Can you crack the code? Dyslock is a pure logic puzzle inspired by the classic Mastermind. A secret code is hidden. Each clue shows a guess and its pegs: how many symbols are in the right place, how many are in the code but in the wrong place, and how many are not in the code at all. Compare the clues, take notes, rule out the impossible, and find the only code that fits. No guessing, no luck: every puzzle is solved by deduction.
