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
0	A	A	E	E	I	O	U
1	A	B	C	D	F	G	H
2	E	C	J	K	L	M	N
3	E	D	K	P	Q	R	S
4	I	F	L	Q	T	V	W
5	O	G	M	R	V	X	Y
6	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#)
1	L	2	4	2×4 +2×5 +4×5	4×5 +4×6 +5×6
2	V	4	5
3	Y	5	6
Sum				A=38	B=74

• (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
