sudoku

sucks me in and spits me out on a regular basis. What bugs me most about it is that there's not enough room in the empty squares to jot down all the possible numbers. So you end up rubbing out, writing over, making clots of scribbles in the corners of squares that take away half the satisfaction of solving it - and makes it a lot messier than it needs to be.

Sudoku purveyors take note: it's a design thing. How hard would it be to enlarge the squares, and give users enough white space to work on? Until you do, I'm boycotting you.
