THE LAST SIGNAL
English · paper + pencil
THE COMPLETE EPISODE
A small mystery, ready for the table.
Reconstruct an inspection log, trace a light through mirrors, recover a coded message and restore a service sequence. Each paper unlocks one digit of the final panel.
No cutting, color printing or outside knowledge. Work alone or share the four papers. The first print edition is drafted and its puzzle logic has been checked; human playtesting and playing-time estimates are still pending.
FREE SAMPLE / TIDE
The Interrupted Log
Four keepers inspected four different pieces of equipment. Each keeper made exactly one inspection; each item was inspected exactly once; exactly one inspection occurred at each listed time. The names and equipment entries did not survive.
Keepers: Ada, Bram, Cora, Dev
Equipment: fog bell, lantern, radio, tide gauge
| Time | Seal | Keeper | Equipment |
|---|---|---|---|
| 20:00 | 2 | __________ | __________ |
| 20:10 | 7 | __________ | __________ |
| 20:20 | 4 | __________ | __________ |
| 20:30 | 9 | __________ | __________ |
Surviving notes
- The radio inspection occurred exactly 20 minutes after the tide gauge inspection.
- Ada's inspection was immediately after the lantern inspection.
- Bram inspected the fog bell.
- The fog bell was inspected later than the lantern.
- Dev's inspection occurred earlier than Cora's.
- Ada did not inspect at 20:10.
Immediately after means the next listed time. Earlier and later need not mean adjacent times.
Mira's reset instruction
The TIDE digit is the printed record seal beside Cora's inspection time.
Need a nudge?
Hint 1 - where to start
Start with equipment. Only two pairs of times can fit the tide gauge and radio.
Hint 2 - narrow it down
Try 20:00/20:20 and 20:10/20:30. Put the lantern before the fog bell in the remaining slots.
Hint 3 - a stronger direction
A tide gauge check at 20:10 would put the lantern at 20:00, then Ada at 20:10 - forbidden. Use the other pair and place Bram, Ada, Dev and Cora.
Reveal the full solution
The order is Dev / tide gauge at 20:00; Cora / lantern at 20:10; Ada / radio at 20:20; Bram / fog bell at 20:30. Cora's record seal is 7.
The alternative tide gauge/radio pair forces Ada into the time ruled out by clue 6. The other clues then fix every remaining entry.
