As I've enjoyed Quick Word on the puzzles page I looked for something else quick to do. I decided to go for spatial puzzles this time and came across Jigsaw Planet. There are thousands of puzzles on there with anything from 4 to 500 pieces, and it's very easy to do (at least on my PC) and satisfying too. You can search by theme to select something you'd enjoy.
