How it is calculated
The algorithm walks the list from the end and swaps the current item with a random earlier one. Every order is equally likely.
Fisher–Yates shuffle
Where the numbers come from
- List
Example
A list of several tasks comes out in a new order each time.
Questions
Repeated lines?
If you typed two identical lines yourself, both remain.
How do I get a different order?
Edit the list and the order is worked out again. The Share link remembers the order you have. Reloading the page does not shuffle it.
Do I need one line, not the whole list?
There is a random pick for that.
