What is 4D?
4D (short for "4-Digits") is one of the most popular lottery games in Singapore and Southeast Asia. The concept is elegantly simple: choose a 4-digit number from 0000 to 9999, place your bet, and if your number matches one of the winning numbers drawn, you win a prize. The game has been a staple of Singapore's gambling culture for decades, with draws held three times every week.
In Singapore, 4D is operated by Singapore Pools — the only legal lottery and sports betting operator in the country. Singapore Pools 4D draws take place every Wednesday, Saturday, and Sunday at 6:30 PM, making it the most frequently drawn lottery game available to Singapore residents. This high draw frequency, combined with the straightforward gameplay and attractive prize ratios, makes 4D consistently one of the highest-revenue products for Singapore Pools.
The game draws 23 winning numbers each time: a 1st Prize, 2nd Prize, 3rd Prize, 10 Starter Prizes, and 10 Consolation Prizes. Players can choose between "Big" and "Small" bet types, which determine which winning categories they are eligible for. There are also variations like iBet (covering all permutations of a number) and 4D Roll (using a wildcard digit), which provide additional flexibility and strategic options.
4D carries deep cultural significance in Singapore and Malaysia. Many players choose numbers based on personal events — car plate numbers, house addresses, dates of birth, or even numbers encountered in dreams. This personal connection to the numbers makes 4D feel more intimate than purely random lotteries like Toto or the Sweep. Whether viewed as entertainment, a cultural tradition, or a hopeful investment, 4D remains a defining feature of Singapore's gaming landscape.
How to Play
Playing 4D is straightforward, making it accessible to complete beginners. Here is the step-by-step process:
Step 1: Choose a 4-Digit Number. Select any number from 0000 to 9999. This gives you 10,000 possible numbers to choose from. You can pick a number based on personal significance (birthday, anniversary, address), random selection, or any method you prefer. There is no statistical advantage to any particular number — every number has an equal chance of being drawn.
Step 2: Select Your Bet Type. Choose between a Big bet and a Small bet. A Big bet wins on all 23 prize categories (1st, 2nd, 3rd, Starter, and Consolation). A Small bet only wins on the top 3 prizes but pays out more for each. You can also choose iBet for permutation coverage or 4D Roll for wildcard betting.
Step 3: Decide Your Bet Amount. The minimum bet is SGD 1, and you can bet in whole dollar amounts. Your prize is calculated as a multiple of your bet amount — for example, if the 1st Prize Big payout is SGD 2,000 per SGD 1 bet, a SGD 5 bet would win SGD 10,000. You can place multiple bets on different numbers within the same draw.
Step 4: Purchase Your Ticket. Buy your ticket at any authorised Singapore Pools outlet, or online through the Singapore Pools website and mobile app. Fill out a 4D play slip with your chosen number, bet type, and bet amount. For online purchases, you need a registered and verified Singapore Pools account.
Step 5: Wait for the Draw. Draws are held on Wednesday, Saturday, and Sunday at 6:30 PM. You can check results on the Singapore Pools website, app, at outlets, or in newspapers the following day.
Bet Types: Big vs Small
The most fundamental decision in 4D betting is choosing between a Big bet and a Small bet. Each type offers a different risk-reward profile, and understanding the distinction is essential for every 4D player.
Big Bet: A Big bet wins if your chosen number matches any of the 23 winning numbers drawn — the 1st Prize, 2nd Prize, 3rd Prize, 10 Starter Prizes, or 10 Consolation Prizes. The advantage of a Big bet is that you have 23 chances to win. The trade-off is that the prize amounts are lower compared to a Small bet for the top 3 positions.
Small Bet: A Small bet only wins if your number matches the 1st, 2nd, or 3rd Prize — just 3 winning positions. The advantage is significantly higher payouts for these positions. The trade-off is that you have only 3 chances to win instead of 23.
| Prize Category | Big Bet Payout (per SGD 1) | Small Bet Payout (per SGD 1) |
|---|---|---|
| 1st Prize | SGD 2,000 | SGD 3,000 |
| 2nd Prize | SGD 1,000 | SGD 2,000 |
| 3rd Prize | SGD 490 | SGD 800 |
| Starter Prize (10 numbers) | SGD 250 | Not eligible |
| Consolation Prize (10 numbers) | SGD 60 | Not eligible |
The choice between Big and Small depends on your playing style. Conservative players often prefer Big bets because the 23 winning positions give more opportunities to win, even if the payouts are lower. Aggressive players may prefer Small bets, concentrating on the higher payouts of the top 3 positions. Many experienced players place both Big and Small bets on the same number to cover all scenarios.
