    2. - -
  2. - Get an overview of puzzles, - and start working on something. - The list of open puzzles changes over time, - you need to reload the page to get the current version! -
    3. - -
  3. - Check the scoreboard - in another tab, - to see how your team is doing. -

Register Your Team

About scoring

- -
-

How we compute scores

- -

- The contest is made up of multiple categories. - Each category is worth one point toward the total score; - your team's score in a category is the fraction of the total points unlocked so far in that category. -

- -

- The team that has 30% of the points - in each of five categories has 1.5 points, whereas the team that - has 80% of the points in only one category has 0.8 points. It is - typically better to have a few points in many categories, than - many points in a few categories. -

- -

- When points are unlocked in a category, - every other team's score in that category goes down until they too score that point. - Unlike previous years, however, - unlocking points is the only way to reduce another team's score. -

- -

- There are two main ways to make points: puzzles - and tokens. Your contest may have other ways to make - points: these will either be automatic, or explained elsewhere. -

-
- - -
-

Puzzles

-

- Many of the categories are in the form of - multiple puzzles: for each puzzle presented, a - case-sensitive answer must be found to receive the amount of - points that puzzle is worth. Any team may answer any puzzle - question at any time. A new puzzle is revealed when a team - correctly answers the highest-valued puzzle in that category. -

-
- - -
-

Tokens

-

- Tokens are strings redeemable once for points. They take on - two forms: a single or multipoint token. A single point - token for the "example" category might look like this: -

- - 
example:xylep-radar-nanox
- -

- A 42 point - token for the "example" category might look like this: -

- - 
example:42:xihyp-ropar-nanix
- -

- Tokens are typically associated with "live" categories, such as a - network-based service or a treasure hunt. Tokens can be submitted - with the form on the welcome page, or you - can write your own script to automate token submission. -

- -

- Some tokens change periodically, typically once a minute. If you - find a token, it's worth looking in the same place again later to - see if the token changes. -

-
- - -
-

About time

-

- Many Capture The Flag contests attempt to reward teams who answer - quickly, by adding a "quick answer" bonus or by decaying point - values over time. Our contest doesn't work this way. -

-

- We want to focus on rewarding technical proficiency, allowing - skilled contestants to prove their worth independent of their - ability to hit F5 quickly. It is our hope that by providing - enough things to work on, quick-moving teams will emerge with more - points by solving lots of puzzles, while novice teams get a solid - benchmark against which to judge their technical skill level: you - don't have to make allowances for reaction time in comparing - scores. In addition, when the game infrastructure goes down—which - seems to happen a lot in anybody's CTF—there's no losing points - while the organizers struggle to get things back up. -
