Quick answer: It makes no difference: always playing the same numbers or changing them every draw does not change your odds, because each draw is independent and every combination has the same chance of coming up. In La Primitiva, for example, the odds of matching 6 numbers are always 1 in 13,983,816. The choice is purely a matter of preference.

Many lottery players have a preferred strategy when choosing their numbers. Some always play the same combination, while others select new numbers for every draw.
Mathematically, every valid combination has exactly the same chance of winning. Whether you keep the same numbers or change them regularly makes no difference to the odds.
There is no scientific evidence that any number is luckier than another. Every draw starts with the same probabilities.
It is neither better nor worse. Your odds of winning are exactly the same whether you repeat your combination or change it every draw.
No. Draws are independent and have no memory: a number that has not appeared for a while has the same probability as any other.
Mainly for convenience and to avoid the risk of it coming up the one week they do not play it. Many use dates or numbers with personal meaning.
You can play your combination regularly at a lottery office or through an online service like Serviloto, so you do not depend on remembering each week.
No. The ideas of hot or cold numbers have no mathematical basis. The only difference is that very popular combinations, such as dates, tend to split the prize among more winners.
Lottery games are based on chance. No strategy can guarantee success, so it is important to play responsibly.
Playing the same numbers or changing them does not affect your chances of winning. The best approach is simply the one you enjoy most.
