Wow, a lot of thought must have gone into this!

Right up my street and very challenging. I thought about but avoided binary for my number code grids- but only because I'm not clever enough! Base group beyond my maths, although I could pick them out and got meaning. I hope this gets the stars it deserves, I'm giving it 5/5 :)

good grid, looked hard but actually a lot easier than I thought has I spotted certain groups

Terrific stuff, thanks. Joy Division, yay! I did find the mix of upper and lower case in titles a bit confusing.

Brilliant use of number types. Very enjoyable!

That's Numberwang!

Very, very clever. I was beaten by both steps of solving the 7f hours group - didn't crack the code or know the answers! Great grid :)

very good, only worked em out cos I recognised the base's - and never heard of 3 of the TV series so couldnt get the connection.
