After working in the gambling industry for over a decade, Oliver spotted an opportunity to setup a resource for lottery bettors. CompareTheLotto.com was founded in 2014, with Number49s.co.za following shortly after. The aim is to find the best odds, offers and information for lottery bettors in South Africa.

If you've spent any time on lottery betting sites, you've almost certainly come across the terms hot numbers and cold numbers. They appear on results pages, betting tools, and tip guides — but what do they actually mean, and should they influence how you bet on the UK 49's?

This guide explains exactly what hot and cold numbers are, how they are calculated for the 49's, and how to use them sensibly as part of your number selection.

What Are Hot Numbers?

Hot numbers are the balls that have been drawn most frequently over a recent set of results. In the context of the 49's, a hot number is simply one that has appeared more often than others across the last batch of draws — whether that's the last 10, 20, or 50 results depending on the tool you're using.

For example, if the number 7 has come up 9 times in the last 20 draws, while most numbers appeared 3 or 4 times, then 7 would be classified as a hot number.

What Are Cold Numbers?

Cold numbers are the opposite: the balls that have appeared least frequently over the same period. A cold number is one that seems overdue — it hasn't come up much recently, even though in theory every ball has an equal chance of being drawn each time.

Some bettors are drawn to cold numbers on the basis that they're "due" to appear. This is worth examining more carefully.

How Are They Calculated for the 49's?

The 49's draws six main balls and one booster ball from a pool of 49, four times a day across the Brunch Time (13:49), Lunchtime (14:49), Drive Time (18:49), and Teatime (19:49) draws. Over time, the frequency of each ball is tracked and ranked.

On this site, our Hot Picks and Hot & Cold Balls pages pull from recent draw data and rank each ball by how often it has appeared. The top four are labelled hot, the bottom four cold.

It's a simple but transparent method — you can see which numbers are trending upward in frequency and which have gone quiet.

The Important Caveat: Each Draw Is Independent

Before going further, it's worth being direct about something: each 49's draw is a completely independent random event. A ball that has appeared 10 times in the last 20 draws has exactly the same probability of appearing in the next draw as a ball that hasn't come up at all.

The idea that a cold number is "due" is known as the gambler's fallacy — the mistaken belief that past results influence future ones in a random system. They don't. The draw machine has no memory.

So why look at hot and cold numbers at all?

Why Bettors Still Use Them

Despite the statistical reality, hot and cold numbers remain popular for a few practical reasons:

• They provide structure. Choosing numbers from 1 to 49 is genuinely difficult when every number seems equally valid. Hot and cold data gives you a starting point and narrows the field.
• They reflect short-term patterns. While random in theory, draw results sometimes cluster in the short term. Hot numbers capture which balls have been active recently.
• They're quick to use. Rather than analysing dozens of past results yourself, hot and cold tools do the counting for you.
• They're no worse than any other method. Since no system can predict random outcomes, using hot numbers is as valid as birthdays, lucky numbers, or any other selection method — just with a data-driven framing.

Hot Numbers vs. Cold Numbers: Which Should You Use?

There are two schools of thought here:

Follow the hot numbers: Back the balls that are appearing frequently. The reasoning is that short-term clusters can persist for a while, and you're aligning with what's been happening.

Back the cold numbers: Choose the balls that haven't appeared recently, on the basis that the distribution should even out over time. This is the "due" argument — though as noted above, it doesn't hold statistically.

Neither approach is objectively better. The most honest position is that both hot and cold selections give you a structured way to pick numbers without any genuine predictive advantage over random selection.

How to Use Hot Picks on This Site

Our Hot Picks page shows suggested numbers for all four daily 49's draws across 1-ball, 2-ball, 3-ball, and 4-ball bet types. The picks are updated daily and based on the most recently drawn balls.

Here's a simple way to use them:

1. Visit the Hot Picks page before the draw you want to bet on.
2. Choose the bet type that suits your budget — a 1-ball bet is the simplest entry point.
3. Take the suggested hot number(s) as a starting point, then adjust to your preference.
4. Place your bet at one of the bookmakers listed on our odds page.

You can also cross-reference with the Hot & Cold Balls page, which shows the full frequency ranking for all 49 balls — useful if you want to go deeper into the data.

A Sensible Approach to Betting on 49's

Hot and cold numbers are a useful tool when treated as what they are: a data-driven starting point, not a prediction system. Use them to add some structure to your selection, but go in with clear eyes about the odds and the random nature of the draws.

Set a budget before you bet, stick to it, and treat any win as a bonus rather than an expectation. The 49's is an entertaining game with four draws a day — that's part of its appeal in South Africa.
