Heads or tails, decided by secure randomness.
This page opens the random picker with Number selected, so the Smallest, Largest and How many boxes are ready to fill. Each number is drawn with secure randomness from the range you set, and the last ten results stay on screen for this visit.
Turn on No repeats when every number in a draw must be different. With it off, a number can come up again in the same draw. For names rather than numbers, use the random picker.
How it works
- Choose names, a number, a coin or dice.
- Enter your names or range, and how many you need.
- Press the button. The last ten results stay on screen for this visit.
Questions
What does No repeats do?
When it is ticked, no number appears twice in one draw, so asking for five numbers gives five different ones from your range. Leave it off when repeats are fine.
Can I use it to choose a row in a spreadsheet?
Yes, if the rows are numbered. Set the smallest and largest row numbers and how many rows you want, then tick No repeats so no row is picked twice.
Is the random picker truly random?
It uses crypto.getRandomValues, the browser’s cryptographic random source, and discards values that would tilt the result. Every name, number and face has the same chance.
Does it keep my list of names?
No. The list stays in the box on this page. Nothing is uploaded, and the history is cleared when you close or reload the page.
Can the same name win twice?
Not in one draw. Winners are different names from your list. Tick “Remove winners from the list” to take them out before the next draw.
Are coin flips fair?
Each flip is an independent 50/50 choice made with secure randomness. The tally counts the flips made in this visit.
