﻿ 100 Levels of Defusal — Keep Talking and Nobody Explodes Module

## On the Subject of 100 Levels of Defusal

i like short manuals ._.

#### Section A-B

tl;dr: Solve some modules until it’s unlocked.

#### Section C - MAIN

1. For each letter displayed: Find number pair (lo, hi) in Table A.
2. For ALL combinations of lo #s: multiply pairwise, sum them = A
• (e.g.) lo #s are a,b,c: A = ab+ac+bc = a(b + c) + bc
• (e.g.) lo #s are a,b,c,d: A = ab+ac+ad+bc+bd+cd = a(b + c + d) + b(c + d) + cd
3. Repeat for hi #s, sum = B
4. Compute: C = (A+B) × level# (15 if no level#)
5. Convert: C to base 6
6. Replace: 0 -> 6 (for all digits!!!)
7. Take the rightmost (display length + 1) digits (prepend 0s if there are fewer)
8. For each adjacent pair of digits* in C, find corresponding letter in Table A.

* Step 8: Adjacent pairs of digits refers to C’s digits: 1st & 2nd, 2nd & 3rd, etc.

#### Table A

Table is symmetric; order does not matter.
0 1 2 3 4 5 6 A A E E I O U A B C D F G H E C J K L M N E D K P Q R S I F L Q T V W O G M R V X Y U H N S W Y Z

#### Section D - EXAMPLES

Example 1: Shown on display is LVY. Level 2.

X lo# hi# proc(low#) proc(hi#) L 2 4 2×4+2×5+4×5 4×5+4×6+5×6 V 4 5 Y 5 6
• (A + B) × #level = (38 + 74) × 2 = 22410 = 10126
• 0 -> 6: 10126 -> 1612 -> [16][61][12] -> HHC

Example 2: 23406 obtained, Output: requires 4 letters

• 0 -> 6: 23406 -> 2346
• +leading 0s: 2346 -> 02346 -> [02][23][34][46] -> EKQW

Example 3: Shown on display is ZYV. Level 10.

• (A + B) × 10 = 170010 = 115126
• 0 -> 6 and rightmost (3 + 1) digits: 11512 -> 1512 -> [15][51][12] -> GGC
