BOSS DOG is Retro6400's first NFT series and the first NFT to include a color-coded cryptograph message along with a de-coder key within the image. YOU must determine how to use the key to solve the mystery! "Boss Dog is hound of special pedigree. He hides a simple message, that you can plainly see. Solve the secret phrase, unwrap the mystery, and you will secure your place, in crypto history!" First, Second, and Third place winners will be designated as Retro6400 "Masterminds" and their names will be listed on the Retro6400.com site's Hall of Fame. Each subsequent NFT in the series will get progressively harder to solve.
