On the Subject of The Missing Letter
I wonder where it went… Maybe it needed to go P? Maybe it went to find a new golf T? Or maybe it just wants to find U.
- This module consists of a 5×5 grid of letters. Every letter of the English alphabet should be present except one.
- Find the letter that’s not present on the module and perform the calculation in Table A to get a number. Take this number’s absolute value modulo 5 and add 1 to it. This number will be called n.
- Find the nth word in Table B under the missing letter on the module and spell it out using the buttons to disarm the module.
- If an incorrect letter is pressed at any time, a strike will be issued and the module will clear any input it has received so far.
B = number of batteries; BH = number of battery holders; P = number of ports; PP = number of port plates; I = number of indicators; LI = number of lit indicators; UI = number of unlit indicators; S# = serial number character in the #th position (A=1, B=2, ... Z=26); A# = alphabetic position of the #th letter on the module in column reading order (A1-5, B1-5, etc.)
