It’s been a while since I did something totally off the wall, and the water filtration system in today’s jigsaw puzzle is not wall-mounted.
OK, that was a bad pun.
Seriously, though, at my day job we have lots of water filtration systems in place.
This kind of puts my little two-cylinder water system at home to shame!
One more thing – by request, I have included an extra “Tough” version that has rotating pieces. To play, in case you aren’t sure, left-click once to pick up a piece, right-click to rotate it 90º clockwise, then left-click to put it down.
Enjoy and please share!
