[Crypto Challenge @cryptochallenge]

Hi Everyone, we will be launching a bonus clue - targeting to get that out this week! Be on the lookout...

[Crypto Challenge @cryptochallenge]

BETA Clue #4: Make a guess on which domino tiles correspond to the digits 0 – 9, and find out how these ultimately translate into letters.

[Crypto Challenge @cryptochallenge]

Crypto Challenge BETA Clue #3: Formally, the cipher is based on a mapping E from the set {A,...,Z,0,...9} onto the set of domino tiles.

Anyone making progress on Crypto Challenge BETA? We will be releasing our next clue in 1 week... #cryptochallenge

[Crypto Challenge @cryptochallenge]

Clue #2: Encryption and decryption don't require any arithmetic and can be done by hand, using letter and domino tiles. #cryptochallenge
