The Skull's Scoring System 🏆

Here's how the scoring works: each challenge has a base score, and your final score is calculated by adding a rank bonus and a brevity bonus to that base score:

Final score = base score + rank bonus + brevity bonus

Base Scores

The base scores are:

ChallengeBase scoreBytes **
Capture The Flag4500-
Mind Control950039
The Virus *7500130
Medulla Oblongata *750089

* These are the bonus challenges
** The Bytes value is used for the brevity bonus and will be explained below.

Rank Bonuses

Your rank bonus will depend on how many people have already solved that particular challenge:

Brevity Bonuses

Your brevity bonus works as follows: if the size of your solution (in bytes) is smaller than the value in the Bytes column above, then you get 100 additional points for each byte you saved. But if your solution is larger than that value, then you lose 50 points for each extra byte.

An Example

Suppose you were the 2nd person to solve the Mind Control challenge, and your solution was 40 bytes long. In this case, your score would be calculated as follows:

  • Base score: 9500
  • Rank bonus: 400
  • Brevity bonus: -50
  • Total score: 9850


You can submit an improved solution at any time. If you do, a second score will be calculated based on the number of solutions that have been submitted at that point in time. Your actual score will only change if this new score is higher than your previous one.
