Swiss pairing

Pairs the next round by score without repeating a meeting, and gives an odd field a bye.

It runs entirely in this browser tab: nothing you type is uploaded, and every draw comes from a seed the result prints.

Settings

Show the standings
The running scores beside the pairings, which is what gets pinned to the wall.
Rounds already played
Only recorded on the result; the pairing itself follows from who has played whom. A number from 0 to 30.

How to use it

  1. Paste your text into the box above, or open a file.
  2. Adjust the settings beside it until the result is what you wanted.
  3. Copy the result, or save it as a file. The result updates as you type.

Questions

Why does everything have a seed?
So that a roll can be checked. A draw here is a function of its seed: the same word gives the same result to you, to the person you send the link to, and to the desktop build. Leave it empty and a fresh seed is drawn and shown, so you can pin a roll after the fact.
Can I use this to deal cards for money?
No. The generator is reproducible on purpose and invertible from a single output, which is what makes it useful here and useless for that. It is not a cryptographic source of chance and the result says so.
Why is there no word list in the word finder?
Because a usable one is larger than this whole application, and a small one is worse than none: it says “not a word” about words. The list comes from you, and the result says how many words it searched so a search that found nothing is visibly a short list.
Does the chess reader have an engine?
No: no evaluation, no best move, no opening book. What it does is replay a game on a real board, which is a fact about the rules rather than an opinion about the moves — and it stops at a move that will not play rather than reading past it.
