A few years ago I made my PhD in to a pen-and-paper puzzle book. Here it is, in full. Contact me if you want it in pdf format.
Complete the puzzles by deciding which grid-squares to cover with each
For each puzzle you are given some tiles and a grid. Each tile can only be placed in a certain row or column, and no four tiles are allowed to meet. It’s challenging but the whole book is doable. Good luck!
