Very good. I like those grids where you think you’ve got no chance, but then you see it and ‘crack it.’

I really hope so, Mr/ Mrs Obs. That's always my intention, even if mine sometimes (always) look a bit nasty. Because I love eureka moments and last minute, Indiana Jones' hat type moments myself; they're the most fun to solve. So I want that for other people :) Thanks so much for your feedback and your grids

cool cross-overs

scramble a code? hmmm

there's a wikipedia page that explains the term and I found 2 other refs to "scramble the code" on t'internet, so I think it can pass?

I liked this one

Excellent grid, very well constructed.

This is going to be one of my favourites!:-)

Tricky one. I couldn’t figure it.
