We got the binary file snakes.exe. Which was someting like snake game. By disassembling the exe in binary ninja, I found SHOW_FLAG() function is called on certain condition.

As it is completely offline challenge i.e flag is present in binary itself, There are 2 options to solve this either reverse engineer the condition or patch the binary to always call SHOW_FLAG() function. We choose the easy way to patch the binary. and got the flag.
