Complete step-by-step solution

Quick checklist

  • At least two players are present
  • The team has agreed on short signals
  • Someone has a free hand or bag slot for the reward
  • Drop lanterns or spare objects beside dangerous lamps so the team does not repeat a known bad press.

Verify it before moving on

After the reward appears, choose one carrier and take it to the correct receiver before the group disperses. A solved mechanism and a banked progression item are not always the same thing.
