Puzzles tips

🧩

Encode a message in binary and share it as a sequence of 0s and 1s. Solvers must convert each 8-bit group to a letter to decode the message.

💡

For easier puzzle difficulty, separate each byte with a space (01001000 01101001). For harder, remove all spaces (0100100001101001).

🔍

Escape room design: print the binary on paper with each group separated, then let players decode it using a reference table.

🎮

Video game easter eggs often hide messages in binary. Use this tool to decode suspected binary strings you find in game files or loading screens.
