*[Q] I’ve been analyzing all my past lottery results over the years and whilst I know these things are supposed to be random, there is a pattern.*

*Some numbers have definitely been drawn more often than others, and some have definitely appeared in the jackpot combination more than others. Should I play those numbers?*

[A] You’re absolutely right.

Do you remember rolling a dice at school and charting the results? You tallied up each number as it was rolled, and then drew a little bar graph of the results. And the graph made pretty much a straight line proving that all the numbers had the same chance of being rolled.

Or did it?

Actually your graph was pretty wonky – oh yes it was! But don’t take offense, I’m sure you drew yours just as well as I did ;-).

But all of our graphs were actually pretty wonky, and wonky in different ways too. If we took all our results together and drew another graph covering all of them, then we’d have one that was smoother. But still not perfectly straight.

We all get caught up in what we think we learned about ‘averages’.

But the fact is if you take any set of past results from any lottery for any period in time, you will find the same thing. Some results appear more or less often than others – a wonky graph. And that’s because this is exactly the sort of result that is entirely normal for a random process. If it were not possible for this to happen then the results would not be random (huh?, maybe read that sentence again 😉 ).

With randomness if you actually repeat the ‘test’ enough times then every possible set of results would happen. Not just every result, but every different wonky graph for each set of results you pull out. So everything from never winning a single thing on the lottery, to hitting the jackpot every single draw for your whole life!

This is how random works. Just because the current state of play is ‘less likely than the true average’ does not mean there is anything unusual going on.

The weak point in the chain here is actually our brains – they love to see patterns in randomness. That’s the nature of our brains, we just can’t help trying to make a nice comfortable order out of things. And when it happens to be numbers we’re trying to make order of we’re even worse than ever!

So the bottom line of all this is whether or not the number patterns we’re seeing really mean anything. And that’s not as easy to determine as you might think. Because, as we’ve covered, random does weird things anyway.

Larry// Aug 28, 2013 at 5:25 pmI was just reading this on patterns. I’ve developed some code utilizing Excel and the past drawing numbers. I play mainly Texas Two Step and Powerball. I win Many small pots at least 6 times a month includIng $7, $100 and $10,000 so…, IMHO they paint a pretty picture.

LG// Aug 28, 2013 at 6:20 pmHey Larry

But it doesn’t paint the whole picture though.

Last year a woman bought her first ever lottery ticket and won $1m on Powerball. If she said she used a spreadsheet to pick her numbers, would that mean she had a working system..?

I know that’s an extreme example. But the point is, you can’t say your spreadsheet makes any difference unless you prove there is some statistical significance to the results.

We’re easily drawn into placing extra significance on wins, but without the full picture I can only congratulate you on your luck – not your spreadsheet 🙂

For fun, why not also play the same number of quick picks alongside your spreadsheet based selections, and see how they compare? You don’t have to buy them, you can always just play them on paper.

Jl1358// Jul 5, 2017 at 11:59 amSimilar to Larry’s original post what about strategies that focus on small wins and not the jackpot. In IL the local game plays twice a day by selecting 5/45. Selecting 5 of the 5 winning numbers of course gets you the jackpot. But getting 3 out of 5 gets you $15. if you look at this from a roi perspective say we could spend $10 to make $15. Sounds like a great return. This means we’d have ten chances to successfully pick 3 winning numbers and still get a 50% return. Has anyone tried to develop strategies to grind out small winnings consistently overtime?

LG// Jul 5, 2017 at 6:27 pmIf you could guarantee turning $10 into $15, then you’d spend as many $10 as you had every single time. But I get what you mean 🙂

It sounds like you’re describing wheeling systems. A well designed wheel will be optimised for certain conditional win guarantees. I recommend Bluskov’s book here for wheeling systems. Just forget anything you may have been told about wheeling – it’s typically vastly overhyped, but it is still useful.

Pascal// Apr 27, 2014 at 9:44 amI believe in past result for a clue simply because past result can give you a particular pattern to stick to. All syndicates operators must build their system on a pattern that has won a jackpot before from the past results. The same theory is used by Wall Street gurus ie charts, graphs etc. I have a clue for EuroMillions but we will need at least 100 people to win the jackpot every month. Yes I mean it.

LG// Apr 27, 2014 at 6:33 pmHi Pascal

It would be nice if we could predict lottery numbers from past results, but nobody has ever been able to prove it (despite all the people selling systems that claim they can).

But good luck anyway 🙂

Danilo// Apr 14, 2015 at 7:33 pmI understand your point that there might not be a significant pattern in balls being drawn as they all are equal. However, please remember that balls are labeled and arranged in x ways every time due to ball sets. In addition, at least in FL Fantasy 5, the chamber on the machine blows each ball at 400 cu/m and balls weigh 2 grams. With this setup in mind, don’t you think that a pattern is definitely possible? As speed, weight and ball sets are constant. The only thing that is manipulated and we all know is the prior “testing” to a game being drawn. I’ve been tracking this specific game for ten months now and have found that at least twice or three times a month a pattern of three out of five numbers will repeat itself. The goal here is to know when that specific pattern will play again and play all possible combinations for the two missing numbers which in this case is about 600 numbers. I dont spend my money every day but I do analyze this game on a daily basis. Oh and let’s not forget that d/t=v and so does v/t=d and so on. In short, for the Fantasy Five I do see a pattern that I am working on figuring out.

Danilo// Apr 14, 2015 at 7:45 pmIf the world revolves around the sun every 365 days and this pattern still continues. Then in my opinion, I have no doubt that lottery games have the same laws applied. For instance, if you look back at games played in the 1990’s when the Fantasy 5 was 5/26, amazingly you will find that many times winning numbers repeated. Then, ever since the game odds were increased I still have not seen five numbers repeat itself. But have surely seen 3 out 5 repeat itself very often.

