Truthly I’ve never heard of this before, however £100,000 has just be won in a cryptic treasure hunt.
What caught my eye was the winner is Andy Darley, a name which rang a bell. Now whilst I can’t confirm that it is the same one, his site does have Perplex City ads and used to run a Perplex City Card Swap.
If it is the same one, well done!
Two more seconds of detective work pretty much confirm that it is the same one, as the winners username is astro_random, which matches that of one on Andy’s website.
