Forty!
On June 7th I turn 40! To celebrate I wanted to construct a puzzle based upon the number 40. I hope you enjoy it!

Happy birthday in advance and thank you for this wonderful gift! It said that I was the 40th solver, but maybe that was some more 40-trickery. Lovely ruleset. Thank you

Took me a minute to realise what 40 had to do with this puzzle (I was being a bit slow!)
But a 28 minute solve wasn't too shabby. Lovely puzzle for a Sunday morning. Thanks jamncheez and happy birthday!

Happy 40th! Very nice puzzle.
When I finished the puzzle, I was amazed to see that my solving time was 40:40. (I swear that I didn't plan that.)
