"Hot" numbers are the ones drawn most often in recent results; "cold" numbers have appeared least; "overdue" numbers have not been drawn for the longest time.
Do they predict anything?
No. Lottery machines have no memory, so each draw is independent. Over a short window some numbers will always look hot or cold simply by chance.
Why people still enjoy them
Statistics make a game more interesting to follow, and choosing a strategy — hot, cold or pure random — is part of the fun. Our Statistics page shows the numbers for every game with results, and the generator can favour hot or cold numbers if you like.
