Lotto Number Picker

Picks number sets with exclusions and fixed numbers, and checks a saved set against past results.

Picking six numbers from 45 is a decision with no correct answer, which is exactly why people want a tool for it. This generates sets with numbers you want kept and numbers you want excluded, and checks a saved set against past draws.

The number of ways to pick 6 out of 45

  • The odds of 1등 are 1 in 8,145,060. They are the same whichever combination you choose.
  • Each draw is independent. A number that has not come up for a while is not due.
  • Choosing by which numbers have come up often or rarely has no statistical basis.
  • This tool picks numbers. It does not improve your chances.
The numbers come from the browser’s cryptographic random source. Math.random() * 45 is very slightly biased toward the low numbers, so the remainder range is rejected and the draw repeated. It makes no difference to your chances of winning — but saying the draw is uniform means it has to actually be uniform.

How to use it

  1. Set the fixed and excluded numbers

    Anything you always play stays in; anything you want to avoid comes out. The rest of each set is drawn from what remains.

  2. Generate as many sets as you need

    Each set is drawn independently with the browser’s random source, so two sets are not related to each other.

  3. Check a set against past results

    Useful for finding out how a set would have done. It is a record of what happened, not a prediction of what will.

Common questions

Do some combinations win more often?

No. Each draw is independent and every combination has the same 1-in-8,145,060 chance, whatever came out last week. Any pattern in past results is what randomness looks like, not a signal.

Should I avoid numbers that came out recently?

It makes no difference to your chance of winning. The one thing it can change is the payout — a prize is shared among winners, so a set nobody else picked pays more if it wins. That is an argument about other players, not about the draw.

Is this connected to the official draw?

No. It generates and compares locally, and it sells nothing. Buying a ticket is done through the official channels, and this is not one of them.
