L4668: ‘Impossible Construction’ by Serpent
Posted by Encota on 6 Aug 2021
What an enjoyable puzzle – thank you Serpent! And that hidden message encoded in the 36 letters of the central square, as advice to those who think that retiring won’t make them busier and will give them more free time (e.g. for puzzles):
“LEISURE RECEDES … ELSE RETIREMENT A SUCCESS“. So subtle, so subtle. It’s probably spelt out using Knight’s moves or something …

Cheers all,
Tim / Encota
