Forever In the Rough – 10 of Diamonds

It’s sad when you realize that you are not playing with a full deck.  In fact, my Molnár deck only has 2 cards, the Ace of Diamonds (Nothing Yet Designs Release: 13 January 2025, 12:00 PM EST) and the 10 of Diamonds.  Someday, I’d like to have a full Molnár deck or at least a royal flush.

10 of Diamonds was designed by László Molnár and used by Gergő Prémecz as his exchange puzzle at the 40th International Puzzle Party (IPP).  It is a 2D tray-packing puzzle made from red and white acrylic.  The 5 unique pieces each consist of 2 connected diamonds.   The front of the tray is designed to look like a playing card, the 10 of diamonds in fact, with a rectangular space to hold the diamonds.  It’s nicely made by Mr. Puzzle with the details inlaid in red on a white background.  The backside has a second challenge, where the pieces need to fit within a hexagonal area.  The backside also has the puzzle information etched on the tray.

A single-sided version made from wood was originally entered in the Nob Yoshigahara Puzzle Design Competition in 2020 where it won a Top 10 Vote Getter Award.  Now the puzzle has double the fun of the award-winning version.

Both sides of the tray are challenging.  Since neither side is fully packed you would think it would be easier but you would be mistaken.  There is quit a bit of unused space that makes it more difficult to determine where pieces need to go.  And although the backside has 2 solutions, the front side has a single solution.  You may find it rough.  It may take you forever.  But you’ll enjoy solving it.  At least that’s what I kept telling myself.

Along the way, you may encounter situations where the pieces can be crammed in by force but this would not be the solution and you should not be tempted to use force.  The puzzle has been designed so that all the pieces can be nicely placed with no force.

10 of Diamonds is a nice challenge and I’m looking forward to seeing how László completes the royal flush.
