Anyone else have some favorite semi-difficult puzzles that they like to do? Another example would be the classic "Who own the fish?" puzzle with the various nationalities, cigars, drinks, and pets with the list of clues: http://www.mathsisfun.com/logicpuzzle.html Apparently these are referred to as Einstein Puzzles.
The puzzles where you have to rearrange tiles to complete a picture, 3x3 and 4x4 and pretty trivial, but 6x6 and 8x8 can take some time, especially if the pictures hard
The "Einstein puzzle" label for what I've always known as "Logic puzzles" from Dell seems to be a more recent thing, I think.
I've usually got a few of the Dell combo "magazines" in the bathroom, logic puzzles, sudoku, et cetera of various difficulties and varieties. Number crossword puzzles can be fun too.
