User score settings resources

User score is a gamification feature which, when enabled, awards users with points for performing certain actions. Upon reaching a certain number of points, users are promoted to a higher level.

User score calculation

The minimal score for reaching a level is calculated with the formula below, which reflects quadratic growth. The coefficient c is set to 100.

There are infinite levels. The first level is level 1, with a minimal score of 0.

With a coefficient of 100 (the default value) the first five thresholds are distributed like this:

Level 1:0 points
Level 2:100 points
Level 3:300 points
Level 4:600 points
Level 5:1000 points

Points are awarded for the following actions:

  • Publishing a question: 300 points
  • Publishing a solution to another user's question: 500 points
  • Converting a Comment to another user's question to a solution: 500 points
  • Being recommended as an expert for a question: 50 points
  • Writing a new Comment: 20 points
  • Receiving an upvote for a comment: 10 points
  • Viewing a Question for the first time: 5 points
  • Receiving a rating for a solution they have published
    • Rating 1: 0 points
    • Rating 2: 0 points
    • Rating 3: 30 points
    • Rating 4: 40 points
    • Rating 5: 50 points

Points received for actions that are later on deleted (e.g. question, solution, change of rating) are removed again.
A user can never level down. If a uses loses more points than he has in the current level, then his score will be set to the minimal number of points in the current level.

A user's score point are returned by the API and if the gamification is enabled in settings. If not enabled, the user fields score\_points and score\_level will contain the value null.

Important: Changing the start time will not change user scores aggregated in the past.

Get user score

GET /settings/user-score

{
    "enabled": false,
