Dev Server

Pick a seed:

{seed}: a special seed I made just for you!
random: will use a different seed every time you load a page (could be useful for debugging)
You can also hack your own seed into the URL, if you want to.

Puzzles can be generated from Python code: these puzzles can use a random number generator if they want. The seed is used to create these random numbers.

We like to make a new seed for every contest, and re-use that seed whenever we regenerate a category during an event (say to fix a bug). By using the same seed, we make sure that all the dynamically-generated puzzles have the same values in any new packages we build.
