Welcome to the inventor relay bench. Each recovered pulse may turn several dials, so every test record matters. Your team has the original records on the table. First recover five pieces of information, then use the final plan to configure the relay machine. Keep every result beside its badge so another teammate can check your reasoning.
In an unordered pair, a word cannot be assigned by its left/right position. Use the overlap with another pair.
Hint 3
Give each signal a different word, check every training example and only then decode the received message in its printed order.
Reveal host answer
HOLD-RIGHT
A consistent one-to-one mapping satisfies every training example. Use the complete mapping to read the two-signal message in order. Result: HOLD-RIGHT.
2. Record
Hint 1
Start with the status field in Part labels.
Hint 2
The tag links an item to a bay; rows in separate records need not line up.
Hint 3
Keep only entries meeting every status test. Follow each printed join to the report field; do not guess from row position.
Reveal host answer
EAST
Check source status first, then join the matching tag. The useful information comes from separate records, not their printed row order. Result: EAST.
3. Builder
Hint 1
Find the three people, the three items and the forbidden pairings.
Hint 2
Each item is used once. A person ruled out of two items must have the third.
Hint 3
Place the most restricted person, remove that item from the others, then use the remaining rule. Read the target person only after checking all pairs.
Reveal host answer
0
Dee has Wheel; Mo has Lever; Xin has Relay. Xin's item gives 0. Result: 0.
4. Diagram
Hint 1
Compare the same numbered position in the two strips.
Hint 2
A difference belongs to a pair of positions and is counted once, even when both shapes differ.
Hint 3
Mark every changed pair, check the unmarked pairs, then count your marks. Ignore titles and box outlines.
Reveal host answer
3
Different positions are 2, 5, 8. There are 3 differences. Result: 3.
5. Test
Hint 1
Find the symbol key and the message strip.
Hint 2
Use the same key every time a symbol repeats. Read the message in its printed order.
Hint 3
Write the complete decoded word, check every symbol, then use the conversion row for that exact word.
Reveal host answer
1
The decoded word is TEST; its row gives 1. Result: 1.
6. Final
Needs: Signal, Record, Builder, Diagram, Test
Hint 1
Find the starting states, dial order and pulse-card key.
Hint 2
Each selected vector lists turns for every dial. Several different cards can affect the same dial.
Hint 3
Add one dial column at a time to its starting state, wrap around the three-state loop, then check that all five pulse cards were used.
Reveal host answer
A1-B2-C0-D1-E1
Select one pulse card for each of the five badge results. Add the turns by dial column to the printed starting states and wrap each total around 0, 1, 2. The checked configuration is A1-B2-C0-D1-E1; each pulse pair has equal size and total turns, so its shape does not identify the correct choice.
Suggested timeline
3 minutes: Read the opening. Show the evidence record and choose starting roles.
5 minutes: Solve Signal. Offer one hint at a time and rotate roles after checking.
5 minutes: Solve Record. Offer one hint at a time and rotate roles after checking.
5 minutes: Solve Builder. Offer one hint at a time and rotate roles after checking.
5 minutes: Solve Diagram. Offer one hint at a time and rotate roles after checking.
5 minutes: Solve Test. Offer one hint at a time and rotate roles after checking.
7 minutes: Build the checked five-dial configuration using all five results.
3 minutes: Read the ending. Ask each teammate to explain one rejected alternative.
Pause whenever the group needs a break. This is a planning estimate.
