PUZZLE:  The alarm keyboard

  • This is a “mastermind-type” puzzle.
  • The worker’s fingers have left their traces on these buttons: 0 2 5 6 7
  • But the code is of 6 digits; this means one of the numbers is used twice. (Some of the buttons are dirtier than others, but this is misleading). When you enter a series of numbers, the system reacts indicating how many of these were correct AND in the right position.  (If a number is correct but the position is incorrect the system will disregard it).You can deduce the solution several ways, in a few steps: 657072