LG// Apr 15, 2015 at 12:48 amBut the earth doesn’t have 35 other planets all colliding into it multiple times per second. So it’s orbit is fairly reliable 🙂

Steve// Mar 17, 2016 at 12:02 amDo you know what I get the whole maths thing and can’t argue with it logically so I won’t try. I’m not sure though I believe it is truly random in fact I don’t think anything is, random that is. There has to be something influencing things, what, I don’t know. I haven’t checked this so Here’s a random comment to sit directly opposed to your NOT random lottery! The Number 13 I bet that’s languishing near the bottom of the list in the most drawn number stats in the majority of lotteries around the world. I hope to god I’m right as this goes against everything my normally logical brain is telling me and deserve all the slating that I’m going to get. If I’m wrong I’ll return with a sensible answer.

LG// Mar 19, 2016 at 7:21 pmThere’s no reason why no. 13 would be

drawnany less than anything else – after all, what could possibly influence that? (If you swapped the numbers on ball 13 and ball 7 would that then change the effect..?)But maybe you meant picked by players less often? Although if you’re thinking ‘unlucky’ number therefore it gets picked less, you also have to consider which countries lottery you’re playing because the concept of lucky numbers varies greatly depending on your culture – in Russia odd numbers are considered lucky, in Italy 13 is a lucky number. In China not only is 13 not recognised as unlucky, but 7 is also seen as unlucky!

There are also a lot of people who pick 13 because it is considered unlucky by many in the belief that therefore nobody plays it 🙂

Aristillus// Jan 12, 2017 at 7:08 amIt is important to understand that no one, and I really do mean ‘no one’ can design or come up with a system that can predict what numbers will be drawn, even factors of probability cannot be used to draw particular conclusions as to which numbers will be drawn.

Every new draw holds the same probability value for each number. The only issue is that the probability of drawing a particular number increases with each drawn number.

So for instance, you have six numbers picked and paid for towards the next lottery draw. Prior to the first number being drawn by the machine in a lottery that draws 6 main numbers and a 7th ball as a ‘bonus ball’, all numbers have the same probability value. So if the lottery is 6 from 49, the probability value for each number that could be drawn first is, remarkably enough, 1 in 49.

When the first of the 7 numbers is drawn, the probability value for the next number becomes 1 in 48, and for the third drawn number it is 1 in 47, whilst the fourth is 1 in 46, the 5th is 1 in 45, the 6th is 1 in 44, and finally the 7th ball (as bonus ball) is 1 in 43. You cannot summarise a probability value that can score a target number to be draw so that one would pick it. Patterns of probability only emerge after the event, and with lotteries, they cannot and should not be used to try and identify numbers that might be drawn in the next round. Past results are not affective on present or next round of number drawings.

With each round of new drawings, all probabilities reset to null values. Play the lottery for fun only, and never expect to win, only expect someone to win, and if you are very lucky, it might be you, but don’t count on it.

LG// Jan 12, 2017 at 8:31 pmThere is some wiggle room in this (the post is 9 years old!) – this is all true assuming a perfect random draw. Whether it is possible to operate a perfect random draw, and degrees of randomness is a whole other debate though.

Joe// Nov 1, 2017 at 4:04 pmPast numbers are useful. You can check to see if you happen to have chosen a previous number set. What are the odds of the exact same number being drawn twice.

LG// Nov 1, 2017 at 5:43 pmIn pure maths terms – exactly the same chance as any other combination being drawn.

Just like when you roll a dice. If you roll a 6, what are the odds of getting a 6 again? Still 1 in 6 isn’t it 🙂

Joe// Dec 29, 2017 at 9:39 pmHey LG,

I came across your blog, by looking to verify my theory that lotto is random and one cannot look for patterns. It’s a really good blog.

Then I have read your recent comment:

“There is some wiggle room in this (the post is 9 years old!) – this is all true assuming a perfect random draw. Whether it is possible to operate a perfect random draw, and degrees of randomness is a whole other debate though.”

and it threw me a bit off-balance. So, what are you saying now, that after 9 years of research – you came with the idea that the lotto is not a 100% random? Previously, you talk about the machines with tight tolerances, the temperature in the studio, the passing truck vibration, etc, etc, which as far as I understood – just add more noise to the already random drawing of the balls.

Could you please, elaborate on your comment?

LG// Dec 29, 2017 at 11:49 pmHey Joe

Sure – simply that creating a mechanical machine that is ‘100% guaranteed random’ is pretty much impossible. Mainly because even proving it is impossible! How many draws would you have to run to prove beyond doubt that it was perfectly random (and how long would that take… and could running that many draws introduce a bias from wear and tear… etc etc).

But don’t think I’m taking a u-turn here, I’m really not 🙂

By wiggle room I just mean that the lottery company consider their machines ‘random enough’. It’s theoretically possible that there is some mechanical bias there. But anyone who claims to have PROVEN it is talking nonsense, because 1. it’s never going to be big enough to be proven, and 2. you’re never going to have enough data to prove it anyway.

Julie// Jan 5, 2018 at 11:03 pmThen how can Richard Lustig and others claim to have unlocked the Lottery Code?

LG// Jan 6, 2018 at 12:46 amRichard has won a lot less than you think (details are here). For example, most of us wouldn’t consider a prize worth $3,594 to be a jackpot or major prize… yet he counts it as one of his ‘7’. He also isn’t claiming any wins since 2010. So the reality is a vague shadow of the hype 🙂
