Module consists of screen that shows a stage counter.
Stage counter increments every 3 solved unignored modules.

Press the screen to listen to the current stage’s code. If the screen wasn’t pressed on any stage (except 00)th then module will strike. You
may listen to the code several times.

Starting from 01st stage, change this code by following the rules below:

  • Take the current code modulo 19 then add (previous answer % 6 + 1)th SN symbol, converted from base-36. Take the sum modulo 11 and call it operation number.
  • Using the operation number, find the current answer where:
    • a - current code,
    • b - previous answer (0001 for stage 01),
    • c - previous code (0001 for stage 01).
    • Replace any 0000 with 0001.
Number: Answer:
0 a+(2b%a)+(4c%b)
1 b+(3c%b+abc)
2 log2(abc+bc+c)+ln(abc+ab+a)
3 a·sin(b+c)cos(bc)
4 c·coslog2(ab)
5 (a+b+c)·((-a)%b%(b%c-a2))
6 abc3+a2+b2+c29+a+b+c3
7 3a(1-e-bc)
8 (a+b+c)e
9 31a+1b+1c
10 a·log(m+1)(n+1)(p+1), where:
m - digital root of bc
n - digital root of ac
p - digital root of ab

At the end, sign and decimals mnust be dropped, and answer
is considered mod 10000.

At the very end, check the
answer for 0 digits. Use this table:

IN THIS ORDER!
If ... digit is 0, add:
4th: 375 3rd: 24 2nd: 713 1st: 4016

Modulo the number by 10000 and replace 0s by 1s.

Submit that using:

If the submitted answer is
incorrect, the module will go into
recovery mode.

Recovery Mode

To get some information from Recovery mode, you’ll have to input
a 3-digit code:

  • To immediately exit from Recovery Mode, input 555.
  • You can also get the “halfway” answer. For example, if you had 30 stages, the sequence would be: 15 22 26 28 29. Input 888.
  • To get the read of some particular stage, use the table below:
Stage ab a0 0b 00
Input 1ab 2a2 33b 444
