Paradox: A logic puzzle
Here's my newest thing. Inside this zip file is a 15x15 grid and 56 tetrominoes. The goal is to place all the tetrominoes on the grid so that it will have 4 fold rotational symmetry and 4 axes of reflection. You can rotate each tetromino as needed, but you can't flip them to use their mirror image. Good luck.

Must remember to get round to this. Have bookmarked it. Sounds good

I think I've cracked it. That was good fun! Once you realise a couple of important tricks it falls into place quite beautifully.

Glad you enjoyed it! I'd be interested to see if your solution was identical to mine and which tricks in particular you used.James S Roper wrote: ↑Sat Jun 27, 2020 10:14 am I think I've cracked it.
