All content on CodinGame is published under the following license: License CC BY-SA 2.0
A contribution has 3 different states:
- Private: a draft that can be shared with friends with the link.
- WIP: as Work In Progress. Visible by everyone for feedback and suggestions but not yet ready to be approved and published. WIP contributions cannot be approved. Unless the author changes its state, a WIP contribution goes back to a private state after 30 days.
- Ready: visible by everyone and ready for approval. If a ready contribution is not approved/rejected after 30 days, it goes back to a private state.
To submit a classic puzzle or CoC puzzle as WIP or Ready, the author must provide a solution to the puzzle, in any language.
It's highly recommended:
- to solve enough puzzles before trying to create your own
- to publish a contribution as "WIP" first to get feedback from the community.

When creating a coding game, we suggest you follow these best practices in order to improve both its performance and the players' experience.
- If options for a player are limited, they should be sent in input (ex: Wondev Woman)
- The player's id should be 0.
- The player's input should be sent first in loops.
- Any non-explicit variable should be explained with a comment.
- The stub should not change between leagues.
- The generated stub should not contain more than 45 lines in Java.
- The number of variables per loop should not exceed 10.
- There should be a maximum of 2 loops.
- The game should be turn-based. Only perform checks (collision, presence, etc.) at the end of a turn.
- The total entities should not exceed 200.
- The maximum number of rounds should not exceed 250.
- The maximum alloted time per player should not exceed 25 seconds.
- It's possible to write a working AI in a few minutes.
- If several leagues exist: boss difficulty is low but requires knowledge of each new set of rules per league.
- Privilege the use of Sprites over Shapes (Rectangle, Circle, etc.)
- Less than 2Mb in total should be used.
- The minimum font size should be 36px.
- The choice of colors should take into account color-blind people as much as possible.
- .png and .jpg assets should be minified.
