    Frequently asked questions

    What is a weight?

    A weight is a probability ratio. If A has weight 2 and B has weight 1, A is twice as likely as B.

    What happens with weight 0?

    Items with weight 0 stay in your list but will never be selected. Enable the advanced option if you want to display them in the probability table.

    Can I reproduce the same result?

    Yes. Turn on the seed option and keep the same seed. You can also copy the URL to share the same setup.

    What if the share URL is too long?

    If your item list is long, the URL can become long too. Use Export JSON for a portable alternative.
