"See you in the morning. Make sure you're not late," my grandfather said. Then, he handed me this photo and left. I was worried I wouldn't be able to solve my grandfather's puzzle, so I immediately set my attention to it. Late into the evening, I was struggling still and thought I would need to call him and sheepishly ask for an explanation.

Then, I had a simple idea. I grabbed a World Book Encyclopedia and set to work. Just a minute later and I knew exactly what time to meet my grandfather.

What time was I supposed to meet him?

Hoping that this 'simple idea' is not too simple... You need to meet him at:

SIX AM (6am)


Interpret the hands of each clock using flag semaphore code. The positions of each pair of hands translate in sequence to S - I - X.

Use the initials of the locations beneath them (AMM) purely to clarify that the meeting time is ante meridiem (am) i.e. in the morning (as per the title) rather than the evening...

  • $\begingroup$ Correct! I suppose it was "too" simple. I had some ideas for more layering, but decided to leave it at this.. $\endgroup$

    $\begingroup$ @DanielC Not necessarily - at first I debated whether the numbers meant anything ciphery... To solve it I had to discard information and work out what was really important. Still puzzleworthy, just a quick one in the end :) $\endgroup$
