Secret Message Decoders

As long as there are secrets, there’ll always be a need for coded messages! Whatever your reason for needing to encode or decode vital information (don’t worry – we don’t need to know!), here’s our helpful guide to cracking those coded messages or creating your own!

Morse Code

Dot dot dot, dash dash dash! Get your message sent in a flash!

Phonetic Alphabet

Do you know your Foxtrot from your Tango? Or who Mike, Charlie and Oscar are?

Tap Code

Not all tippy tapping is Morse Code, you know! In the Tap Code, each letter is represented by two sets of dots; one set to determine the ROW, and then one set to determine the COLUMN.


A = . .     

J = .. .....

HELLO = .. ...   .. .   ... .   ... .   ... ....   

Pigpen Cipher

Dots and boxes are the key to getting you all code happy!

Semaphore Flag Decoder

Ahoy me hearties! This ‘ere decoder will help you pass your piratin’ exam with flying colours!

Code Wheel

Round and round we go, encoding letters to and fro! There are lots of ways to use this codewheel! Try a simple A=? to set the wheel for your whole message. Or, create an extra tricky code to crack by making your decoders turn the wheel different amounts for each letter or word! Start – A=F. Two clockwise C, Three anti-clockwise G etc.!
