning number in the exact order drawn. On a bet slip, you mark the four digits and your stake; no bet type box needs to be marked for an Ordinary bet⁵.

iBet. You pick the same four digits, but the bet covers all permutations of them. If your digits are 3-7-1-8, you are covered whether the draw produces 3-7-1-8, 8-1-7-3 or any other arrangement. Because it covers every ordering, iBet costs more than a single Ordinary bet, and the payout per winning combination is lower. It suits bettors who care about the digits but not the order.

4D Roll. You select three digits and one rolling digit, written as "R". The R stands for any number from 0 to 9, so one Roll bet covers ten numbers at once, and the total stake is your marked stake multiplied by 10⁵. Only one of the four digits can be a rolling digit. For example, 3-R-1-8 covers 3-0-1-8 through 3-9-1-8.

System Entry. You select four digits and place bets on all their permutations, as separate Ordinary bets⁵. On the bet slip this is the Full System Bet: you mark four digits, and the total stake is your marked stake multiplied by the number of Ordinary combinations those digits produce⁵. Four different digits give 24 permutations; repeated digits give fewer. Unlike iBet, each permutation pays the full Ordinary prize if it wins.

Quick Pick. If you have no numbers in mind, Quick Pick lets the system generate your four digits for you. It is available online and in the app alongside the self-pick bet types⁶.

Online and in the app, you can place self-pick bets for these bet types¹:

• Ordinary
• 4D Roll
• System Entry
• iBet

A physical bet slip at an outlet holds up to four number combinations of the same bet type, so if you want more numbers or mixed bet types, you use more than one slip⁵.

Prize structure: 1st, 2nd and 3rd plus Starter and Consolation Prizes

Every 4D draw produces 23 winning numbers, drawn from 0000 to 9999²:

The 1st, 2nd and 3rd Prizes are the headline wins. The ten Starter Prizes and ten Consolation Prizes give you twenty more chances per draw, at lower payouts, which is why a number can win something even if it is not the top number of the night².

How your bet matches these numbers depends on your bet type. An Ordinary bet must match a winning number exactly, digit for digit in order. iBet and System Entry cover the permutations, so they can win when the digits match in any order, but each winning permutation pays less than an Ordinary bet would.

Top prize: SGD 2,000 per SGD 1 bet

The headline payout is S$2,000 for every S$1 staked on a Big bet that hits the 1st Prize³. Press coverage of the game puts top payouts at between S$2,000 and S$3,000 per S$1 bet depending on the prize level and bet type².

The minimum stake is S$1, and stakes are placed in multiples of S$1. A S$5 Big bet on the 1st Prize would pay S$10,000 at the S$2,000-per-S$1 rate. Smaller bet types scale the same way but at reduced payouts per combination: an iBet win, for instance, spreads the prize across the permutations covered, and a Roll bet's ten covered numbers each carry a share of the total stake.

For comparison, the other big Singapore Pools lotteries pay differently: Singapore Sweep's first prize was S$2,300,000 in the September 2026 draw⁷, and TOTO's Group 1 prize is 38% of the prize pool with a guaranteed minimum of S$1,000,000. 4D stands apart because its payouts are fixed per dollar staked rather than pooled.

Odds of winning: 23 winning numbers out of 10,000

There are 10,000 possible four-digit numbers, from 0000 to 9999, and each draw produces 23 winning numbers: the top three, ten Starter and ten Consolation². That means every ticket has a 23 in 10,000 chance of winning something².

Put differently, a single Ordinary bet has a 1 in 10,000 chance of hitting the 1st Prize exactly. The odds are the same for every number: 0000 is neither more nor less likely than 8888, whatever folklore at the outlet says.

The bet types change how those odds are spread, not the underlying math. A Roll bet or a System Entry covers many combinations at once, so your chance of matching something rises, but your total stake rises by the same proportion and the payout per combination falls for the cheaper covering types like iBet. The 23-in-10,000 figure is the honest summary of the game: most draws, most tickets, win nothing.

How to bet: online, app or outlets

There are three main ways to place a 4D bet⁸:

At an outlet. You fill in a paper bet slip: mark your four digits, your bet type where needed, and your stake in the Big and Small boxes. For an Ordinary bet or a Roll bet, no bet type box needs to be marked⁵. Hand the slip and payment to the counter staff, and you receive a ticket. Check the details on the ticket before you leave and keep it safe: it is the only proof of your bet, and bets placed at outlets cannot be tracked or recovered if you lose the ticket⁴. Outlets accept cash, ATM card, debit card with NETS function and PayNow⁴.

Online. Betting online requires a Singapore Pools Account, which is also the only way to track your bets and see your transaction history⁴. Online you can place self-pick bets for Ordinary, 4D Roll, System Entry and iBet for draws on Wednesday, Saturday or Sunday⁶.

In the app. The Singapore Pools mobile app gives you the online betting services plus lottery results, and it can replace the paper bet slip entirely: you generate a QR code for your bet and scan it at any outlet to complete and pay for the bet, with no sign-up required for that function⁹. The app also lets you save your regular 4D and TOTO numbers for quicker re-betting⁹.

One quirk worth knowing about claiming prizes: after 6.05pm, prizes cannot be claimed on the same day as an undrawn date on a multi-draw ticket¹⁰. So if you hold a six-draw ticket and win on an early draw, claim before 6.05pm or come back another day for the same-day claim.

Favorite numbers and combining bet types

Two features make regular 4D betting quicker once you are set up online or in the app.

Favorite numbers. You can save up to 20 sets of 4D favorite numbers in your account or the app¹. If you always bet the same numbers, your car plate, your flat number, a birthday, you enter them once and re-bet them in a few taps instead of marking a fresh slip each time.

Multiple bet types on one board. In the app, you can place multiple bet types on the same 4D number within the same board, instead of entering each one separately¹. So if you want 3-7-1-8 as both an Ordinary bet and an iBet, you can do it in a single entry. The exception is 4D Roll, which cannot be combined this way and needs its own entry¹.

A related trick at outlets: marking the SG SWEEP box on a 4D bet slip makes the same 4D number the last four digits of a Singapore Sweep entry, for Ordinary bets only⁵. It is a quick way to enter both games with one set of digits, though the Sweep itself is a separate game with its own prize structure.
