Back in 2022, the PCSO 6/42 jackpot crept past ₱100 million. The office buzz was everywhere. I sat down one night with a calculator, typed in the combination formula, and stared at what came back.
The number was 5,245,786.
That is the formula for the lottery: not a secret code, not a pattern. Just a count of how many different ways you can pick 6 numbers from 42. This post breaks down that number, compares all five major PCSO games, and explains why every “lotto formula” you have ever heard is really just math in disguise.
What is the formula for the lottery?
The lottery uses a combination formula: C(n,r) = n! ÷ (r! × (n-r)!)
For PCSO Lotto 6/42, plug in n=42 and r=6. The result: C(42,6) = 5,245,786 possible combinations. One of those combinations wins each draw. Your ticket covers exactly one of them.
| Formula element | Value |
|---|---|
| Formula | C(n,r) = n! ÷ r!(n-r)! |
| PCSO Lotto 6/42 result | 5,245,786 combinations |
| Your jackpot odds per ticket | 1 in 5,245,786 |
| Current ticket price (2025) | ₱25 |
In this formula, order does not matter. Picking 7-14-23-31-38-42 is the same combination as 42-38-31-23-14-7. The formula counts unique groups, not arrangements. So all those “lucky patterns” people build their picks around? Each one holds exactly 1 of the 5,245,786 slots.
How the 6/42 odds play out in real life
What 1 in 5,245,786 actually looks like
When I first computed this number, it was hard to picture. Here is one way to feel it: if you played one unique combination every single day without repeating, it would take you over 14,300 years to cover every possible combination.
That is your competition. Per ticket.
The lower prize tiers are more reachable, but they come with their own reality check.
| Match | Odds | Approximate prize |
|---|---|---|
| 6 of 6 | 1 in 5,245,786 | Min ₱10M jackpot |
| 5 of 6 | 1 in 24,286 | Varies per draw |
| 4 of 6 | 1 in 555 | ₱2,000 |
| 3 of 6 | 1 in 37 | ₱20 |
Look at that 3-of-6 prize. The odds are 1 in 37, far better than the jackpot. But the prize is only ₱20 – and you spent ₱25 on that ticket. You are still down ₱5 after matching three numbers.
Still, real people do win the jackpot. A 6/42 winner from Pateros once bagged ₱25 million from a single ticket. The math just says that happens to one person in every 5.2 million who plays.
How all 5 PCSO lotto games compare
Which game gives you better odds?
Lotto 6/42 is the “easiest” major jackpot game. As the number pool grows, the combinations multiply fast and your odds shrink.
| Game | Combinations | Jackpot odds | Min jackpot | Draw days |
|---|---|---|---|---|
| Lotto 6/42 | 5,245,786 | 1 in 5.2M | ₱10M | Mon/Wed/Fri |
| Mega Lotto 6/45 | 8,145,060 | 1 in 8.1M | ₱15M | Mon/Wed/Fri |
| Super Lotto 6/49 | 13,983,816 | 1 in 14M | ₱25M | Tue/Thu/Sun |
| Grand Lotto 6/55 | 28,989,675 | 1 in 29M | ₱45M | Mon/Wed/Sat |
| Ultra Lotto 6/58 | 40,475,358 | 1 in 40.5M | ₱75M | Tue/Fri/Sun |
Sources: Wikipedia – PCSO Lottery Draw, PCSO; Super Lotto 6/49, PCSO – Ultra Lotto 6/58
Moving from 6/42 to Ultra Lotto 6/58 makes your odds nearly 8 times worse. Even a bettor from Iloilo who hit the ₱49.5M Ultra Lotto jackpot was fighting 1-in-40.5M odds. The bigger jackpot comes with a much steeper price in probability.
When does a harder game make sense?
When a jackpot rolls over many times, the prize pool grows. At some point, the higher payout slightly improves the expected value despite worse odds. For most players, however, the difference is minor. You are still comparing “very close to zero” with a slightly different “very close to zero.”
Does buying more tickets actually help?
Yes, in theory. Barely, in practice.
One ticket: 1 in 5,245,786. One hundred tickets: roughly 1 in 52,458. That is a 0.002% chance. To guarantee a jackpot win, you would need to buy all 5,245,786 combinations. At ₱25 each, that is ₱131 million in tickets for a jackpot that starts at ₱10 million.
| Tickets bought | Your odds | Total cost |
|---|---|---|
| 1 | 1 in 5,245,786 | ₱25 |
| 10 | 1 in 524,579 | ₱250 |
| 100 | 1 in 52,458 | ₱2,500 |
| 1,000 | 1 in 5,246 | ₱25,000 |
| 10,000 | 1 in 525 | ₱250,000 |
A friend once bought 100 tickets for a big 6/42 draw, fully convinced he was “malakas na.” The math showed him he had spent ₱2,500 to move from statistically impossible to still statistically impossible.

The “patterns,” hot numbers, and system bets; debunked
Why patterns do not work
The most popular “lotto formula” in Filipino culture is the pattern method. Consecutive numbers (1-2-3-4-5-6), multiples of 3, diagonal lines on the bet slip, people treat these as secret codes. The combination formula counts every unique group of 6 equally. As a result, 1-2-3-4-5-6 has exactly the same 1-in-5.2M odds as 4-17-23-29-35-41. Your pattern is one of 5,245,786.
Why hot numbers and birthday picks hurt you
In fact, each draw is completely independent. The machine does not remember last Tuesday’s results. So “hot numbers”: combinations drawn recently, carry zero extra probability. Birthday picks are even worse: you limit yourself to numbers 1-31, cutting out 11 numbers (32-42) entirely. You are playing with a shorter deck for the same ₱25 ticket price.
Why system bets can backfire
System bets cover more combinations within your chosen set. System 7 gives you 7 tickets instead of 1, which genuinely improves coverage. However, it costs 7 times more, and if your set overlaps with popular combinations, you risk splitting the jackpot. That is specifically what happened when two bettors split a ₱73M Mega Lotto jackpot, and each walked away with less than half the headline figure. More coverage, smaller actual payout.
None of these tactics change C(42,6) = 5,245,786. The combination formula is fixed.
What is a ₱25 lotto ticket really worth?
Based on PCSO prize structures and publicly available draw data, roughly 50-55% of total ticket sales go into the prize pool. For a ₱25 ticket, the real expected value works out to approximately ₱12-14. PCSO includes a 20% Documentary Stamp Tax (DST) in every ticket price from the start.
| Where your ₱25 goes | Estimate |
|---|---|
| Prize pool (your expected return) | ~₱12-14 |
| PCSO operations + charity | ~₱6-8 |
| Documentary Stamp Tax (20% DST) | ~₱5 |
Source: Philippine News Agency; PCSO ticket price update
You pay ₱25 for roughly ₱12 worth of prize money, and that is before your 1-in-5.2M odds apply. I ran this calculation once out of curiosity. It felt like a cold slap.
When does the expected value improve?
When the jackpot rolls over repeatedly, the prize pool grows beyond its usual level. A ₱500M jackpot improves the expected value considerably compared to a ₱10M jackpot for the same ₱25 ticket. Winnings above ₱10,000 also get taxed at 20%, which reduces your actual take-home. The math is less brutal during massive rollovers – but it stays negative.
So should you still play?
C(42,6) = 5,245,786. No pattern or prayer changes it.
A ₱25 ticket buys you a genuine night of “what if” – and that is worth something, as long as you call it entertainment and not a plan. Play when the jackpot is already massive (₱50M+), spend only what you would drop on beer and pulutan in one night, and never count a ticket as a financial move.