For example, if you bet SGD 2 Big and SGD 1 Small on the number 5678, and it wins 1st Prize, you would receive SGD 4,000 (Big) plus SGD 3,000 (Small) = SGD 7,000 total. If the same number wins a Starter Prize, you would receive SGD 500 from the Big bet only, since the Small bet does not cover Starter Prizes.
iBet Explained
iBet (also called iBox in some contexts) is one of the most popular bet types among regular 4D players. It allows you to cover all possible permutations of your chosen 4-digit number within a single bet, significantly increasing your chances of matching a winning number.
How iBet Works: When you place an iBet, the system automatically generates all unique permutations of your 4-digit number. For example, if you choose the number 1234, the system generates all 24 possible arrangements: 1234, 1243, 1324, 1342, 1423, 1432, 2134, 2143, 2314, 2341, 2413, 2431, 3124, 3142, 3214, 3241, 3412, 3421, 4123, 4132, 4213, 4231, 4312, 4321. If any of these permutations matches a winning number, you win.
Permutation Count: The number of permutations depends on whether your 4-digit number has repeating digits:
| Number Type | Example | Permutations | iBet Cost (per SGD 1) |
|---|---|---|---|
| 4 unique digits | 1234 | 24 | SGD 1 (covers 24 at ~$0.042 each) |
| 1 pair of digits | 1123 | 12 | SGD 1 (covers 12 at ~$0.083 each) |
| 2 pairs of digits | 1122 | 6 | SGD 1 (covers 6 at ~$0.167 each) |
| 3 same digits | 1112 | 4 | SGD 1 (covers 4 at $0.25 each) |
iBet Prizes: Since an iBet spreads your bet amount across all permutations, the prize for each permutation is proportionally smaller. For a number with 24 permutations, the prize per permutation is 1/24 of the full prize. For example, if 1234 wins 1st Prize Big, a SGD 1 iBet would pay SGD 2,000 / 24 = SGD 83.33. If you had bet SGD 1 straight on 1234 (not iBet), you would receive the full SGD 2,000.
The appeal of iBet is clear: it dramatically increases your chances of matching a winning number without dramatically increasing your cost. For a number with 24 permutations, an iBet effectively gives you 24 chances to win for the price of one bet, albeit with proportionally reduced prizes.
4D Roll
4D Roll is an advanced bet type that uses a wildcard position in your 4-digit number. It is designed for players who want to cover a wider range of numbers systematically.
How It Works: In a 4D Roll, you select 3 specific digits and designate one position as a "Roll" digit (wildcard). The Roll digit cycles through all 10 possible values (0-9), generating 10 separate bets. For example, if you choose the number R234 (where R is the Roll position), the system generates: 0234, 1234, 2234, 3234, 4234, 5234, 6234, 7234, 8234, 9234.
Cost: A 4D Roll entry costs 10 times your base bet amount because it generates 10 separate bets. A SGD 1 4D Roll therefore costs SGD 10. You can place the Roll digit in any of the four positions — first, second, third, or fourth. Each position generates a different set of 10 numbers.
Combining Roll with iBet: You can also combine 4D Roll with iBet for maximum coverage. A Roll iBet generates 10 numbers from the Roll, and each number is further expanded into all its permutations through iBet. This creates extensive coverage but at proportionally increased cost and reduced per-permutation prizes.
Prize Structure
Understanding the complete 4D prize structure helps you evaluate the potential returns from your bets. Prizes are calculated as multiples of your bet amount, making it easy to scale up or down based on your budget.
| Prize Category | Numbers Drawn | Big Bet (per SGD 1) | Small Bet (per SGD 1) |
|---|---|---|---|
| 1st Prize | 1 | SGD 2,000 | SGD 3,000 |
| 2nd Prize | 1 | SGD 1,000 | SGD 2,000 |
| 3rd Prize | 1 | SGD 490 | SGD 800 |
| Starter Prize | 10 | SGD 250 | Not eligible |
| Consolation Prize | 10 | SGD 60 | Not eligible |
The prize amounts are fixed per SGD 1 bet and scale linearly with your bet amount. A SGD 5 Big bet on a number that wins 1st Prize would pay SGD 10,000 (5 x SGD 2,000). There is no pari-mutuel sharing — if multiple players bet on the same winning number, each receives the full prize based on their individual bet amount.
