Phase 0 — Registration Phase 1 — Pre-Task Baseline Phase 2 — Collaborative Task Phase 3 — Post-Task Evaluation

Phase 2 — Collaborative Task

The experience comprised 13 unique puzzles organized into eight timed segments. Each segment has a maximum duration; if the timer reaches zero, any unsolved puzzles in that segment are skipped automatically. Puzzles integrate visual search, decoding, and object manipulation, requiring coordinated effort from all four team members.

▶ Official Deadly Hallows Walkthrough

Segment 1 max. 33 minPuzzle 1 — Arrows
Context shown on screen:
“Welcome!
Your first task is to solve a puzzle located on side 1 of the box.
Pay close attention to every detail, work together, and think ''outside'' the box.
Good luck, and let the journey begin!”
Description:
  • Symbols list: Side 1 of the box has a list of symbols.
  • Directional buttons: Side 2 of the box has four buttons with directional arrows (up, down, left, right).
  • Find clues: Find the symbols around the box; each symbol has an arrow next to it.
  • Solve: Press the arrows in the correct order according to the original list of symbols.

Hints:
  1. “[Side 1] What strange symbols are around this lock? I am sure I have seen them elsewhere.”
  2. “[Side 1] I have seen these triangles near the lock on other sides of the box. They must have a meaning.”
  3. “[Side 1] Decode the triangles and use the buttons on side 2 to input the code.”
Segment 2 max. 22 minPuzzle 2 — Maze
Side 1 — Trapdoor:
Solving Puzzle 1 opens a trapdoor revealing (a) a map, and (b) four codes used in subsequent puzzles to open boxes I, II, III, IV from the toolbox.
Trapdoor – Map

Trapdoor – Code II
Code II
Trapdoor – Code III
Code III

Code IV
Context shown on screen:
“Follow the map to solve 6 puzzles.
Decode the codes from the trapdoor using the toolbox after solving puzzle 2.
1 code → 1 box → 1 puzzle.
Puzzles 2 and 4 do not have boxes.
Please communicate these codes verbally rather than writing them down.”
Description:
  • Maze screen: Side 4 of the box has a circular screen with green rectangles and one red dot.
  • Directional buttons: The opposite side (side 2) has four buttons with directional arrows (up, down, left, right).
  • Solve: Use the arrows to move the red dot to the center of the maze twice. The red dot must avoid the moving green obstacles.
  • Teamwork: Ideally, one person looks at the maze and guides the person pressing the buttons, since the maze and buttons are on opposite sides of the box.

Hint Delivery System

Hints are delivered by the experimenter via a standardized, timer-driven protocol:

  • Timer trigger: Each hint level becomes available after a fixed elapsed time within the segment, ensuring consistent hint timing across all teams.
  • Three levels: Level 1 provides a mild directional nudge; Level 2 narrows the solution space; Level 3 provides near-explicit guidance.
  • Controlled skip: If a team has not solved a puzzle after receiving the Level 3 hint, the experimenter offers a controlled skip. The solution is shown and the team advances to the next segment, ensuring all teams cover the full puzzle sequence.
  • Game-state logging: All hint deliveries and skip events are logged with timestamps synchronized to the master acquisition clock.
