Hi everyone,
in the episode of 'The Search' when they are all in India, one of the challenges requires the teams to break an old traditional code using the knuckle joints in the hands. Each knuckle joint represents one letter of the alphabet but does anyone know what this code is called? Or the history of the code or anything?
Thanks!!

Forget it everybody, I found the answer. Sorry about this! I have no idea how to delete this topic so if anyone does now I would be grateful if you could delete it for me! Thanks
