Here's something that might surprise you: Singapore Pools launched computerized 4D betting on May 31, 1986, and the very first winning number was 8838—a combination featuring the lucky number "8" that still drives lottery enthusiasm today.
That's not a coincidence.
In this comprehensive guide, I'll walk you through everything you need to dominate Singapore 4D in 2026. You'll learn the exact prize structures, proven strategies, and how to use our free random number generator to make smarter picks.
Quick Navigation:
Let's dive in.
Singapore Pools 4D is a legal lottery game where you select a four-digit number from 0000 to 9999. Draws happen every Wednesday, Saturday, and Sunday at 6:30 PM, giving you three chances weekly to win.
Here's what makes 4D unique:
The game has been a cultural staple since 1966, offering fixed prize amounts (unlike variable jackpot games). This predictability means you know exactly what you're playing for.
In April 1993, 4D was tied to the Singapore Sweep draw—every first Wednesday of the month, winning numbers reflect the last four digits of the top 23 Singapore Sweep combinations.
1. Ordinary Entry (Standard Play)
Pick one 4-digit number. If it matches any of the 23 winning numbers, you win. Minimum bet: $1.
2. System Entry (Maximum Coverage)
Bet on ALL permutations of your chosen digits. For example, the number "1234" generates 24 unique combinations (4! = 24 permutations). Each combination costs $1, so a System Entry for "1234" costs $24 total.
Best for: Players who want comprehensive coverage of their favorite digits.
3. iBet (Budget-Friendly Permutations)
Similar to System Entry, but your prize is divided by the number of permutations. This makes it more affordable—you pay the cost of one entry, but cover all permutations with reduced winnings.
4. 4D Roll (Partial Wild Card)
Choose 3 specific digits and let the 4th digit be any number (0-9). This gives you 10 combinations. For "123R", you're betting on 1230, 1231, 1232... through 1239.
Cost: $10 for Big, $10 for Small (or $5 each if you choose one bet type)
5. Quick Pick (Pure Random)
Let the system randomly generate your numbers. No strategy required—just pure chance.
Here's the critical information most guides skip: the actual prize amounts.
According to Singapore Pools' official prize structure:
| Prize Category | Big Bet (Per $1) | Small Bet (Per $1) | Number of Winners |
|---|---|---|---|
| First Prize | $2,000 | $3,000 | 1 |
| Second Prize | $1,000 | $2,000 | 1 |
| Third Prize | $490 | $800 | 1 |
| Starter Prize | $250 | - | 10 |
| Consolation Prize | $60 | - | 10 |
Total winning numbers drawn: 23
Big vs. Small Bet Strategy:
Your iBet winnings depend on how many unique permutations your number has:
Big Bet iBet Prizes (Per $1)
| Prize Category | 4 Different Digits (1234) | 2 Different + 1 Pair (1123) | 2 Pairs (1122) | 3 Same Digits (1112) |
|---|---|---|---|---|
| Permutations | 24 | 12 | 6 | 4 |
| First Prize | $83 | $166 | $335 | $500 |
| Second Prize | $41 | $83 | $168 | $250 |
| Third Prize | $20 | $40 | $85 | $127 |
| Starter Prize | $10 | $20 | $41 | $62 |
| Consolation Prize | $3 | $6 | $10 | $15 |
Small Bet iBet Prizes (Per $1)
| Prize Category | 4 Different Digits | 2 Different + 1 Pair | 2 Pairs | 3 Same Digits |
|---|---|---|---|---|
| First Prize | $125 | $250 | $500 | $750 |
| Second Prize | $83 | $167 | $333 | $500 |
| Third Prize | $33 | $66 | $133 | $200 |
Pro Tip: Numbers with fewer permutations (like "1112") give you higher iBet payouts per winning combination.
Here's the truth about lottery number selection: All combinations have equal probability.
Whether you pick "1234" or "8888", your odds are identical: 1 in 10,000 for any specific number.
Our generator uses cryptographically secure randomization to produce truly unbiased 4D combinations. This eliminates two common player mistakes:
Singapore Pools provides historical statistics dating back to May 1986, showing that no number appears significantly more often than random chance would predict over time.
Use Random Generation When:
Use Personal Numbers When:
The Bottom Line: Both methods have identical odds. Choose what makes playing more enjoyable for you.
Let's be brutally honest about the mathematics:
For Standard Ordinary Entry (One Number):
For System Entry (All Permutations of "1234"):
Research shows lottery games have negative expected returns—the longer you play, the more you statistically lose.
Example calculation for $1 Big Bet:
Translation: For every $1 you bet, you can expect to get back approximately $0.66 over time.
The Takeaway: Play 4D for entertainment, not as an investment strategy. Set a budget and stick to it.
Won? Congratulations! Here's exactly what to do next.
Check official results at Singapore Pools or authorized retailers. Do NOT rely on third-party websites for official confirmation.
You'll need:
Critical: Photocopies or damaged tickets may not be accepted.
For prizes up to $5,000:
For prizes above $5,000:
You have 180 days from the draw date to claim your prize. After that, unclaimed winnings are forfeited.
Pro Tip: For prizes above $5,000, call ahead to confirm document requirements and avoid multiple trips.
The first computerized 4D draw in 1986 produced the number 8838, featuring the traditionally lucky number "8".
While every number has equal probability in each draw, historical analysis reveals:
"Hot Numbers" (Most Frequent in Recent Draws):
Recent hot combinations include 5807, 9395, 0400, 1845, 2967, 4678, and 4785
Important Note: Past frequency does NOT predict future results. These are historical observations only.
Players tend to avoid:
This creates a strategic opportunity: If you win with an "unpopular" number, you're less likely to share the prize with other winners... except that's not how 4D works. 4D offers fixed prize amounts regardless of the number of winners.
You can't change the mathematics, but you can optimize your approach:
Set a monthly entertainment budget. Treat 4D like any other leisure expense—never bet money you can't afford to lose.
Recommended: $20-50/month maximum
If you're only interested in significant wins, Small bets offer 50% higher payouts for the top three prizes. You sacrifice Starter and Consolation opportunities, but maximize headline winnings.
Pool money with friends to buy System Entries covering more numbers. Split winnings proportionally.
Example: 10 people contribute $10 each = $100 for multiple System Entries
Eliminate decision fatigue and bias. Generate fresh combinations for each draw.
Most players don't realize how much they spend cumulatively. Keep a simple log:
