Draw names or numbers round after round

Choose Names or Numbers, enter the pool, set how many winners each round should have, and press Generate. Every draw is added to a local history with its round number and time. Each entry can be picked once per round; later rounds can pick it again.

  1. Choose the Names or Numbers mode.
  2. Enter one name per line, or whole numbers separated by spaces, commas, semicolons, or lines.
  3. Choose the number of winners for the round.
  4. Press Generate and the round is saved automatically.
  5. Reload the page later and the history is still here.

Quick options without typing

Use Quick draw to get a random number, flip a coin, roll dice, draw playing cards, pick six lottery numbers, or choose Yes or No. Choose from the menus and press Draw; every result is added to the same local history.

Draw a sequence of numbers

Numbers such as 01, 02, 03, 04 or 1 2 3 4 are accepted. Leading zeros are preserved, and repeated numbers count once. The same number can be drawn again in a later round.

History stays on this device

常见问题

Where is the draw history stored?

In your browser's local storage. It is not sent to the server.

Can one item win twice in the same round?

No. Each line is removed from the pool after it is drawn. The same item can be drawn again in a later round.

Can I draw more winners than items?

No. The number of winners per round cannot exceed the number of lines.

Does clearing history reset the round number?

Yes. After clearing, the next draw starts again at round 1.

Can I draw from a list of numbers?

Yes. Switch to Numbers and enter whole numbers separated by spaces, commas, semicolons, or new lines. Each number is drawn at most once per round.

Can I use it without entering a list?

Yes. Quick draw flips coins, rolls dice, draws cards, picks lottery numbers, chooses Yes or No, and generates random numbers from a selectable range. No typing is needed.
