I just like to try to crack codes is all, because it's fun

Yeah me too!

I have the following codes for the Amiga version:

Fun: levels 6, 17, 30 and 31

Tricky: levels 1-3, 7-31

Taxing: all but level 29

Mayhem: all but level 1

As Shvegait said, the 8th letter runs between B and Q before changing the 9th letter.

If we convert this to Hex:

B = 0

C = 1

D = 2

E = 3

F = 4

G = 5

H = 6

I = 7

J = 8

K = 9

L = A

M = B

N = C

O = D

P = E

Q = F

Note: you could probably use these codes for the 9th letter too

So the position of Level 19 Mayhem (Code: OLIGAKNNIV) is NI, translate to hex: C7

I figure the hex codes from 7 tricky:

TRICKY:

7=43

8=53

9=63

and so on until:

18=F3

19=04

Then the cycle starts again.

Because of the way the numbers are moving you probably need to switch them around so it goes 9th-8th.

This makes the sequence aggree with Hex so you end up with 34,35 and 36.

Anyone else want to see what the other 8 numbers mean?
