Your mission

Work together to set the satellite receiving panel.

Welcome to the satellite signal desk. A training log has signal meanings but no complete legend for the receiving panel. Your team has the original records on the table. First recover five pieces of information, then use the final plan to set the satellite receiving panel. Keep every result beside its badge so another teammate can check your reasoning.

How your team will think

Infer a one-to-one legend and apply recovered instructions to a control panel.

Write each recovered instruction beside its signal. Keep the legend and the panel’s starting settings visible as you apply the instructions and check the final configuration.

Set up in one room

  1. Print the six player sheets and two record sheets for each team. Keep answers and hints with the host.
  2. Lay out Unlabelled legend, Call log, the remaining clue sheets and the final plan. All task records are printed inside the sheets; no extra prop is needed.
  3. After each clue, pass roles one seat clockwise. With two players, combine Reader with Recorder and Checker with Builder. With five or six, add a second checker and a source finder; everyone explains one decision.

Bring to the table

  • One complete player set and record set per team
  • One pencil per child
  • One adult host with the answer and hint pages
