I can sit for hours and focus on sudoku, killer sudoku, and KenKen. The rules are clear and self-contained, and they don't require external knowledge or vocabulary to complete (unlike crosswords, for example, where I might get stuck if I don't know someone's last name). What other puzzles are like this?
