How it works
- Each puzzle shows a 32-bit little-endian ARM64 instruction encoding.
- Your guess is assembled by the real GNU
as— running inside a tiny Linux VM booted in your browser via v86 (an x86 emulator compiled to WebAssembly). The first page load fetches a pre-baked memory snapshot of the booted VM so the assembler is ready in a second or two. - If your assembled bytes match the target, you win. Multiple mnemonics may be valid for the same encoding.
- Per-bit feedback shows which bits of your guess matched the target.
