Hi all, I'm not sure if this is the best section of the forum to post this on, so apologies if it's in the wrong place. I thought you might be interested to know that I've created a website to host some challenging logic, word and number mazes at:
https://www.webmazes.net
They are deliberately quite - okay, very - hard because that's the type of puzzle I personally enjoy attempting (but not always solving!).
I'm trying to make like-minded puzzle fans aware of its existence. No one has yet solved any of the the grade 5 difficulty mazes on the site, so these might be up your street if you really like a challenge!
