Looks tricky at first, but once I realised what was going on, it all fell into place. Nice one!

Neat idea Blues! Original? Don't think I've come across this idea before....

Thanou Wiz.
In answer to your question I don't know if it's an original idea, but that begs the bigger question... Did Darwin copy Lamarck?
Did they have original thoughts but years and countries apart?
Obviously too long in the pub tonight for me !

not terribly hard but nice fun idea

I agree Dora, fun grid from Blues.

Agree with Dora the Explorer.
Nice idea, but far too easy.

Enjoyed it. Agree with the comments - not too tricky!

SpaggBol, Boots... Thank you for the feedback.
The idea was to have a nice easy grid to while away a minute or two, looks like mission accomplished.

Mission certainly was accomplished Blues, and after a very tough day I was glad to relax with it. Thanks.

Made me think! Well done.

Missed this earlier Bluesy, typically different effort fun too.

Nice grid thanks

Different and enjoyable
