• Start with a combination that uses several different colors to get more information from the first clue.
• Keep track mentally (or on paper) of which colors you've confirmed and in which position, so you won't repeat useless moves.
• If a color doesn't show up in any clue after trying it, rule it out for the next rows.
• Don't change more than two pegs per attempt: that way you can better measure the effect of each change on the result.
