Weekly Challenges used to be a competition. It was started by H, and a new topic would be announced each week with the reward of hacker plan for the person with the most points (challenge and submissions are posted on Repl Talk) at the end of the month. At first, they were beginner-friendly but gradually grew more complex, which led to more and more people leaving the challenges, eventually causing its death. Zave claims to have come up with the idea, but no-one knows for sure.
