LeetCode Contest
Contest Rating & Badge
The contest badge is calculated based on the contest rating.
For LeetCoders with rating >=1600, If you are in the top 5% of the contest rating, you’ll get the “Guardian” badge.
If you are in the top 25% of the contest rating, you’ll get the “Knight” badge.
| Level | Proportion | Badge | Rating | |
|---|---|---|---|---|
| LV3 | 5\% | Guardian | ≥2123.78 |
|
| LV2 | 20\% | Knight | ≥1854.07 |

| LV1 | 75\% | - | - | - |
For top 10 users (excluding LCCN users), your LeetCode ID will be colored orange on the ranking board. You'll also have the honor with you when you post/comment under discuss.
The global ranking includes LCCN users, so the cutoffs below follow the Guardian / Knight contest badges actually shown on leetcode.com (not a raw 5% / 25% split of the mixed global list).
