Badges awarded after a site feature has been used.

Badges awarded for consecutive days or weeks of continual activity in an area. For example, a daily tactics streak of 10 is achieved by solving tactical problems for 10 consecutive days in a row. A weekly tactics streak of 6 would be achieved by solving at least once a week for 6 weeks. Activity streaks are tracked for tactics, endgames, guess the move, and online play. There is also a global activity streak tracker which is a daily streak maintained by being active in any activity on the site. For example if you solve tactics problems one day, and play games the next day, that would be an activity streak of 2. The current global activity streak is shown at the top of most pages on the site, and a tick on the streak icon indicates you have achieved your daily activity for today.

Badges awarded based on the number of comment likes received from other users.

Badges awarded for sequences of successful outcomes. For example when solving tactics, 10 correct in a row would be a success sequence of 10. Similarly, 10 won online games in a row would also be a success sequence of 10. Success sequences are tracked for sub types of an activity, so you if you get 5 blitz problems correct, then 1 standard problem wrong, then 5 more blitz problems correct, that is still a success sequence of 10 in blitz problems. The same applies for different rating types in online play.

Successes in period tracks the number of successes for periods of an hour, day, week, month or year. For example if you win 20 games in a week that is a weekly success number of 20.

Total time spent tracks achievements for the total time spent on each activity area. Outliers are truncated when calculating these values to avoid accounting for time spent while a CT page is open but not being actively used.

Badges for upsets are awarded for success against an opponent or training problem well above your own rating.

Your personal best for each activity type is tracked and badges are awarded for achieving a new personal best.
