 Puzzle ID: #47775 Fun: (2.68) Difficulty: (2.36) Category: Logic Submitted By: jtolley

You are a spy trying to gain access to a high profile building that contains very classified information. The only thing standing between you and those secrets is a keypunch security system containing the digits 1-9 that will open the door to the building. Your spy agency has provided you details about the order of the keys you need to enter:

1. Each digit is pressed once and only once.
2. No two consecutive digits are pressed consecutively.
3. The digits 2 and 4 are pressed 2nd and 4th in some order; the digits 6 and 8 are pressed 6th and 8th in some order.
4. The sum of the first 5 digits pressed is 19; the sum of the last 5 digits pressed is 27.

As you wonder why your agency couldn't just write down the sequence for you, you crack the code and enter the building.

What sequence of keys did you press on the security system to get into the building?

 odst6555 Aug 18, 2010 PRETTY WELL THOUGHT THRU crazy10man Sep 05, 2010 Very clever, but you lost me on your explanation. Looking at a phone keypad, it took me a minute to work out the pattern from your clues. Except for addition, I didn't need any other math skills to solve it. Looking forward to another teaser from you!!! Camillee Oct 03, 2010 Very intelligent indeed Illusionist Feb 19, 2011 This puzzle was VERY CHALLENGING, but one of my favorites indeed. Great teaser. oddrey Feb 21, 2012 Nice teaser! I failed to solve it because I misunderstood clue 2, so I think you could improve it by wording clue 2 a little more clearly.
