Halloween at the Portal. The Hollow, a haunted cipher maze, is free to play until 2 November. Enter The Hollow

๐Ÿงญ This chain is also a 3D maze

The Redline is this same chain as a place you walk through. Each stage is a terminal beside a locked gate, and solving it opens the gate. The maze also hides data fragments with a bonus message you can only get there.

Your progress and score are the same either way, so you can start in one and finish in the other. If you want the maze to be a surprise, start there.

๐Ÿ“œ Briefing
The Redline is a train that does not stop, and its ciphers do not stand still either. The first gate gives you no key at all: you break it the way codebreakers always have, by counting which letters turn up most. After that, every gate uses a keyword, and every keyword is hidden in the answer before it.

Four gates. Keep an eye on "Keys you hold" at the top of each terminal.
  1. 1 Gate One - The Count
  2. 2 Gate Two - The Moving Shift ๐Ÿ”’ opens with stage 1's answer
  3. 3 Gate Three - The Mirror Shift ๐Ÿ”’ opens with stage 2's answer
  4. 4 Gate Four - Two Locks ๐Ÿ”’ opens with stage 3's answer
