In reply to Gazmataz:
fifteenquared is a great site.
I don't think cryptic crosswords are what cb is looking for unless he gets very, very good at them, or is willing to carry them across from one two minute break to another. The quick crossword, on the other hand... to do that would be a challenge, but not an absurdly difficult one. It is the third puzzle I do every day, after Worldle then Wordle, neither of which I am finding at all boring so far.
Cryptic crosswords can take up your whole life, so to manage this I just do the Everyman on Sundays. It is one of the easier ones out there, but still takes me an hour or two of effort followed by a conundrum or two that rattles around in my head until sometime in the afternoon when I confer with my mum who by then has had a go herself.
For cb, how about codewords? I often turn to this site when I have a minute or two to spare:
