Status: planned. The Corridor Challenge is part of Read-To-Earn, which has not launched. There is nothing to enter.
The idea
A corridor of eight numbered doors. Behind each is a challenge tied to something you have read — a question that cannot be answered by skimming the blurb. Work through the doors in order and the reward comes at the end.
It exists to make Read-To-Earn resistant to the obvious cheat. Rewarding "finished a book" rewards clicking to the last page; rewarding "answered eight questions that require having read it" does not. The challenge is the proof, not the game.
It ships when Read-To-Earn and Proof-Of-Read do, and not before.
