I've always liked jigsaw puzzles, solving them when I was a kid and a teenager. Don't get the chance to these days unfortunately, but I'm still interested in them and I sometimes do an online one.
The other day I found this YouTube channel called Karen Puzzles presented by Karen Kavett and I'm hooked! Nerd factor: high. Approved.
Here's just a few especially interesting videos that I found on this channel. Let us know your favourites.
This puzzle is probably my all time favourite as it's recursive. I mean, just look at it!
And here's the solid red one. A big challenge, but Karen shows how to solve it.
And a spherical one!