This fixed-payout structure is one of 4D's most attractive features compared to Toto, where large jackpots are shared among multiple winners. In 4D, your prize amount is guaranteed and known before the draw — the only variable is whether your number is drawn.
Draw Schedule
4D has the most frequent draw schedule of all Singapore Pools lottery products, with three draws per week:
Regular Draws: Every Wednesday, Saturday, and Sunday at 6:30 PM Singapore time (SGT/UTC+8). This three-times-weekly schedule means there is rarely more than two days between draws, keeping the game engaging for regular players.
Special Draws: Singapore Pools occasionally holds additional draws on public holidays and during festive periods such as Chinese New Year, Hari Raya, and National Day. These special draws are announced in advance and may feature additional promotional elements.
Ticket Sales Cut-Off: Sales close at 6:00 PM on draw days — 30 minutes before the draw. For online purchases through the Singapore Pools account, the cut-off is the same. Plan your purchases accordingly to avoid missing the deadline.
How to Check Results
4D results are widely accessible across multiple platforms immediately after each draw:
Singapore Pools Website: Full results are published at singaporepools.com.sg within minutes of the draw. The results page displays the 1st, 2nd, and 3rd Prize numbers, followed by the 10 Starter Prize numbers and 10 Consolation Prize numbers.
Singapore Pools Mobile App: The app provides push notifications for draw results and includes a ticket scanner for physical tickets. Simply scan your ticket barcode, and the app tells you instantly whether you have won.

Singapore Pools vs Other Operators
While Singapore Pools is the only legal 4D operator in Singapore, players in the region may encounter references to other 4D operators, particularly from Malaysia. Here is how they compare:
Singapore Pools 4D is the sole legal operator in Singapore. Draws are held on Wednesday, Saturday, and Sunday. The prize structure is well-established, and all operations are regulated under Singapore law. Bets placed with Singapore Pools are fully legal for anyone aged 18 and above within Singapore.
Magnum 4D is a Malaysian lottery operator. Magnum draws are held on Wednesday, Saturday, and Sunday. While Magnum is legal in Malaysia, placing bets with Magnum from Singapore may contravene Singapore's Remote Gambling Act if done through online channels. The prize structure differs slightly from Singapore Pools, with different payout ratios for some prize categories.
Sports Toto 4D is another Malaysian operator (distinct from Singapore's Toto lottery, which is a 6-from-49 game). Sports Toto draws are also held on Wednesday, Saturday, and Sunday. The same legal considerations apply for Singapore-based players.
For Singapore residents, Singapore Pools remains the only fully legal option for 4D betting. All Singapore Pools products are regulated, and your bets are protected under Singapore law. If you enjoy gaming beyond lottery products, you might also explore the best online casino Singapore options for a wider range of entertainment. For an understanding of what is legal and what is not, read our Toto Singapore guide or our Singapore Sweep guides for other legal lottery options. Always play responsibly and within your means.
Frequently Asked Questions
A Big bet wins if your number matches any of the top 3 prizes, 10 Starter prizes, or 10 Consolation prizes — 23 winning numbers total. A Small bet only wins if your number matches one of the top 3 prizes. Small bets have higher payouts (1st Prize SGD 3,000 vs SGD 2,000 per SGD 1 bet) but lower chances of winning because there are fewer winning positions.
iBet (also known as iBox) allows you to bet on all permutations of your 4-digit number at a reduced cost per permutation. For example, the number 1234 has 24 possible permutations. Instead of betting SGD 1 on each permutation (SGD 24 total), iBet lets you cover all 24 permutations for SGD 1 total, with the prize amount divided by 24. This increases your chances of winning while keeping costs manageable.
Singapore Pools 4D draws are held three times a week: every Wednesday, Saturday, and Sunday at 6:30 PM Singapore time. Additional special draws may be held on public holidays or during festive seasons. Results are published immediately on the Singapore Pools website and mobile app.
