Cheat Engine

Hi
I have rebus that I need help with.
I'm trying to write program that will read values from data file created by one custom game. Problem is that same values can be represented in different array of bytes and because size of this array is always 12 bytes long and game uses zlib1.dll I thought those values are compressed but they do not start with 78 9C as it should be with zlib compression.
for example:
DE 61 4C 81 62 4C FB D4 F2 A5 B3 7E is equal value 20 dec in game
CA 4C A6 9F 1C 7F 8B 65 06 BB 59 60 is also equal value 20 dec in game.
if I copy and past one of those array of bytes at special location in data file I'll get value 20. If I change one byte I'll get 0

some other examples made by game:
72 25 45 23 4E B6 CF 4D 92 87 BE DC = 2409
5C DE AB 35 41 99 9A 80 10 11 58 CA = 2579
49 E9 E2 0D 2B 81 C0 CF B7 16 1D F2 = 0
06 95 F7 4E 4A AE 3C 89 FA 6A 08 B1 = 0

How is this even possible?
Does anybody know how this works?
Cheat engine is not giving me anything.

Zlib has no requirement that it has a header. It can be skipped
But try finding what reads it and then follow the disassembly to figure out what is going on

Interesting. What's the name of this game. Is it public?

It's a game for slot machines, it's not public
