This directory contains the static web site that is served at http://hashunt.josh.com.
It is called docs because it is hosted on GitHub pages and that is apparently the only folder name you can use.
The actual game made out of html, css, and js all in one file because that is the way I like it.
You can call this with two optional params...
ws gives a full URL to an alternate websocket server.
nBits gives a forced value for nBits. This value will not be overwritten by updates from the websocket server. A value of 0x20010000 needs only two hashes and is winnable in a few minutes, especially if you hold down the mouse and slide or use km.
These are intended for testing wins, but note that any invalid win will be rejected by bitcoin-core so don't bother trying to cheat.
