Description

I did not test it by myself, no crypto, release build. Rust adds garbage, consts may be hardcoded, also it has state machine. This is guess number game where you need to guess from 0 to 1000, but you have only 3 attempts, so its impossible. You need to patch the game so you can win (patch variable that defines attempts count or anything else). Also you are playing against simple ai with algo similar to binary search but its not a binary search.

Labels ?

Control-flow obfuscation State machine / dispatcher Anti-disassembly Junk / garbage bytes

NeraWF on 2026-11-07 13:17: Fun little game — the state machine feels like a real terminal toy. Enjoyed the 'enemy AI' race. Thanks for sharing!
