I like to spend my time doing crosswords and sudokus. It keeps me occupied and out of trouble. Today I was thinking, many different people approach puzzles very differently. Some people solve the pop culture-related crossword clues first, and then work away at the rest. Some people can spot eliminations much easier horizontally than vertically in sudoku. I'd be interested in playing sudokus and crosswords and what-have-yous in an environment which would track how I solved the particular puzzle, and then accumulate a database of players and strategies and methods, and then group the players together and see if they're similar at all. I wonder if I'd be chummy with someone who solves sudokus very similarly to how I do, or if I'd have anything in common with them at all.
