Sudoku guides
Three short guides: one to get you solving, one for when a grid stalls, and one on getting a good print.
Few people ever get taught sudoku. You pick up a grid somewhere, work out the rule in about a minute, and then either find your own way through or give up. Plenty of people who would enjoy it give up at that point because nobody showed them the first move.
The first guide assumes no prior knowledge. The second assumes you can finish a medium grid and want to know what to do when a hard one stalls. The third covers the printer settings that decide whether a grid is pleasant to write on.
