Grand Lotto 6/55 Defining What's Hot And Cold

There's no absolute rule that determines what's hot or cold from a lottery. It's up to you to set your own rules.

Based on my observations, hot and cold numbers are not permanent. What's hot today may be cold after 9 draws. The all-time hot numbers, i.e. most frequently winning numbers of all time, do not usually win together. For example, the all-time hot numbers 26, 40, 55, 29, 34 and 18 have not made it to the jackpot; not even the 2nd prize. They have won 4 numbers twice though, and 3 numbers nine times. The reason for that is that, perhaps, these numbers do not belong to the same set of balls. Nevertheless, it's a good combination and winning the jackpot is not impossible. It's just a matter of timing – i.e. when all statistical factors are favorable.

Four Seasons: Defining the hot and cold zones

Here's how I categorized the last 21 lotto draws. I used the 4 seasons: summer, spring, autumn, and winter to define the hot and cold zones and those in between. The summer period refers to most recent draws while the winter refers to the earlier draws.
  • Summer. The hot season. This is the zone or period where you find the hot numbers. It refers to the last 6 draws. 
  • Spring. The numbers here are neither hot nor cold but they spring up to win from time to time. It refers to the next 3 draws prior to the last 6 draws. All in all, the summer period plus the spring period equals (the last) 9 draws. 
  • Autumn. This is the season when numbers turn cold. Count the next 6 draws earlier than the last nine draws, that's your autumn. 
  • Winter. This is the season when numbers turn colder and tend to hibernate. Prior to the autumn period, count another 6 draws and that's your winter. All in all, the full season covers the last 21 draws. 
Why 21 draws? The 21-draw period refers to the common time or period a cold number reaches its peak. When a cold number reaches its peak, it wins again. On record, the number 27 had turned cold and hibernated for a period of 67 draws. A hibernation period of greater than 21 draws is possible but rarely happens. A hibernation period covering 21 draws is what I consider the threshold. If a number has not won within this period, most likely it hibernates for a longer period. On the contrary, the numbers that stay in this period may win over and over again.

Some statistical tips

  • There's a 98% chance that 1 to 5 of the jackpot numbers may come from the summer season. 
  • There's a 97% chance that zero to 2 of the jackpot numbers may come from the spring season. 
  • There's a 98% chance that zero to 3 of the jackpot numbers may come from the autumn season. 
  • There's a 99% chance that zero to 2 of the jackpot numbers may come from the winter season. 
To interpret the data above, take for example the winter season. There's a 99% chance that zero to 2 of the jackpot numbers may come from the winter season. That means that there's only 1% chance that 3 numbers or more may come from it. In other words, 3 cold* numbers do not usually win all at the same time from this season. Either only 1 cold number, 2 at most, (from the winter season) or none at all. (*A cold number from the winter season is a number that has not won for more than 15 draws. This may tend to hibernate after 21 draws of not winning.)

In A Nutshell

To define the hot and cold seasons of a recent lotto period, get the last 21 draws. Beginning from the latest one, divide the draws into 4 periods as follows: 6, 3, 6, 6 where each period covers 6 draws except for the 2nd period, which covers only 3 draws. I name the 4 periods in this order: summer, spring, autumn, winter.

What's the significance of this? You can establish high probability factors that may affect a winning number. For example, how many cold numbers should I play or how many hot numbers. What about the numbers that are neither hot nor cold? How many of them should I play?

In the future, I will tell you the exact statistics that determines how many winning numbers may come from each season.
