On the Subject of Warning Signs
It’s much easier to not screw up if you haven’t screwed up already.
DANGER! This module shows a large sign to warn you about a specific hazard. To disarm the module, detach the sign by unscrewing its screws, one at a time, when the last seconds digit of the countdown timer is a valid digit.
Get three valid timer digits by following these steps:
- Construct a triangle as shown in the diagram by filling in the digits 0 to 9. Start with the first digit of the serial number at the top and continue in reading order, increasing each subsequent digit by 1. Wrap back to 0 if you exceed 9.
-
Receive a number from the table (continued on page 2) by using the hazard shown on the sign and the correct column following these rules:
- If the number of unsolved* modules is a multiple of 4, use column D.
- Else, if the number of unsolved* modules is a multiple of 3, use column A.
- Else, if the number of unsolved* modules is a multiple of 2, use column N.
- Otherwise, use column G.
- In the triangle, find all possible equilateral triangles in which the received number appears in a corner position. Then, locate the three numbers that don’t appear in corner positions of these triangles.
Unscrewing a screw is valid if the last seconds digit of the countdown timer matches one of these three numbers.
NOTE: Make sure to unscrew one screw for every valid timer digit. Moreover, the whole process cannot exceed 9 timer ticks from the first unscrew. Taking too long or unscrewing on an invalid timer digit will result in a strike.
