Instructions

Here are some hints on how to use this website.

  1. To get started go to Active Contests; you can then enter any contest for which the window has started.
  2. You do not need to register a user account to participate. When you enter a contest, you will be asked for just a name and email (no password), and once you submit this information the timer will start automatically.
  3. When you enter a contest, you will be given a special link to a page where you can enter answers. We use this link in lieu of an account/password system, so be careful not to lose it.
  4. The format of contests may vary; see each contest for more information. In general, each contest will have a time limit and a set of problems with fixed weights.
